Adding an ADU or home addition in Florence-Graham comes down to three things: lot shape, soil, and older housing stock. We’re Sutton ADU Builders, and we handle all three. Most Florence-Graham lots are compact and rectangular, which means setbacks (the required gap between your new structure and the property line) drive the design more than anything else. Whether you’re planning a detached ADU behind a 1920s bungalow or converting a garage off Compton Avenue, the plan has to fit the actual lot, not a brochure. Call (472) 248-8213 and we’ll tell you what’s possible on yours.
Why Florence-Graham Homes Are Different
Florence-Graham’s housing stock skews older, with a high share of single-story homes built between the 1920s and 1950s. That means foundation work is rarely optional. Many lots sit on soil that shifts with the seasons, and we see more slab settling here than in newer parts of the county. Before we quote an ADU or addition, we look at how the existing structure was built, because tying new framing to a 1950s foundation is different from working on a 1990s slab.
Lot sizes also run tight. A detached ADU has to respect side and rear setbacks, and in Florence-Graham, those setback measurements often decide whether you get a 600-square-foot unit or a 450-square-foot one. We’ve learned to work within those inches. Climate matters too: summer heat sends roof loads up and fall brings occasional heavy rain, so drainage and roof pitch get extra attention here. Homeowners near the Florence-Graham border with Huntington Park often ask about HOA rules; most of the area is not HOA-governed, but Los Angeles County permit rules apply everywhere, and we pull permits on every job.
Our Main Florence-Graham Services
These are the three jobs Florence-Graham homeowners call us about most. Each has its own page with pricing, timelines, and what to expect on-site in Florence-Graham.
Home Addition Contractor in Florence-Graham
A home addition in Florence-Graham usually means extending the back of the house or adding a second story over a single-story frame home. The structural tie-in is the critical step. Older homes here were not engineered for vertical loads on top, so a second-story addition often requires reinforcing the existing foundation and walls first. We handle that in-house and write it into the price before we start. If you’re adding a bedroom or family room, Home Addition Contractor in Florence-Graham is the page to read.
ADU Builders in Florence-Graham
Detached ADUs in Florence-Graham work best when the design respects the narrow side yards. A unit that’s 16 feet wide instead of 18 can mean the difference between a permit that moves quickly and one that bogs down in variance requests. We build stick-frame ADUs on site and also install prefab units from Abodu and Cover when the lot and budget favor factory construction. For a full walk-through of what’s involved here, see ADU Builders in Florence-Graham.
Room Addition Contractor in Florence-Graham
Room additions are the most common single call we get from Florence-Graham: a new bedroom, a home office, or a larger kitchen. On older homes, we often find knob-and-tube wiring or cast-iron drain lines that have to be replaced before the addition can tie in. That’s normal for this area and it’s always listed in your written quote before work begins. Details and pricing are on the Room Addition Contractor in Florence-Graham page.

Brands We Service in Florence-Graham
