Meeting Number 2: General Code Update
Instructor: Doug Oliver, Chief Building Official
County of Tuolumne
• Course Intent:
– To provide an overview of the significant
changes to the California Building Standards
– Identify new code provisions and State
amendments.
– Identify new legislation effecting local
construction.
• Course Outline:
– Building Code
– Plumbing Code
• New Legislation
–

Mechanical Code
Electrical Code
Energy Code
Green Building Standards
In order to make this quick…….
• Skipping the code sections.
• Skipping the minor stuff.
• Skipping the clarifications to stuff we
already know.
• Skipping the stuff that is not usually built
in this region
Building Code
• A ton of little changes.
• Several items removed and referenced to
other documents:
• Double Fire Walls allowed.
• Ten Year Lifespan on Smoke Detectors
Building Code
• Green Building Standards inserted and
referenced in the CBC.

Waste reduction
Storm water
Interior finish products (VOC)
Required mechanical ventilation in bathrooms
Green Building Standards now enforced on
additions/remodels.
Building Code
• Solar Power
– Panels on roof with no usable space not
counted as an addition story for maximum
height calculations.
– PV structures exempt from sprinklers if no
usable space underneath.
– All solar equipment on roof must now meet
general fire requirements (1505.1 or UL1703).
– Ballasted PV system design added to chapter
16
– SOLAR INSTALLERS: STUDY sec. 1505
through 1511.1.1
• For Engineers:
– Occupancy Category changed to Risk
Category.
– Strength design load combo’s have been
coordinated with Section 2.3 of ASCE 7-10 and
include fluids, other lateral pressures, and ice.
– Allowable Stress Design coordinated with
ASCE 7-10
– Table 1607.1 updated (minimum live loads)
– Wind speed and Seismic acceleration maps
updated.
– Seismic now references Risk Targeted
Maximum Considered Earthquake (MCEr)
Ground Motion Response Accelerations
More engineer fun
• Table 1607.1 revised
• Uninhabitable attic with storage in 1 and 2 family
now 20lb live load.
• Wind Loads now based on ASCE 7-10
• Wind Maps based on Ultimate Design Wind
Speed = Vult
• Substantial rewrites of Chapters 16 and 17
– See table 1705.2.2 and 1705.3
• Simplified design methods for single story
masonry buildings – TMS 403-10
• Table 1604.3 clarifies deflection limits for
structural members.
More more engineering fun
• Retaining and Foundation walls in Seismic
Design Categories D, E, and F exempt
from Geotechnical Report if supporting no
more than 6 feet of backfill.
• AISI S110 now referenced in the code for
Cold-Formed Steel Design.
• Rules Omission: 3x members at panel
edges for 2” nailing omitted from code and
Section 4.3.7.1 of SDPWS-08 (It didn’t
leave, it moved).
Egress
• Stairway provisions clarified to apply to
ALL stairways for occupied areas of the
building.
• Window Guards for dwellings = if over 72”
above grade and less that 36” above
finished floor, window opening max 4”
Accessibility
• Revised in its entirety
• 11A revised to incorporate language from
the new 11b and 2010 ADA
• 11B revised using same format as 2010
ADA.
• Change references:
– http://www.hcd.ca.gov/codes/shl/2013codeado
ptproj_part2.html.
– http://www.dgs.ca.gov/dsa/Programs/progAcc
ess/access2013/aspx
Interior Environment
• Attic Ventilation Clarified
– 1/150 or 1/300 if either
• Greater than 40% but less than 50% vent area in the
upper portion of attic
• Mechanical ventilation required in
bathrooms
Hazardous Locations (glazing)
• All the same material from last powerpoint
reproduced in the 2013 CBC.
• Copies available.
Water Resistive Barriers
Plumbing Changes
• Greywater Update
– Chapter 16 – HCD
– Chapter 16A - DWR
• Rainwater Catchment Systems
– Permit exemptions for drip irrigation less that
5,000 gal and not over 2/1 Height to Width
Ratio, or spray irrigation less than 360 gallons.
New Law #1
• For all additions, remodels, and new
structures. ALL plumbing fixtures must
be low-flow:
Toilets – 1.6 gal/flush
Urinals – 1 gallon/flush
shower heads – 2.5 gallons/minute
interior faucets – 2.2 gallons/minute
New Law#2 Contractors License Law
• Licensed Plumbers may now install
sprinkler systems

Starting January 2014
Only on one and two family dwellings
Only until January 2017
Only if they want to!
Electrical Code
• Existing building exemption to 6 ½ foot
working clearance. (200 amp or less)
• Posting identification means for branch
circuits in panel boards now required.
– Especially where different systems originate
• Exemptions to arc-fault circuit breakers
– Arc-fault outlet protecting circuit allowed if
using RMC, IMC, EMT, Type MC or AC and
first box is metal and bonded.
– Also allow if Metal conduit buried in 2 inches
if concrete.
GFI clarification
• Exemptions for dedicated snow
melting/deicing circuits
• (dwelling units)Within 6 ft of sinks,
located in areas other than the kitchen.
• (other than dwelling units)
– Indoor wet locations
– Locker rooms w/associated show facilites
– Garages, service bays, and similar uses where
diagnostic equipment, electrical tools, or
portable lighting are to be used
Countertop clarification
• Kitchen sink divides countertop into
separate spaces if closer than 12” to wall
– 18” for corner sinks
– Counts for peninsula and island sink. Measure
amount of counter space behind sink.
– Includes permanently installed ranges and
cooking units.
Electrical fun-facts
• Bathroom and kitchen outlets can be
installed in the counter top if listed for the
purpose.
• If any accessory building is provided with
electrical power, at least one receptacle is
required. (yes, it must be GFI and 18”
above the floor)
• All raceways entering a building from an
underground distribution system must be
sealed, whether or not they are used.
For electricians:
• Study 2013 Electrical Code sections 225.52
“disconnecting means” and 56 Inspections
and tests – a lot of text differences in this
area.
• On anything bigger than a house, please
have all test reports available for the
Building Inspector at the appropriate
inspection.
Back to the fun facts:
• 3 ft roof top clearance reduction for service
drops now allowed on “isolated” or
“guarded” rooftops.
• If service disconnecting means exceeds six
locations for multi-occupancy buildings,
Suitable graphics, on placards, are required
to be placed within sight of the equipment
showing the locations of all disconnects.
– Study 230.2, 40, 71, and 72 understand service
conductors vs. service entrance conductors.
Warning!
• Article 250 has many clarifications and
language changes. To much for today's
training. To much for a 2 hour class. Seek a
trained trainer! Or wait for me to figure it
out and provide training! (see you in 3
years)
Electrical summary
• We covered less than 10% of the little
tweeks to the electrical code. Many
changes do not effect 90% of the
construction in this County. At the same
time, this is one of the most important
codes to understand. Expect growing
pains on this, I encourage debate!
Energy Code
• Hers Rater is required to be employed on
all projects over 300 square feet.
– Required on less than 300 square feet if
replacing HVAC or over 40 ft of ducting.
• All documents must be registered with the
State.
• Many of the trade-offs from the previous
code cycle are now mandatory measures.
GOOD NEWS EVERYONE! Energy
Code Enforcement is delayed to July 1,
2014. Applies to parts of Calgreen as
well
