Agenda Item: `1 E
To: Mayor and City Council
From: David Martin, Director of Planning and Community Development
Scott Ferguson, Chief of Fire Department
Subject: Adopt a Resolution Making Findings of Local Climatic, Geological and
Topographical Conditions and an Ordinance Adopting the 2013 California
Building Standards Codes and Santa Monica Local Amendments
Recommended Action
Staff recommends that the City Council:
1. Adopt the attached resolution that provides findings of local climatic,
geological and topographical conditions as required to adopt local
amendments to the California Building Standards Code.
2. Introduce for first reading the attached ordinance that adopts the 2013
California Building Standards Code and Santa Monica local amendments to
the California Building Standards Code.
3. Instruct staff to file the adopted resolution and ordinance with the California
Building Standards Commission following the second reading of the
ordinance but at least 30 days before the effective date of the Codes.
Executive Summary
The 2013 Edition of the California Building Standards Code, together with local
amendments and findings, are presented here for City Council adoption. The
resolution, presented as Attachment A, sets forth the local climatic, geological and
topographical conditions and findings that are required to support the adoption of the
local technical code amendments. The ordinance, presented as Attachment B, sets
forth the adoption of the 2013 Edition of the California Building Standards Code and the
Santa Monica local amendments to the California Building Standards Code. If the
Council adopts the proposed resolution and the accompanying ordinance, they would
become effective on January 1, 2014.
1
All local Santa Monica amendments to the State technical codes are necessary
because of local climatic, geological and topographical conditions. These amendments
provide for higher orders of seismic safety, fire safety, occupant safety and
environmental efficiencies. As required by State law, all local amendments are more
stringent than State law's requirements and each amendment is justified with
appropriate findings.
•,
Pursuant to the Health and Safety Code, the California Building Standards Code applies
throughout the State of California. This set of 2013 building standards incorporates by
reference various model codes with amendments created by applicable State agencies.
The California Building Standards Commission publishes amended codes once every
three years. One hundred and eighty days later, all cities and counties must follow the
published standards unless the local jurisdiction amends them as allowed by law.
Cities and Counties may make amendments to the California Building Standards Code
based on local climatic, geological and topographical conditions, provided that the
amendments are not less restrictive than the State requirements. For amendments to
be effective, the local governing body must make specific findings that any one or more
of the aforementioned conditions is applicable, approve an ordinance adopting the
amendments, and file a copy of the express findings and the local ordinance with the
California Building Standards Commission. These requirements apply to both new and
previously adopted local amendments.
Summary of the 2013 California Building Standards Code
Title 24 of the California Code of Regulations is also known as the California Building
Standards Code where adoption of these State codes is part of staff's recommendations
to Council. The 2013 California Building Standards Code includes the following:
• Title 24, Part 2:
• Title 24, Part 2.5:
• Title 24, Part 3:
• Title 24, Part 4:
2013 California Building Code
2013 California Residential Code
2013 California Electrical Code
2013 California Mechanical Code
• Title 24, Part 5:
2013 California Plumbing Code
• Title 24, Part 6:
2013 California Energy Code
• Title 24, Part 9:
2013 California Fire Code
• Title 24, Part 11:
2013 California Green Building Standards Code
Building and Fire Life Safety Commission Action
The Building Officer and the two Assistant Fire Marshals held two public meetings with
the Building and Fire Life Safety Commission to present proposed local amendments
and findings. On September 5 and September 12, 2013, the Commission reviewed the
staff recommendations and provided recommended changes to the technical content of
staff's proposed amendments. Staff agreed with the Commission's recommendations
and incorporated them into this recommendation to the Council. At the end of the
hearing process, with one exception, the Commission unanimously recommended that
the City Council adopt the proposed resolution and accompanying ordinance.
