Pre-Approved ADUs
Pre-approved ADUs, delivered across your area.
Our vetted builders have delivered ADUs for homeowners, rebuilds, and multi-unit properties. State pre-approved plans compress the permit timeline, so projects go from signed contract to installed faster than site-built construction.
How It Works
From first call to move-in.
See if your property qualifies — free.
Tell us your address and we'll do a free desk review of your zoning, lot size, and setbacks to tell you straight whether your property can support an ADU. No cost, no commitment.
Get matched with a vetted builder.
If your lot looks viable, we connect you with a CSLB-licensed, bonded, vetted LA ADU builder for a free on-site feasibility assessment — and one guaranteed, fixed price.
Your builder handles permits and site prep.
Your matched builder manages city permits and prepares your site while your ADU is built, so the timeline stays tight.
Installed fast.
Your builder's crew completes the installation and finish work on site. Most projects go from signed contract to move-in or lease-up in six to eight months.

Rental Income Calculator
What could your ADU earn?
Estimate your monthly rental income based on your location and ADU size, using current Los Angeles-area rental data.
Estimate for Silver Lake (90026)
Estimates use Los Angeles-area long-term rental data (HUD FY2026 fair market rents & Zumper, June 2026) adjusted for ADU size and ZIP. Actual rent varies by condition, finishes, parking, and market timing — this is an estimate, not a guarantee. Furnished mid-term (30+ day) figures assume a furnished unit; short-term/nightly rentals of a detached ADU are restricted under LA's Home-Sharing Ordinance. The increase in property value is an estimate using the income (capitalization) approach — net rental income capitalized at a ~5.5% Los Angeles residential cap rate — not a formal appraisal.
