Twelve Things You Must Know!!
1. WAC Amendment Table R302.1 Fire Resistant Construction for Exterior Walls — Eave or other projections
for walls less than 5 feet from property lines require one hour fire protection on the underside unless fire
blocking is provided at the wall or no gable end vent is installed. This effectively eliminates any venting at
the exterior wall if within 5 feet of the property line without fire protection.
2. R319.1 Address Numbers— Buildings shall have approved address numbers consisting of a minimum 4
inches high and a minimum stroke width of/: inch plainly legible and visible from the street.
3. WAC Amendment R327.1 Protection Against Radon — State adoption of IRC Appendix F for mitigation
measures applicable for buildings constructed in "High Radon Potential Counties" (Spokane County).
Appendix F Section AF101.1 (WAC Amendment) no longer permits un -vented (conditioned) crawl spaces.
Appendix F further requires passive radon vents to be installed in vented crawl spaces. WAC Amendment to
R408.2 permits 1:300 sq/ft ratios for ventilating crawl spaces.
4. Table R404.1.2(1) Minimum Horizontal Reinforcement for Concrete Basement Walls - Horizontal
reinforcement in all below ground stem walls is required with a minimum of (1) #4 rebar within 12 inches of
the top of the wall and (1) #4 rebar near mid height if less than 8 feet, and (1) #4 rebar within 12 inches of
the top of the wall and (1) #4 rebar at 1/3 points if more than 8 feet. Minimum vertical reinforcement is
listed in Table R404.1.2(8).
S. R502.2.2.3 Deck Lateral Load Connection — Hold-down tension devices shall be installed in not less than two
locations per deck, and each device shall have and allowable stress design capacity of not less than 1500
pounds.
6. R506.2.3 Vapor Retarder—A 6 mil polyethylene or approved vapor retarder with joints lapped not less than
6 inches shall be placed between the concrete floor slab and the base course or the prepared subgrade
where no base course exists. Exception is detached garages and other unheated accessory structures.
7. R602.10.8 Braced Wall Panel Joints —All vertical joints shall occur over and be fastened to common studs.
Horizontal joints shall occur over and be fastened to common blocking of a minimum 1 y: inch thickness.
Exception omits blocking if twice the required minimum length of braced wall panels are provided.
S. R602.10.9 Cripple Wall Bracing— Cripple walls shall be braced with a type and length of bracing as required
for the wall above multiplied by a factor of 1.15 and decreasing the distance between brace wall panels to
18 feet instead of 25 ft.
9. R612.2 Window Sills— Window fall prevention protection similar to guardrails (4 inch diameter sphere) is
required for operable portions of windows less than 24 inches above the finished floor, and greater than 72
inches above the adjacent exterior grade or surface below.
30. R702.4.2 Tile Backer Board —Section requires cement, fiber -cement, or glass mat gypsum backers for tile
installation in tub and shower areas and wall panels in shower areas.
11. R703.2 and Table R703.4— Water Resistive Barrier— Felt, or other approved barrier (house wrap) is
required over all exterior wall studs or sheathing, and there is no longer an exception for not requiring such
felt/barrier under panel sidings with shiplap joints.
12. Washington State Energy Code Section 505.2 Exterior Lighting- Luminaires providing outdoor lighting and
permanently mounted to a residential building or to other buildings on the same lot shall be high efficacy
(compact florescent with pin style base or similar efficient light source) lamps. Exception allows
incandescent fixtures controlled by motion sensors with integral photo sensors.

Check with the jurisdiction to determine if they accept electronic submittal of completed Prescriptive
or Component Performance forms
0 Check with thejurisdiction to determine what Outdoor Temperature is acceptable for the
purpose of sizing equipment
0 All jurisdictions will accept forms from a third party reviewer. Initially most jurisdictions will
spot check submitted forms to assure that current code values are being properly applied.
0 Blank duct testing affidavits and Compliance Certificates will be provided by each
jurisdiction in the residential permit packet materials.
3� All jurisdictions will require a copy of the completed Compliance Certificate at the time of

Residential Inspection Process
Duct Leakage Testing:
3;1, Duct testing must be completed and the completed affidavit provided to the inspector
before approval to "cover"will be issued. Testing at mechanical rough-in is highly recommended but in

installed. Results must be recorded on Compliance Certificate
f Duct testing affidavit must be prepared bya certified individual
j�& The WSEC has some exceptions to the requirement for duct testing. See WSEC section 503.10
ft Conditioned air ducts may not be installed in the exterior building envelope
i�t Building cavities may not be used as conditioned air ducts
a Environmental ducts may displace the minimum amount of insulation required to extend the duct to the
exterior of the building envelope as required by code
Building Air Leakage Testing:
f Blower door testing must be completed and results recorded on the Compliance Certificate
no later than the time of final and prior to issuance of a Certificate of Occupancy.
f Jurisdictions will conduct some spot checking of blower door tests. Builders will be notified
initially at the time of permit issuance, and as time progresses, randomly by the
inspector during the construction process if a required blower door test for a permitted
residential structure !s to be witnessed byjurisdiction staff.
3:E Be especially aware of sealing around tub/shower traps
3�- Important!!! The Building Air Leakage test must pass with the code specified rate -there are no excep-
tions or remedies in the WSEC!!!
Interior Lighting:
F A minimum of 50% of all luminaries shall be"high efficacy luminaries"as defined in the WSEC, Examples of
"high efficacy luminaries" Include: pin based compact fluorescent bulbs (CFL), LED. Linear fluorescent fixtures
