Why Penhallow Remodeling Is Florence-Graham’s Preferred General Contractor Company
Working in Florence-Graham is different from working in an incorporated city like Huntington Park or South Gate. We know the permit workflow backward and forward, because we run county permits through LA County Building and Safety’s Altadena or Avalon district office, not a city hall counter. That sounds like a paperwork detail, but it’s the difference between framing on week two and waiting on a jurisdiction correction for a month.
Trevor Nash runs our crew, and the standard he sets is simple: a written price before any work starts, a written guarantee on every job, and a 365-Day Done Right Promise that says if something fails during the guarantee period, we come back and fix it at no charge. Every technician who walks onto a Florence-Graham job site is background-checked, uniformed, and has the same standard: leave the place cleaner than we found it.
Florence-Graham homeowners haven’t always gotten that from contractors. We hear the stories. The verbal estimate that doubled after demo. The crew that disappeared for two weeks. The tile that cracked six weeks after the last check cleared. We built our process around the assumption that you’ve been burned before and you won’t tolerate it twice.
Residential General Contractor in Florence-Graham
Residential General Contractor work in Florence-Graham almost always starts with these pre-renovation realities: wood-frame houses and duplexes from the 1940s through 1960s, original electrical panels, galvanized supply lines, and stucco that may contain asbestos. A kitchen remodel here runs $14,000 to $45,000. A bathroom remodel runs $9,000 to $28,000. Before any of that starts, hazmat testing and system replacement often become part of the scope. We identify that up front, in writing, so the number doesn’t move on you later.
Whole-Home and System Upgrades
Older Florence-Graham homes frequently need panel upgrades, re-piping, and structural work tied into an otherwise cosmetic remodel. The county won’t issue final sign-off on an ADU if the existing 100-amp service can’t carry the added load. We scope these items in the plan set before the first inspection.
Room Additions and ADUs
Adding square footage in Florence-Graham means county plan check, which requires a grading and drainage sheet if your lot drains toward an alley or the sidewalk. A home addition runs $45,000 to $130,000. An ADU runs $90,000 to $220,000. We don’t quote those numbers until we’ve verified setbacks to the county’s line.
Hire a General Contractor in Florence-Graham
When you hire a General Contractor in Florence-Graham, you’re hiring someone who manages the permit process, coordinates inspectors, schedules material deliveries, and keeps subs accountable. The county workflow here is entirely separate from neighboring municipalities. Contractors who pull permits at the City of LA counter or Huntington Park City Hall by mistake have to withdraw and refile through LACBS, which costs weeks. We file the right jurisdiction the first time.
What a Scoped Quote Includes
Before we quote an acreage or open-lot job, we verify utility setbacks, sewage or septic placement, and equipment access paths. Long material hauls off Gage Avenue or Central Avenue change the price. We pass the real number through the first time instead of surprising you at the rough-in stage.
Inspections and County Sign-Off
Inspections in Florence-Graham are scheduled through the county system, not a municipal department. We coordinate that calendar for you and show up for every visit. The rough-in inspection on a detached ADU behind a 1950s wood-frame house off Gage Avenue passed on the first county visit because we staked the setbacks before framing started.
Trusted Brands We Service in Florence-Graham
We install products from brands our Florence-Graham customers recognize and trust: Cambria and Silestone countertops, KraftMaid and Wellborn cabinetry, Kohler and Moen fixtures, and James Hardie siding. When modular or prefabricated options make sense for an ADU or a garage conversion on a tight Florence-Graham lot, we’ve worked with ADU providers like Abodu and Cover. The products behind our guarantee are as solid as the promise itself, which is the point of the 365-Day Done Right Promise in the first place.
Common General Contractor Problems We See in Florence-Graham Homes
- Wrong-jurisdiction permit filings: We’ve seen contractors file at Huntington Park or South Gate counters, then discover they’re in unincorporated LA County after demo already started. Withdrawing and refiling through LACBS costs weeks and money.
- Missing grading and drainage sheets: Flat interior lots in the LA Basin drain toward alleys or streets. The county plan check kicks back projects that skip the grading sheet, so we include it from the start.
- Galvanized supply plumbing and original electrical: Most Florence-Graham homes built before 1960 have galvanized lines that are corroded internally and panels that can’t handle modern load. We test and scope replacement before quoting, so it’s not a surprise change order.
- Asbestos in stucco and floor tile: Pre-1978 construction here commonly contains asbestos-containing material. We bring in hazmat testing and follow county abatement protocol before any disturbance.

FAQs About General Contractor in Florence-Graham
Florence-Graham is unincorporated Los Angeles County, so all construction permits, including outbuilding, ADU, and grading permits, are pulled through LA County Building and Safety’s Altadena or Avalon district office, not any city hall. Contractors who mistakenly file at Huntington Park or South Gate have to withdraw and refile, which costs weeks. We file the correct jurisdiction every time. Call (936) 259-2607 for an exact quote, estimates are free.
Yes. An ADU or detached shop building requires county plan check that includes a grading and drainage sheet, septic and utility setback staking, and an outbuilding separation review.

We include all of that in the written price before work starts. Call (936) 259-2607 to talk through your lot.
You should have a written price, a written guarantee, and a defined arrival window, along with the scope of work, permit responsibility, and a payment schedule. That’s what we hand you before any work starts. If a contractor won’t put the number in writing, do not let them start. Call (936) 259-2607 and we’ll walk you through a sample contract.
A home addition in Florence-Graham typically runs $45,000 to $130,000, and an ADU runs $90,000 to $220,000.
