Standard Codes Schedule
Subject to the amendments and exceptions indicated, each of the codes mentioned in this Schedule, including all
of its published appendices and attachments ("Standard Codes'), is adopted, ordained and made a part of the
Code of Ordinances and of each chapter where it is referenced. If two or more ordinance provisions apply in
any given circumstance, they shall all be given effect if possible, but if not, the provision imposing the highest
standard controls.
LOCAL AMENDMENTS (ALL CODES). The following local amendments control over all Standard Codes:
1. ADMINISTRATION. Chapter 6 of the Code of Ordinances governs administration. The chief administrative officer and the issuing
official for all permits is the building official(except under the fire code,where it is the Fire Chief). The BSC has the same jurisdiction
and authority with respect to each Standard Code as it has with respect to the building code,including appeals,quasijudicial enforcement,
variances and opinions.
2. ARCHITECT. Plans and specifications,signed and sealed by an architect legally registered under state law,are required for:(i)each
building project(either new construction or remodeling involving structural alterations)with a value more than$100,000,and(ii)other
projects specifically mentioned in the Standard Codes(see,e.g.,SBC Sec. 104.2.3).
3. ENGINEERED FOUNDATIONS. New building foundations and foundation repairs must be designed by a registered professional
engineer("RPE"),and the work shall be:
a. illustrated in complete plans and specifications signed and sealed by the RPE;
b. based on a soils report from a recognized and reputable firm or agency(Exception:no soils report is required for a single-story
accessory building with less than 450 sq.ft.of gross floor area);and
c. inspected by an RPE who certifies proper construction,before work proceeds further.
4. CONCRETE.
a. Driveways,sidewalks and other concrete flatwork everywhere must meet or exceed the applicable specifications for similar work
done in street areas(See,e.g.,Chapter 19 and City standard specifications.)
b. Reinforcing steel bars or mats must be used. Wire mesh may be used as additional reinforcement,if securely fastened to a rebar
mat.
c. All concrete footings and foundations must be cured for at least 72 hours before any significant load is placed on them.
Exception:This does not apply if an RPE certifies that the concrete is sufficiently cured.
5. ENGINEERED STRUCTURAL DESIGN. Plans and specifications,signed and sealed by an RPE who certifies compliance with the
applicable structural design criteria(e.g.,SBC Sec. 1606, 1&2FDC Sec.301),are required for all new building space. Before any framing
is concealed,it must be examined and certified by an RPE as complying with those design criteria and the approved plans and
specifications.
6. RESIDENTIAL STANDARDS. The following standards apply to all new building space(new construction and additions)intended
primarily for residential use. The standards apply to existing building space only as specifically indicated.
a. Foundation Design. The foundation must:(i)use a pier-and-beam(with crawl space)or structural slab(voided slab)design,(ii)
minimize contact between foundation and soil,and(iii)conform to sound,recognized engineering practices applied in areas with
similar geotechnical conditions. Exception:does not apply to a single-story accessory building with less than 450 sq.ft.of gross
floor area.
b. Certain Separations. A 4-hour-fire-resistance-rated assembly must separate attached dwelling units. Garage space must be
separated from other occupancies by a 1-hour-fire-resistance-rated assembly,or by 73 inches(horizontal separation,wall to
wall).
c. Drainage. Site drainage systems approved under Chapter 6 control over Standard Code provisions to the contrary.
d. Framing Wood. All structural wood framing materials shall be#2 Grade or better. All wood studs must 100%Douglas Fir
without finger joints. Exception:These requirements do not apply to non-structural uses such as blocking,deadwood,furr
downs,etc.
e. Floor Decking. All wooden floor decking shall be:(1)made of 1-1/8-inch T&G plywood or better,with any voids filled in all
plies(e.g.,"Sturdi-floor"or equal),except for areas to receive concrete,tile,masonry or similar finishes,which must be decked
with CCA treated 3/4-inch plywood or better;(2)constructed with blocked edges,and(3)glued and screwed to all joists and
blocking,with screw spacing no more than 8 inches OC. Example:oriented strand board and similar materials("OSB")are
forbidden.
f. Sheathing. All exterior sheathing must:(1)be 1/2-inch CDX plywood or better,(2)have a rot resistance equal to or better than
CCA treated plywood,if within 48-inches of finished grade,and(3)not be attached with staples. Example:OSB sheathings are
forbidden.
g. Wall Connection. Walls on upper floors shall be substantially connected to the walls below by one or more of the following
methods:(1)overlapping the sheathing from the upper to the lower wall,so that at least three feet of each sheet is attached to
each one,(2)using galvanized or better metal connections from the upper to the lower wall,or(3)equal or better methods. _
h. Roof Decking. Wooden roof decking must:(1)be 1/2-inch plywood or better,and(2)not be attached with staples. Example:
OSB decking is forbidden.
i. Rafter Ties. For conventional wood-framed roofs,Simpson H-4(or better)rafter ties are required on every other rafter.
j. Roof Coverings. All roofs must have coverings with Class C or better fire resistance determined under the SBC.
k. Exterior Wood Trim. Painted exterior wood trim must:(1)be#1 Grade or better,(2)have a rot resistance equal to or better than
CCA treated pine,and(3)not have finger joints,unless specifically designated for exterior use by the manufacturer. Exception:

Sec.6.401
Subject to the amendments and deletions indicated in the Standard Codes Schedule,each of the following codes listed in the Standard Codes
Schedule,including all of its published appendices and attachments,is adopted,ordained and made a part of the Code of Ordinances of the City

the City,except in compliance with the adopted or electrical
