Rialto backyards and the slabs under them
Rialto sits between Fontana, where we're based, and San Bernardino, so for a sunroom contractor in Fontana, CA, it's a short drive for our crew. Most of the houses we see here are single-family homes with a fenced backyard, a slab patio off the back door and, often enough, a patio cover that's been there longer than the current owners.
That slab and that cover decide a lot of the job. If they're sound, we build on them, and if they're not, you'll hear it from me at the estimate rather than halfway through the build.
Working in Rialto: who signs off and what moves the price
The city's Building Department issues the permits for building or altering structures in Rialto, and its list names patios and accessory buildings, which is where most of our work lives. When your room needs a permit, we pull it in our name, do the drawings and handle the inspections, so the permit counter is our problem and not yours. Before you sign with anyone, check two things, a California contractor's license and a Rialto city business license, which the city requires of state-licensed contractors who bid on or do improvement work here. We're licensed and fully insured, and I'm glad to show you the paperwork.
The permit is also the biggest thing your schedule turns on, because the city's review runs on its own clock and I'd rather get the drawings right before they go in than answer questions after. The price moves with the size of the room, whether it's built for year-round use and whether the slab or deck under it can carry walls as it is, and your written quote gives you your own number. Every city runs its own review, so a Rialto timeline won't match one from Fontana or Colton, even for the same room.
What do Rialto backyards need before a sunroom goes up?
A lot of Rialto patios weren't poured with a room in mind, so the first question is whether the slab can carry walls, glass and a roof without settling or cracking. I look at its edges, how thick it is where I can see it and how it meets the house, and then we either build on it, add footings or tell you it's time for new concrete.
The city's own building code findings put two earthquake fault systems, the San Jacinto and the Rialto-Colton, inside city limits, though they don't map any single lot. That's why we pay close attention to how a room ties into your house and sits on its base, and we plan it before anyone picks up a tool.

Sunroom work we do in Rialto
Patio-to-sunroom conversion
Plenty of Rialto houses already have a slab patio off the back door, and that's the natural spot for a new room. We check the slab first, then build the walls, roof and glass on it or tell you what it needs before it can carry them.
Four season sunrooms
If you want a room you'll use every month of the year, four season sunrooms are insulated and glazed to be heated and cooled like the rest of the house. We bring in licensed trades for the electrical and the heating and cooling so the room works the way you pictured it.
Patio enclosures
When an existing patio cover is in good shape, enclosing it is often the shortest path to more usable space. We look hard at the posts and beams first, because walls and windows ask more of them than a roof alone ever did.
Patio cover installation
Some Rialto backyards just need a roof over the slab and a place to sit. We size and attach the cover for your house and set it up so you can enclose it later if you change your mind.
Screen room installation
A screen room keeps the bugs out and the air moving, and it asks less of your slab and your budget than a glassed room. It's a good fit if you mostly use the patio in the evenings.
Sunroom remodeling
Older sunrooms and enclosures around Rialto often show up with tired glass, worn seals or a roof that's seen better days. We fix what's worth fixing and tell you plainly when replacing makes more sense.
What happens after you call us about a Rialto sunroom
Call or send the form
Call (909) 346-1870 or use the request form, and we'll set a time that suits you. A photo of the patio helps if you have one handy.
I walk the site with you
I come out myself to look at the slab or deck, the back of the house and how you want to use the room, so plan to be home for this part. You get a written quote that says what's in the price and what isn't, so nothing turns up later as a surprise.
We handle drawings and permit
We do the drawings and pull the permit in our name, and the schedule we give you already counts the city's review. By the city's tentative estimate, patio permits are often reviewed and issued within 10 business days, and most other permits take longer.
We build, then walk through
Our crew builds the room, and we bring in licensed trades for electrical or heating and cooling when it needs them. When it's done, I walk the finished room with you and we go over anything you want looked at.
Get a written sunroom quote for your Rialto home

Questions about sunrooms in Rialto
How long does it take to get a sunroom permit in Rialto?
For permits beyond a simple patio, the city's tentative estimate is 20 business days of plan review, then about 10 more business days to turn it into a permit. Corrections or revisions start that 20-day review over again, which is why we'd rather get the drawings right the first time than trade them back and forth with the city.
How do I check if a contractor is licensed to build a sunroom in Rialto?
Look the contractor up with the California Contractors State License Board, which licenses contractors in this state. The board requires a license to build or alter a structure when the project needs a building permit or uses employee labor, or when the contracts on it add up to $1,000 or more in labor and materials. Ask for the license number and check it yourself before you sign.
How do I find out if my Rialto home is in a fire hazard severity zone?
Look up your address, because fire hazard severity zone status varies from one property to the next and is checked by address. The state fire marshal issued recommended maps for San Bernardino County, and the city's fire hazard severity zone page is the place to start. Tell me what you find at the estimate so we can plan the room with it in mind.
Does a Rialto sunroom need a separate permit for solar panels or an EV charger?
Yes, the city lists solar panels, EV charging stations, battery storage and on-site generators among the items that need their own permit, and it says that list isn't complete. If your room comes with any of those, we sort out which permits apply before we set the schedule.
How much does a sunroom cost in Rialto?
Your price comes from the room you choose and the house it attaches to, so the only honest number is the one in your written quote. The biggest swings come from stepping up from a screen or three season room to a four season room you'll heat and cool, from a slab that needs work before it can carry walls, and from extras like electrical or solar that bring their own permits. If the budget's tight, I'd rather build you a good three season room now than a cut-rate four season one.
What building code does Rialto use for a sunroom addition?
The city reviews building work under the California Building Code and the Rialto Municipal Code. Its stated plan was to adopt the 2025 California Building Standards for applications and plans submitted after December 31, 2025, and we draw your room to whatever code the city reviews it under.
