ANALYSIS
This ordinance repeals those provisions of Title 26 — Building Code — of the
Los Angeles County Code that had incorporated by reference portions of the 2016
Edition of the California Building Code and replaces them with provisions incorporating
by reference portions of the 2019 California Building Code, published by the California
Building Standards Commission, with certain changes and modifications.
State law requires that the County's Building Code contain the same
requirements as are contained in the building standards published in the most recent
edition of the California Building Code. State law allows the County to change or modify
these requirements only if it determines that such changes or modifications are
reasonably necessary because of local climatic, geological, or topographical conditions.
The changes and modifications to requirements contained in the building
' standards published in the 2019 California Building Code that are contained in this
ordinance are based upon express findings, contained in the ordinance, that such
changes are reasonably necessary due to local climatic, geological, or topographical
conditions.
This ordinance also makes certain modifications to the administrative provisions
of Title 26 and to certain chapters of Title 26 that relate to subjects not covered by the
California Building Code.

1613.6 Seismic design provisions for hillside buildings
1613.6.1 Purpose.
The purpose of this Section is to establish minimum regulations for the design
and construction of new buildings and additions to existing buildings when constructing '
such buildings on or into slopes steeper than one unit vertical in three units horizontal
(33.3 percent). These regulations establish minimum standards for seismic force
resistance to reduce the risk of injury or loss of life in the event of earthquakes.
1613.6.2 Scope.
The provisions of this Section shall apply to the design of the lateral -force -
resisting system for hillside buildings at and below the base level diaphragm. The
design of the lateral -force -resisting system above the base level diaphragm shall be
in accordance with the provisions for seismic and wind design as required elsewhere in
this Chapter.
Exceptions:
1. Non -habitable accessory buildings and decks not supporting or supported
from the main building are exempt from these regulations. I
HOA.102624620.1 35
2. Additions to existing buildings that do not exceed 10 percent of the
existing floor area provided that the addition is being supported completely by the
existing foundation.
1613.6.3 Definitions.
For the purposes of this Section certain terms are defined as follows:
BASE LEVEL DIAPHRAGM is the floor at, or closest to, the top of the highest
level of the foundation.
DIAPHRAGM ANCHORS are assemblies that connect a diaphragm to the
adjacent foundation at the uphill diaphragm edge.
DOWNHILL DIRECTION is the descending direction of the slope approximately
Iperpendicular to the slope contours.
FOUNDATION is concrete or masonry that supports a building, including
footings, stem walls, retaining walls, and grade beams.
FOUNDATION EXTENDING IN THE DOWNHILL DIRECTION is a foundation
running downhill and approximately perpendicular to the uphill foundation.
HILLSIDE BUILDING is any building or portion thereof constructed on or into a
slope steeper than one unit vertical in three units horizontal (33.3 percent). If only a
portion of the building is supported on or into the slope, these regulations apply to the
entire building.
PRIMARY ANCHORS are diaphragm anchors designed for and providing a
direct connection as described in Sections 1613.6.5 and 1613.6.7.3 between the
Idiaphragm and the uphill foundation.
HOA.102624620.1 36
SECONDARY ANCHORS are diaphragm anchors designed for and providing a
redundant diaphragm to foundation connection, as described in Sections 1613.6.6 and
1613.6.7.4.
UPHILL DIAPHRAGM EDGE is the edge of the diaphragm adjacent and closest
to the highest ground level at the perimeter of the diaphragm.
UPHILL FOUNDATION is the foundation parallel and closest to the uphill
diaphragm edge.
1613.6.4 Analysis and design.
1613.6.4.1 General.
Every hillside building within the scope of this Section shall be analyzed,
designed, and constructed in accordance with the provisions of this Chapter. When the '
code -prescribed wind design produces greater effects, the wind design shall govern, but
detailing requirements and limitations prescribed in this Section and all referenced
Sections shall be followed.
1613.6.4.2 Base level diaphragm -downhill direction.
The following provisions shall apply to the seismic analysis and design of the
connections for the base level diaphragm in the downhill direction.
1613.6.4.2.1 Base for lateral force design defined.
For seismic forces acting in the downhill direction, the base of the building shall
be the floor at, or closest to, the top of the highest level of the foundation.
HOX102624620.1 37
1613.6.4.2.2 Base shear.
In developing the base shear for seismic design, the response modification
coefficient (R) shall not exceed 5 for bearing wall and building frame systems. The total
base shear shall include the forces tributary to the base level diaphragm, including
forces from the base level diaphragm.
1613.6.5 Base shear resistance for primary anchors
1613.6.5.1 General.
The base shear in the downhill direction shall be resisted through primary
anchors from diaphragm struts provided in the base level diaphragm to the foundation.
1613.6.5.2 Location of primary anchors
' A primary anchor and diaphragm strut shall be provided in line with each
foundation extending in the downhill direction. Primary anchors and diaphragm struts
shall also be provided where interior vertical lateral -force -resisting elements
occur above and in contact with the base level diaphragm. The spacing of primary
anchors and diaphragm struts or collectors shall in no case exceed 30 feet (9,144 mm).
1613.6.5.3 Design of primary anchors and diaphragm struts
Primary anchors and diaphragm struts shall be designed in accordance with the
requirements of Section 1613.6.8.
1613.6.5.4 Limitations.
The following lateral -force -resisting elements shall not be designed to resist
seismic forces below the base level diaphragm in the downhill direction:
' 1. Wood structural panel wall sheathing;
HOA.102624620.1 38
2. Cement plaster and lath;
3. Gypsum wallboard; and
4. Tension -only braced frames.
Braced frames designed in accordance with the requirements of
Section 2205.2.2 may be used to transfer forces from the primary anchors and
diaphragm struts to the foundation provided lateral forces do not induce flexural
stresses in any member of the frame or in the diaphragm struts. Deflections of frames
shall account for the variation in slope of diagonal members when the frame is not
rectangular.
1613.6.6 Base shear resistance for secondary anchors
1613.6.6.1 General. I
In addition to the primary anchors required by Section 1613.6.5, the base shear
in the downhill direction shall be resisted through secondary anchors in the uphill
foundation connected to diaphragm struts in the base level diaphragm.
Exception: Secondary anchors are not required where foundations extending in
the downhill direction spaced at not more than 30 feet (9,144 mm) on center extend up
to and are directly connected to the base level diaphragm for at least 70 percent of the
diaphragm depth.
1613.6.6.2 Secondary anchor capacity and spacing
Secondary anchors at the base level diaphragm shall be designed for a minimum
force equal to the base shear, including forces tributary to the base level diaphragm, but

