Accessory Dwelling Units (ADUs) represent one of the most significant residential construction opportunities in Los Angeles today. Since California passed landmark ADU legislation (AB 68, SB 13, AB 881), homeowners across Los Angeles County can now build secondary dwelling units on their property with streamlined permitting processes, reduced impact fees, and relaxed setback requirements. An ADU can serve as a rental unit, guest house, home office, in-law suite, or multi-generational living space — all while significantly increasing your property value.

At Home Remodeling Los Angeles, we specialize in three primary ADU types: garage conversions (transforming an existing attached or detached garage into a habitable unit), detached ADUs (new ground-up construction in your backyard), and Junior ADUs (JADUs) (converting existing space within your main home into a unit up to 500 sq ft). Each type has distinct zoning, building code, and utility connection requirements that our team navigates daily.

Our full-service ADU construction process includes: site feasibility analysis, architectural plans and structural engineering, Title 24 energy compliance calculations, LADBS permit applications, foundation work, framing, roofing, plumbing (including sewer lateral connections), electrical service (sub-panel or separate meter), HVAC installation, insulation, drywall, flooring, kitchen and bathroom buildout, and final inspection sign-off. We also coordinate utility connections with LADWP and SoCalGas.

ADU costs in Los Angeles typically range from $150,000-$350,000+ depending on size, whether it’s a conversion or new build, foundation requirements, and finish level. Garage conversions are generally the most cost-effective option since the existing structure provides the foundation, walls, and roof. Many homeowners offset construction costs through rental income, with LA-area ADUs commonly renting for $1,500-$3,500 per month depending on size and location.
