• • Taejung Lee Plan Check Number: B2205-001, First Building Review September 8, 2022 General 1. The documents submitted in response to the intake review included brief annotations of the review letter that were not sufficiently clear to indicate the responses to the comments. A response letter is required per Item (a) above to clearly indicate how each comment has been addressed. Architectural 1. The house should have an egress path leading to a public way. The response to the intake comments stating "See Site Plan" is not sufficient; the site plan does not show the required egress. See Section R311.1. 2. Continuing with the previous comment, the proposed work eliminates the exit next to the garage. Egress through the garage is not allowed per Section R311.1. The new designated egress door, landings, and stairs are required to comply with Sections R311.2, R311.3, R311.7, and R311.7.8. The egress route should also comply with Section R311.8 if a ramp is required to reach the public way. See additional structural comments below. 3. The exterior door at the rear of the garage should be provided with a landing per Section R311.3. The step height for the door to landing, and landing to grade, should be specified. See Section R311.3.2. 4. The construction drawings should include a note requiring the smoke/CO 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. Continuing with the previous comment, a heat detector is required in the garage per Section R314.2.3. The detector should be interconnected with the other alarms. 6. The construction drawings specify spray foam insulation to create a non-vented roof over the Pantry/Den area complying with Section R806.5. Details should be included in the drawings. The details should show that the framing is sufficiently deep for the required insulation. 7. The project appears to include installed a new raised floor system in the Pantry/Den area of the house. The following comments should be addressed: a. The floor is required to have insulation with a minimum thermal value of R-30. See WSEC Table R402.1.1. b. The floor step at the garage door should not exceed 7.75 inches per Section R311.3.2. c. The floor may result in a vertical clearance that is less than 7 feet as required by Section R305.1. The minimum required height should be maintained and specified in the drawings. 8. Seismic restraints should be specified for the water heater per Section M1307.2. 9. The project includes exposing the exterior envelope cavities for the entire building. The building is required to be insulated per WSEC Section R503.1.1. The minimum required thermal rating for the exterior walls is R-15. 0 3200 Cedar Street CD 425.257.8810 O everetteps@everettwa.gov Everett,WA 98201 425.257.8857 fax everettwa.gov/permits Page 2 of 3
