Plan Review Checklist
Note on plans the edition of the I.R.C. code that will be used for review.
Verify soils report requirement per G.I.S. shrink/swell soils map and note on the cover sheet of approved plans if a soil report is attached. Soil scientist may perform soil test but P.E. is required to design footing, if required.
Verify if two copies of the roof truss and/or floor truss diagrams are attached.
Verify noted proffer conditions from the routed set of drawings and notes from the permit in Tidemark.
Verify lot line setbacks on the site plans (2 stamped copies required from the Permit Center). R302.1 If a building wall is within 5′-0″ of the property line, see special requirements under Non-Structural Items.
Verify if a zero lot line modification is attached to the plans and noted on plan cover sheet.
Footing and Foundation Review

Verify location of all bearing walls and match up with the foundation system.
Verify all joist and rafter spans using the floor span charts for room use above.
Verify sizing of all beams applying all loads from the structure above. It is recommended that manufacturer’s beam calculations be submitted for review.

Follow all point loads down to the foundation.
Verify deck attachment to the house band with the bolting chart and note that pressure treated bands and sills are required at the house attachment.
Review all roof truss diagrams for loads applied such as attic floor loads (finishable floor area versus attic storage), roof live loads (20-pounds/sq. ft.) and wind uplift loads.

Maximum fenestration U-factor of .35 (doors and windows) with one door and window exemption.
Maximum fenestration U-factor of .60 for skylights
Verify support of offset brick veneer per R703.7.2. Provide details of how offset brick veneer is supported when roof trusses are used and check roof truss for maximum deflection of l/600 when supported by wood framing.
Verify steel angle support of brick veneer attached to structural beams for the house frame. Deflection is limited to l/600.
Verify adequate roof ventilation.
If a basement is to be built, verify if it is considered a story above grade per the following definition of “story above grade”. When the finished surface of the floor above is:
1. More than 6′ above grade plane or
2. More than 6′ above grade plane for more than 50% of the total building perimeter or
3. More than 12′ above the finished ground level at any point.
Note: The building designer/applicant shall state on the plans when the basement is a “true” basement below grade and provide a basement wall section indicating this. (This condition may require the building plan review per the 2006 IBC code for 4-story buildings where there is a finished attic or the roofed-in area has headroom to be finished at a later date).
Verify that the openings shown on the floor plans and elevations are congruent.
Verify that exterior projections (bay windows, fireplaces, etc.) and exterior porches, stoops and decks are shown on the elevations.
Check that exterior finish materials (vinyl siding, brick, etc.) are clearly identified on the elevations.
Verify the roof slopes noted on the plans match the slopes indicated on the truss drawings or the roof framing shown in building or wall sections.
Determine if roof is framed with trusses or rafters and ceiling joists.
If trusses used, verify loads, including uplift design and attic floor loads.
Verify adequate bearing length is provided for trusses (assume SPF plates).
Verify adequate bracing details per BCSI-B3 or engineer design and correct layout plans are submitted with truss sheets.
Verify pitch shown on drawings match’s detail sheets.
If rafters used, verify grade, size, and species of rafters and ceiling joists
If a hip roof is used and it is more than 32 feet wide, ridges, hips, and valleys must be designed as beams with posts.
Verify spacing and span of rafters and check span tables for allowable spans
Check roof slope for compatibility with roof covering such as shingles.
Are ceiling joists nailed to the sides of the rafters? If they are not, either rafter ties 16″ o.c. or a ridge beam is required.
Ceiling joists nailed to the sides of rafters are allowed to be raised up to 1/3 of the height between the joist bearing and the ridge per notations from table R802.5.1.
Verify the ridge board depth is equal to or greater than the rafter cut.
In vaulted or cathedral ceilings, a ridge beam is required. All ridge beams require column support and joist hangers to tie rafters to the beam.
Special rules apply for Dutch or shed dormers.
Balanced hip roofs (less than 32′ house width) do not required beams and posts. Unbalanced hip roofs do. Complex unbalanced hip roofs usually require an engineer’s design and seal.
Roofs with less than 3:12 pitches require beam and column framing. Post loads must be supported by walls, posts, or framing below.
At roof openings for dormers, stairs, etc., design the full-length header and end rafters to support the actual applied loads.
Determine extent and use of attic to determine ceiling joist loads.
Verify depth of rafters is adequate for R-38/R-30 insulation.
Check second floor headers for loads from roof.
Verify ventilation provided.
Verify size and location of attic access (if required)
Wall Bracing (R602.10)
Identify the type of wall bracing to be used – Classic (R602.10) or Simplified (R602.12)..
Identify the type, location and length of all braced wall panels to be installed on all braced wall lines. (This is not required for continuously sheathed houses (CS-WSP) using the Classic Method). Also note on the floor plan if an A.P.A. design or other engineered design is specified at a particular location. Provide two copies of this design.
Provide wall bracing calculations if the Classic Method is used or if the Simplified Method is used.
Two-story BWP’s require design by a R.D.P.
Provide a wall section detail of all “stem walls” 48″ or less in length required by R602.10.9 on the foundation plan.
Roof framing may need to be blocked above braced wall panels per the options shown in R602.10.8.1, depending on how tall the roof framing height is at the braced wall panel location. Where roof heel heights exceed 48″ in height, the roof blocking needs to be designed by an R.D.P.
Miscellaneous Framing Items
Wall heights (studs) 10′ maximum per code.
Stud capacities – see table R602.3(5)
Required jack studs (2000 pounds maximum allowed per jack stud)

Verify bedroom egress window sizes per R310, particularly bedrooms located in within room trusses and basements.
Verify the garage/house gypsum separation requirements per R302.6.
If a building wall is within 5′-0 of the property line, check projection and opening limitations under R302.1. Also, check for a fire rated construction detail for all areas that are required to have protection.
For houses greater than 32 feet in width that contain a first floor, second floor, and habitable attic, the first floor exterior wall studs supporting the second floor and habitable attic must be 2×6 studs @ 16″ on center minimum. An R.D.P. stud calculation sheet can be provided if another stud size or spacing is desired to be used.
