How to write a garage conversion permit narrative
Garage conversions trip on habitability requirements: light and ventilation, egress, ceiling height, insulation, and conditioning. Your narrative should walk through how the space becomes legally habitable — and be upfront about the garage door infill and parking implications, which many jurisdictions regulate.
What your narrative needs to include
- New use of the space (bedroom, office, living space — or ADU, which is a different application)
- Garage door removal and infill wall construction
- Egress: window sizing or door requirements for the new use
- Insulation and conditioning for habitable space
- Floor elevation/moisture handling over the slab
- Electrical upgrades for habitable-space outlet spacing and alarms

Project Description
This project involves conversion of an existing attached two-car garage (approximately 400 square feet) into a family room. The garage door opening will be infilled with a framed insulated wall matching the existing exterior, and the space will be finished and conditioned to habitable standards.
Scope of Work
- Remove garage door and hardware; frame infill wall with 2x6 studs on new curb, matching existing stucco exterior with one new dual-pane window
- Fur and insulate existing exterior walls to R-13+; insulate ceiling to R-30
- Install moisture barrier and sleeper subfloor system over existing slab
- Add electrical outlets to habitable-space spacing per NEC 210.52, plus smoke and CO alarms
- Extend existing HVAC with one new supply and return duct
- Install egress-compliant window in infill wall
Materials & Methods
2x6 framing, R-13 and R-30 fiberglass insulation, dual-pane vinyl egress window, moisture barrier and plywood subfloor, drywall finish.
Work Not Included
Plumbing work. Driveway modification. Conversion to a dwelling unit (no kitchen proposed).
Contractor Statement
All work will be performed per the currently adopted residential, energy, and electrical codes to meet habitable space requirements.
Mistakes that get garage conversion permits kicked back
- Not addressing the garage door infill — reviewers always ask
- Silence on egress for the new use
- Skipping slab moisture treatment
- Ambiguity about whether this is an ADU (changes the whole review path)
