ADU vs. Garage Conversion in Los Angeles
Two paths to the same goal, with different cost, timeline, and trade-offs.
A garage conversion is a type of ADU, but the experience of building one is different from a detached unit. Choosing between them comes down to budget, how you will use the space, and what your lot supports.
Garage conversion: faster and usually cheaper
Because the foundation, walls, and roof already exist, a conversion typically costs less and moves faster. The trade-offs are size limits, ceiling height, and giving up covered parking.
Detached ADU: more flexibility, more site work
A new detached unit gives you privacy, layout freedom, and strong rental appeal, at the cost of more site work, longer timelines, and a higher budget.
How to decide
- Tight budget and an existing garage: lean toward conversion.
- Long-term rental income and privacy: lean toward detached.
- Limited rear yard: a conversion may be the only fit.
