Can I turn my patio into a sunroom?
A patio-to-sunroom conversion in Twentynine Palms puts a sunroom on the patio slab you already have. It closes in that space beside your house with walls, windows and a roof, so it becomes a room you can use for more of the year.
Most patios were poured as a place for a grill and a few chairs, not as the floor of a room, so the job starts with what the room will sit on. The price moves with the size of the room, whether you want heating or cooling in it, and how much work the slab and the edge along your house need. The schedule turns mostly on the city's permit review and on any footing work that has to happen before the walls go up. Your own figure comes from the estimate, which I write after I've seen your patio in person.
How we handle a patio-to-sunroom conversion
A patio slab wasn't poured with a room in mind, so I start by looking closely at the slab and at the line where it meets your house. I check whether it's level, cracked or settled and whether the walls will need new footings under them, because a room is only as sound as what it sits on. Then I lay out the options for that edge along the house and talk through what kind of room your patio can become, from a simple room with no heating or cooling to one that works like the rest of your house. Once the plan is settled on paper, our crew prepares the base, frames the walls and roof, sets the windows and doors, ties the room into the house and cleans up.
If your outdoor space is a wood deck instead of a slab, a deck-to-sunroom conversion starts with a different set of questions about the framing underneath. And if you want a room you can heat and cool for use in any month, take a look at our all season rooms.
Patio-to-sunroom conversion in Twentynine Palms, from permit to footings
A sunroom on your patio is a new structure, and in Twentynine Palms the city's Building and Safety Division issues the permits and does the inspections on structures built in the city. Where your job calls for a permit, we prepare the plans, file them with the city and handle the inspections. Any contractor who requests a permit or submits plans here also has to hold a City of Twentynine Palms business license. If the walls need new footings, Underground Service Alert asks anyone digging to call 811 or use digalert.org at least two days before work starts, so that request goes in before we break ground.
We're based in Twentynine Palms, and a lot of the patios we look at here were added after the house went up, often under an older cover on posts. That's why the slab doesn't always meet the house the way a floor would, and I sort out that joint before anything gets drawn. We see the same kinds of patios on jobs in Joshua Tree, Yucca Valley and the other cities around them.

What happens after you call about a patio sunroom?
Call or send the form
Call (760) 362-8204 or send the form with a few lines about your patio, and we'll get back to you to set up a visit. Photos of the slab and the back of the house help me come prepared.
I measure and write it up
I come out, measure the patio, look at the slab and how the room will join your house, and talk through what kind of room you want. Then I write an estimate that spells out what the price covers and what it doesn't, so you can see where the money goes.
We handle plans and permits
Once you say go, we draw the plans and file them where your job needs a permit. Building waits until the city approves them, which is why we settle the room type and the slab edge with you first.
Our crew builds the room
Our crew builds the room, and I check in on it as it goes up. When it's done, I walk through the finished room with you.
Why Twentynine Palms homeowners call us for patio sunrooms
The owner writes your estimate
I'm the one who comes out, measures your patio and writes the estimate, and I check in while our crew builds. You're talking to the person who drew up the plan, not passing questions down a line.
Building sunrooms since 2020
We've been building sunrooms since 2020, and most of our calls come from Twentynine Palms and the cities around it. I like the jobs with a puzzle in them, and a slab that meets the house in a strange spot is exactly that kind.
Licensed and insured on your job
We're fully licensed and insured, and in California contractors are licensed by the Contractors State License Board. That matters because a sunroom joined to your house is a building project, and you want someone accountable for it.
Big decisions settled on paper
Before anything gets built, I sit down with you and settle the room type, the slab edge and the windows on paper. Those are the choices that cost the most to change once the walls are up.

Questions about patio-to-sunroom conversion in Twentynine Palms
How much does it cost to turn a patio into a sunroom in Twentynine Palms?
A three-season sunroom built on an existing structural base in the San Bernardino area usually runs about $100 to $140 per square foot with installation labor included, and that's the market's figure, not our price. Bigger rooms, rooms that need a foundation and rooms with heating and air conditioning cost more, and one San Bernardino estimate leaves out insulation, extending heating or cooling, plumbing and permits, which all add to it. Your own number comes from the estimate I write after seeing your patio.
Can my patio slab hold a sunroom?
Usually, though the walls often need footings under them. A sunroom on a concrete patio needs footings down to the frost line wherever footings have to reach that depth, and where there's no frost depth they only need to be what the structure requires, so the footing plan depends on where your house sits. The footings are part of the plans, so you'll see them before any work starts.
What is the best way to handle a patio slab that sticks out past the house?
One construction guide lists three ways: a concrete block curb, a wood curb bolted to the slab, or cutting the slab back. A curb raises the wall above the slab edge, while cutting the slab removes the ledge entirely. Which one suits your patio depends on how far the slab runs out and how you want the floor to meet the house, and we settle that with you before building.
How do I choose what kind of sunroom to put on my patio?
Start with whether you'll want to heat or cool the room, because that choice shapes most of the rest. The National Sunroom Association sorts sunrooms by whether they have heating or cooling and whether they stay sealed off from the house, running from a room with no system to one that's essentially a regular room addition. A room with its own heating or cooling can keep your house's existing doors and windows in place, which keeps it thermally separate from the rest of the house.
What should a sunroom contract include in California?
California requires a written contract for any home improvement job over $500 in combined labor and materials. The license board says it should list the work, the price, when payments are due, who gets the building permits and the finish date, and it must show the contractor's address and license number.
How much can a contractor ask for as a down payment in California?
No more than $1,000 or 10 percent of the contract price, whichever is less. California makes no exception for special-order materials, so a big window order doesn't change that limit.
