How much does a detached ADU cost in Los Angeles?

Our detached ADUs run from roughly $185,000 for a 400–500 sq ft studio to $420,000 for a 900–1,200 sq ft two-bedroom. The ranges reflect recent detached projects in Los Angeles County and vary with site conditions, utility distance and finish level. A fixed price follows the free site assessment.

How long does it take to build a detached ADU?

Construction takes 12–16 weeks for a studio, 16–20 weeks for a one-bedroom and 20–26 weeks for a two-bedroom. Design takes 4–6 weeks and permits about 6. From first site visit to keys, a project typically runs 6 to 9 months, and you get the full calendar before you sign.

What is included in the price?

The fixed price covers design, permits, utilities, finishes and landscaping. Every ADU we build has its own connections and, where it makes sense, its own meter: we trench and connect to the existing sewer lateral, upsize the main panel if needed, and pre-wire for solar and EV.

How does the process work?

Five steps, one contract, one point of contact. We handle the site assessment and feasibility, design with 3D renderings of your exact backyard, the entire city permit process (average approval: 6 weeks), construction with a dedicated project manager and a weekly photo report, then turnkey delivery once the final inspection has passed.

More questions about detached ADUs

Yes, and we handle all of it. California state law requires cities to approve compliant ADUs within 60 days; in practice our submissions to LADBS are approved in about 6 weeks because we design to the code from day one and pre-clear the tricky items (setbacks, fire separation, utilities) before filing.
