Sunroom construction in South Gate CA - a room you'll actually want to sit in

Tired of looking at a bare patio or an old deck? We build a sunroom on it that's comfortable enough to get used.

What goes into building a sunroom on my patio?

Sunroom construction in South Gate means building a real room onto the patio, deck or slab you already have, with windows, siding, a roof and basic wiring, so a spot you walk past every day becomes a room you sit in.

Most people who call us have a patio, deck or old porch they're tired of looking at, and we're based in South Gate and work in the cities around it, plus the county areas nearby. The price moves with the size of the room, the kind of glass, and whether you want a seasonal room or one heated and cooled like the rest of the house. The schedule turns mostly on the city's steps, since some projects need plans reviewed before anything gets built. I look at what the room will sit on before I put a number on paper, so the figure you get is for your house and not a guess from a chart.

What sunroom construction with us involves

I start by asking how you'll use the room, before we pick the glass or the layout, because a seasonal room and an extra living room are different jobs. A sunroom that runs apart from your home's heating and cooling isn't meant to be part of the living space, so if you're picturing a family room you can sit in all summer, say so up front and we plan for that. Then we check the slab, deck or wall the room ties into, frame the walls and roof, set the windows, put on the siding and roofing, run the basic wiring and clean up behind ourselves. A room that's too hot or leaks is just an expensive porch, so most of the thinking happens before the first board goes up.

Not every job starts from bare concrete. If you already have a sunroom that bakes in the afternoon or never gets used, sunroom remodeling can often fix it without starting over. And if what you really want is shade and no mosquitoes, screen room installation gives you a cheaper room, and I'd rather talk you into the cheaper room than the wrong one.

Sunroom construction in South Gate and what the city asks for

In South Gate, permits go through the city's Building and Safety Division, which says a permit is typically required for any construction project, though its list of examples doesn't name sunrooms, so we check with the city about your job instead of guessing. Some projects need the Planning Division to review a set of plans first, with its own fees, and that approval comes before anything goes to Building and Safety. A project valued over $50,000.00, or one adding more than 800 square feet of new construction, also needs Public Works review, and the city sets that value from the scope of work. If the room means opening a bearing wall, the kind that holds up part of the house, or changing the roof structure, the city requires South Coast Air Quality Management approval along with an asbestos survey. We find out which of these steps your project hits and take care of them, and I tell you early if plans or reviews have to come first.

Summers here get hot, and a glass room on a west-facing patio can bake by mid-afternoon, so we think about which way the room faces and how much glass goes overhead before we settle the layout. We see the same small backyards and concrete patios on jobs in Lynwood and Huntington Park, and the same rule holds there. Plan for the heat first.

How sunroom construction works

  1. Call or send the form

    You call or send the form and we set a time for me to come out. Evenings and weekends work too, since our phones are answered late.

  2. I come out and look

    I look at what the room will sit on and ask how you plan to use it. That answer shapes the glass, the layout and the price more than anything else.

  3. Get a written estimate

    You get a written estimate that says what's in it and what isn't, so you can line it up against anyone else's. If the number's higher than you hoped, I'll tell you which choices bring it down.

  4. Permits, building, then a walk-through

    We take care of the permit steps and then build the room. I walk the finished room with you before we call it done.

Questions before you build a sunroom

What does a sunroom cost in the Los Angeles area?

A three-season sunroom built on an existing patio, deck or slab in the Los Angeles area usually costs about $110 to $160 per square foot. One cost guide's figure for that kind of room leaves out insulation, plumbing, permits and heating and cooling equipment, so ask whether each quote includes them. Our estimate spells out whether insulation, heating and cooling, and permit work are in it.

Do I need a permit to build a sunroom in South Gate?

Plan on needing one, since South Gate says a permit is typically required for any construction project. The city's list of examples doesn't name sunrooms, so we confirm with Building and Safety for your address and handle the steps, including the plan and review steps covered above.

What is the best way to choose glass for a sunroom?

For most rooms, go with upright glass walls. They cost less and are easier to install and insulate than glass that slopes into the roof, and they leak, fog and break less often. Sloped glass gives you more sky, but you pay for it up front and again in repairs.

Who can legally build a sunroom in California?

A contractor licensed by the California Contractors State License Board. The state requires that license when a job needs a building permit, uses any extra workers, or costs $1,000 or more in labor and materials. A sunroom crosses that last line before the glass even shows up.

Does a sunroom addition need energy paperwork in California?

It often does. California's energy guidance says compliance documents have to be registered for all newly built homes, most additions and many alterations, so ask early whether your room counts as an addition. It's easier to settle before plans go to the city than after.

How do I take care of a sunroom after it's built?

Check the roof and gutters once a year. One sunroom maker's guide suggests a yearly inspection of both, and it's a small job that catches a clogged gutter before it turns into a wet floor.
