ADU Builder · Encino
Your Encino backyard has room for a second, smaller home. We design it, permit it through LADBS, and build it with our own crews.
ADU Builder in Encino
Encino lots run big and mostly flat, especially south of Ventura Boulevard, which makes them easy to build on. Maybe your ADU houses your parents in one of the estate neighborhoods. Maybe it becomes a rental near the boulevard. On land priced like Encino’s, a detached ADU or guest house is square footage that earns its keep.
Athenian Builders Group is a licensed California general contractor (CSLB #1045030) that designs and builds ADUs across Encino with one accountable team. You get a fixed price in writing, a firm timeline, and a 2-year workmanship warranty. See our full ADU construction services.
Permits
Encino is part of the City of Los Angeles, so ADU permits go through LADBS (Los Angeles Department of Building and Safety). We prepare the drawings, file the application, and manage plan check and inspections through final approval. The paperwork stays on our desk, not yours.

Why Athenian
Most “ADU builders” are design shops or brokers who sub the construction out. We are a single self-performing team: we design it, pull the permits, and build it with our own crews. That means one point of contact, a fixed itemized price before we start, a firm timeline in writing, and a written 2-year workmanship warranty on everything we build in Encino.
Questions
Yes. We build ADUs across Encino, from the flats south of Ventura Boulevard to the hillside streets. Design, permits, and construction, all handled by our own team.
Encino is within the City of Los Angeles, so permits are issued by LADBS. We manage the full submittal and inspection process for you.
It depends on type and size. A garage conversion typically runs $100k–$180k. A detached new-build lands between $250k–$450k. You get a fixed, itemized price after a free on-site walkthrough.
Most of our ADUs finish in 3 to 5 months. Type, size, and city review times move that number, so we put a firm timeline in writing before construction starts.
