ADU Company in Florence-Graham, CA
Florence-Graham is an unincorporated Los Angeles County community, which means every accessory dwelling unit (ADU – a self-contained living space with its own kitchen, bath, and entrance on your existing lot), garage conversion, and home addition here is permitted through LA County’s Department of Regional Planning and Building & Safety, not the City of LA. That single fact trips up more Florence-Graham homeowners than any other, and it’s the first thing we walk through on every estimate. The housing stock here – mostly 1940s to 1960s stucco bungalows on 4,000 to 6,000 sq ft lots – is well suited to ADU work, but the electrical and plumbing upgrades those old homes need catch people off guard.

Why Florence-Graham Homes Are Different
Florence-Graham parcels sit outside the City of LA’s online permit portal, so homeowners who pull City forms lose weeks before they learn they need the County’s separate ePlans system and zoning lookups through the LA County GIS portal. We handle that paperwork correctly the first time. The homes themselves create a second layer of scope: a detached single-car garage from the 1950s often carries 60-amp electrical service and galvanized supply plumbing, both of which need upgrades before the County will sign off on an ADU permit. Owners routinely underestimate that cost, which is why we write the complete price before any work begins. Florence-Graham also sits squarely in South LA’s urban heat island, where dense hardscape pushes summer temperatures several degrees above coastal neighborhoods. That means cross-ventilation and proper insulation are not add-ons here; they are what makes the space livable from June through October.
Our Main Florence-Graham Services
Most Florence-Graham homeowners call us about one of three projects: building an ADU from the ground up, converting an existing garage into living space, or adding square footage to the main house. Each has its own permitting path through LA County.
Home Addition Contractor in Florence-Graham
A home addition in Florence-Graham often means extending off the back of a 1940s bungalow, which brings the existing foundation, roof line, and electrical panel into the permit conversation along with the new square footage. We have walked dozens of these lots and know where the County inspectors look first. The written price you get includes the foundation work, framing, roofing tie-in, and the panel upgrade if the home still runs on a 60-amp service. You will not get a change order at the door.

Garage Conversion Contractor in Florence-Graham
Florence-Graham’s detached single-car garages are popular conversion candidates, but the old electrical and galvanized plumbing inside them mean the real cost is rarely just framing and drywall. We price the full scope up front: panel upgrade, copper repipe where the County requires it, insulation suited to South LA heat, and the finished living space. This is an ADU conversion by another name, and it permits through LA County, not the City. Garage Conversion Contractor in Florence-Graham

ADU Builders in Florence-Graham
A detached ADU in Florence-Graham gives you a compact second home in the back third of the lot, but the unincorporated County process is different from LA City and the wrong form can stall the project for weeks. We pull the right permits through the County’s ePlans system and match the unit – stick-built or prefab from brands like Abodu and Cover – to your lot dimensions, setback rules, and budget. Every quote is a written, line-item price. ADU Builders in Florence-Graham

FAQs About ADU Company in Florence-Graham
Florence-Graham is unincorporated, so all ADU, garage conversion, and home addition permits go through Los Angeles County Department of Regional Planning and Building & Safety, not the City of LA. Using City forms will stall the project. Call (254) 602-5618 and we will confirm the right path before you file anything.

- Marcus Beaumont"I was nervous about adding on but they walked me through every step and every cost before we started. No surprise change orders halfway through like I'd heard horror stories about."
