William Velasco Plan Check Number: B2202-028, Second Building Review May 10, 2022 Architectural 1. The project involves increasing the conditioned space at the basement level. Energy credits are required per WSEC Section R406. The required number of credits should be normalized per Table R406.2. A schedule of the selected credits should be included in the drawings. The performance requirements for the selected credits should be specified. 2. Continuing with the previous comment, the basement level walls should be updated to comply with the 2018 WSEC. Below grade walls should be insulated per Table R402.1.1 unless modifications are required per selected energy credits. A detail of the basement level walls should be provided on the drawings. 3. See Basement Floor Plan on Sheet 4. Address the following: a. Window wells with a vertical depth greater than 44 inches should be equipped with a permanently affixed ladder or steps. R310.2.3.1 b. The window well should be provided with drainage as specified in Section R310.2.3.2. Structural 1. The modified load paths should comply with the prescriptive limitations of the IRC. Alternatively, an engineered analysis and design may be performed per IRC Section R301.1.3; sealed and signed drawings and calculations prepared by a professional engineer licensed in the state of Washington are required per RCW 18.43.010, 18.43.020, and 18.43.070. The framing and foundation plans, and structural calculations as required, should show a complete load path. See IRC Section R301.1. 2. Continuing with the previous comment, the proposed project includes the demolition of existing walls. Framing plans for the floor, ceiling, and roof should be provided to substantiate that the walls are not load-bearing. The plans should also include a note requiring the contractor to verify the walls are not load bearing prior to demolition. Plans should show a complete load path. See IRC Section R301.1. 3. See Main Floor Framing Plan on Sheet 5. Plans should be updated to reflect existing conditions or show new framing where existing is being modified. Drawings should be updated to show the existing supports for the existing beams located in the basement. The framing plan shows 2-2x10 existing beams spanning about 25 feet; however, pictures available on the real-estate website Redfin.com show that the existing beams are supported by posts and significantly reducing the span. The beam does not meet the prescriptive limitations of the IRC if the supports are removed and should be updated. See structural comment 1 for more information. 4. See Floor Framing Plan on Sheet 5. Plans should show the framing requirements of infilling the existing stair removal. Plans currently show existing floor joists spanning around 25 feet. These joists do not meet the prescriptive tables of the IRC and should be updated as required. See comment 3 for more information. 3200 Cedar Street G) 425.257.8810 O everetteps@everettwa.gov Everett,WA 98201 425.257.8857 fax everettwa.gov/permits Page 2 of 3