However, the Commission did not agree with the Fire Department's recommendation
that the City continue defining high -rise buildings as all buildings above 55 -feet. State
law defines high rise buildings to be above 75 -feet. Santa Monica has maintained a
lower 55 -feet requirement for many decades. The Fire Department believes that
maintaining a height limit of 55 -feet is necessary to effectively fight fires, especially
during times of emergencies such as during and after a sizable earthquake. Like all
other local amendments proposed by staff, this proposed local amendment is fully
supported by local climate and geological conditions in that Santa Monica is earthquake
prone and Santa Ana winds can produce large and rapidly spreading fires that are
difficult to control. Additionally many other jurisdictions (e.g. El Segundo, Newport
Beach, the County of Orange to name a few) have this similar 55 -feet limit. Of course, if
a project's special circumstances justify deviation from this 55 -feet requirement, the
project applicant could apply for such deviation through the alternate means and
methods application process.

City of Santa Monica Amendments
Staff recommends Council adopt the proposed local amendments to the 2013 Building
Standards Code as they are more stringent than the State building codes, and because
they are justified by local climatic, geological or topographical conditions. Recognizing
the specific seismic conditions of Santa Monica with known earthquake faults in the
City, and the special environmental conditions of the City's beach community, all
recommended amendments are presented with a higher order of seismic safety, fire
protective measures, occupant safety and environmental efficiencies. The majority of
the amendments, particularly for the Building Code and Residential Code, were
discussed, conceived, and authored by the collaborative group of building officials in
Los Angeles County. All of Building and Safety's engineering staff participated in each
of the committees of this collaborative group and staff finds that the technical
suggestions of the collaborative group are applicable to Santa Monica and thus are
recommending them for adoption.
Amendment for Residential Electric Vehicle Charging
A new Section 8.106.100 is proposed as a local amendment that would address issues
for electric vehicle charging in multi - family dwellings. The proposed amendment would
provide tenants in multi - family dwellings a means to install electric vehicle charging
equipment with a dedicated electrical meter so they may enjoy off -peak charging rates
as offered by Southern California Edison. The amendment would apply to new
electrical services in both new and existing multi - family dwellings including mixed -use
multi - family buildings. The main technical components of the amendment are increased
capacity considerations for the electrical distribution equipment and requirements for
installation of additional multi -meter equipment dedicated and ready for installation of
future electric vehicle chargers. Staff is presenting this proposal with a local climatic
justification whereby this amendment will promote a lower contribution to greenhouse
gases with the benefit of reduced effect to the local environment. The requirements of
this proposed amendment are cost effective with minimal increase in equipment and
labor costs.
11
Staff proposes this amendment in part to address concerns raised by the community
where tenants of multi - family buildings having experienced the inability to install
charging equipment, thereby limiting their options to purchase electric vehicles. While
the proposal does not address the issues of assigned parking, allowance to add
equipment in common areas and association regulations that may exists between a
tenant and an owner or association of multi - family occupancies, it does streamline the
process for future access to install charging equipment. National and state codes do
not have the provisions of the proposed amendment. Should the amendment be
approved, Santa Monica would be the first to implement such standards.
Energy Code Amendments
The proposed ordinance does not include any amendments to the 2013 State Energy
Code. As proposed, the State Energy Code would be operative in Santa Monica
without any local energy amendments. Consistent with state law, local energy
amendments adopted by the Council during the previous (2010) Building Code cycle,
such as solar pool heating and solar ready roofs would no longer be enforceable
beyond January 1, 2014.
This is because local amendments to the State Energy Code must first be approved by
the California Energy Commission and accompanied by a cost effectiveness study. The
software necessary to model cost effectiveness studies has not yet been certified by the
State Energy Commission. Accordingly, staff will return to Council with energy related
local amendment proposals once the software programs are certified by the State. It is
anticipated that staff will present local energy amendments to the Council in the first half
of 2014.
Summary of Changes and Recommended Amendments
Changes to Article VIII, Building Regulations, of the Santa Monica Municipal Code were
made including updating references to previous building code editions, amendments to
the State codes and addition or revisions of local amendments.
