• Mr. Garin Schenk Architecture Studio of Everett Plan Check Number: B2110-017, First Building Review November 8, 2021 General 1. The drawings should clearly delineate between existing and new work using established drafting standards. A legend should be included for wall construction. See Section R106.1.1. 2. The Bedroom in the southwest corner of the building appears to be two rooms. Verify if a wall is missing. See Section R106.1.1. Architectural 1. The"Ventilation Notes"on Sheet A2.2 provide calculations for the venting of the new addition roofs. See Section R806.2. The following comments should be addressed: a. The calculation appears intended to address the additions only. Note that the 800 SF area used is not clear; the additions have an estimated total area of 593 SF per Sheet A1.0. The additions are anticipated to impact the ventilation for the existing building. Details providing ventilation through the existing roof should be included. b. The calculation is based on a ratio of 1/300. The building does not qualify for the exceptions. A ratio of 1/150 should be used, doubling the required area. 2. Attic access should be provided for the north addition per Section R807. 3. The crawl space under each addition is required to provide an access opening with a minimum size of 16 inches by 24 inches. See Section R408.4. 4. Smoke and CO alarms should be provided per Sections R314 and R315. The locations of all alarms should be shown on the plans. A note should be included requiring the alarms to be hardwired, interconnected, and provided with back-up battery power as required. Alarm clearances should comply with Section R314.3 Item 4 and Section R314.3.1. 5. The should specify an exhaust fan including the minimum required performance rates per Table M1505.4.4(1). 6. Detail 6/A4.0 appears to provide a 1-inch air gap. The detail should clearly specify an eave baffle extending above the insulation. See WSEC Section R402.2.3. Structural 1. A general fastener schedule should be provided per Table R602.3(1). Providing a reference to this table in the drawings does not satisfy this requirement. In addition, the make and model of proprietary hardware should be specified where used for connections. 2. The wood joists and ledgers in Sections 1/A4.0 though 3/A4.0 appear to be located less than 18 inches above the grade below. The minimum clearance should be provided, or preservative- treated lumber should be specified.
