Planning your project
In San Francisco, the median estimated construction cost on garage conversion permits for single-family and two-family homes was $75,000 over the last 12 months. That figure is what the applicant expected the permitted work to cost. It is not a contract price, so it does not tell you what your own project will cost.
The real cost of a garage conversion is often higher than the permit estimate. Design choices, materials and finishes, work that is not on the permit, and the condition of the home can all change the total. A garage that needs new structure, utilities or repairs usually costs more to convert than one that is ready to use.
The most reliable way to know is an estimate for your home. Describe your garage, your goals and any known problems, and a local builder can price your specific project.
Garage conversion cost questions
Is the permit's estimated cost the real cost?
No. The figure is the estimated construction cost written on the permit application, which is what the applicant expected the permitted work to cost. Real project costs are often higher, so treat it as a starting point only.
What drives the price of a garage conversion?
Design, materials and finishes, the structural and utility work the space needs, work that is not on the permit, and the condition of the home all affect the price. No two garages start in the same state, so each project is different.
Why do estimates differ?
Two builders may scope the same garage differently. The San Francisco median is a midpoint across many homes, so it will not match every project.
How do I get a reliable number for my home?
Ask a local builder for an estimate based on your garage, your plans and your goals. You can also check any contractor's license status with the CSLB (Contractors State License Board).

Garage conversions in San Francisco often need permits. Over the last 12 months, 143 garage conversion permits were issued across all property types, and 90.2% of them were for single-family and two-family homes. Ask your builder which permits your project needs.
How long does the permit process take?
