What is an all season room, and do you need one?

We build all season rooms in South Gate, CA as real rooms of the house. They tie into your home with insulation, wiring and heating and cooling, so the space works like part of the house and not like a closed-in patio.

Most calls start with a patio, deck or old porch you're tired of looking at, and the question is how much room you actually need. The price moves with the size of the room, the materials and glass, and whether it needs a new foundation or can use what's already there. The schedule usually turns on the permit and any city reviews the room's size or value brings on, which I cover below. Your own number comes from the written estimate, after I've looked at the slab, deck or wall the room ties into.

How we build an all season room

An all season room works like part of the house, so we plan the insulation, wiring and heating and cooling as one job instead of tacking them on at the end. I start with what the room sits on, because the slab, deck or wall it ties into decides whether we can build on it or need to pour a new foundation. Then our crew frames the room and ties it into the house, insulates the walls and roof, sets insulated glass, runs the wiring and puts in the heating and cooling. I'd rather talk you into the cheaper room than the wrong one, so if a three season room would do what you need for less, I'll tell you straight.

Sometimes the room you want is a little different. If you mostly want a covered patio closed in and don't need it heated and cooled like the house, an enclosed patio room usually costs less to build. If you want glass overhead as well as on the walls, that's solarium installation, and we'll talk through how much sun you really want in the room before you commit to it.

All season rooms in South Gate and the permit steps that come with them

In South Gate, permits go through the city's Building and Safety office, which says a permit is typically required for any home improvement or construction project. Its list names re-roofing and doesn't name all season rooms, so we don't treat your job as settled until we've asked the city about your address and your plan. A room's size, value and connection to the house can bring on more steps. When the city's Planning Division reviews a project's architectural plans, fees apply, and Planning has to approve before anything goes to Building and Safety. Projects valued over $50,000 or over 800 square feet of new construction also need Public Works review, additions of 500 square feet or more carry school fees, and the city wants air quality district approval when a project disturbs a bearing wall, one that holds up the roof, or the roof structure itself. We take care of the permit steps and tell you early if plans or reviews have to come first, because those can set the schedule more than the building does.

Most of what we see here are single-story houses with a slab patio or a wood deck out back and a roofline the new room has to meet cleanly. We're based in South Gate and work in the cities around it plus the county areas nearby, and we run into the same kinds of back patios on jobs in Lynwood and Downey. If you're not sure we come out your way, call and ask.

How an all season room gets built

  1. Call and set up a visit

    Call (213) 376-0861 or send the form, and I'll come out to look at what the room will sit on. I'll ask how you plan to use it, because that decides how much insulation and heating and cooling it needs.

  2. Get a written estimate

    You get a written estimate that says what's in it and what isn't, so wiring, heating and cooling or foundation work don't show up later as a surprise. That's your number for this room, not a ballpark.

  3. Clear permits, then build

    We take care of the permit steps with whichever office handles your address. Once the permit is in hand, our own crew builds the room.

  4. Walk the finished room together

    I walk the finished room with you before we call it done, opening the windows, running the heating and cooling and looking at where the room meets the house. If something isn't right, that's the time to tell me.

Questions before you book an all season room

How much does an all season room cost in South Gate?

Across the US, adding a four-season sunroom usually costs about $20,000 to $80,000 per room. That's a national figure from a cost guide, not a South Gate quote and not our price. Your own number comes from the written estimate once I've seen the site.

How do I decide between an all season room and a three season room?

Decide by how you'll use the room, because the price gap is real. A three season room uses non-insulated windows, which cost less than the dual-pane insulated windows of a four-season room, but it also goes without the insulation and heating and cooling. If you want a room that works like the rest of the house, that's the all season room.

What is the best way to add an all season room to an existing deck or patio?

Start by checking what you've got, because a site-built room needs a proper building foundation while a prefab kit can attach to an existing wooden deck or patio with a level surface. A level deck or patio keeps a kit on the table, and a site-built room adds foundation work to the plan.

How much can a contractor ask for up front on a sunroom in California?

California's contractor board says a contractor can't ask for a down payment over $1,000 or 10 percent of the total contract price, whichever is less. The other payments should be listed in the contract and match work completed or materials delivered, so you pay as the room takes shape.

Can I pull my own permit for a sunroom in South Gate?

Yes, as an owner-builder, if you live on the property and it has 2 units or less, and the city asks for ID showing you live there. If friends or anyone outside your household help with the work, you're the one who provides workers' compensation insurance for them.

What license does a contractor need to build a sunroom in California?

The state's B General Building license covers contractors who mainly build shelters for people or property using at least two unrelated building trades. An all season room usually means framing, glass, wiring and heating and cooling on one job, so it's fair to ask which license a contractor holds before you sign.
