• • Mr. Joey Perez Drafting Northwest Plan Check Number: B2201-011, First Building Review April 26, 2022 General 1. The Proposed Floor Plan on Sheet A6 shows eight resident rooms. The adult family home (ADF) is limited to six residents. Two rooms should be designated as non-resident rooms. In addition, the General Notes on Sheet Al should include a note stating that the ADF is limited to a maximum of six residents. See the ADF definition in Section R202. Architectural 1. The partial Ramp Plan on Sheet A4 and the Proposed Floor Plan on Sheet A6 should specify a minimum interior clearance of three feet between the ramp guards. See Section R106.1.1. 2. The CareTaker and Office rooms in the Proposed Floor Plan on Sheet A6 do not comply with the minimum area and dimension requirements of Section R304. The design should be revised. 3. Sheet A2 includes the energy credit schedule per WSEC Section R406. The following comments should be address: a. Option 1.1 is selected requiring vertical fenestrations with a maximum thermal performance of U=0.24. The schedules on Sheet A2 should be revised to show this value. In addition, the Proposed Floor Plan and the"Legend"on Sheet A6 should remove the U=0.28 values as these conflict with the maximum allowable value. b. Options 3.2 and 5.3 are selected for energy efficient systems. The performance requirements for each system should be specified in the construction drawings. 4. The project requires a whole house ventilation system per IRC Section R303.4. The drawings should show the location(s) of the system component(s), and specify the performance requirements per Section M1505.4.1. The system should be located in a central area that is open to and has unobstructed air flow with the majority of the habitable space. Alternatively, if the system is not centrally located, the system should provide ducting to each room of the house per Section M1505.4.1.1, and the drawings should specify a requirement for testing to verify air flow rates per Section M1505.4.1.6. The system should not have a sound rating exceeding 1.0 sones. 5. The kitchen should specify an exhaust fan including the minimum required performance rate per IRC Table M1505.4.4(1). 6. Detail 1/A3 appears to show a ventilation baffle over the insulation. This should be clarified. See Section R402.2.3. 7. Seismic restraints should be specified for the water heater per Section M1307.2. 0 3200 Cedar Street 425.257.8810 0 everetteps@everettwa.gov Everett,WA 98201 0 425.257.8857 fax everettwa.gov/permits Page 2 of 3