Building Official are on deposit and guaranteed for payment, or a letter of credit is
issued by such a financial institution.
J103.7.3 Amount of security.
The amount of security shall be based on the number of cubic yards of material
' in either excavation or fill, whichever is greater, and the cost of all drainage or other
protective devices or work necessary to eliminate potential flooding and geotechnical
hazards. That portion of the security valuation based on the volume of material in either
excavation or fill shall be computed as follows:
100,000 cubic yards or less — 50 percent of the estimated cost of grading work.
Over 100,000 cubic yards — 50 percent of the cost of the first 100,000 cubic
yards plus 25 percent of the estimated cost of that portion in excess of 100,000 cubic
ay rds.
When the rough grading has been completed in conformance with the
requirements of this Code the Building Official may, at his or her discretion, consent to
a proportionate reduction of the security to an amount estimated to be adequate to
Iensure completion of the grading work site development, or planting remaining to be
HOA.102624620.1 106
performed. The costs referred to in this Section shall be as estimated by the Building
Official.
J103.7.4 Conditions.
All security shall include the conditions that the principal shall:
1. Comply with all of the provisions of this Code, applicable laws, and
ordinances:
2. Comply with all of the terms and conditions of the grading permit, and
3. Complete all of the work authorized by the permit.
J103.7.5 Term of security.
The term of each security shall begin upon the filing with the Building Official, and
the security shall remain in effect until the work authorized by the grading permit is '
completed and approved by the Building Official.
J103.7.6 Default procedures.
In the event any grading for which a permit has been issued is not completed in
accordance with the approved plans and specifications for said work or with all terms
and conditions of the grading permit the Building Official may declare that a default has
occurred. The Building Official shall give notice thereof to the principal and surety or
financial institution executing the security, or to the owner in the case of a cash bond or
assignment.
The Building Official may thereafter determine the work that is necessary to
mitigate any hazardous or unsafe conditions on the site and cause such work to be
performed. I
HOA.102624620.1 107
Where the security consists of a bond or instrument of credit, the surety or
financial institution executing the security shall be responsible for the payment of all
costs and expenses incurred by the Building Official in causing such work to be
performed, up to the full amount of the security. In the case of cash security or
assignment, the Building Official may pay all costs and expenses incurred in causing
such work to be performed from the funds deposited and return any unused portion of
such deposit or funds to the person making said deposit or assignment.
J103.7.7 Right of entry.
The Building Official or the authorized representative of any surety company or
financial institution furnishing the security shall have access to the premises described
Iin the permit for the purpose of inspecting the work.
In the event of default, as described in Section J103.7.6, the surety or financial
institution furnishing the security, or the Building Official or any person employed or
engaged on the behalf of any of these parties shall have the right to go upon the
premises to perform the mitigation work, as described in Section J103.7.6.

