CALIFORNIA BUILDING CODES, WITH LOCAL
AMENDMENTS AND CREATING TWO NEW TITLES IN THE

DEPARTMENT: Public Works
RECOMMENDED ACTION
City Council introduce and pass to second reading an ordinance entitled "AN ORDINANCE OF
THE CITY COUNCIL OF THE CITY OF SANTA CLARITA, CALIFORNIA, REPEALING
AND REPLACING TITLES 18 THROUGH 22 OF THE SANTA CLARITA MUNICIPAL
CODE AND ADDING TWO NEW TITLES TO THE SANTA CLARITA MUNICIPAL CODE,
TITLE 24 CITY ENERGY CONSERVATION CODE AND TITLE 25 CITY GREEN
BUILDING STANDARDS CODE, AND ADOPTING BY REFERENCE THE 2010
CALIFORNIA BUILDING, RESIDENTIAL, ELECTRICAL, MECHANICAL, PLUMBING,
ENERGY, FIRE, AND GREEN BUILDING STANDARDS CODES WITH CERTAIN
APPENDICES AND AMENDMENTS," and set the public hearing for November 23, 2010.
BACKGROUND
The State of California (State) mandates that local jurisdictions adopt and commence
enforcement of the updated State building codes, comprising Title 24 of the Code of Regulations,
every three years. The City has complied with this State mandate and has been enforcing the
State building codes since incorporation in 1987.
The State codes are approved and published under the direction of the California Building
Standards Commission and are intended to provide for the safety and welfare of all citizens
Ordinance passed toi.
Second reading
through the implementation of the latest technology, materials, engineering, and construction
methods, as regulated by the latest adopted building codes.
The California Building Standards Commission recently updated the California Building Code,
Electrical Code, Mechanical Code, Plumbing Code, Energy Code, and Fire Code, while also
introducing two entirely new State codes, the Residential Code and the Green Building Standards
Code, setting an effective date of January 1, 2011, for enforcement by local building departments
throughout California.
This ordinance adopts the above referenced 2010 California codes, along with local amendments,
and also adds two new titles, Title 24 and Title 25, in the Santa Clarita Municipal Code, creating
a new City Energy Conservation Code and new City Green Building Standards Code. Creating
these new titles is consistent with the format of the Municipal Code and provides a separate
location in the Santa Clarita Municipal Code for each of these State codes.
Title 24, City Energy Conservation Code, ensures all new buildings, additions, alterations, or
HVAC equipment upgrades comply with the latest State mandates for energy efficiency, thereby
reducing energy consumption and associated energy costs to property owners. Title 25, City
Green Building Standards Code, ensures new buildings are designed and constructed in a manner
that reduces any negative impact the building may have on the environment while encouraging
resource conservation during construction and throughout the life of the building.
State law allows local jurisdictions to further amend the State building codes, where necessary, in
accordance with the provisions of the State Health and Safety Code, in order to address adverse
local conditions related to climate, geology, and/or topography. The proposed City amendments
included in this ordinance provide for higher standards for fire and earthquake protection for
buildings constructed throughout the City. The amendments also set forth administrative
provisions providing for enforcement, collection of fees, and clarifying work that is exempt from
permits, all of which are consistent with the City's current practices and adopted amendments.
The ordinance does not include any new fees nor does it modify any fee currently adopted by the
City Council. The ordinance establishes an effective date of January 1, 2011, as mandated by the
State.
As part of an outreach effort to involve the local development community in the amendment
process, contractors, design professionals, developers, and the local Building Industry
Association (BIA) chapter were invited to a public meeting at City Hall to review the proposed
local amendments to the codes. During the meeting, the public had an opportunity to provide
valuable input regarding the proposed amendments. The information was well received with no
significant opposition. Additionally, a series of public workshops are scheduled for later this year
at City Hall to further explain the upcoming code adoptions and City amendments to contractors,
designers, engineers, and other members of the community.
In accordance with the California Government Code, public notice will be duly given and a copy
of the proposed codes and amendments is available for public viewing in the City Clerk's office
prior to the public hearing.
N
ALTERNATIVE ACTIONS
No alternative actions are identified at this time.
FISCAL IMPACT
Some increase in staff resources may become necessary to adequately enforce the additional
regulations included in the new State codes. In particular, enforcement of the new Green
Building Standards Code may create a demand for additional staff time from Planning, Building
and Safety, Environmental Services, and Development Services in the plan review and field
inspection process to ensure adequate levels of compliance with the new provisions.
The impact of enforcement of the new codes will be monitored and evaluated during the current
fiscal year to determine if additional fees would be appropriate to be collected for applicable
projects, as permitted by State law, to pay for increased enforcement costs incurred by the City.
These factors should be evaluated further during the next budget process to better determine any
staffing or financial implications as a result of the new State codes.