R,
The changes in the set of recommended codes incorporate the building industry's latest
technical provisions and safety standards and offer the highest order of building and
construction safety regulations, or the "Standard of Care ". Major changes in the
California Building Standards Code that continue to promote this Standard of Care are:
• Re- classification of seismic zones whereby portions of the City of Santa Monica
will now be classified in a higher Seismic Design Category E affecting areas
north of an approximate boundary between mapped points at Wilshire Boulevard
and Ocean Avenue, and Ocean Park Boulevard and Centinela Avenue.
• Major revisions introduced by the State Architect which adopts significant
portions of the 2010 Americans with Disabilities Act (ADA) Standards with
California amendments.
• Expanded regulations of children's play structures to cover all non - residential
occupancies.
• Authorize fire officials to require address numbers to be posted and maintained
at multiple locations.
• New requirement that receptacles outlets replaced in residential occupancies
must be tamper resistant and have arc -fault circuit interrupter protection.
• Prohibition of unvented heaters in residential occupancies.
• Addition of chapters in the State Plumbing Code to include gray water and
rainwater catchment standards.
• Increase in energy efficiency from current State Energy Standards to
approximately 25% in single - family occupancies, 14% in multi - family
occupancies and 30% in non - residential occupancies.
• Expanded scope in the State Green Building Standards Code to now include all
residential occupancies and most non - residential occupancies.
• The State Green Building Standards Code will apply to existing non - residential
buildings for additions of 1,000 square feet or more, and to alterations of
$200,000 or more.
The majority of the amendments recommended for Council's approval are technical in
nature and are intended to provide a higher order of structural safety during a seismic
0
event. In particular, many of the requirements in the State Building and Residential
Codes that reference Seismic Design Categories D, E and F - Santa Monica's seismic
zone classifications are modified to provide more stringent requirements. A summary of
the proposed amendments is provided for each adopting code.

program shall designate the portions of the work to have special inspection, the name or
names of the individuals or firms who are to perform the special inspections and
indicate the duties of the special inspectors, including any required nondestructive
testing.
The Building Officer, or when approved by the Building Officer, the owner, the
engineer or architect of record, or an agent of the owner, but not the contractor or any
other person responsible for the work, shall employ the special inspector. When
structural observation is required, the inspection program shall name the individuals or
firms who are to perform structural observation and describe the stages of construction
at which structural observation is to occur. The inspection program shall include
samples of inspection reports and provide time limits for submission of reports.
(f) Preconstruction Meetings. The Building Officer may require the permit
holder to participate in a preconstruction conference prior to the completion of plan
review and permit issuance to review the plans and specifications for adequacy and
sufficiency of details and conformance to building standards and interpretations.

program of Section 9.04.10.02.450 shall not expire while that project remains on the
waiting list for a building permit.
(2) No action may be taken on an application after expiration. Plans and other
data submitted for review may thereafter be returned to the applicant or destroyed
25
purged by the Building Officer. To obtain a permit, applicants shall submit a new
application, new submittal documents and pay a new plan review fee. All applicable
standards in effect at the time of the new application shall then apply to the project.
(i) Extensions. The Building Officer may grant one six -month extension of
the one -year plan check time period set forth in subsection (h)(1) above, if the applicant
demonstrates that:
(1) No changes have been made or will be made to the original plans and
specifications except as required by the original plan review; and
(2) No pertinent laws or ordinances have been amended subsequent to the
date the original application was filed which would cause the development project at

by placing the circular core section in a compression testing machine with the mortar
bed joint rotated fifteen degrees from the axis of the applied load. The mortar joint
tested in shear shall have an average ultimate stress of twenty psi (138 kPa) based on
the gross area. The average shall be obtained from the total number of cores made. If
test.specimens cannot be made from cores taken, the shear value shall be reported as
zero.
126
SECTION 44. Section 8.72.080 of the Santa Monica Municipal Code is hereby
amended as follows:
8.72.080 Analysis and design.
(a) General. Every building within the scope of this Chapter shall be
analyzed, designed and constructed in conformance with the Building Code except as
modified herein. No alteration of the existing lateral force - resisting or vertical load-
carrying system shall reduce the strength or stiffness of the existing structure.
