What is an all season room, and is it right for your house?
An all season room in Temescal Valley is a fully enclosed sunroom with insulated walls, floor and roof, all-weather windows, and heating and cooling. That makes it a real room of the house that works year-round, not a porch you only use a few months.
Most folks who call us have a bare patio or a tired cover, and they want a room they'll sit in on an August afternoon and a January morning, not just in spring. If you'd rather have a simpler enclosed space without heating and cooling, a three season room can be the better buy, and I'd rather tell you that than sell you the wrong room. The price mostly moves with the size, whether it needs a new foundation, the heating and cooling, and how much glass goes overhead, while the schedule turns on the size of the room and the county permit. Your written estimate spells out those choices in plain words with a price beside them.
How we build an all season room
It starts with me at your house, measuring, looking at what the room will sit on and how it ties into the house wall, and asking how you plan to use it, because a reading nook and a dining room for twelve need different things. Then we settle the insulation in the walls, the floor and the roof, along with highly insulated windows, on day one, since those go in far easier while we build and adding them later often costs more. We also talk through the roof before anything is ordered, because national building guidance notes that on a midsummer day a square foot of roof can take in far more sun than a square foot of north- or south-facing wall, so a glass ceiling runs a lot warmer than a solid one. Once the design is set, we frame the room, insulate it, close it in and finish it.
Not every patio needs a fully heated and cooled room. If you want the space closed in with less going into it, our enclosed patio rooms are the simpler step, and if you want to look up at the sky from your chair, solarium installation is where we plan the glass roof from the first sketch.
Building an all season room in Temescal Valley
Temescal Valley isn't its own city, so permit questions for an all season room go to Riverside County, not a city hall. The county's Building and Safety Department issues building permits, and its list of projects that need one names patios and room additions but doesn't name all season rooms, so we ask the county how it treats your room instead of guessing. When the work needs a permit, we draw up the plans and paperwork, file them for your address and are there for the inspections. The state's Energy Code also sets efficiency rules for additions, and a builder can either follow methods already known to be efficient or design more freely as long as the room reaches the same overall efficiency, which is one more reason we pin down the insulation and windows early.
Before we plan a room, it's worth putting your address into the state's fire hazard zone map to see where your property falls. We're based in Temescal Valley and work across this part of Riverside County, from Corona and Norco down through Lake Elsinore, Menifee and Murrieta, and most of what we see is stucco homes with a slab patio or an aging cover facing a long, hot afternoon, the same as on our jobs in Corona and Lake Elsinore.

Why Temescal Valley homeowners call Temescal Valley Sunrooms & Patios for an all season room
I do the measuring myself
The person who looks at your base and your house wall is the same person who runs the job on site, not a salesperson handing off notes. Nothing gets lost between the estimate and the build.
Back in the trade since 2023
I learned this work building patio covers and enclosures when I was young, spent years in other work, and started this business in 2023 because I missed building something you can stand in. I heard from a lot of folks who'd been sold a room that didn't fit how they live, so I'd rather talk you into a smaller job than the wrong one.
Licensed and fully insured
In California, anyone contracting for work worth $1000 or more in combined labor and materials needs a current, valid license from the Contractors State License Board. We're licensed and fully insured, and you can check any builder you're considering with the board.
Our crew builds, licensed trades wire
Our own crew does the building with me running the job, and we bring in licensed trades for the electrical and the heating and cooling. You deal with one person for the whole room.
On a room like this, the insulation and the roof decide how much you'll use it, so it's worth getting them right before anything is built. Request your estimate or call (951) 336-8162.

Questions about all season rooms in Temescal Valley
What's the difference between an all season room and a three season room?
An all season room is heated and cooled and has all-weather windows, while a three season room usually has no heating or cooling and has uninsulated windows or screens. The choice comes down to whether you want a room for any weather or a simpler enclosed space for the milder months. We'll talk through which one fits how you'll use it.
How much does an all season room cost in Temescal Valley?
A sunroom in the Riverside area usually costs about $120 to $200 per square foot, and that range covers sunrooms of all types, not just heated and cooled ones. Larger rooms that need a foundation and have heating and air conditioning tend to land at the higher end. Your written estimate gives you the figure for your own room.
Where do I apply for a sunroom permit in Temescal Valley?
Permits go through Riverside County, with applications made through an online account at RivcoPLUS.org along with a complete job description, plans and other required documents. When your room needs a permit, we put that package together and file it for you.
What license does a contractor need to build a sunroom in California?
The builder needs a contractor's license from the state licensing board, and the board's own example says a remodel combining plumbing, electrical and carpentry under one contract calls for a General Building contractor. An all season room usually adds wiring and heating to the house, so it's fair to ask any builder which license covers that work.
Should an all season room open to the house or be closed off?
Either can work, but decide early, because one sunroom standard's summary treats a heated or cooled room open to the house as habitable space, while one sealed off with its own temperature control counts as nonhabitable. We settle which way you want it before the design is drawn, since it changes how the room is classed.
What is the best way to keep a sunroom cool in summer?
The best way is to block the sun before it reaches the glass, usually with shading on the outside, according to national window guidance. That's harder to rely on for east- and west-facing walls, where the sun comes in low, so we give the windows on those walls extra thought when we plan the room.
Other ways to close in your patio
Enclosed patio rooms
A closed-in patio for folks who want shelter from wind and dust but don't need heating and cooling in the room.
Solarium installation
Glass overhead and on the sides, with the extra heat that brings worked out before we start building.
Tell us the room you have in mind
When you call (951) 336-8162 or send the form, give us the rough size, whether it opens to the house and whether you want it heated and cooled, so the visit starts from your plan.
