01 — What's Included
What's Included in a GarageConversion
A garage conversion turns an attached or detached garage into a self-contained living unit with its own kitchen, bathroom, and entrance. It is a strong fit for homeowners who want space for family or rental income without giving up yard, and for investors who want to add a unit at the lower end of the ADU budget range.

How Our Garage ConversionProcess Works
- 01
Consult
Text, call, or send the form for your free ADU property and investment analysis. We review your garage's slab, framing, ceiling height, and utilities, then talk through your goals, budget, and preliminary feasibility.
- 02
Design
We develop the concept — size, layout, and finish level — for your garage conversion and coordinate architectural and engineering work based on the final scope, then deliver a written estimate you approve before we move to permitting.
- 03
Permit
We submit for plan check and coordinate every permit requirement with the applicable jurisdiction so your project is fully approved before construction starts.
- 04
Build
From framing and MEP rough-in through finishes, we manage the defined scope, selections, and schedule, with inspections at every stage. Garage conversions typically run toward the shorter end of our 3 to 6 month range because the shell already exists.
- 05
Turnover
Final inspection, punch-list completion, and a complete handoff of your finished garage conversion, backed by our 1-year workmanship warranty.

05 — FAQ
Common Questions About GarageConversions
How much does a garage conversion cost?
Most of our ADU projects fall between $120,000 and $340,000. Garage conversions typically land at the lower end because the structure, slab, and roof already exist. Your written estimate after the site visit will show exactly where your project falls.
How long does a garage conversion take?
Our builds run 3 to 6 months. Conversions usually finish faster than ground-up construction because the shell is already in place. We give you a realistic timeline before work starts.
Can I still park in the garage after the conversion?
No. A converted garage becomes living space. During the site visit we talk through where vehicles will go and whether that affects your plans.
Does a garage conversion count as a real ADU?
Yes. A garage conversion with its own kitchen, bathroom, and entrance is an accessory dwelling unit and can be used for family or rental income. We design every conversion to function as a complete home.
What areas do you serve for garage conversions?
We serve properties within about 30 miles of Cerritos across Los Angeles County and Orange County. If you are near the edge of that range, reach out and we will confirm.
What should I compare when I'm getting bids from other ADU builders?
Before you compare bids, compare scope. Ask every builder to spell out, in writing, who is responsible for design and engineering, utility and electrical-service work, and foundation and structural scope; what cabinet, counter, flooring, and tile allowances are included; who handles permit and inspection responsibilities and site concrete, drainage, and exterior work; what the change-order process and exclusions are; and what your completion, punch-list, and warranty responsibilities look like. We put all of it in writing before you sign.
