Fast, Reliable General Contractor Across Florence-Graham
Hiring a General Contractor in Florence-Graham means navigating county permitting, old housing stock, and lots that were platted decades before anyone imagined an ADU. Most homes here were built between the 1940s and 1970s. That means original cast-iron plumbing, undersized electrical panels, and foundations that have shifted through sixty years of hot, dry summers and occasional pounding winter rains. You need a contractor who knows what lives behind those stucco walls before the first hammer swings. Mason Remodeling Co Los Angeles serves Florence-Graham with written pricing on every project, background-checked crews you can identify by name and photo, and a 365-Day Done Right Promise on the work. Call (213) 632-5711 to schedule your free estimate.
Why Mason Remodeling Co Los Angeles Is Florence-Graham’s Preferred General Contractor Company

Florence-Graham sits in an unincorporated pocket of LA County. That one fact changes how every permit is pulled, every setback is measured, and every quote is scoped. We have worked through county septic reviews, grading plans, and retrofit requirements on streets like Stanford Avenue and beyond. Our reputation here comes from doing the hard part first: figuring out what the county will actually approve before you spend money on plans.
Every crew member who arrives at a Florence-Graham home is background-checked, identity-verified, and introduced to you by name and photo before the visit. That is the Threshold Standard, and it is not optional on our jobs. We put your written price in your hands before any work starts. No verbal estimate that grows later. No surprise invoice at the end. Just a real number, in writing, with the scope spelled out.
When you call (213) 632-5711, a live person answers. Day or night, weekend or holiday. No phone tree, no voicemail loop, no waiting until Monday. That matters more than people realize until they have a burst pipe behind a kitchen wall at 9 p.m. on a Saturday.
Styles & brands we work with







Licensed General Contractor in Florence-Graham
A Licensed General Contractor in Florence-Graham handles the full scope of a project: permits, demolition, framing, plumbing, electrical, drywall, finishes, and the final county inspection. Because this is unincorporated LA County and not the city of Los Angeles, the permit process runs through county departments with their own rules on septic placement, well setbacks, and grading. We manage that entire chain for you, from first county submittal to final sign-off.
What does that cost here? A home addition in Florence-Graham typically runs $45,000 to $130,000. A kitchen remodel lands between $14,000 and $45,000. A bathroom remodel runs $9,000 to $28,000. These are real market ranges for this area, not national averages. The final number on your written quote depends on what we find when we open the walls.
Permit and Inspection Handling
Unincorporated Florence-Graham reports to LA County Building and Safety, not LA City. That means septic and well setback reviews can add weeks to the scoping phase. We budget that time into the schedule and tell you about it before you commit to a start date. We pull the permits, schedule the inspections, and stand next to the inspector when they walk the job.
Unpermitted Work and Code Corrections
Many Florence-Graham homes have detached garages that someone converted into living space decades ago without pulling a permit. When we come in for an addition or ADU, county inspectors will find that unpermitted work. We bring it to code first, then build what you actually asked for. It adds cost, but ignoring it means failing the final inspection.
Residential General Contractor in Florence-Graham

A Residential General Contractor in Florence-Graham works on the home you live in: additions, remodels, garage conversions, and ADUs. Unlike a commercial contractor, we build around your family’s schedule, protect the parts of the house you are not remodeling, and keep the dust and noise contained as much as the job allows. We know the housing stock here: modest single-story stucco and wood-frame homes on small lots, many with detached garages and limited side setbacks.
Expect a bathroom remodel in Florence-Graham to run $9,000 to $28,000, with smaller baths starting around $5,000 to $12,000. A garage conversion into living space runs $30,000 to $80,000. An ADU, depending on site conditions, runs $90,000 to $220,000. These are Florence-Graham numbers, not generic statewide figures. Call (213) 632-5711 and we will scope your specific lot.
Build on Acreage and Small Lots Alike
Florence-Graham lots are dense and small, but some parcels still carry open space or oversized rear yards. On an open lot, grading and drainage become the first order of business before footings go in. On a tight lot, material staging and equipment access guide the entire build sequence. We scope both before quoting.
Septic, Wells, and Setbacks
County rules on septic and well setbacks are stricter than anything city homeowners deal with. A 100-foot septic setback from a shared well can force a drain line to be re-routed, which changes the grading plan, which changes the price. We map all of that before we hand you a written number, not after the first inspection fails.
Trusted Brands We Service in Florence-Graham
When a Florence-Graham project calls for a manufactured ADU or panelized structure, we work with names like Abodu, Cover, and Dvele. These are engineered systems built to California code, and they can shorten the on-site build time significantly compared to stick framing. For clients who want a fully custom ADU or addition, we bring the same framing and finish crews we use on whole-home remodels. Either path gets your written price before work starts, your permit package handled, and the 365-Day Done Right Promise behind the finished product.

AfterCommon General Contractor Problems We See in Florence-Graham Homes
- Unpermitted garage conversions. Detached garages from the 1950s and 1960s often got turned into bedrooms or rental units with no permit and no inspection. We bring the structure, electrical, and plumbing up to code before the county will sign off on anything new.
- Shifting foundations and cracked stucco. The clay soil here expands and contracts through hot, dry summers and heavy winter rains. That movement shows up as stair-step cracks in stucco and doors that no longer latch. Proper drainage and foundation assessment come before cosmetic repairs.
- Original plumbing and electrical. Many Florence-Graham homes still run on galvanized pipe and 60-amp panels from the 1940s. A remodel that opens a wall for tile often uncovers plumbing that has to be replaced. We scope for that in the written quote, not as a change order later.
- County permitting surprises. A homeowner who assumes city of Los Angeles rules apply will hit a wall when LA County’s septic and grading reviews kick in after plans are already paid for. We start with the county review, not end with it.

FAQs About General Contractor in Florence-Graham
Unincorporated Florence-Graham pulls permits through LA County, not the city of Los Angeles, which means septic and well setback reviews, grading plan approvals, and county-specific retrofit requirements all apply. This adds weeks to scoping and can change what you are allowed to build. We handle the county process start to finish, so you are not guessing. Call (213) 632-5711 and we will walk you through what your lot can actually do.
Setbacks in unincorporated Florence-Graham depend on your specific lot size, zoning, and whether a well or septic system exists on the parcel. County rules can require 100 feet of separation from a shared well for any drain line. We verify setbacks before quoting so your workshop plan does not die in plan check. Call (213) 632-5711 for a site-specific answer.
Yes. We regularly bring unpermitted garage conversions up to code before adding an ADU on Florence-Graham properties. That means correcting electrical, plumbing, structural, and fire-safety issues to satisfy the county inspector. On Stanford Avenue, our crew took a 1970s unpermitted garage shell with old knob-and-tube wiring and turned it into a legal one-bedroom unit with proper drainage and final county sign-off. Call (213) 632-5711 and we will assess yours.
We stage materials before demolition starts and schedule deliveries in a sequence that fits your street and driveway. Florence-Graham’s small lots leave little room for staging, so we plan haul routes from county-approved lumber yards ahead of time to keep the crew working and the draw schedule on track. That planning is built into our written quote, not an afterthought. Call (213) 632-5711 to scope your lot.
Open lots in Florence-Graham often have poor positive drainage, which means water runs toward the foundation instead of away from it. The clay soil here also moves through dry and wet seasons, so we grade and compact before pouring footings, and we design drainage that handles heavy winter rains without pooling against the structure. A structural engineer certifies the grading plan for county review when setbacks require it. Call (213) 632-5711 for a free look at your lot.