in effect until the Building Official records in the Department of Registrar -Recorder a
statement that he finds such hazard no longer exists.
d. When the work involves the alteration or minor repair of existing structures and the cost
of such alteration or repair does not exceed 25 percent of the value of the existing
structure, such value to be based on assumed continuation of the established legal use.
Before a permit is issued, the owner shall record in the office of the Department of
Registrar -Recorder (1) a statement that he is aware that the records of the building
official indicate that the property is subject to a physical hazard of a geological nature
and (2) an agreement relieving the City and all officers and employees thereof of any
ability for any damage or loss which may result from issuance of such a permit. This
agreement shall provide that it is binding on all successors in interest of the owner and
shall continue in effect until the Building Official records in the office of the Department
of Registrar -Recorder a statement that he finds such hazard no longer exists. The repair
work shall consist of restoring the original construction. Provision may be made for
adjustment of the floor in anticipation of future settlement. For the purposes of this
subsection "alteration" does not include an addition or additions.
e. When the work involves an addition or additions to an existing structure but is not a

more than 25 percent of the area of the structure. Before a permit is issued, the applicant
shall submit a geological and/or engineering report or reports complying with the
Page 12 of 58 %
provisions of subsection (f) of this section which report or reports contain a finding that
the proposed increased use of the site will not be geologically unsafe, and the owner shall
record in the office of the Department of Registrar -Recorder (1) the finding of such report
or reports and (2) an agreement relieving the City and all officers and employees thereof
of any liability for any damage or loss which may result from the issuance of such a
permit. This agreement shall provide that it is binding on all successors in interest of the
owner and shall continue in effect until the Building Official records in the office of the
Department of Registrar -Recorder a statement that he finds a hazard no longer exists.
f. When the work involves a one-story, light -frame accessory structure not intended or used
for human occupancy and not exceeding four hundred (400) square feet in area nor
greater than 12 feet in height.
When the work involves the repair of single-family residences and accessory buildings
where the cost of such repair exceeds 25 percent of the value of the existing building or
involves the replacement of such structures where the loss to be replaced was due to
causes other than landslide, settlement or slippage. Before a permit is issued the owner
shall:
1) Record in the office of the Department of Registrar -Recorder (1) a statement that he
is the owner and that he is aware that the records of the Building Official indicate
that the property is subject to a physical hazard of a geological nature and (2) an
agreement relieving the City and all officers and employees thereof of any liability
for any damage or loss which may result from issuance of such a permit. This
agreement shall provide that it is binding on all successors in interest of the owner
and shall continue in effect until the Building Official records in the office of the
Department of Registrar -Recorder a statement that he finds such hazard no longer
exists.
2) Submit calculations and plans for the proposed reconstruction prepared by a
registered civil engineer and designed to minimize damage while accommodating the
amount of vertical and horizontal displacements which he determines are probable or
which have occurred since the original structure was built, whichever is the greater.
g. Notwithstanding any other provisions of this subsection, the Building Official may, at his
discretion, deny a permit for any building, structure or grading subject to a hazard of a
geological nature which cannot be mitigated and may endanger the health or safety of the
occupants, adjoining property, or the public.
117.3 Fills Containing Decomposable Material. Permits shall not be issued for buildings or
structures regulated by this code within 1,000 feet of fills containing rubbish or other decomposable
material unless the fill is isolated by approved natural or man-made protective systems or unless
designed according to the recommendation contained in a report prepared by a licensed civil engineer.
Such report shall contain a description of the investigation, study and recommendation to minimize
the possible intrusion, and to prevent the accumulation of explosive concentrations of decomposition
gases within or under enclosed portions of such building or structure. At the time of the final
inspection, the civil engineer shall furnish a signed statement attesting that the building or structure
has been constructed in accordance with his recommendations to decomposition gases required herein.
117.4 Conditional Use. Work required by this section as a condition for the use of the.site shall be
performed prior to the connection of the utilities or occupancy of the building.
117.5 Methane Gas Hazard Sites. Permits shall not be issued for buildings or structures regulated
by this code on, adjacent to, or within 200 feet of active, abandoned or idle oil or gas well(s) unless
designed according to recommendations contained in a report prepared by a licensed civil engineer

