About ADU Builder in Los Angeles
Every LA lot carries its own LADBS plan-check pattern. Hillside overlays, coastal review zones, R1 versus R2 lots, alley access, and aging sewer laterals all change what your ADU costs and how fast it gets built. We walk yours before drawings begin so the scope holds up through permit, construction, and rental.
Our LA ADU work is a fixed-scope contract: feasibility, design, permits, construction, and closeout — with weekly homeowner updates and a single point of accountability from brief to keys.
What we resolve before drawings begin.
- 01
LADBS plan-check first
We run feasibility against LADBS, LA County, and your jurisdiction's small-lot rules before the brief is signed. No surprises after deposit.
- 02
Setbacks, hillside, and alley access
Hillside lots and rear-loaded alleys behave differently than flat R1 parcels. We confirm setbacks, fire separation, and access during the feasibility brief.
- 03
Sewer, water, and panel capacity
Older LA neighborhoods often need lateral upgrades or a panel upsize before an ADU connects. We scope this up front so it lives in the contract, not in a change order.