Geological
The greater Los Angeles/Long Beach region is a
densely populated area having buildings constructed
over and near a vast array of earthquake fault systems
capable of producing major earthquakes, including but
not limited to the 1994 Northridge Earthquake. The
proposed amendment is intended to prevent occupants
from being trapped in a building and to allow rescue
workers to easily enter after an earthquake.
1507.3.1
Geological
Section amended to require concrete and clay tiles to be
Installed over solid structural sheathing boards only, due
to the increased risk of significant earthquakes in the
County. The changes in Section 1507.3.1 are needed
because there were numerous observations of tile roofs
pulling away from wood framed buildings following the
1994 Northridge Earthquake. The Structural Engineers
Association of Southern California ("SEAOSC") and the
Los Angeles City Joint Task Force committee findings
indicated significant problems with tile roof due to
inadequate design and/or construction. Damage was
observed where sheathing beneath the tile roofs was
not nailed adequately or the nails were not attached on
each side of each tile or the nail just pulled out over a
period of time because the shank of the nails were
smooth. Therefore, the amendment is needed to
minimize such occurrences in the event of future
significant earthquakes.

Northridge and the 1971 Sylmar earthquakes.
1613.7
Geological
The inclusion of the importance factor in this equation
and
has the unintended consequence of reducing the
1613.7.1
minimum seismic separation distance for important
facilities such as hospital, school, police, and fire
station, etc., from adjoining structures. The deletion of
the importance factor from Equation 12.12-1 will ensure
that a safe seismic separation distance is provided.
This amendment is a continuation of an amendment
adopted during previous code adoption cycles, and is
necessary due to the increased risk of significant
earthquakes in the County.
1613.7.2
Geological
Damage to one- and two-family dwellings of light frame
construction resulting from the Northridge Earthquake
may have been partially attributed to vertical
irregularities common to this type of occupancy and
construction. In an effort to improve quality of
construction and incorporate lessons learned from
studies after the Northridge Earthquake, the
modification to ASCE 7, Section 12.2.3.1, by limiting the
number of stories and height of the structure to two
stories will significantly minimize the impact of vertical
irregularities and concentration of inelastic behavior
from mixed structural systems. This amendment is a
continuation of an amendment adopted during previous
code adoption cycles, and is necessary due to the
increased risk of significant earthquakes in the County.
1613.7.3
Geological
The SEAOSC and Los Angeles City Joint Task Force
investigated the performance of concrete and masonry
construction with flexible wood diaphragm failures after
the Northridge earthquake. It was determined that
continuous ties are needed at specked spacing to
control cross grain tension in the interior of the
diaphragm. Additionally, subdiaphragm shears need to
be limited to control combined orthogonal stresses
within the diaphragm. Recognizing the importance and
need to continue the recommendation made by the task
force, but also taking into consideration the improved
HOA.102624620.1 148
HOA.102624620.1 149
performance and standards for diaphragm construction
today, a proposal to increase the continuous tie spacing
limit to 40 ft in lieu of 25 ft and to use 75 percent of the
allowable code diaphragm shear to determine the depth
of the sub -diaphragm in lieu of the 300 plf is deemed
appropriate and acceptable. The Los Angeles region is
within a very active geological location. Due to the
frequency of this type of failure during previous
significant earthquakes, various jurisdictions within this
region have taken these additional steps to prevent roof
or floor diaphragms from pulling away from concrete or
masonry walls. This amendment is a continuation of an
amendment adopted during a previous code adoption
cycles.
1613.7.4
Geological
This change is to implement the provisions in ASCE 7-
16. This provision allows for a limited value to be used
in the seismic design of a building when certain criteria
are met. The current provision does not clearly state
the criteria and has created misapplications of this
section. It is necessary to adopt this provision now to
avoid further misinterpretation of the intent of the 5 story
limit, and how the height of the building is measured.
The Los Angeles region is within a very active
geological location. When applying the story height
limit, mezzanines need to be considered as floor levels
due to the added mass, overturning forces, and the
variation in shear wall stiffnesses that are created.
ASCE 7-16 provisions need to be incorporated into the
Code to ensure that new buildings and additions to
existing buildings are designed and constructed in
accordance with the purpose and intent of the Building
Code.
1613.8
Geological
Section is added to improve seismic safety of buildings
Topographical
constructed on or into hillsides. Due to the local
topographical and geological conditions of the sites
within the Los Angeles region and their probabilities for
earthquakes, this technical amendment is required to
address and clarify special needs for buildings
constructed on hillside locations. A SEAOSC and
Los Angeles City Joint Task Force investigated the
performance of hillside building failures after the
Northridge earthquake. Numerous hillside failures
resulted in loss of life and millions of dollars in damage.
These criteria were developed to minimize the damage

