What does it take to turn my patio into a sunroom?
A patio-to-sunroom conversion in Temescal Valley closes in the patio you already have with windows or screens, so the slab behind your house becomes an enclosed room you can sit in, work in or hand over to the kids.
Most folks who call me have a bare slab or a tired cover out back and a hunch they could be getting a lot more out of it. The first thing we sort out together is whether you want a closed-in patio you use most of the year or a room that's heated and cooled for all of it, because insulated windows and insulation in the walls, floor and roof go in much easier while we're building than later, when adding them usually costs more. Size moves the price the most, and a bigger room that needs a foundation plus heating and air lands at the high end, while the schedule mostly turns on getting the county permit through plan check. Once I've seen your patio, I'll put your number in a written estimate in plain words.
How we handle a patio-to-sunroom conversion
Before anybody cuts into your patio slab, we find out what kind of slab it is, because some have steel cables running through them under tension, and you do not want to hit one. Once we know, we plan the footings and walls around it, set the frame and tie it into your house wall so the two shed water together, then put on the roof, fit the windows or screens you picked and clean up before we hand the room over.
Not every outdoor space starts on a slab. If yours is a raised wood platform, our deck-to-sunroom conversion work starts from what's holding that deck up. If you already know you want a room you'll use in July and January alike, we build it as one of our all season rooms, and we bring in licensed trades for the wiring and the heating and cooling.
Patio-to-sunroom conversion permits and conditions in Temescal Valley
Temescal Valley isn't its own city, so your permit doesn't come from a city hall. It's an unincorporated part of Riverside County, and the Riverside County Building & Safety Department issues the building permits for enclosed patios, patio covers and additions here, then handles the plan check and the inspections. When your job needs a permit, we put together the plans and paperwork, file them with the county and are there when the inspector comes, and if you'd like to ask the county something yourself, you can reach them at (951) 955-1800.
Most patios we see out here sit behind stucco homes and take a long, hot inland summer, so at the visit we spend real time on which way the room faces and how much glass catches the afternoon sun. We run into the same slabs and the same heat on jobs in Corona and Lake Elsinore, and we work across this part of Riverside County from our base in Temescal Valley.

What happens when you call about closing in your patio?
Call or send your request
Call (951) 336-8162 or send the form with a line about your patio, and we'll set up a time for me to come out. We pick up Mon–Fri from 6 AM to 9 PM and Sat–Sun from 7 AM to 9 PM.
I come out and measure
I measure the patio, check what the room will sit on and how it meets your house wall, and ask how you plan to use the space. That talk decides whether you need screens, all weather glass or a room with heating and cooling.
You get a written estimate
You get the price in writing and in plain words, so you know exactly what the room includes before you sign anything. Take your time with it and ask me about anything that isn't clear.
We permit, build and walk through
Once you say go, we handle the permit paperwork with the county, and our own crew builds the room with me running the job on site. When it's done, we walk through the finished room together.
Why Temescal Valley homeowners call Temescal Valley Sunrooms & Patios
The owner measures every job
I come out and do the measuring myself, then run the job on site while our own crew builds, with licensed trades brought in for electrical or heating and cooling. You deal with the same person from the first visit to the final walk-through.
Licensed and fully insured
We're licensed and fully insured, and that matters because California's contractor board requires a license for any work that needs a permit of any kind, even a job under $1,000. Closing in a patio is permitted work, so ask anyone you're considering to show you theirs.
Talked through before it's priced
I'd rather talk you into a smaller room than sell you one that doesn't fit how you live, so we go over how you'll use the space before any price goes on paper. Satisfaction guaranteed on every job.
Back to building rooms since 2023
I learned this trade on patio covers and enclosures, spent years in other work, and started this business in 2023 because I missed building something you can stand in. We're based in Temescal Valley, and the county permit route your job takes is the one we work with every day.
On a conversion, the room you'll really use beats the biggest one your slab can hold, so start by asking for an estimate and telling me how you picture the space.

Questions about patio-to-sunroom conversion in Temescal Valley
How much does a patio-to-sunroom conversion cost near Temescal Valley?
A sunroom in the Riverside area usually costs about $95 to $130 per square foot. That's what the local market runs for the room itself, not our price, and the size you pick and whether you want heating and cooling decide where yours falls. I'll give you a written number for your own patio after the visit.
Do I need a permit to add electrical or air conditioning to a sunroom in Temescal Valley?
Usually yes, because Riverside County lists electrical, plumbing, mechanical and structural work among the jobs that need a building permit, so wiring or cooling in your new room counts. We bring in licensed trades for that part and fold it into the county paperwork we file for the room.
What is the difference between a four season room and an enclosed patio?
A four season room is usually fully enclosed, heated and cooled, with all weather windows, while an enclosed patio usually has uninsulated windows or screens. Pick the one that matches the months you'll really be out there, since that choice sets the insulation and a good share of the price.
How much can a contractor ask for as a down payment in California?
In California, a down payment on a home improvement job can't be more than $1,000 or 10 percent of the contract price, whichever is less. That cap includes special order materials, and the exception is a contractor who holds blanket performance and payment bonds, so check any contract against it before you sign.
What license should a contractor have to enclose a patio in California?
Ask which license class they hold, because the state's awning class covers patio covers but doesn't include patio enclosures. A contractor licensed only for covers may not be the right fit for closing yours in.
How do I take care of a sunroom after it's built?
One maker's guide suggests checking the roof and gutters once a year and keeping the weep holes, the small drain openings in the frame, clear so water can get out. The same guide says to keep door and window tracks clean and use a pure silicone spray rather than an oil-based lubricant, which tends to pull in dirt.
