Your garage is your best square footage.
Garage-to-ADU and garage-to-living-space conversions across Los Angeles — a new room, rental, office, or gym without expanding the house, at a fraction of new-construction cost.
A new room hiding in plain sight.
The cheapest square footage you can add is the square footage you already own. A garage conversion repurposes an existing structure — foundation, walls, and roof already paid for — into space your family or a tenant uses every day.
We start with a thorough site assessment: structural integrity, zoning laws, permit requirements, and budget, reviewed before design. Then our team produces layouts and 3D renderings tailored to the use you have in mind.
Construction covers everything the structure needs to become livable — insulation, flooring, windows, electrical, plumbing, and HVAC — code-compliant and finished to match your home.
Typical cost & timeline by conversion type.
Real ranges from our completed projects. Your estimate is confirmed after the free assessment.
| Conversion type | Typical cost | Timeline | Notes |
|---|---|---|---|
| Living space / bedroom | $35,000–$80,000 | 2–3 months | Insulation, flooring, HVAC |
| Home office / gym / studio | $35,000–$70,000 | 2–3 months | Lighter plumbing needs |
| Full ADU with kitchen & bath | $50,000–$150,000 | 3–6 months | Rental-ready, separate entrance |
| Two-story garage addition | $100,000+ | 4–8 months | Space above and within |
Ceilings must meet a 7-foot minimum and energy upgrades (insulation, windows, HVAC) are usually required to meet residential code — we scope all of it up front.
For every garage storing nothing worth storing.
Single-car garages typically yield 400–600 square feet of living space — a studio, suite, office, or income unit.
These are the conversions we build most.

Planning a bigger project? Garage Conversions often pairs with ADU Construction, Room Additions, or Interior Remodeling — we can scope it all together.
Problems we solve
- A garage full of boxes on a lot that could earn rent
- No guest room, office, or gym in a house that needs all three
- New-construction costs that don’t pencil out
- Unpermitted conversions that surface at appraisal or sale
Common triggers
- Working from home in a corner that was never meant for it
- A parent or adult child who needs a place of their own
- Rental income that would meaningfully help the mortgage
- Seeing a neighbor’s conversion and realizing yours could match
