ADU Construction for Calabasas Homeowners
Accessory dwelling units are one of the strongest returns available to Calabasas property owners. California state law now overrides most local barriers, and lots characterized by newer gated-community homes with strict HOA design review frequently have room for a detached unit, a garage conversion, or an attached addition.
We handle the full path: feasibility and setback review, architectural plans, structural engineering, submittal to the City of Calabasas Building & Safety Division, utility coordination, construction, and final sign-off. You get one contract and one point of contact instead of juggling designers, engineers and subs.

ADU Construction in Calabasas — FAQs
Can I build an ADU on my Calabasas property?
Most single-family and multifamily lots in Calabasas qualify under current California ADU law. We run a free feasibility check on setbacks, lot coverage and utilities before you spend anything on plans.
What does an ADU cost in Calabasas?
Budget roughly $200–$400 per square foot. A 600 sq ft detached ADU commonly totals $150,000–$250,000 including plans, permits and utilities. Garage conversions are usually less.
How long does the Calabasas ADU permit process take?
Plans and plan-check through the City of Calabasas Building & Safety Division generally take 3–6 months, then 4–8 months to build. Rules change — we confirm current requirements with the building department on every project.
Will an ADU increase my property value?
A permitted ADU adds both rentable income and appraised square footage. Actual value depends on the local rental market and appraisal method, so we recommend confirming with a local agent or appraiser.
