Get your free estimateFast, Reliable Home Addition Contractor Across Florence-Graham
Home additions in Florence-Graham don’t run on a City of Los Angeles clock. Almost all of this unincorporated pocket of South Los Angeles falls under LA County Building and Safety, which means the permit path, plan-check wait, and inspection sequence for your sunroom or second story run through a different desk than a job two blocks west across the city line. That distinction trips up a lot of contractors, and it’s the first thing we check before we ever quote a project here. If you’re planning a room addition, bump-out, or full second story in Florence-Graham, call (903) 568-7222 and we’ll scope it against the right jurisdiction from day one.
Why Benson ADU Builders Is Florence-Graham’s Preferred Home Addition Contractor Company
We stay current on what LA County Building and Safety is asking for on addition permits in unincorporated Florence-Graham, and that matters when the plan-checker comes back with comments on your lot’s setback or your existing slab. Our crews work regularly in the neighborhoods around East Florence Avenue, Compton Avenue, and Gage Avenue, and we’ve walked enough pre-1960 stucco houses here to know what’s waiting behind the drywall before the first wall comes down. When you call us for a Florence-Graham job, you get a written price before any work starts, not a verbal ballpark that drifts after demo day. Our owner, Troy Eastman, set this company up around one idea: a homeowner should never have to chase a contractor for a number, a schedule, or an answer. Every project carries our 365-Day Done Right Promise in writing, and a live person answers the phone around the clock. No voicemail loops, no “we’ll circle back Monday.”
Sunroom Addition in Florence-Graham
A Sunroom Addition in Florence-Graham is one of the most practical ways to add usable square footage on a narrow lot without the full cost and structural load of a second story. Most of the sunrooms we build here run between $45,000 and $85,000 depending on whether you’re doing a simple insulated patio enclosure or a conditioned year-round room with new electrical, HVAC tie-in, and a proper foundation. The real answer for your lot depends on what’s already there: many Florence-Graham yards have unpermitted concrete slabs and detached garages sitting close to the property line, which changes how we frame and where we can legally place the addition. In this part of the county, the plan-checker will look hard at setbacks and existing nonconforming structures, so we get the title history and plot plan sorted before we ever put a shovel in the ground.
How We Handle Old Slabs and Setbacks
A 1940s slab wasn’t poured to carry a conditioned addition. If you’re enclosing a patio or extending off the back of the house, we’ll often need to pour new footings or upgrade the existing pad before framing starts. The county wants that work permitted and inspected, and we pull the permits, schedule the inspections, and stand behind it.
Design That Reads Like the Original House
Most Florence-Graham homeowners don’t want a sunroom that looks stapled on. We finish exterior cladding with James Hardie siding options so the roofline and walls tie into the existing house, and we match the pitch and fascia detail instead of leaving a visible seam where old meets new.
Second Story Addition Contractor in Florence-Graham
A Second Story Addition Contractor in Florence-Graham is dealing with a different animal than a typical room addition: you’re lifting a roof, adding structural shear walls, and asking an older house to carry weight it was never designed for. A full second story over an existing 900-to-1,200-square-foot bungalow in Florence-Graham typically runs between $180,000 and $320,000. An over-the-garage addition, which skips some foundation work but adds its own framing and access challenges, usually lands between $130,000 and $220,000. The big variable on these older homes is the foundation: if the original slab or perimeter footing needs retrofitting to meet current seismic standards, that’s a real cost you’ll want in the written quote before work begins, not after the roof comes off.
Seismic and Structural Reality on Pre-1960 Homes
Many houses in Florence-Graham were built well before modern shear-wall and anchor-bolt requirements. A second story changes how the whole building resists lateral load, and the county’s plan reviewer will ask for calculations showing the existing walls and footings can do the job. We run those calcs up front, and if the answer is “no,” we price the retrofit instead of hoping the inspector won’t notice.
Where Do You Live During the Work?
You can usually stay on the first floor during most of a second-story addition, but there will be a stretch during roof removal and framing where the top of the house is open to weather. We stage the work to keep the disruption window as short as the schedule honestly allows, and we’ll walk you through exactly which weeks are loud, dusty, or off-limits.