cycles.
1704.6
Geological
The language in Sections 1704.6 of the California
Building Code permits the owner to employ any
registered design professional to perform structural
observations with minimum guidelines. However, it is
important that the registered design professional
responsible for the structural design has thorough
knowledge of the building he/she designed. By
requiring the registered design professional responsible
for the structural design, or their designee, who was
involved with the design to observe the construction, the
quality of the observation for major structural elements
and connections that affect the vertical and lateral load
resisting systems of the structure will greatly be
increased. Additional requirements are provided to help
clarify the role and duties of the structural observer and
the method of reporting and correcting observed
deficiencies to the Building Official. This amendment is
a continuation of an amendment adopted during
previous code adoption cycles, and is necessary due to
the increased risk of significant earthquakes in the
County,
1704.6.1
Geological
With the higher seismic demand placed on buildings
and structures in this region, the language in sections
1704.6.1, Item 3, of the California Building Code would
permit many low-rise buildings and structures with
complex structural elements to be constructed without
the benefit of a structural observation. By requiring a
registered design professional to observe the
construction, the quality of the observation for major
structural elements and connections that affect the
vertical and lateral load resisting systems of the
structure will be greatly increased. An exception is
provided to permit simple structures and buildings to be
excluded. This amendment is a continuation of an
amendment adopted during previous code adoption
cycles, and is necessary due to the increased risk of
si nificant earthquakes in the County.
HOA.102624620.1 150
1705.3
Geological
Results from studies after the 1994 Northridge
Earthquake indicated that a significant portion of the
damage was attributable to lack of quality control during
construction resulting in poor performance of the
building or structure. Therefore, the amendment
restricts the exceptions to the requirement for special
inspection. This amendment is a continuation of an
amendment adopted during previous code adoption
cycles, and is necessary due to the increased risk of
significant earthquakes in the County.
1705.12
Geological
In Southern California, very few detached one- or two-
family dwellings not exceeding two stories above grade
plane are built as "box -type" structures specially for
those in hillside areas and near the oceanfront. Many
with steel moment frames or braced frames, and/or
cantilevered columns, can still be shown as "regular"
structures by calculations. With the higher seismic
demand placed on buildings and structures in this
region, the language in section 1705.12, Item 3, of the
California Building Code would permit many detached
one- or two-family dwellings not exceeding two stories
above grade plane with complex structural elements to
be constructed without the benefit of special
inspections. By requiring special inspections, the quality
of major structural elements and connections that affect
the vertical and lateral load resisting systems of the
structure will be greatly increased. The exception
should only be allowed for detached one- or two-family
dwellings not exceeding two stories above grade plane
assigned to Seismic Design Categories A, B, and C.

