• Mr. Dan King Plan Check Number: B2105-051, First Building Review November 3, 2021 inches per Section R803.2.3. Alternatively, a detail providing structural support for the sheathing should be included in the drawings. The framing should include adequate backspan and connections to supporting the framing. 10.The design appears to include a truss over the new north wall. Based on the proposed roof height, full height studs exceed the height limit permitted by the IRC. The studs are not continuous to the roof sheathing and will require out-of-plane bracing. This is typically provided by braces extending from the top plate to the roof sheathing. A detail should be provided. Note that the stability bracing per the truss manufacturer is not intended for this purpose. See Sections R106.1.1 and R301.1.3. 11.The foundation plan on Sheet 3 references IRC Table R403.1(1) for the footing construction. This is not sufficient. The required dimensions for the footings, including the walls supporting the wood-framed walls above, should be specified. See Section R106.1.1. 12.The foundation detail on Sheet 4 should specify a minimum 6-inch clearance for the wood framing above the adjacent grade. See Section R317.1 Item 5. 13.The proposed project includes modifications to the existing braced walls on each side of the 16- foot garage door. Cast-in-place anchors cannot be provided. Engineered post-installed anchors are required. The anchors are required to comply with the requirements of ACI 318-14 Sections 17.2.3.3 and 17.2.3.5.3. Alternatively, new foundations may be constructed on the west side of the existing building. See Section R301.1.3, and IBC Sections 1604.1 and 1901.5. 14.The foundation plan on Sheet 3 indicates that the actual available wall length south of the 16- foot garage door is 34.5 inches. The minimum required door width is 48 inches per Table R602.10.5 based on an adjacent opening and wall height of 96 inches. The garage door should be modified to provide the required opening. 15.The framing plans on Sheets 3 and 4 show the east end of Wall Line d as offset by approximately the wall thickness from the existing wall. The trusses above will similarly not align with the new wall per the roof framing plan, interrupting the installation of the wall sheathing provided the load path between the roof sheathing and the foundation below. The walls and trusses should be aligned. See Sections R106.1.1 and R301.1.3, and the following two comments. 16.The maximum dimension of the building at Wall Line D is 25 feet. A minimum of 2 braced panels are required per IRC Section R602.10.2.3. A panel is required at each end per Section R602.10.2.2.1. Based on the maximum clear height to the roof sheathing of approximately 12 feet, the minimum required wall length is 6 feet per Table R602.10.3(3). Note that the wall length will increase by at least 50% unless both sides are sheathed (i.e., minimum GWB required on the opposite side) per Table R602.10.3(4) Item 9. 17. Continuing with the previous comment, the minimum required braced wall at the east side of Wall Line D is required to be 6 feet. 3200 Cedar Street © 425.257.8810 AA, everetteps@everettwa.gov Everett,WA 98201 425.257.8857 fax everettwa.gov/permits Page 3 of 4
