ADU Construction in Los Angeles
Design-build accessory dwelling units from initial permitting through final walkthrough, with a single licensed contractor accountable for the entire project.
Design-build ADUs from permit to final walkthrough.
An accessory dwelling unit adds rental income, multigenerational living space, or a dedicated home office to your property. FORZA CONSTRUCTION manages every stage of your ADU under one licensed contractor, so you have a single point of accountability from the first sketch to the final inspection.
Detached, attached & garage-conversion ADUs
We build new detached units, attached additions, and garage-to-ADU conversions, matching the structure and utility hookups to your lot, budget, and the current California ADU regulations.
Permitting handled for you
We prepare and submit plans through your local building department, track plan-check comments, and coordinate inspections, so you don't have to manage the process yourself.
Design-build, not design-then-hope
Because the same team designs and builds your ADU, drawings are grounded in construction reality from day one, which reduces costly change orders once framing starts.
Building ADUs across the San Fernando Valley & Westside.
We currently take on ADU projects in Studio City, Burbank, Beverly Hills, Pacific Palisades, Playa Vista, and the surrounding Greater Los Angeles area.
Common questions
How much does an ADU cost to build in Los Angeles?
Most detached ADUs in the LA area run from $250,000 to $450,000 depending on size, foundation type, and finish level, while garage or attached conversions typically start lower. We give every client a detailed, itemized estimate after the initial walkthrough so there are no surprise costs mid-build.
How long does the ADU permitting and construction process take?
Permitting through LA Department of Building and Safety typically takes 2-4 months depending on the plan check queue, and construction runs another 4-8 months for a detached unit. As your design-build contractor, we manage the permitting timeline directly so you're not stuck waiting on separate architects and contractors.
Can I rent out my ADU or use it for family?
Yes. Most homeowners we work with build ADUs either as long-term rental income, a place for aging parents or adult children, or a home office / studio. We help you plan the layout and utility connections around your intended use before permits are drawn.
Do I need a separate architect before hiring FORZA?
No. We run design-build ADU projects end to end, coordinating architectural drawings, structural engineering, permitting, and construction under one point of accountability, so the drawings actually match what gets built.
