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.
Your plan, tailored to how you’ll use it.
Every plan here is a starting point. We reshape the layout — rooms, windows, doors, and the privacy between your ADU and the main house — around how you’ll actually live. All of it included in your fixed plan fee.
The Rental Layout
A private entrance to the side yard, with the bedroom and windows placed away from the main house for maximum separation and sound privacy.
The Family Layout
An open plan with a wide slider facing the main-house patio and an optional pass-through — the ADU reads as an extension of the home.
The Suite Layout
A semi-private one-bedroom with its own entrance but a connecting path and shared outdoor space — independence without isolation.

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.

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.
