Maria Bedolla 6504 Highland Drive B2306-007 General 1. The project description on sheet A1.0 indicates that the ADU will have two stories, but the drawing set only indicates one story. Architectural 2. It appears that the property line is within five feet of the exterior wall of the ADU. This wall should have a minimum fire-resistance rating of 1 hour. IRC R302.1 and Table R302.1(1). 3. It appears that the property line may be less than three feet from the exterior wall of the ADU. Openings in walls are not allowed if the fire separation distance is less than three feet. IRC R302.1 and Table R302.1(1). 4. A landing outside the exterior door should be shown. The width of the landing needs to be not less than the door serviced and have a dimension of not less than 36 inches in the direction of travel. IRC R311.3. 5. A landing at the top and bottom of each stairway should be shown. The width of the landing should be not less than 36 inches in the direction of travel. IRC R311.7.6. 6. It appears that the minimum net free ventilating area of 1/300 of the area of the vented attic space was checked in the plans. The plans should show that the minimum net free ventilating area is 1/150 of the area of the vented attic space unless the exceptions are met, however the Climate Zone exception is not met as Everett is in Climate Zone 4. IRC R806.2 and WSEC R301.1. 7. The R-48 insulation in the ceilings, as shown on Sheet A4.0 (and similar) should be revised to state it is R-49 insulation. WSEC R402.1.1. Energy &Whole House Ventilation 8. It is understood that sheet A2.2 states to refer to Mechanical Drawings that will be in a deferred submittal for the location of mechanical equipment. However, the plans should indicate a whole house ventilation system will be installed per IRC Section R303.4. Structure 9. The project involves converting a non-habitable building (i.e., garage) to a habitable building (i.e., dwelling). However, it appears that the wall framing is being modified at this area of the structure and there are no structural details or calculations indicating any modifications are taking place to the structural framing. Calculations substantiating the capacity of the walls should be submitted for review.
