Garage Conversion
A garage conversion turns an attached or detached garage into finished living space such as a bedroom, office, or ADU. It reuses the existing slab and structure but requires insulation, egress, and often HVAC, and is priced per project.
How garage conversion is done
- Verify zoning and parking requirements for converting the garage
- Frame and insulate walls, and replace the garage door with a wall or windows
- Raise or level the slab and address moisture if needed
- Rough-in electrical, plumbing, and HVAC
- Insulate, drywall, and install flooring
- Final finishes and inspection
What homeowners should know
- Confirm your city allows the conversion and any required replacement parking
- Plan for insulation and HVAC since garages are not conditioned
- Ask about raising the slab to meet interior floor height
- Decide whether you need plumbing for a bath or kitchenette
- Consider resale impact of losing garage space
Permits, timelines & things to consider
- Permits are required, and some cities mandate replacement off-street parking
- The uninsulated slab and walls need insulation and conditioning to be livable
- Egress and ceiling height must meet residential code
- Cost drivers are HVAC, plumbing additions, and slab work
- Timelines typically run four to eight weeks
Frequently asked questions
Do I need a permit to convert a garage?
Yes, converting a garage to living space requires permits and inspections, and some cities require replacement parking.
Is a garage conversion good for resale?
It adds livable square footage but removes covered parking, so the net effect on resale depends on your market and buyer preferences.
Does the garage need new insulation and heating?
Yes, garages are unconditioned, so insulation, HVAC, and often a raised, insulated floor are needed to make the space comfortable and code-compliant.
