Garage conversion ADUs in San Jose
Turn an attached or detached garage into a permitted home with insulation, windows, a kitchen and a bathroom.
Why convert a garage?
The structure is already there, so a conversion often costs less and moves faster than a new cottage. California law also says the lost garage parking does not have to be replaced.
What does a garage need?
- A slab check, sometimes a new floor over it
- Insulation, drywall and windows
- Plumbing for a kitchen and bathroom, often through the slab
- Electrical capacity and a separate entry
What can surprise owners?
An old slab without a moisture barrier, a sewer line that sits higher than the new bathroom, or framing that does not meet current code. We check all three before pricing.
Garage conversions in San Jose
Conversions reuse the structure and avoid replacing the lost parking under state law. We check the slab, the sewer height and the panel before pricing.
