Request an estimateCorona backyards that already have a patio
A lot of the Corona backyards I walk into already have something in them, usually a concrete patio with an aluminum or wood cover over it, and the homeowner wants to turn it into a room they'll use instead of just walk past. You see older homes closer to the middle of the city and newer tracts farther out, and the question is the same in both: can you close in what I've already got? It's the same call we get next door in Norco.
Some Corona lots also fall under the city's construction requirements for fire hazard severity zones, which can change how a room on those lots has to be built, so we look into that for your address early. Mostly, though, the job here turns on that existing slab and cover, because they were built to shade open air, not to hold walls, windows and a roof, and I check them before we plan anything around them.
Working in Corona: permits, licenses and what moves the price
In Corona, building permits come from the city's Planning & Development department, and its permit line is 951-736-2250 if you want to ask about your address. Whether your room needs a permit is the city's call, and when it does, the permit and its inspections set part of the schedule, because each stage of the build waits until the inspector signs off. Before you hire anyone, ask for two things: a California contractor license and a Corona business license, which the city requires even of contractors based elsewhere, like us. We're licensed and fully insured, and when a job needs a permit, I put the paperwork together, submit it to the city and meet the inspector for each visit.
We come over from Eastvale the same way we do for jobs in Ontario and Riverside, so a Corona room gets the same planning and the same installers, with me checking in on site. The price moves most with the size of the room, how much glass it has, and whether we can build on your existing slab and cover or need new footings first. The schedule turns on the permit, the materials you pick and how quickly we settle the design, and the estimate visit is where you get your own number.
Services in Corona, CA
Patio-to-sunroom conversion
Patio-to-sunroom conversion is a call we hear a lot in Corona, from homeowners with a slab and cover they barely use. We check whether the slab and posts can carry walls and a roof, then frame the room on what's sound and replace what isn't.
Three season sunrooms
A three season sunroom suits Corona families who want a bright room for most of the year without paying for a fully insulated addition. We build them with framed walls and large windows, so you can open the room up or close it off as you like.
Patio enclosures
Patio enclosures fit Corona yards where the cover is solid and you mainly want walls to keep leaves, dust and bugs out. We fit the enclosure panels to your existing cover and seal the edges where they meet the house.
Patio cover installation
Plenty of Corona backyards have a bare slab and no shade, and a patio cover is the simplest place to start. We set the posts and tie the cover into your house, and if you might close it in later, we plan for that from the start.
Four season sunrooms
When you want the room to feel like part of the house all year, a four season sunroom with insulated walls and roof is a better fit than enclosing a patio. We plan the foundation, framing and roof tie-in the way you'd plan any addition, which is why I spend extra time on the drawing.
Screen room installation
Screen room installation works for Corona homeowners who mostly want to sit outside in the evening without bugs and don't need glass. We build a frame with screen panels under a solid roof, which costs less and goes up faster than a glass room.

Frequently asked questions
How much does a sunroom cost in Corona, CA?
The price of a Corona sunroom comes down mostly to its size, whether it's a screen room, a three season room or a four season room, and whether your existing slab and cover can carry it. Glass, roofing and any lights or outlets add to it, and new footings add more if the old slab isn't up to the job. I'll give you your own number after a free visit to your backyard.
Does a sunroom contractor based outside Corona need a Corona business license?
Yes, the City of Corona requires a business license for every business operating in the city, including contractors whose main address is somewhere else. The license renews every year on its anniversary, so it's fair to ask a contractor whether theirs is current.
When does a contractor need a California license to build a sunroom?
A contractor needs a state license from the Contractors State License Board whenever the job needs a building permit, uses any hired workers, or comes to $1,000 or more in labor and materials. The limit for small unlicensed jobs went up from $500 to $1,000 at the start of 2025, but only for work with no permit and no hired help, and a sunroom of any size runs well past that.
Which building code does Corona use for sunroom additions?
The Corona City Council adopted the 2025 edition of the California Building Standards Code in November 2025, bringing it into the city's own building rules. We draw your room's plans to the code the city is checking against when we apply, so the review goes the way it should.
How do I schedule a building inspection for a sunroom in Corona?
Corona inspections are booked online for Monday through Thursday, and a Friday inspection is only for an unusual situation or hardship, by calling (951) 736-2250 no later than Wednesday at 5:00 p.m. When we're building your room, I meet the inspector for each visit, and we plan the work around those weekdays.
What is the best way to turn a Corona patio into a sunroom?
The best way is to start by checking what's already there, because a lot of patio slabs and covers were built to shade open air, not to hold walls, windows and a roof. If they're sound and sized right, we can often build on them, and if not, we add footings or new posts before the walls go up. I'll look at yours on the estimate visit and tell you plainly which way it goes.