When any portion of a building within the scope of this Chapter is constructed on
or into a slope steeper than one unit vertical in three units horizontal, the lateral- force-
resisting system at and below the base level diaphragm shall also comply with the
provisions of Chapter 8.20 of this Code.
When the portion of the building that requires strengthening is limited to the
underfloor area of the first floor and that area is used only as an uninhabited crawl
space, strengthening requirements shall also comply with the provisions of Chapter 8.68
of this Code.
(b) Scope of Load Path. This Chapter requires the alteration, repair,
replacement or addition of structural elements and their connections to meet the
strength and stiffness requirements herein. The lateral load path analysis shall include
the resisting elements and connections from the wood diaphragm above any soft, weak
or open front wall lines to the foundation soil interface or reinforced concrete slab or
masonry wall supporting elements below. The lateral load path analysis for added
structural elements shall also include evaluation of the allowable soil bearing and lateral
127
pressures in accordance with the Building Code.
When an open front, weak or soft wall line exists due to parking at the ground
level of a two -level building and the parking area is less than twenty percent of the
ground floor level, then only the wall lines in the open, weak or soft directions of the
enclosed parking area, need comply with the provisions of this Chapter.
(c) Design Base Shear. The design base shear in a given direction shall be
equal to the base shear that the Building Code requires for new buildings.
(d) Vertical Distribution of Forces. The total seismic force shall be
distributed over the height of the structure in accordance with the Building Code except
that distribution of force by story weight shall be permitted for two -story buildings. The
value of R used in the design of any story shall be less than or equal to the value of R
used in the given direction for the story above.
(e) Weak Story Limitation. The structure shall not exceed thirty feet in height
or two levels if the lower level strength is less than sixty -five percent of the story above.
Existing walls shall be strengthened as required to comply with this provision unless the
weak level can resist a total lateral seismic force of three times the design force
prescribed in subsection (c) of this Section.
The story strength for each level of all other structures shall be a minimum of
eighty percent of the story above.
(f) Story -Drift Limitation. The calculated story drift for each retrofitted level
shall not exceed the allowable deformation compatible with all vertical load resisting
elements and the story drift limitations of the Building Code. The calculated story drift
shall not be reduced by the effects of horizontal diaphragm stiffness but shall be
increased when these effects produce rotation.
128
The effects of rotation and soil stiffness shall be included in the calculated story
drift when lateral loads are resisted by vertical elements whose required depth of
embedment is determined fined by l formulas uch Fermula (6 1) and (6 2) On based
on the requirements of Section 1806.8.2 1807.3 of the California
Building Code. The coefficient of variation of subgrade reaction used in the deflection
calculations shall be provided from an approved geotechnical engineering report or
other approved methods.
(g) PA Effects. The requirements of the Building Code shall apply except as
modified herein. All framing elements not required by the design to be part of the lateral
force resisting system shall be investigated and shown to be adequate for vertical load
carrying capacity when displaced three times the displacements resulting from the
required lateral force. The stress analysis of cantilever columns shall use a buckling
factor of 2.1 for the direction normal to the axis of the beam.
(h) - Ties and Continuity. All parts of the structure included in the scope of
subsection (b) of this Section shall be interconnected and the connection shall be
capable of resisting the seismic force created by the parts being connected. Any smaller
portion of a building shall be tied to the remainder of the building with elements having a
minimum strength equal to one -fifth of the tributary dead load of the smaller portion. A
positive connection for resisting a horizontal force acting parallel to the member shall be
provided for each beam, girder or truss included in the lateral load path. This force shall
not be less than one -tenth of the combined tributary dead and live loads or as required
by the lateral load path transfer, whichever is greater.
- - (i) Collector Elements. Collector elements shall be provided that can
transfer the seismic forces originating in other portions of the building to the elements
129
within the scope of subsection (b) of this Section that provide resistance to those forces.
