No phone calls. No high-pressure pitch. Just a real number you can plan around, based on your lot, your project type, and your finish level.
Real range based on your selections — no email gate, no waiting.
Three things kill most ADU projects before construction. We fix all three before you sign anything.
Cheap bid wins the job by quoting low — then change orders run the price up 15-25% by month four. Industry average overrun in LA: $30-80k.
The wrong contractor doesn't know LADBS. Plan revisions stack up. What should be 3-6 months turns into a year of waiting.
Most contractors bid-shop the framing, MEP, and finish to whoever's cheapest. Different crews every week. Quality slips. Communication breaks.
Four steps from "thinking about it" to "moved in." No surprises.
You answer ~10 quick questions. You get a real cost range immediately. No email gate.

Honest 2026 range: $200k-$400k for a new detached build, $90k-$180k for a garage conversion. Biggest variables: site access, finish level, permit complexity. We walk your property and give you a real number — no phone-call quotes.
Permits run 3-6 months in LA. Build is 6-9 months for new construction, 3-5 for garage conversions. Plan on a year start to finish for new builds.
