Sunroom contractor in Florence-Graham, CA - rooms built on the patio you already have
South Gate Sunrooms & Patios is a sunroom contractor based in South Gate that builds sunrooms, patio enclosures and patio covers in Florence-Graham, mostly on the slabs, decks and back porches these houses already have.

Close-set family homes across Florence-Graham
Florence-Graham, which county pages call Florence-Firestone, sits south of downtown Los Angeles with the City of Los Angeles around it on three sides. To the east are Huntington Park, South Gate and Walnut Park, so it's a short drive from where we're based.
Most neighborhoods here are single-family houses and smaller buildings, and the bigger apartment buildings are out on the main streets and corners. The houses we get called to usually have a slab, a wood deck or an old back porch the owner is tired of looking at, and that's where the room goes, because there's rarely space to build out anywhere else on the lot.
Permits and licenses in unincorporated Florence-Graham
Florence-Graham isn't its own city, so Los Angeles County acts as the local government, and for a sunroom that means LA County Public Works issues the permit, since its list covers additions, alterations and patios. The permit comes before the build, so the county's process sets when we can start, not my calendar. Before you hire anyone, check that they hold a California contractor license from the Contractors State License Board. The county Treasurer and Tax Collector runs a separate business license program, which covers a set list of business activities in unincorporated areas like this one.
I check which office covers your address first, the same as I do on a job in Downey or back home in South Gate, because the office decides the paperwork and the wait. Then we take care of the permit steps and tell you early if plans or a review come first. The price mostly moves with what the room sits on, how big it is, screen or glass, a three season room or one you use year round, and whether it needs wiring. You get your own figure in a written estimate after I've looked at the slab, deck or wall the room ties into.
Services in Florence-Graham, CA
Patio enclosures
A lot of backyards here come down to a slab and a fence, so a patio enclosure is often the most usable room for the money. We close it in with screen or glass walls fitted to the slab you have, after checking it's level and sound enough to hold them.
Patio-to-sunroom conversion
When a patio cover is already up and solid, turning it into a real room is the next thing Florence-Graham owners usually ask about. We check whether the cover can carry walls and glass, and if it can't, I tell you before you find out the expensive way.
Three season sunrooms
On a close-set lot, a three season room gives you a covered, bug-free spot without building a fully finished room. We build it lighter, with less insulation than a year-round room, which is fine if you'll mostly use it when the weather's good.
Four season sunrooms
If the room is going to be an office, a bedroom or the place everyone eats, it has to work like the rest of the house. We build these insulated, with proper glass and electrical, and tie them into the house like any other addition.
Patio cover installation
Plenty of yards here just need shade over the slab, and a patio cover does that for a lot less than a room. If a cover is what you'll actually use, I'll say so at the estimate.
Sunroom remodeling
Older enclosed porches and patio rooms turn up on these streets often, and the usual trouble is a leak where the room meets the house or glass that's fogged. We replace the roof, panels or glass that's failing and keep the frame if it's still sound.
What tight Florence-Graham lots ask of a sunroom
Florence-Graham is one of the densest communities in the county, so a new room usually sits a few steps from the fence and the house next door. We plan the roof slope and gutters so rainwater goes where you want it and not over the fence, and we think about which walls get glass so you're not sitting in a fishbowl.
The other thing we look hard at is what the room ties into. An old slab may have cracked or settled, a wood deck can be soft at the posts, and stucco has to be opened up cleanly where the room meets the wall. I'd rather tell you at the estimate that the slab needs work than build a nice room on a bad base.

We reply within one business day, and there's no obligation. I come out to your Florence-Graham house myself, look at the slab, deck or wall the room will tie into, and ask how you plan to use it. You get a written estimate that says what's in it and what isn't.
Working with us in Florence-Graham
Call or send the form
You call (213) 376-0861 or use the form, and we set a time for me to come out. It helps if you're home, because how you'll use the room matters as much as the measurements.
Look at the base together
I check the slab, deck or wall the room will sit on and tie into, and we talk through what kind of room fits. You get a written estimate that spells out what's included and what isn't, so there's no surprise line later.
We handle the permit steps
We find out which office covers your address and take care of the permit steps with them. If the county wants plan check first, which is an expert review of the plans against building and safety standards, I tell you early because it comes before we can start.
Build and walk the room
Our own crew builds the room, and I check on the work as it goes up. When it's finished, I walk the room with you before we call the job done.
Florence-Graham sunroom questions answered
How do I find out what permits my sunroom needs in Florence-Graham?
Contact the local office shown for your address in LA County Public Works' Service Locator, by phone or email, which is how the county says to ask what a project requires. A sunroom tied to the house counts as an addition, and the county's list names additions and patios among the work it permits. We make that call for you as part of the job.
Does replacing the windows in my sunroom need a permit in Florence-Graham?
It can, because the county's permit list names window and door changeouts among its remodel examples. Ask the county before the old glass comes out, and on our jobs we check that before we put the swap in an estimate.
When does a contractor need a state license in California?
A contractor needs a license from the Contractors State License Board for any job that needs a building permit, uses extra workers or comes to $1,000 or more in labor and materials. The small-job exemption went from $500 to $1,000, and it only covers work with no permit and no employees, so a permitted sunroom doesn't fit it. We're licensed and fully insured.
When is the first inspection due after getting a permit in LA County?
County guidance says to request the first inspection within 12 months of getting the permit. After that, inspections every 6 months keep the permit active, so we book them as the room goes up instead of letting the permit sit.
How much does a sunroom cost in Florence-Graham?
It depends mostly on what the room sits on, how big it is and what kind of room it is, and you get your own figure in a written estimate after I see the site. A screened enclosure on a sound slab costs far less than an insulated room with glass and wiring, and a slab that needs repair adds to either. I'd rather talk you into the cheaper room you'll use than the bigger one you won't.
How do I check if my Florence-Graham home is in an earthquake hazard zone?
Type your address into the state's EQ Zapp tool, and it shows whether that property sits in a mapped earthquake hazard zone. Each result covers only the address you search, so check your own lot instead of going by a neighbor's, and tell me what it showed when I come out.
