ADU Builder · Studio City
A guest house for your parents, a studio steps from the back door, or a rental that pays part of the mortgage. Built on Studio City lots, permitted through LADBS.
ADU Builder in Studio City
Most Studio City lots have room for a second, smaller home in back. For plenty of homeowners here, that means an edit bay or writing studio you can walk to before coffee. For others, it's a guest house for parents or an income unit earning what a Studio City address commands. Either way, it has to fit the street it sits on.
Athenian Builders Group is a licensed California general contractor (CSLB #1045030) that designs and builds ADUs across Studio City. One team carries the drawings, the LADBS permits, and the construction, with a fixed price in writing, a firm timeline, and a 2-year workmanship warranty. See our full ADU construction services.
Permits
Studio City is part of the City of Los Angeles, so ADU permits go through LADBS. We prepare the drawings, file the application, and manage every inspection through final approval.

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 Studio City.
Questions
Yes. We design and build detached ADUs, studios, and guest houses across Studio City, hillside lots included, and our own crews do the work.
Studio City is part of the City of Los Angeles, so LADBS issues the permits. We handle the whole process, application to final inspection.
Type and size drive the number. A garage conversion typically runs $100k–$180k, while a detached new-build lands between $250k–$450k. You approve a fixed, itemized price after a free on-site walkthrough.
Most of our ADUs finish in 3 to 5 months, plus LADBS review time before construction starts. You approve a firm timeline in writing before we break ground, so the schedule is never a guess.