These amendments are intended to carry over critical

Increased confinement is critical to the integrity of such

provided when certain thresholds are exceeded. In
addition, this amendment carries over from the UBC a
critical provision for the design of concrete shear walls.
It essentially limits the use of very highly gravity -loaded
walls from being included in the seismic load resisting
system, since their failure could have a catastrophic
effect on the building. Furthermore, this amendment
was incorporated into this Code based on observations
from the 1994 Northridge Earthquake. Rebar placed in

some instances to have popped out of the slab due to
HOA.102624620.1 154

The overdriving of nails into the structural wood panels
still remains a concern when pneumatic nail guns are
used for wood structural panel shear wall nailing. Box
nails were observed to cause massive and multiple
failures of the typical 3/8 -inch thick plywood during the
1994 Northridge Earthquake. The use of clipped head
nails continues to be restricted from use in wood
structural panel shear walls where the minimum nail
head size must be maintained in order to minimize nails
from pulling through sheathing materials. Clipped or
mechanically driven nails used in wood structural panel
shear wall construction were found to perform much
worse in previous wood structural panel shear wall
testing done at the University of California Irvine. The
existing test results indicated that, under cyclic loading,
the wood structural panel shear walls were less energy
absorbent and less ductile. The panels reached
ultimate load capacity and failed at substantially less
lateral deflection than those using same -size hand -
driven nails. This amendment reflects the
recommendations by the SEAOSC and the Los Angeles

2306.3
Force that investigated damage to buildings and

recommended reducing allowable shear values in wood
2308.6.5.2
structural panel shear walls or diaphragms that were not

substantiated by cyclic testing. That recommendation
2308.6.5.1
was consistent with a report to the Governor from the

Seismic Safety Commission of the State of California
2308.6.5.2
recommending that code requirements be "more
thoroughly substantiated with testing." The allowable
shear values for wood structural panel shear walls or
diaphragms fastened with staples are based on
monotonic testing and do not take into consideration
that earthquake forces load shear wall or diaphragm in a
repeating and fully reversible manner. In September
2007, limited cyclic testing was conducted by a private
engineering firm to determine if wood structural panels
fastened with staples would exhibit the same behavior
as wood structural panels fastened with common nails.
The test result revealed that wood structural panels
fastened with staples demonstrated much lower
strength and stiffness than wood structural panels
fastened with common nails. It was recommended that
the use of staples as fasteners for wood structural panel
shear walls or diaphragms not be permitted to resist
seismic forces in structures assigned to Seismic Design
Categories D, E and F unless it can be substantiated by
cyclic testing. Furthermore, the cities and
unincorporated areas within the Los Angeles region
have taken extra measures to maintain the structural
integrity of the framing of shear walls and diaphragms
designed for high levels of seismic forces by requiring
wood sheathing be applied directly over the framing
members and prohibiting the use of panels placed over
gypsum sheathing. This amendment is intended to
prevent the undesirable performance of nails when

With the higher seismic demand placed on buildings

called upon to resist over half of the seismic loading
imposed on simple buildings or structures. Without a

elements such as non-structural concrete slab floors,
wood floors, etc. The purpose of this amendment is to
limit the use of the exception to structures assigned to

ANALYSIS
This ordinance repeals those provisions of Title 30 — Residential Code — of the
Los Angeles County Code, which had incorporated by reference portions of the 2016
Edition of the California Residential Code, and replaces them with provisions
incorporating by reference portions of the 2019 California Residential Code, published
by the California Building Standards Commission with certain changes and
modifications.
State law requires that the County adopt ordinances that contain the same
requirements as are contained in the building standards published in the California
Residential Code. State law allows the County to change or modify these requirements
only if it determines that such changes or modifications are reasonably necessary
because of local climatic, geological, or topographical conditions.
' The changes and modifications to requirements contained in the building
standards published in the 2019 California Residential Code that are contained in this
ordinance are based upon express findings, contained in the ordinance, that such
changes are reasonably necessary due to local climatic, geological, or topographical
conditions.