Q) Horizontal Diaphragms. The analysis of shear demand or capacity of an
existing plywood or diagonally sheathed horizontal diaphragm need not be investigated
unless the diaphragm is required to transfer lateral forces from the lateral resisting
elements above the diaphragm to other lateral resisting elements below the diaphragm
due to offset in placement of the elements.
Wood diaphragms in structures that support floors or roofs above shall not be
allowed to transmit lateral forces by rotation or cantilever. However, rotational effects
shall be accounted for when unsymmetric wall stiffness increases shear demands.
Exception: Diaphragms that cantilever twenty -five percent or less of the distance
between lines of lateral load resisting elements from which the diaphragm cantilevers
may transmit their shears by cantilever provided that rotational effects on shear walls
parallel and perpendicular to the load are accounted for.
(k) Shear Walls. Shear walls shall have sufficient strength and stiffness to
resist the tributary seismic loads and shall conform to the special requirements of this
Section.
(1) Gypsum or Plaster Products. Gypsum or plaster products shall not be
used to provide lateral resistance.
(m) Wood Structural Panels. Shear walls sheathed with wood structural
panels may be used to resist horizontal forces that do not exceed the allowable shear
values and story drift limitations of the Building Code.
Openings are permitted in shear walls if they do not exceed fifty percent of the
height or width of the shear wall. The remaining portion of the shear wall shall be
strengthened for the transfer and increase of all shearing forces caused by the opening.
130
The resulting shear wall shall be analyzed as a mosaic of shear resisting elements.
Blocking and steel strapping shall be employed at the corners of the opening to transfer
forces from discontinuous boundary elements into adjoining panel elements.
The effect of openings on the stiffness of the shear wall shall be demonstrated to
comply with the story drift limitations of the Building Code. The stiffness shall be
calculated using the properties of the different shear elements making up the shear wall
or it shall be demonstrated by approved testing. When shear walls cannot be made to
conform to the requirements of this Section because of existing openings, the openings
shall be relocated or reduced in width to meet the strength and stiffness requirements of
the lateral loads.
Relocated and altered openings shall comply with the emergency escape and
rescue requirements of the Building Code. Relocated and altered openings shall comply
with the light and ventilation requirements for residential occupancies unless otherwise
approved by the Building Officer.
(n) Wood Species of Framing Members. Allowable shear values for wood
structural panels shall consider the species of the framing members. When the
allowable shear values are based on douglas fir -larch framing members and framing
members are constructed of other species of lumber, the allowable shear values shall
be multiplied by the following factors: 0.82 for species with specific gravities greater
than or equal to 0.42 but less than 0.49, and 0.65 for species with specific gravities less
than 0.42. Redwood shall use 0.65 and hem fir shall use 0.82 unless otherwise
approved.
(o) Mechanical Penetrations. Mechanical penetrations in shear walls shall
be accounted for in the design or the shear wall shall be analyzed as two separate walls
131
on each side of the penetration.
(p) Substitution for Three -Inch Nominal Width Framing Members. Double
two -inch nominal width framing members shall be permitted in lieu of any required
three -inch nominal width framing member when the existing and new framing member
are of equal dimensions, are connected as required to transfer the in -plane shear
between them and the sheathing for the shear wall is equally fastened between them.
(q) Hold Down Connectors. Expansion anchors that provide tension
strength by friction resistance shall not be used to connect hold down devices to
existing concrete or masonry elements. Expansion anchors shall be permitted to
provide tension strength by bearing.
The required depth of embedment or edge distance for the anchor used in the
hold down connector shall be provided in the concrete or masonry below any plain
concrete slab unless satisfactory evidence is submitted to the Building Officer that
shows that the concrete slab and footings are of monolithic construction.
Bolted hold down connectors shall be pre - loaded to reduce slippage of the
connector. Pre - loading shall consist of tightening the nut on the tension anchor after the
- placement but before the tightening of the shear bolts in the panel flange member. The
tension anchor shall be tightened until the shear bolts are in firm contact with the edge
of the hole nearest the direction of the tension anchor. Hold down connectors with self-
jigging bolt standoffs shall be installed in a manner to permit pre - loading.
