Permit-ready ADU plans, guaranteed.
We design your ADU and run the permit through your city — 126 permitted across LA, not one denied. If we can't permit yours, you get your plan fee back.
The lowest-risk first step. A Backyard Review.
Your Backyard Review
On a 15-minute video call we pull up your actual lot, show you which ADUs fit, and map your path to permit — no pressure, no obligation. Want it in writing? The $490 ADU Game Plan gives you a full written feasibility report, credited 100% toward your design.
Permit-ready plans. One fixed price each.
Each home shows two numbers: the fixed price you pay us for the architect-designed plans and permit processing, and the estimated cost a licensed builder charges to construct it. We sell the plans and run the permit; the build is an estimate, not our price.

Plan fees are fixed. The construction figures are typical ranges charged by independent licensed general contractors. We introduce you to vetted builders who build our plans. Site-specific costs are identified and priced before you commit, during your Backyard Review. Signature plan fees are for the model as designed; modifications are billed at $155/hr, and a custom design starts at $9,990, bid to your project. Run your own numbers in the ADU cost calculator.

We design and permit. A licensed builder constructs.
When your permit is approved, we introduce you to vetted, independent licensed California general contractors who build CALI ADU plans regularly. You contract construction directly with the builder; we stay in your corner as your design and plans partner. The construction estimates on this page reflect what those builders typically charge.
