• Mr. Robert Smith Mac Donald MD Projects &Services Consultants Plan Check Number: C2010-004, Second Building Review March 18, 2021 General 1. The structural drawings include the detached carport on the west side of the building. It is acceptable to include this structure in the same permit application with the modifications to the house. The architectural drawings should be revised to also indicate the carport as part of the proposed construction and provide additional information not included in the structural drawings. See Section R106.1.1. Architectural Original Comments: 3. The following comments should be addressed for the Attic level: a. The egress width at the top of the stairs is shown with the correct 3-foot clearance on the Attic Floor Plan 2/A.101. However, the clearance in Section 3/A.102 is incorrectly show and should be provided between the wall and the guard post. The drawings should be revised. See Section R311.6. b. Hallways should comply with IRC Section R311.6. Note that the hallway appears to only provide a maximum height at one side of 7 feet. This can be accepted. However, it is noted that Section 2/A1.00 and Attic Floor Plan 2/A.101 do not show the same ceiling height, and the door is not located the same relative location to this height. The minimum 7-foot clearance must be maintained. See other comments below that may impact this clearance. c. Stair Section 3/A.102 specifies cable guards with a 4-inch spacing. Cables are not sufficiently rigid and can splay, and do not comply with this requirement. The cable spacing should be reduced. See Section R312.1.3. g. The project appears to show modification of the attic into habitable space; note that the Attic Floor Plan 2/A.101 appears to incorrectly state this level as"unfinished attic". Section 2/A.102 specifies R-28 insulation between the 2x6 rafters. The minimum insulation at these locations, including the sloped ceiling in Section 1/A.1-2, should be R-38; this insulation should be continuous through the center area of the roof. Note that the structural plans indicate the roof framing is 2x8 construction. The correct framing should be shown consistently, and the insulation revised as required. The framing depth should not impact the minimum head clearances as discussed in Architectural Comment 3(b). See also Structural Comment Additional Comments: 4. The plans show construction of a new stairway in Section 3/A.102. The required 10-inch stair tread depth should be measured from nosing to nosing. The stairway and floor framing should be revised. This may impact the minimum egress clearances around the stairs, such as but not limited to the clearance at the Attic between the stair guard and the door. 0j 3200 Cedar Street 0 425.257.8810 ,{ everetteps@everettwa.gov �% Everett,WA 98201 425.257.8857 fax everettwa.gov/permits �ge2of3)
