ADU Construction Los Angeles — Lux Builders & Remodeling
Lux Builders & Remodeling Inc. is a licensed Los Angeles ADU contractor specializing in the design, permitting, and construction of Accessory Dwelling Units across the South Bay and greater Los Angeles County. Under current California law, most single-family lots in our service area are eligible for an ADU — and we handle the entire process from design through a finished, permitted unit.
What Is an ADU?
An Accessory Dwelling Unit (ADU) is a secondary housing unit on a single-family residential property. ADUs can be detached (a separate structure on the lot), attached (connected to the main house), or converted from existing space such as a garage. California’s ADU laws, significantly expanded since 2020, now make it easier and faster than ever to build an ADU on most residential lots in Los Angeles County.
A Junior ADU (JADU) is a smaller unit (up to 500 sq ft) created within the existing footprint of the primary residence, such as from a bedroom or attached garage conversion.

ADU Timeline and Cost
A typical detached ADU in Los Angeles takes 3 to 5 months to build from permit approval, depending on size, city, and design complexity. A garage conversion ADU is generally faster — often 2 to 4 months.
ADU construction costs in Los Angeles typically range from $150,000 to $400,000+ for a detached unit, depending on size, site conditions, and finish level. Garage conversion ADUs can cost less. We provide a detailed fixed-price estimate after your free consultation so there are no surprises.
ADU Benefits for LA Homeowners
ADUs are one of the best investments a Los Angeles homeowner can make. A completed ADU can generate rental income of $2,000–$5,000+ per month in most South Bay and Westside neighborhoods, helping offset your mortgage. ADUs also add significant value to your property and can house family members while maintaining privacy.
