Why this plan

The case for the 2-Car Garage Conversion Plan.

Most Los Angeles garages are two-car — which is exactly why this is the volume seller of the line. The plan turns that standard footprint into a genuine one-bedroom home: a separate bedroom, a full bathroom, and an open living-and-kitchen space, all inside the walls you already have. No new foundation, no lost yard, and the fastest, most permit-friendly path to a backyard rental or in-law suite.

  • No new foundation Converts the standard two-car footprint as-is.
  • A real one-bedroom A bedroom, full bath, and open living + kitchen.
  • No replacement parking AB 68 / SB 1211 ended that requirement.
  • Keeps its setbacks Even under four feet from the property line.
  • ~60-day ministerial review The fastest, most permit-friendly ADU path.

Why the build price is a “from”

Every garage is different.

The plan and the plan fee are fixed. The build starts at $150,000 — the final number depends on what your specific garage is hiding. An on-site assessment gives you a real number, not a guess.

Ceiling height
Code requires 7′0" finished, and you lose 4–6" to floor and ceiling assemblies. Below about 7′6" raw, the roof has to be raised.
Slab & footings
Older garages often have shallow, unreinforced footings that need underpinning, plus leveling and vapor-barrier work on thin slabs.
MEP
Most garages have no plumbing and limited panel capacity; new electrical and plumbing runs can approach new-build cost.
Insulation & Title 24
Garages carry little to no insulation or ventilation, so a full envelope upgrade is required to pass energy code.
Fire separation
Attached garages need one-hour rated assemblies between the ADU and the main house.

Questions

2-Car Garage Conversion Plan — frequently asked

How big is a 2-car garage conversion ADU?
A typical Los Angeles two-car garage is about 400–440 sqft. That is enough for a comfortable one-bedroom layout: a bedroom that fits a queen bed, a full bathroom, and an open living-and-kitchen area with room for a small dining table.
How much does a 2-car garage conversion cost?
The permit-ready plan set is a fixed $7,490. The build starts at $150,000 with an independent licensed general contractor and is confirmed for your specific garage after an assessment — ceiling height, slab, and existing wiring are what move the final number.
Can I build it myself or use my own contractor?
Yes. You own the permit-ready plans. Build it yourself, bring your own licensed contractor, or build with one of our vetted construction partners — whichever you prefer.
Do I need replacement parking if I convert my garage?
No. AB 68 / SB 1211 (effective January 2025) eliminated replacement-parking requirements for garage-to-ADU conversions statewide. You keep your driveway and yard.
What happens to my setbacks?
A legally established existing garage keeps its current location and setbacks, even if it sits under four feet from the property line. That is one of the reasons a conversion is the easiest ADU to permit.
Why is the build price a "from" number instead of a fixed price?
The plan and the plan fee are fixed. The build starts at our published number, but the final price depends on what your specific garage is hiding — its ceiling height, its slab, its wiring. An on-site assessment gives you a real number instead of a guess that balloons later.

Signature Garage Conversions are designed in-house by our expert ADU design team and carry the same curated finishes as our detached Signature Homes. Your plan fee is fixed. Because every garage is different — ceiling height, slab condition, existing wiring — the cost to build is an estimate that starts at the figure shown and is confirmed for your specific garage; it is not a single guaranteed price. Construction is performed by an independent licensed general contractor.
