Rialto: two fault systems under the city
Rialto sits right next to Bloomington, where I started this business in 2017, so it's close to home for our crew. Most calls here are about the back of the house: a concrete patio under an old cover, a wood deck that's seen better days, or a sunroom added years ago that now leaks at the wall or sticks at the doors. We see the same mix of older single-story houses and newer tracts here that we see next door in Fontana, and most of them have a back slab or a slider that makes a good place to start a room.
The city's building code findings say two earthquake fault systems, the San Jacinto and the Rialto-Colton, run within Rialto's limits. That covers the whole city and maps no single lot, but it's why I won't treat a sunroom as a kit screwed to the siding. How the room ties to your house and what it sits on get worked out on plans the city reviews before anything goes up.

Sunroom work we do in Rialto
Patio-to-sunroom conversion
Plenty of houses here already have a concrete patio out back, and that slab is usually where a sunroom starts. We check its thickness and edges before we plan on it, because a slab poured for a barbecue isn't always ready to carry walls and a roof.
Three season sunrooms
A three season sunroom suits a lot of Rialto backyards where people want glass and screens around the patio without heating and cooling it like the rest of the house. It costs less than a fully insulated room, and I'll tell you plainly if it fits the way you plan to use the space.
Four season sunrooms
If you want a room you can use like any other room in the house, a four season sunroom is built with insulated walls, an insulated roof and better glass. It costs more than a three season room, so I'll walk you through both and you pick the one you'll really use.
Deck-to-sunroom conversion
A raised wood deck can become a room, but only if the framing under it can take the added weight of walls, glass and a roof. We look underneath first and tell you straight whether it needs new footings or whether starting fresh makes more sense.
Sunroom remodeling
Older add-on sunrooms around Rialto often have fogged panels, tired seals or a roof that drips where it meets the house. We'll tell you whether a remodel fixes it or whether the frame is too far gone to be worth the money.
Patio cover installation
Some people don't want walls at all, just shade over the slab they already use. We tie the cover properly to your house, and if you think you'll enclose it later, we size it for that from the start.
Working in Rialto: permits, licenses and price
Rialto handles its own permits, so the office we deal with here is the city's Building Department, which issues permits for building or altering any structure in the city. Its list names patios and accessory buildings and doesn't mention sunrooms either way, so before we set a start date I confirm with the city what your job needs, and we take care of the permit paperwork when it calls for one. You can check two things about any contractor you're weighing: a state license with the Contractors State License Board, and a Rialto business license, which the city requires of state-licensed contractors who bid on or do improvement work here. We're licensed and fully insured.
The price moves mostly with what we're building on and the kind of room you choose, and the schedule usually turns on the city's review more than on our crew, because nothing goes up until the permit is issued. I do the estimate at your house myself, and our own crew builds the room with me checking it as it goes, the same way we work next door in San Bernardino and down in Colton. The estimate is where you get the number for your house.

Sunroom ideas for Rialto homes
Rialto sunroom questions
How much does a sunroom cost in Rialto?
The cost of a sunroom in Rialto comes down mostly to the base it sits on, the type of room and what goes inside it. A sound slab keeps the price down, a deck or patio that needs new footings adds to it, and an insulated four season room costs more than a three season room with screens. Size, the roof style, electrical and any solar add to it as well, and I'll give you your own number after I've seen the house.
How long does a building permit take in Rialto?
The city says patio permits can often be reviewed and issued within 10 business days, Monday through Thursday, while other permits get a tentative 20 business days of plan review plus a tentative 10 more to become a permit. If the plans come back with corrections, that 20-day review starts over. That's why we try to get the drawings right the first time.
Do I need a separate permit for electrical or solar on a sunroom in Rialto?
Often, yes, because electrical work is on the city's list of work that needs a permit, and a city handout says items like solar panels, EV charging stations and battery storage need their own permit. The handout also says that list isn't complete. If you want lights, outlets or solar on the new roof, tell me at the estimate so we can plan those permits from the start through the city's Online Permit Center.
When does a contractor need a state license in California?
A contractor needs a license from the state licensing board to build or alter a structure whenever 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. Nearly any sunroom passes that line, so ask anyone you're considering for their license and check it with the board before you sign.
How do I find out if my Rialto home is in a fire hazard zone?
Look up your address on the city's fire hazard zone page, because fire hazard severity zone status is set property by property, not for the whole city. The state fire marshal released recommended zone maps for San Bernardino County in 2025. If your lot shows up in one, mention it at the estimate and we'll confirm with the city what it means for your room.
Which building code applies to a new sunroom in Rialto?
The city has said it would adopt the 2025 California Building Standards starting January 1, 2026, and that permit applications and plans submitted after December 31, 2025 fall under them. The Building Department also works under the California Building Code and the city's own municipal code. We draw your plans to whatever the city is reviewing under when we submit them.
