Frequently Asked Questions

How much does a garage conversion cost?

Expect $20,000-$50,000 for a 2-car garage (400 sq ft). Per square foot costs run $25-$60 depending on finishes and HVAC needs.

Do I need a permit?

Yes. Converting a garage to living space requires building permits and must meet residential building codes for egress, insulation, and ceiling height.

Will it affect my home value?

It depends on your market. In areas with parking shortages, losing a garage can hurt value. In high-cost areas, the added living space often increases value.

What about the garage door opening?

You can frame in a wall with windows ($1,500-$4,000) or keep the garage door for flexibility. Most conversions replace it with a standard wall.