Deformation of hold down connectors at ultimate loads shall be compatible with
adjoining elements and shall be verified by approved testing.
132
SECTION 45. Section 8.72.090 of the Santa Monica Municipal Code is hereby
amended as follows:
8.72.090 Materials of construction.
(a) New Materials. All materials approved by the Building Code, including
their appropriate allowable stresses and minimum aspect ratios, shall be permitted to
meet the requirements of this Chapter.
(b) Allowable Foundation and Lateral Pressures. Allowable foundation and
lateral pressures shall be permitted to use the values from the Building Code. The
coefficient of variation of subgrade reaction shall be established by an approved
geotechnical engineering report or other approved methods when used in the deflection
calculations of embedded vertical elements as required in Section 8.72.080(f).
(c) Existing Materials. All existing materials shall be in sound condition and
constructed in conformance to the Building Code before they can be used to resist the
lateral loads prescribed in this Chapter. The verification of existing material conditions
and their conformance to these requirements, shall be made by physical observation
reports, material testing or record drawings as determined by the structural designer
and approved by the Building Officer.
..
............
(OM Wood Structural Panel Shear Walls.
(1) Allowable Nail Slip Values. When the required drift calculations of
133
Section 8.72.080(f) rely on the lower slip values for common nails or surfaced dry
lumber, their use in construction shall be verified by exposure. The use of box nails and
unseasoned lumber may be assumed without exposure. The verification of surfaced dry
lumber shall be by identification conforming to the Building Code.
(2) Reduction for Clipped Nail Heads. When exposed nails do not meet the
nominal head sizes required for hand driven nails in the Building Code, the allowable
shear capacity for shear walls sheathed with wood structural panels shall be reduced.
Allowable shear values for sheathing nailed with clipped nail heads shall be equal to
sheathing fastened with casing heads in the Building Code.
(3) Plywood Panel Construction. When verification of the existing plywood
materials is by use of record drawings alone, the panel construction for plywood shall be
assumed to be of three plies.
(4) Framing Members of Other Species. When verification of the existing
wood material is by use of record drawings, the allowable shear capacity shall be
multiplied by the reduction factor of 0.82 for buildings built on or after 1960. Buildings
built before this period shall use the reduction factor 0.65. When verification of the
existing wood material is by identification in conformance to the Building Code, the
allowable shear capacity in the Building Code may be used.
4gfe) Lumber. When the existing dimensioned lumber is not identified in
conformance to the Building Code, the allowable stresses for lumber shall be permitted
for the structural elements specified below.
Posts and beams
Joists and rafters
Studs, blocking
Douglas Fir -larch No. 1
Douglas Fir -larch No. 2
Hem Fir Stud.
134
(g_)M Structural Steel. All existing structural steel shall be permitted to use the
allowable stresses for Grade A36. Existing pipe or tube columns shall be assumed to be
of minimum wall thickness unless verified by testing or exposure.
(h)(gj Strength of Concrete. All existing concrete footings shall be permitted to
use the allowable stresses for plain concrete with a compressive strength of two
thousand psi. The strength of existing concrete with a record compressive strength
greater than two thousand psi shall be verified by testing, record drawings or records of
the enforcement agency.
()Q)A Existing Sill Plate Anchorage. Existing cast -in -place anchor bolts shall
be permitted to use the allowable service loads for bolts with proper embedment when
used for shear resistance to lateral loads and provided with plate washers as required in
the Building Code.
SECTION 46. Section 8.76.060 of the Santa Monica Municipal Code is hereby
amended as follows:
8.76.060 Time period for compliance.
(a) Engineering Report. Within two hundred seventy -five days of the date of
notice to the owner by the City, the owner of any welded steel frame structure shall
submit to the Building and Safety Department an engineering evaluation report
prepared by a California registered structural engineer based upon an inspection of a
representative sample of connections of the building ( "structural report").
The struGtural FepGFt shall indicate whether the steel frame StrUGt61Fe GGRfGFMS to
