How do I get a sunroom that fits my house and my lot?
A custom sunroom is a room Temescal Valley Sunrooms & Patios designs and builds onto your house from scratch. It's sized and laid out for how you'll use it and where it sits on your lot, and it can be anything from a screened seasonal room to a fully enclosed room that's heated and cooled. That's how we build custom sunrooms in Temescal Valley, CA.
Most folks who call us have a bare patio, an old deck or a tired cover and want a room they'll really sit in, which is why a lot of our custom jobs start as a patio-to-sunroom conversion. The price moves with the size of the room, whether it needs a foundation, the windows you pick and whether you want heating, air conditioning or fans. The schedule mostly turns on how fast we settle the design and how long the permit takes. I want you to know all of that before you sign, so after I've seen the space you get a written estimate with the price spelled out in plain words.
How we plan and build a custom sunroom
Custom means we start from how you'll use the room and where it sits on your lot, not from a catalog page. I ask a lot of questions first, like whether it's a morning coffee spot, a playroom or a place to watch the game, because the answer decides the size, the doors and whether the room gets heating and cooling. Before anything gets drawn up, we check with planning on how close to the property line we can build, since a design that doesn't fit the lot is just a nice drawing. Then our crew digs out and sets the base, frames the walls and roof, ties the room into your house wall, puts in the windows and doors, and cleans up when we're done.
If you already have a plan in hand and just need it built, that's our sunroom construction work, and if you've got an older room that leaks or bakes, sunroom remodeling can often save what's there. Wiring, heating and cooling go to licensed trades we bring in, and I run them on site like the rest of the job.
Building a custom sunroom in Temescal Valley means working with the county
The county's own permit guide doesn't settle whether your sunroom needs a permit. Riverside County Building & Safety handles building permits for the projects on its permit flyer, and that list names enclosed patios and additions but not sunrooms, so county Building & Safety is the place to ask about your exact room. When a permit is needed, we put together the plans and paperwork, file them with the county or city building office for your address and are there for the inspections. The county lists Temescal Valley among the communities its Permit Process Advisor serves, and it recommends applying online at rivcoplus.org. The State Fire Marshal's fire hazard zone map also shows which zone your address sits in.
Then there's the heat. July and August here average daily highs around 94 to 95°F, and the record is 114°F, so a glass room facing the afternoon sun can turn into an oven, and I'll talk through window choice, shade and cooling before we draw anything. We see the same summers and the same backyard patios on jobs in Corona and Lake Elsinore.

I come out and measure

Why Temescal Valley homeowners call us for a custom sunroom

I'm the one who comes out, does the measuring and writes your estimate, and I'm on site running the job while our own crew builds it. You talk to the same person from the first visit to the final walkthrough.
Building rooms here since 2023
I learned this trade on 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 the wrong room, so I'd rather talk you into a smaller job than sell you one that doesn't fit.

Questions about custom sunrooms in Temescal Valley
What is the difference between a three season and a four season sunroom?
A four season room is heated and cooled and has all-weather windows, while a three season room skips both and uses uninsulated windows or screens. That choice decides whether you end up with a temperature-controlled room or a simpler seasonal space. I'll ask how you'd use it in August before you pick.
How much does a custom sunroom cost in the Riverside area?
A sunroom in the city of Riverside usually costs about $17,000 to $120,000 per project, and that's the going range in the area, not our price. Larger rooms that need a foundation sit at the high end. Your own number comes from the written estimate after I've seen the space.
How much can a contractor ask for up front in California?
In California a down payment can't be more than $1,000 or 10 percent of the contract price, whichever is less, according to the state's Contractors State License Board. Any home improvement job over $500 needs a written contract, any changes to it have to be in writing too, and the contract must say who gets the permits and give a completion date.
What is the best way to insulate a sunroom?
The best way is to build it in from the start, with highly insulated windows and insulated walls, floor and roof. They make the room more energy efficient and are much easier to put in while the room goes up, since adding them later can often cost more. That's why I'd settle insulation with you in the first design.
Should my sunroom be open to the rest of the house?
Open it to the house if you want it to work like the rest of your living space. A national sunroom industry specification calls a heated or cooled room that's open to the house habitable, and a room with its own system that's closed off from the house non-habitable. It changes how the room ties into your house, so we decide it before anything gets drawn.
How do I take care of a sunroom?
Check the roof and gutters once a year, and stay off the roof unless you have to get up there, according to one maker's owner guide. The same guide says to keep door and window tracks clean, spray them with pure silicone so they slide easily, and keep the weep holes, the small drain slots at the bottom of the frames, clear.
Other sunroom work we do
Sunroom construction
When the layout is already settled and you need a crew to frame, roof and close in the room.
Sunroom remodeling
For an older sunroom that runs hot, leaks or feels dated, when you'd rather fix it than start over.
