Garage Conversion
Garage Conversions in Sacramento, CA
Definition
What is a garage conversion?
A garage conversion turns an existing attached or detached garage into a legal, permitted ADU with a kitchen, bathroom and living space. Because the structure already exists, conversions within the existing footprint generally avoid setback issues and replacement parking, making them one of the fastest and most affordable ways to add a unit in Sacramento.
Who is a garage conversion best for?
- Older Sacramento neighborhoods with detached garages on alleys, like East Sacramento, Land Park and Midtown
- Homeowners who want an ADU for a lower budget and a shorter timeline
- Owners who no longer park in the garage
- Lots where a new detached unit would not fit the setbacks
How big can a garage conversion be?
A garage conversion uses the existing footprint, so the size is set by your garage. A typical two-car garage is about 400 to 480 square feet, enough for a comfortable studio or compact one-bedroom. In some cases a modest expansion is allowed, which then has to meet current setbacks for the new portion.
How long does a garage conversion take?
Most garage conversions take about 6 to 10 months from first site visit to move-in. Construction itself is often 3 to 4 months. The biggest variable is the condition of the existing slab and framing.
How much does a garage conversion cost in Sacramento?
$80,000 to $150,000
Garage conversions in the Sacramento area typically range from $80,000 to $150,000. The slab condition, the sewer path to the street, insulation and window changes, and whether the garage is attached or detached drive the price.

How we build it
How we design, permit and build your garage conversion
- 01
Inspect the shell
We check the slab, footings, framing and roof before quoting, because the existing garage decides the scope.
- 02
Plan the plumbing path
We locate the sewer lateral early. Trenching across a yard is often the single biggest unknown.
- 03
Make it feel like a home
New windows and an entry replace the garage door, with insulation, drywall and finishes that do not read as a garage.
- 04
Build fast, inspect clean
Because the structure exists, our crews move quickly through rough-ins and inspections.
Is my garage a good candidate for conversion?
Most garages can be converted. The best candidates have a sound slab, framing without major rot or termite damage, and a reasonable path for a sewer line to the main lateral. Detached garages on alleys in older Sacramento neighborhoods are often excellent candidates. If the structure is in poor shape, it may be smarter to demolish and build a new detached ADU on the same spot, which we can price side by side.