Trusted Brands We Service in Florence-Graham
We’re authorized to build with Cover, Dvele, and Mighty Buildings, which means a Florence-Graham homeowner isn’t stuck with one take-it-or-leave-it product line. If your sunroom or addition leans prefab, we can give you a side-by-side on a Cover panelized system versus a Dvele factory-built module, including what each one costs, how it arrives, and how it handles the county’s plan-check process. For site-built work, we stock and source James Hardie cladding so exterior finishes hold up to South LA sun and the occasional heavy rain. You can research every one of those brands yourself before you ever commit to a quote. We’d rather you do.
Common Home Addition Contractor Problems We See in Florence-Graham Homes
- Unpermitted prior work that surfaces during demo. We regularly find enclosed patios, rear garage conversions, and added rooms that were never pulled through the county. When you touch a wall adjacent to that work, the inspector can require it to be brought current, and that adds scope and cost in writing, not as a surprise later.
- Undersized electrical service on older houses. A 60-amp or 100-amp panel from the 1950s won’t carry a new sunroom’s mini-split plus a second-story heat pump. If we know early, we price the panel upgrade into the original quote instead of hitting you with a change order after framing.
- Wrong-jurisdiction pricing from city-based contractors. A contractor who quotes your Florence-Graham addition on a City of Los Angeles permit timeline will likely miss a longer County plan-check queue and different inspection sequence. That’s a schedule problem and sometimes a budget problem when labor gets rescheduled.
- Slabs and footings that were never meant for a conditioned space. The original house may sit on a slab with no vapor barrier, no rebar documentation, and questionable depth. That affects how we tie new footings and whether the county will accept the existing slab as part of the new footprint.
Pricing for Home Addition Contractor in Florence-Graham, CA
A bump-out addition of 150 to 250 square feet in Florence-Graham typically runs $60,000 to $120,000. A sunroom lands between $45,000 and $85,000. A garage addition or conversion from an existing structure usually falls between $80,000 and $150,000.

Second-story work is the widest range at $180,000 to $320,000 for a full addition over the existing footprint.

FAQs About Home Addition Contractor in Florence-Graham
Almost all of Florence-Graham is unincorporated LA County, so your addition permit goes through County Building and Safety, not the City of Los Angeles. The county has its own plan-check queue, its own inspectors, and its own forms, and the timeline is generally longer than a city job. We handle that path for you, but it’s the first thing any honest contractor should confirm before quoting a schedule. Call (903) 568-7222 and we’ll verify your parcel’s jurisdiction in the first conversation.
Foundation retrofit work, panel capacity, and roof tie-in complexity drive most of the budget on a second-story addition in Florence-Graham. If the original footing needs seismic anchoring, that’s real money before framing starts. If the panel is undersized, that’s another line item. We write every one of those into the original price so you see it before you sign. For a full second story here, expect $180,000 to $320,000. For exact numbers on your house, get the free estimate.
A sunroom or single-room addition in unincorporated Florence-Graham typically takes four to seven months once you factor in County plan check, resubmittals, and sequenced inspections. A second story runs six to ten months depending on weather windows and inspector availability. Anyone promising a two-week addition in this jurisdiction is skipping steps you’ll pay for later. We give you a written calendar that matches the county’s actual process, not a sales timeline.
Yes, in most cases. We’ve converted unpermitted patio slabs and rear garage spaces into permitted sunrooms and accessory rooms in Florence-Graham, but the county will require the original structure to be brought to current code as part of the work. That can add structural fixes and electrical corrections to the project. We’ll inspect it, tell you what the county will likely ask for, and price the legalization and the new addition as one job instead of pretending the old work doesn’t exist.
You inspect with LA County Building and Safety inspectors, not City of Los Angeles inspectors. The county inspector will look at footings before we pour, framing after shear walls go up, electrical rough-in, insulation, and the final finished space. We schedule every inspection and stand on-site for each one. Call (903) 568-7222 for a free estimate, and we’ll map the whole inspection sequence for your specific project before any work starts.