Explanation of Amendment
R301.1.3.2
Geological
Los Angeles County is prone to seismic activity due
to the existence of active faults in the Southern
California area. After the 1994 Northridge
Earthquake, the Wood Frame Construction Joint Task
Force recommended that the quality of woodframe
construction needed to be greatly improved. The
Task Force recommended that structural plans be
prepared by the engineer or architect so that plan
examiners, building inspectors, contractors, and
special inspectors may logically follow and construct
the seismic force -resisting systems as presented in
the construction documents. For buildings or
structures located in Seismic Design Category Do, D1,
DZ, or E that are subject to a greater level of seismic
forces, the requirement to have a California licensed
architect or engineer prepare the construction
documents is intended to minimize or reduce
structural deficiencies that may cause excessive

damage or injuries in woodframe buildings.
Involvement of a registered professional will minimize
the occurrence of structural deficiencies such as plan
and vertical irregularities, improper shear transfer of
the seismic force -resisting system, missed details or
connections important to the structural system, and
the improper application of the prescriptive
requirements of the California Residential Code.
R301.1.4
Geological
Due to the local topographical and geological
Topographical
conditions of the sites within the greater Los Angeles
region and their susceptibility to earthquakes, this
technical amendment is required to address and
clarify special needs for buildings constructed on
hillside locations. A joint Structural Engineers
Association of Southern California (SEAOSC) and
Los Angeles City Joint Task Force investigated the
performance of hillside building failures after the
Northridge Earthquake. Numerous hillside failures
resulted in loss of life and millions of dollars in
damage. These criteria were developed to minimize
the damage to these structures and have been in use
by the City and County of Los Angeles for several
ears.
R301.2.2.6
Geological
Los Angeles County is prone to seismic activity due
to the existence of active faults in the Southern
California area. Due to the high geologic activities in
the Southern California area and the necessary
higher level of performance required for buildings and
structures, this local amendment limits the type of
irregular conditions as specified in the 2019 California
Residential Code. Such limitations are recommended
to reduce structural damage in the event of an
earthquake. The County of Los Angeles and cities in
this region have implemented these extra measures
to maintain the structural integrity of the framing of
the shear walls and all associated elements when
designed for high levels of seismic loads.

from ASCE 7 and the International Building Code
would permit equipment weighing up to 400 lbs. when
mounted at 4 feet or less above the floor or attic level

This amendment will not allow unprotected openings
R3O2.1(2)
(openings that do not resist the spread of fire) to be in
the exterior wall of a residential building that is
located on a property line. This amendment is
necessary due to local climatic conditions. The hot,
dry weather conditions of late summer in combination
with the Santa Ana winds creates an extreme fire
danger. Residential buildings with unprotected
openings located on a property line may permit fires
to spread from the inside of the building to adjacent
properties and likewise from exterior properties to the