and approved by the Building Official. As used in this section, "well' shall mean any well as defined
by Section 3008, subdivisions (a) and (b) of the California Public Resources Code.
117.6 Geology and Engineering Reports. The Building Official may require an engineering geology
or geotechnical engineering report, or both, where in his opinion such reports are essential for the
evaluation of the safety of the site. The engineering geology or geotechnical engineeringreport or
both shall contain a finding regarding the safety of the building site for the proposed structure against
hazard from landslide, settlement, or slippage and a finding regarding the effect that the proposed
building or grading construction will have on the geologic stability of the property in question and
properties immediately adjacent. Any engineering geology report shall be prepared by a certified
engineering geologist licensed by the State of California. Any geotechnical engineering report shall be
prepared by a civil engineer qualified to perform this work, such as a geotechnical engineer
experienced in soil mechanics. When both an engineering geology and geotechnical engineering
report are required for the evaluation of the safety of a building site, the two reports shall be
coordinated before submission to the Building Official.
117.7 Earthquake Faults.
1. General. The construction of a building or structure near a known active earthquake fault and
regulated by this code shall be permitted as set forth in this section.
2. Scope. The provisions of this section shall apply only to permits for buildings or structures on
individual lots or parcels and are not intended to be supplementary to geologic investigations
required to qualify divisions of land as set forth in the Uniform Development Code of the City of
Santa Clarita.
3. Definition. For the purpose of this section, a "geologist" shall be a registered geologist, licensed
by the California State Board of Registration for Geologists and Geophysicists to practice geology
in California.
4. Known Active Earthquake Faults. For the purpose of this section, known active earthquake
faults are those faults which have had displacement within Holocene time (approximately the last
11,000 years) as defined in the most current issue of Special Publication 42 of the California
Division of Mines and Geology.
5. Earthquake Fault Maps. Special studies zone maps within the City of Santa Clarita prepared
under Sections 2622 and 2623 of the California Resources Code which show traces of earthquake
faults are declared to be, on the date of official issues, a part of this code. Special studies zones
maps revised under the above sections of the California Resources Code shall, on the date of their
official issue, supersede previously issued maps. Copies of each of the above maps shall be
available for examination by the public at the City. The City shall maintain maps available to the
public showing the location of known active earthquake faults. In the absence of additional
information, the location of known active earthquake faults shall be as shown on special studies
zones maps.
6. Construction Limitations. No building or structure shall be constructed over or upon the trace of
a known active earthquake fault in the following cases:
a. When the proposed building is within 50 feet of that line designated as the location of a
known active earthquake fault on the aforementioned maps.
b. When the proposed building is within 50 feet of the most probable ground location of the
trace of a known active earthquake fault shown on the aforementioned maps.
In cases when a geologist has not made such a determination, the City may require the excavation
of a trench, as a subsurface exploration for the purpose of determining the absence of a known
active earthquake fault. Such a trench will be required if a lack of distinguishable fault features in
the vicinity prevents the City from determining by a site examination, review of available aerial
photographs, or by other means that the fault trace does not underlie the proposed building. The
Page 14 of 58
trench shall be approximately perpendicular to the most probable direction of the fault trace, at
least 18 inches wide, and at least five feet in depth measured from natural grade, or to a depth
satisfactory to the City.
The trench must be accessible for mapping and inspection by the City, when requested, and meet
the requirements of Title 8 of the California Code of Regulations, Construction Safety Orders.
The trench need not extend further than the full width of the proposed structure plus five feet
beyond the traversed exterior walls. A known active earthquake fault shall be presumed
nonexistent if an exposure is not found in the walls or floor of the trench. The City may require a
more extensive investigation by a geologist as evidence to the absence of a known active
earthquake fault prior to the issuance of a building permit.
EXCEPTION: The provisions of this subsection do not apply to:
1. One-story, light -frame buildings classified as R-3 and U occupancies and not exceeding 1,000
square feet in area or 12 feet in height.
2. Alterations or repairs to an existing building provided that the aggregate value of such work
within any 12 month period does not exceed 50 percent of the value of the existing building.
3. Swimming pools, retaining walls, fences and minor work of a similar nature.
Special Studies Zones. Work within the special studies zones established under Sections 2622 and 2623 of the
California Public Resources Code shall comply with State laws, policies, criteria, rules and regulations
applicable to such work. Fees established by Chapter 7.5 of Division 2 of the California Public Resources Code
shall be collected and disbursed as required by State law. In addition to the State regulations, the provisions of
this section shall apply when geologic investigations, mapping, aerial photographs, other acceptable data or
Special Studies Zones Maps show the location of a known active earthquake fault as described in this
subsection.

1613.12 Seismic Design Provisions for Hillside Buildings.
1613.12.1 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%). These regulations
establish minimum standards for seismic force resistance to reduce the risk of injury or loss of life in
the event of earthquakes.
1613.12.2 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 division.
Exception: Non -habitable accessory buildings and decks not supporting or supported from the
main building are exempt from these regulations.
1613.12.3 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.
Page 19 of 58
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 perpendicular to
the slope contours.
FOUNDATION is concrete or masonry which 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%). 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 1613.12.5 and 1613.12.7.3 between the diaphragm and the uphill foundation.
SECONDARY ANCHORS are diaphragm anchors designed for and providing a redundant
diaphragm to foundation connection, as described in Sections 1613.12.6 and 1613.12.7.4.
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.
