Mr. Dave Marlow Integrity Custom Builders LLC Plan Check Number: B2107-048, First Building Review August 12, 2021 General 1. The architectural and structural general notes on Sheets 4 and S-1.0, respectively, reference the 2015 versions of the building codes. The proposed project should comply with the requirements of the 2018 editions of the IRC and IBC. The drawings should be revised as needed to comply with the current code requirements. See Section R106.1.1 and EMC Section 16.005.030. 2. The project includes a site plan that does not clearly show the proposed location of the building on the lot. The plan should be revised. Fire separation distances (FSD) with the lot lines and the existing single-family residence (SFR) should be specified. An imaginary lot between the existing and new buildings should be shown. Note that the Planning department has also issued comments on this issue; see the Planning correction letter emailed on 08/05/2010 for additional information. See Section R106.2 and additional comments below. Architectural 1. The building appears to be located with FSD to the property lines of less than 2 feet. See Table 302.1(1). The following comments should be addressed: a. The building is required to have fire-rated walls on the north and west sides. Details providing listed tested assemblies should be included in the construction drawings. The details should include the assembling listing number. b. Openings in the exterior walls are not permitted on the north and west sides. The windows should be removed. Note that the closet window shown in the Floor Plan on Sheet 1 is not shown in the Rear Elevation. c. Continuing with the previous comment, roof ventilation openings are similarly not permitted along the west eave. See additional comments below. d. Eaves (i.e., projections) are not permitted along the north and west sides. Note that if the FSD to the roof eave exceeds 2 feet but is less than 5 feet, fire-rated construction is required. e. Continuing with the previous comment, the eave and rake dimensions should be specified in the construction plans for all sides of the building. 2. The building is understood to be located within the minimum lot setbacks and may required relocation by the Planning department. Depending on the revised location, the building may be subject to additional fire-rated construction requirements along the south and east walls due to FSD with the existing SFR. An additional permit to modify this structure may be required to modify the existing SFR is adequate FSD are not maintained. See Table R302.1(1). 3. The FSD distance does not permit installation of ventilation openings along the north and west sides, preventing adequate distribution of ventilation openings at the building perimeter. The roof system should be revised to be an unvented roof.
