What goes into a sunroom addition, and what sets the price?
A sunroom addition in Temescal Valley is a new room built onto your house and closed in with windows or screens, so the patio or yard you hardly use becomes a room you'll actually sit in.
Most of our calls start with a bare patio, an old deck or a tired cover nobody sits under, and if you've already got a patio out back, a patio-to-sunroom conversion may be where we begin. The price moves with the size of the room, whether it's heated and cooled, what it sits on and how much glass and insulation it gets. The schedule mostly turns on the permit and on getting each trade in at the right time. I'd rather you know what you're buying before you sign, so your written estimate spells out the price for your room in plain words.
How we build a sunroom addition
I start by asking how you'll use the room, then I measure, look at what it'll sit on and check how it meets the house wall. Insulated windows and insulation in the walls, floor and roof are much easier to put in while the room is going up, and adding them later often costs more, so we settle those with you before there's a price. An addition touches a lot of trades, from footings and framing to roofing, wiring and flashing, the metal strips that keep water out where the new roof ties into the house. I map out every one of them before we start and line them up in order, so nobody's standing around waiting while our crew builds from the footings up and cleans up before we walk the room together.
The first choice is the kind of room, because it decides the windows, the insulation and whether the room gets heating and cooling at all. If you want a room you can use in any weather, look at our four season sunrooms, and if you'd rather keep it simpler, our three season sunrooms are worth a look.
Permits for a sunroom addition in Temescal Valley
Temescal Valley is one of the county's unincorporated communities, so your permit comes from the Riverside County Department of Building and Safety, not a city hall. The county's list of projects that need a permit names room additions and patios but doesn't use the word sunroom, so I don't guess and I check with the county for your address. When the work needs a permit, we put together the plans and paperwork, file with the county and are there for the inspections.
Riverside County now has the state's fire hazard maps, which rate areas Very High, High or Moderate, so I look up where your lot falls before we draw the room. We're based in Temescal Valley and work across this part of Riverside County, and we run into the same bare patios and worn-out covers on jobs in Corona and Lake Elsinore.

Why Temescal Valley homeowners call Temescal Valley Sunrooms & Patios for additions
I measure and price it myself
The person who looks at your base and your house wall is the same one who writes your price, so nothing gets lost between a salesman and a crew. I'd rather talk you into a smaller room than sell you one that doesn't fit how you live.
Our own crew, me on site
I started this business in 2023, coming back to a trade I learned young building patio covers and enclosures. Our own crew does the building with me running the job on site, and we bring in licensed trades for the electrical or heating and cooling.
Licensed and fully insured, every job
We're licensed and fully insured, which is worth asking any builder about before they set foot on your property. Satisfaction guaranteed on every job.
Planned to California's energy rules
California's Energy Code sets energy and water efficiency requirements for additions to existing houses, not just new ones. That's one more reason we settle the windows and insulation with you before we price the room.
What matters most on an addition is getting the room right on paper before anyone digs a footing. Ask for your on-site estimate and we'll start there.

Questions about sunroom additions in Temescal Valley
What's the difference between a four season and a three season sunroom?
A four season room is heated and cooled and has all-weather windows, while a three season room isn't heated or cooled and uses uninsulated windows or screens. A screened porch has screens only, so the type you pick decides whether the room has windows and temperature control at all. I'll ask how you plan to use it before I steer you either way.
How much does a sunroom addition cost in the Riverside area?
Building a sunroom usually costs about $95 to $200 per square foot, going by figures for the city of Riverside. Bigger rooms that need a foundation and have heating and air conditioning land toward the high end of that range. Your written estimate gives the price for your room.
Does a contractor need a license to build a sunroom in California?
Yes, in most cases. California requires a Contractors State License Board license to build or alter a structure when the project needs a building permit, uses additional workers or costs $1,000 or more in labor and materials. A sunroom addition usually clears that bar, so ask any builder for their license before you sign.
How do I look up my home's fire hazard zone in Temescal Valley?
You can check it on the State Fire Marshal's fire hazard zone map by typing in your address, and it shows where your property sits among the zones. I'm happy to pull it up with you during the visit.
Who coordinates the trades on a sunroom addition?
Usually the general building contractor does. The state licensing board says general building contractors usually oversee a project and coordinate the subcontractors, so it's fair to ask every bidder who'll be lining up the trades on your sunroom. On our jobs, that's me.
How do I take care of a sunroom roof?
Look over the roof and gutters once a year, and stay off the roof unless you need to be up there. That's what one sunroom maker's guide suggests, and it goes for any roof, the sunroom's included.
Two kinds of sunroom to compare
Four season sunrooms
For a room you want heated and cooled, so it works as everyday living space.
Three season sunrooms
For a lighter room without heating and cooling, when you mostly want a sheltered spot with a view.
