Mr. Larry Rouch Skotdal Real Estate Plan Check Number: B2211-084, First Building Review January 18, 2023 Architectural General: 1. The proposed project is located in a building with more than four dwelling units. The construction drawings are required to be sealed and signed by a professional architect licensed in the state of Washington. See RCW 18.08.410 Item 5. 2. The Occupancy Classifications for the building should be specified in the construction drawings. See IBC Section 302.1. 3. The Construction Types for the building should be specified in the construction drawings. See IBC Section 602.1. Fire Protection: 4. Details for the fire-rated vertical and horizontal assemblies should be included in the construction drawings. Details should represent all assemblies separating the live/work units from adjacent units and spaces, including the existing assemblies to demonstrate compliance. The details should reference listed tested assemblies. See IBC Sections 419.2 and 703.2. 5. Continuing with the previous comment, it is presumed that the spacies being converted to the live/work units may have openings in the horizontal assembly above leading to shafts. Details to seal the openings should be included. The locations of openings to be sealed should be indicated in the drawings. See IBC Section 713.11. 6. The drawings should include penetration details for the walls separating the dwelling and the lobby. See IBC Section 714.4. 7. The units require bathroom and kitchen exhaust, and whole-house ventilation systems. The proposed routing for the mechanical ductwork should be shown. Additional details for fire-rated construction should be specified where ducts penetrate rated assemblies. Dampers should be specified where proposed; dampers may not be specified for the kitchen exhaust. See IBC Section 717. 8. Unit"A" includes a new door through an existing three-hour wall accessing a garage. The unit is required to be separated from the shaft by a minimum three-hour door that also provides smoke protection. The door should be self-closing and self-latching. See IBC Sections 406.3.2.1 419.2, 420.2, 708.6, and 716.2.2.1, and Table 716.1(2). 9. Unit"B" includes a door accessing a three-hour rated stair shaft. The unit is required to be separated from the shaft by a minimum three-hour door that also provides smoke protection. The doors should be self-closing or automatic-closing. Note that the existing door appears to comply with these requirements; they should be specified on the drawings. See IBC Sections 419.2, 420.2, 708.6, 713.7, and 716.2.2.1, and Table 716.1(2). 3200 Cedar Street © 425.257.8810 O everetteps@everettwa.gov Everett,WA 98201 425.257.8857 fax everettwa.gov/permits Page 2 of 4
