ADU rental income in Los Angeles.
A well-built ADU in the LA area typically rents for $1,800 to $3,500 a month, depending mostly on size and area. Here’s what that looks like broken down, and how to weigh it against what an ADU actually costs to build.
Rough rent ranges by size
The most affordable to build, and the lowest rent ceiling — but also the fastest to recoup per dollar spent on the smallest unit.
The most common ADU size in LA, generally seen as the sweet spot between build cost and achievable rent.
A meaningfully higher rent ceiling than a one-bedroom, for a real but proportionally smaller jump in construction cost.
The top of the typical range — approaching small-house territory in both cost and achievable rent.
What moves the number
- Area. Westside units (Santa Monica, Culver City, Venice, West LA) have generally commanded the highest rents in the LA area, often above $2,800. San Fernando Valley and San Gabriel Valley units typically run somewhat lower.
- Build quality. A well-designed, higher-finish unit has generally rented for several hundred dollars more per month than a basic one in the same neighborhood — not a one-to-one return on the extra construction spend, but a real difference.
- Bedroom count. Going from a studio to a one-bedroom, or one to two bedrooms, tends to add meaningfully more in achievable rent than it adds in proportional construction cost — one reason most LA ADUs built for rental income skew toward one or two bedrooms rather than studios.
Gross rent isn’t take-home income
Vacancy, maintenance, insurance, and property taxes all come out of the number above before it’s real income — budgeting roughly a quarter of gross rent toward these costs is a reasonable starting assumption, though your actual numbers will depend on your specific situation. This page isn’t financial advice; run your own numbers, or talk to an accountant, before treating a rental ADU as an investment decision.
To weigh rental income against what you’d actually spend building it, see our ADU cost guide — comparing the two ranges side by side is the real starting point for deciding if a rental ADU makes sense for your property.
Rent ranges synthesized from multiple ADU builder and rental-market sources for 2025-2026; most have a commercial interest in sounding optimistic, and actual achieved rent (versus listed asking rent) can run lower. Treat these as planning ranges, not a guarantee.
