Garage Conversion

Garage Conversions: Plans, Energy Code, and Permit

Turning a garage into an ADU, bedroom, office, or other living space takes more than new drywall.

What is involved

  • Existing conditions: as-built drawings of the garage
  • Floor plans and elevations
  • Energy code for the converted space (see Remodel Energy Code)
  • Parking and zoning
  • Structure, insulation, and egress
  • Permit runner to submit and track

ADU or living space?

The rules differ, and we sort out which path fits your lot and your goals.

If an air leakage test is required for an ADU, it comes from WA Blower Door. We do not build and we do not engineer or stamp. Where engineering is required, our sister firm Dow Engineering PLLC, in the same office, handles it.
