ADU construction in Los Angeles

Garage conversions in LA typically run $140,000–$220,000 all-in — structure, utilities, finishes, and fees. Detached new-construction ADUs generally land between $280,000 and $400,000+, driven by size, site access, and utility upgrades. Hillside lots add cost; flat Valley lots are the sweet spot. The free feasibility consultation prices your actual parcel.

Almost certainly yes. California state law (AB 68 and successors) requires cities to allow at least one ADU plus a junior ADU on most single-family lots, overriding older local restrictions. Setbacks as small as four feet, no added parking near transit, and by-right approval for units under state size limits. The consultation starts with a parcel check so you know exactly what your lot allows.

The City of LA maintains a Standard Plan Program — a catalog of ADU designs already reviewed by LADBS. Building from one skips most architectural plan check, often saving one to three months and real design fees. Many of our partner builders work with pre-approved plans or have their own approved sets; it's worth asking about at the consultation.

One-bedroom ADUs across LA commonly rent for $1,800–$2,800 per month depending on neighborhood — Westside units at the top, Valley and East LA in the middle of the band. Against a $180,000 garage conversion, many owners see gross yields that beat most alternatives, plus long-term flexibility for family. Your consultation can include a rent-range reality check for your zip.

Garage conversions: typically 5–7 months end to end, including permits. Detached new builds: 7–10 months. Pre-approved plans compress the front half; utility upgrades (panel, sewer connection) are the most common schedule risk, which is why feasibility checks them first.

No. Construction is performed by an independent CSLB-licensed, insured California contractor from our partner network with real LA ADU experience. We book your free consultation; you contract directly with the builder.
