ADU Construction in Tarzana — Built Start to Finish

Only work listed as express-permit eligible can bypass plan review and proceed through PermitLA. We check the exact scope against that eligibility list before choosing the submission path. Plan for LADBS review when developing your ADU proposal; the department’s building permit guidance explains how the work scope determines the permit process.

Start with the condition of the foundation, framing and building enclosure. New work used to convert or legalize an accessory building as an ADU must meet current codes and applicable Los Angeles Green Building Code requirements. We assess the structure and identify needed insulation, energy and life-safety upgrades so the conversion scope accounts for more than the interior layout.

LADWP requires construction to avoid its lines, rights-of-way and easements, so utility routes belong in the initial layout discussion. We review service capacity, meter location and address assignment while planning the ADU. Multiple-meter ADUs need separate legal addresses, and utility service requests have their own approval process to coordinate alongside the building permit.

We coordinate design, engineering, permit submissions, correction responses, construction and inspections under one contract. On a hillside property, that starts with access, drainage and applicable fire-review requirements; for a conversion, it includes evaluating the existing structure. Our ADU construction service brings these steps together, including specialty-trade coordination and owner involvement during permitting.
