What is a three season sunroom, and what does it take to add one?
A three season sunroom is an enclosed room built onto your Temescal Valley home over a patio or deck, with walls whose openings hold glass or clear plastic. The national sunroom trade group describes this kind of room as a space kept apart from the house's heating and cooling, which is a big part of why it's a simpler build than a full room addition.
Most of the calls I get are from folks with a bare patio, an old deck or a tired cover who want a room they'll really use, and a three season room is often a good fit for that. The price mostly moves with the size of the room, what it sits on, whether you go with glass or clear plastic panels and whether you want lights or outlets run, while the schedule usually turns on county permit review and any work the base needs first. If shade is all you're really after, a patio cover may do the job, and I'll tell you so. Your own number comes from the estimate, where I measure the space, look at the base and the house wall and write the price up in plain words.
How we build a three season sunroom
Before anything else, I ask how you'll use the room and whether your back door and the windows on that wall stay put, because that decides whether you end up with a sunroom or something closer to a full addition. Keeping them usually keeps the room simpler, since the door and windows keep it closed off from the house, and a room that isn't closed off is essentially a regular addition. From there we sort out whatever the base needs, frame the walls, set the glass or clear plastic panels, tie the roof into your house wall, then finish it out and clean up so you're left with a room and not a job site.
Some yards are better served by a patio enclosure that closes in the space under a cover you already have. When your space or your plans don't fit a standard room, we build custom sunrooms laid out around how you'll actually use them.
Building a three season sunroom in Temescal Valley
Temescal Valley is unincorporated Riverside County land, so your building permit comes from the county's Building and Safety Division and not from a city hall. The county's permit list names patios and room additions but doesn't name sunrooms, so that list alone doesn't settle what your room needs, and that's a question for the county. When the work needs a permit, we put together the plans and paperwork, file with the county's Building and Safety office for your address and are there for the inspections.
We're based in Temescal Valley and work across this part of Riverside County, and a lot of the back yards we see have a concrete slab off the slider or a raised deck where the lot drops away. What the room sits on matters as much as the room itself, so I spend real time on the slab or the deck framing before we talk price. We see the same mix of slabs and older decks on jobs in Corona and Lake Elsinore.

I come out and measure
I measure, look at what the room will sit on and how it meets the house, and we talk about how you plan to use it. That's when we sort out the back door and the windows on that wall.
You get a written estimate
You get the price written out in plain words, with the base work, the room itself and the permit paperwork laid out, so you know exactly what you're buying. Nothing gets ordered or started until you say go.
We permit, build and walk it
We handle the permit paperwork, our crew builds the room, and when it's done we walk the finished room with you. That walk is your chance to point at anything you want a second look at.
Why Temescal Valley homeowners call us for three season sunrooms
I measure every job myself
I'm the one who comes out, measures and looks at what the room will sit on and how it meets your house. The person pricing your sunroom has had a tape on it, so the estimate matches the job.
Our own crew, me on site
Our own crew does the building with me running the job on site, and we bring in licensed trades for any electrical work. You aren't handed off to strangers once you've said go.
We're licensed and fully insured
We're licensed and fully insured, and you're welcome to ask about both at the visit. Ask anyone else you talk to as well, because California's licensing board says its awning license covers awnings and patio covers but not patio enclosures.
Talked through before it's priced
Since I started this business in 2023, I've heard from plenty of folks who were sold a room that didn't fit how they live. So we talk the room through before I put a price on it, and I'd rather talk you into a smaller job than sell you the wrong one.
Bring me your patio, your deck or just a rough idea, and send us a request or call (951) 336-8162 to set up a visit.

Questions about three season sunrooms in Temescal Valley
What does a three season sunroom cost near Temescal Valley?
A sunroom in nearby Riverside usually costs about $95 to $130 per square foot of room. That's the going rate in that market, not our price, and a base that needs work or a lot of glass tends to move a job around inside it. Your written estimate gives you the real number for your house.
Can a three season sunroom go on my existing deck?
Often it can, but an existing deck will typically need added beams, posts or footings to carry a sunroom's weight and loads. The national sunroom trade group says owners planning a deck sunroom start by having a local structural engineer check whether the deck is suitable. When I'm out there I look under it too, so we both know what we're starting with.
Can a sunroom be built on my concrete patio in Temescal Valley?
Usually, with the right footings under it. The trade group says a sunroom on a concrete patio needs continuous footings where footings have to reach the frost line, and where an area has no frost depth, footings may only be required as the structure needs them. That's why the ground under your slab shapes the base work, and why I check the slab and its edges before pricing anything.
Who issues building permits for a sunroom in Temescal Valley?
Riverside County does, through Building and Safety, since Temescal Valley isn't its own city. If you want to ask about your address, the county has a permit process advisor for this part of the county at 951-955-3219, and questions and status checks can go to landuseinfo@rivco.org. When we take the job, we handle the filing.
How do I check my fire hazard zone in Temescal Valley?
Enter your address in the state fire marshal's Fire Hazard Severity Zones viewer, and it shows where your property sits on the zone map. It's worth a look before the visit so we can talk it over with your address in front of us.
How long does it take to get a three season sunroom built?
Most of the wait usually comes before we build, while the plans go through county review and any deck or slab work gets settled. Once the permit's in hand and the base is ready, the building itself goes in a steady order, and we'll talk through the schedule with your estimate.