R401.1
Geological
Los Angeles County is prone to seismic activity due
to the existence of active faults in the Southern .
California area. Wood foundations, even those that
are preservative -treated, encounter a higher risk of
deterioration when contacting the adjacent ground.
The required seismic anchorage and transfer of
lateral forces into the foundation system necessary
for 2 -story structures and foundation walls could
become compromised at varying states of wood
decay. In addition, global structure overturning
moment and sliding resistance is reduced when
utilizing wood foundations as opposed to
HOA.102623614.1
40
HOA.102629614.1 41
conventional concrete or masonry systems.
However, non-occupied, single-story storage
structures pose significantly less risk to human safety
and may utilize the wood foundation guidelines
specified in this Chapter.
R403.1.2
Climatic
Los Angeles County is prone to seismic activity due
R403.1.3.6
Geological
to the existence of active faults in the Southern
R403.1.5
California area. These amendments require
Figure
minimum reinforcement in continuous footings and
R403.1.5
stepped footings to address the problem of poor
performance of plain or under-reinforced footings
during a seismic event. These amendments
implement the recommendations of SEAOSC and the
Los Angeles City Joint Task Force resulting from their
investigation of the 1994 Northridge Earthquake.
Interior walls can easily be called upon to resist over
half of the seismic loading imposed on simple
buildings or structures. Without a continuous
foundation to support the braced wall line, seismic
loads would be transferred through other elements
such as non-structural concrete slab floors, wood
floors, etc. Requiring interior braced walls to be
supported by continuous foundations is intended to
reduce or eliminate the poor performance of buildings
or structures.
R404.2
Climatic
No substantiating data has been provided to show
Geological
that wood foundations are effective in supporting
structures and buildings during a seismic event while
being subject to deterioration caused by the presence
of water and other materials detrimental to wood
foundations in the soil. Wood foundations, when they
are not properly treated and protected against
deterioration, have performed very poorly and have
led to slope failures. Most contractors are typically
accustomed to construction in dry weather in the
Southern California region and are not generally
familiar with the necessary precautions and treatment
of wood that makes it suitable for both seismic events
and wet applications. With the higher seismic
demand placed on buildings and structures in this
region, coupled with the dryer weather conditions, it is
the intent of this amendment to reduce or eliminate
potential problems resulting from the use of wood
footings and foundations.
HOA.102629614.1 41
R501.1
Geological
Due to the high geologic activities in the Southern
California area and the necessary higher level of
performance required for buildings and structures,
this local amendment limits the potential anchorage
and supporting frame failure resulting from additional
weight. There is no limitation for weight of
mechanical and plumbing fixtures and equipment in

amendment that a registered design professional be
required to analyze if the floor support is adequate
and structurally sound.
R503.2.4
Geological
Section R502.10 of the Code does not provide any
Figure
prescriptive criteria to limit the maximum floor
R503.2.4
opening size, nor does Section R503 provide any
details to address the issue of shear transfer near
larger floor openings. With the higher seismic
demand placed on buildings and structures in this
region, it is important to ensure that a complete load
path is provided to reduce or eliminate potential
damage caused by seismic forces. Requiring
blocking with metal ties around larger floor openings
and limiting opening size is consistent with the
requirements of Section R301.2.2.2.5.

cities in this region have taken extra measures to
maintain the structural integrity of the framing of the
shear walls when designed for high levels of seismic
loads by eliminating single top plate construction.
The performance of modern day braced wall panel
construction is directly related to an adequate load
path extending from the roof diaphragm to the

R602.10.2.3
Geological
The greater Los Angeles region is a densely
populated area having buildings and structures
constructed over and near a vast array of fault
systems capable of producing major earthquakes,
including, but not limited, to the 1994 Northridge
Earthquake. Plywood shear walls with high aspect
ratio experienced many failures during the Northridge
Earthquake. This proposed amendment specifies a
minimum braced wall length to meet an aspect ratio
consistent with other sections of the California
Residential Code, and to assure that new buildings
and additions to existing buildings are designed and
constructed in accordance with the scope and
objectives of the California Residential Code. This is
intended to improve the performance level of
buildings and structures that are subject to the higher
seismic demands and reduce and limit potential
damage to property. This proposed amendment
reflects the recommendations by SEAOSC and the
Los Angeles City Joint Task Force that investigated
the poor performance observed during the 1994
Northridge Earthquake.

were observed to cause massive and multiple failures
of typical 3/8-inch thick plywood during the Northridge
Earthquake. This change to the minimum lap splice
requirement is consistent with Section 12.16.1 of ACI
318-11. This amendment is a continuation of
amendments adopted during prior Code adoption
cycles.

Geological
3/8" thick 3 ply-plywood shear walls experienced
R602.10.6.4
many failures during the Northridge Earthquake. The
poor performance of such shear walls in the 1994
Northridge Earthquake was investigated by SEAOSC
and the Los Angeles City Joint Task Force. The
County of Los Angeles and cities in this region have
taken extra measures to maintain the structural
integrity of the framing of the shear walls when
designed for high levels of seismic loads. The
proposal in which "washers shall be a minimum of
0.229 inch by 3 inches by 3 inches in size" is,
consistent with Section R602.11.1 of the California
Residential Code and Section 2308.3.2 of the
California Building Code. This amendment is a
continuation of amendments adopted during prior
Code adoption cvcle.
R606.4.4
Geological
Los Angeles County is prone to seismic activity due
to the existence of active faults in the Southern
California area. The addition of the word "or" will
prevent the use of unreinforced parapets in Seismic
Design Category Do, D1 or D2, or on townhouses in
Seismic Design Category C.

