Model Habitability on Day One
Compliance starts with geometry. Draft ridge-aligned sections and a reflected ceiling plan to verify minimum ceiling height over the required floor area—only zones above the threshold count as habitable. If you’re short, design dormers or selective reframing early so structure, energy modeling, and exterior review are baked into the set. Overlay a furniture plan to keep circulation clear of low slopes and to position sleeping/working zones where headroom is comfortable.
Egress, Stairs, and Daylight
For bedrooms or many finished attics, provide a compliant means of egress: either a stair meeting rise/run/headroom or an emergency escape and rescue opening (EERO) with code net clear opening and sill height. Roof windows that serve as EERO must meet manufacturer pitch limits and have insulated, air-sealed shafts. Balance daylight with glare control—pair south/west apertures with low-SHGC glazing and blackout shades.
Systems Routing Without Compromise
Pre-route HVAC, plumbing, and electrical before finalizing partitions. A variable-speed heat pump or slim-duct air handler inside the envelope simplifies comfort and dehumidification; ERV supply/exhaust runs should be short, insulated, and accessible for filter changes. Reserve a rear service chase behind knee-wall millwork so future upgrades don’t open finished walls.
Drawings That Sail Through Review
Put full stair sections, window schedules with net clear dimensions, guard/handrail details, and roof assembly notes (R-values, vapor control, air barrier continuity) on the sheets—not only in general notes. Include cut sheets for skylights, insulation, and fans. This clarity reduces RFIs and keeps the filing timeline predictable.
