ADU Company in Los Angeles, CA
Los Angeles is the largest ADU market in the United States, and the work here looks different than anywhere else. We’re Lodgewick ADU Builders, and we focus on garage conversions, new detached ADUs, and home additions across Los Angeles. The city’s pre-approved LADBS Standard Plan Program means a permitted project can go from signed contract to shovel-ready in as little as two to four weeks, but only if your contractor knows how to navigate it. That knowledge, paired with LA’s hillside fire zones and seismic requirements, is what separates a smooth build from a stalled one. Call us at (254) 602-5618 to talk through your lot.
Why Los Angeles Homes Are Different
Los Angeles was largely built out between the 1940s and 1970s, and that housing stock is tailor-made for ADUs. Detached two-car garages sit behind single-family tract homes across the San Fernando Valley, South LA, and the Eastside. Those garages, often accessed by alleys, convert cleanly into accessory dwelling units without touching the main house. In older neighborhoods like Highland Park, Silver Lake, and Jefferson Park, the Craftsman bungalows from the 1920s through 1940s sit on deeper lots with rear yards that can hold a new detached ADU alongside a converted garage.
But two local realities change the math. First, large sections of the Hollywood Hills, Laurel Canyon, Tarzana, and Chatsworth fall inside Very High Fire Hazard Severity Zones. ADUs there must meet ember-resistant vent standards, use ignition-resistant exterior materials, and maintain defensible-space setbacks. Second, Los Angeles sits in Seismic Zone 4, so new detached ADUs require engineered foundations, and hillside parcels frequently trigger soils reports before a permit is issued. Flatland garage conversions in the Valley are typically the most straightforward projects; hillside new construction is the most involved.
Our Main Los Angeles Services
Most Los Angeles homeowners come to us for one of two things: adding square footage to the main house, or building a separate unit on the lot. Each service has its own dedicated page with full pricing and detail.
Home Addition Contractor in Los Angeles
Home additions in Los Angeles often mean expanding a post-war tract home’s footprint or adding a second story to a Craftsman bungalow. We handle engineered foundations, seismic retrofitting where required, and full interior finish work. Because so many LA additions touch hillside lots, we coordinate soils reports and LADBS plan checks early so the permit process doesn’t stall. See Home Addition Contractor in Los Angeles for line-item pricing and what to expect from start to finish.

Garage Conversion Contractor in Los Angeles
A detached garage conversion is the most common ADU project in Los Angeles, and for good reason. The structure already exists, the foundation is usually adequate for a living space, and alley access means crews can work without disrupting the main house. We handle electrical panel upgrades, plumbing tie-ins, insulation, and the fire-rated separation LADBS requires when the garage shares a wall with the primary residence. Garage Conversion Contractor in Los Angeles covers the full scope and cost breakdown.

ADU Builders in Los Angeles
For lots where a garage conversion isn’t the right fit, a new detached ADU is often the answer. We build stick-built and panelized units, and we match prefab manufacturers like Abodu and Dvele to lots where factory construction makes sense. Los Angeles permits move faster when the design fits LADBS’s pre-approved Standard Plan library, and we know which plans fit which setbacks. ADU Builders in Los Angeles explains the difference between builder types and what each costs.