Geological
Los Angeles County is prone to seismic activity due
to the existence of active faults in the Southern
California area. Reinforcement using longitudinal
wires for buildings and structures located in high
seismic areas is not as ductile as deformed rebar.
Having vertical reinforcement closer to the ends of
masonry walls help to improve the seismic
erformance of masonry buildings and structures.
R803.2.4
Geological
Section R802 of the Code does not provide any
prescriptive criteria to limit the maximum size of roof
openings, nor does Section R803 provide any details
to address the issue of shear transfer near larger roof
openings. With the higher seismic demand placed on
buildings and structures in this region, it is important
to ensure that a complete load path is provided to
reduce or eliminate potential damage caused by
seismic forces. Requiring blocking with metal ties
around larger roof openings and limiting the size of
openings is consistent with the requirements of
Section R301.2.2.2.5.
R905.3.1
Geological
Due to the increased risk of significant earthquakes in
Los Angeles County, this amendment requires
concrete and clay tiles to be installed over solid
structural sheathing boards only. The changes in
Section R905.3.1 are needed because there were
numerous observations of tile roofs pulling away from
wood framed buildings following the 1994 Northridge
Earthquake. SEAOSC and the Los Angeles City
Joint Task Force committee findings indicated
significant problems with tile roof due to inadequate
design and/or construction. Damage was observed
where sheathing beneath the tile roofs was not nailed
adequately, or the nails were not attached on each
side of each tile, or the nail just pulled out over a
period of time because the shank of the nails were
smooth. This amendment is needed to minimize
such occurrences in the event of future significant
earthquakes.

R1001.3.1
Geological
Los Angeles County is prone to seismic activity due
to the existence of active faults in the Southern
California area. The performance of
fireplaces/chimneys without anchorage to the
foundation has been observed to be inadequate
during major earthquakes. The lack of anchorage to
the foundation results in overtum or displacement.
AS106.1
Geological
Los Angeles County is prone to seismic activity due
to the existence of active faults in the Southern
California area. Due to the high geologic activities in
the Southern California area and the necessary
higher level of performance required for buildings and
structures, this local amendment limits the use of
strawbale walls for structural purposes for buildings or
structures located in Seismic Design Category Do, D1,
D2, E or F. There is limited testing results available
on the structural application of strawbale walls,
particularly for seismic resistance. Since these
provisions are specific to one- and two-family
residential buildings, it is of the utmost importance
that homes be resilient in the event of an earthquake
and built using proven construction methods and
materials. The remaining provisions allowing for the
use of strawbale walls for nonstructural applications
will still be permitted.

CONDITION
EXPLANATION
220.41
Climatic
The County of Los Angeles is a
densely populated area with
varying and occasionally
immoderate temperatures and
weather conditions. This creates
the need for highly efficient
buildings to reduce demand on the
electrical grid and, in tum, reduce
the use of fossil fuels and improve
air quality. The proposed
amendment will provide a cost-
effective means for homeowners to
increase energy savings and
reduce the demand on the
electrical grid by requiring the
installation of an energy storage
system for current or future use
with minimal need for additional
construction and modification of
the existin electrical s stem.

302.7.1 General compliance. Whenever the Building Official
determines by inspection that, as a result of inadequate construction or bracing to resist
horizontal forces, an existing parapet or appendage attached to and supported by an
exterior wall of a building is likely to become a hazard to life or property in the event of
I
earthquake disturbance, and such parapet or appendage is not an immediate hazard or
HOA.102603147.1 2
danger, as described in Section 102, the Building Official may provide the owner of the
building or other person or agent in control of the building, where such parapet or other
appendage exists, with a written notice specifying the hazards and the inadequacies of
the construction or bracing. The owner of the building or other person or agent in

hazard in the event of accidental human impact, as described in Section 2406.4 of the
Building Code, and such installation does not comply with the provisions for glazing in
such locations, the Building Official may provide the owner of the building or other
person or agent in control of the building where such glazing exists with a written notice
