Services in Rialto, CA
Patio-to-sunroom conversion
Plenty of Rialto backyards already have a covered patio off the back slider, so closing one in is the call we get most. We add the walls, windows and roof connection that make it a room you can use, and we tell you plainly whether the cover you have is worth keeping.
Sunroom additions
Many single-story houses here have space behind them for a new room off the back, and those jobs come down to how the new roof meets your existing eave. We plan that tie-in and the footings before we pick panels, because those are the parts that decide whether the room stays dry.
Sunroom remodeling
Older sunrooms and enclosed patios on Rialto houses tend to give out at the seams, and the first sign is usually a stain on the wall or a damp floor. Our sunroom remodeling work starts by finding where the water actually gets in, then replacing the flashing, panels or roof behind it instead of adding more caulk.
Deck-to-sunroom conversion
On the Rialto houses that have a wood deck instead of a slab, the deck was usually framed for people and chairs, not walls and a roof. We look at the posts, beams and footings underneath and reinforce or rebuild them before any room goes on top.
Screen room installation
Some homeowners here just want to sit out back in the evening without the bugs, and they don't need glass or heating to do it. A screen room on your existing patio is the lighter route, and we can frame it with windows in mind if you think you'll want them later.
Patio cover installation
Older aluminum covers are common over Rialto patios, and by now many have sagging beams or rusted fasteners. We replace them with a new cover set on proper footings, and if you might close it in someday, we size the posts and beam with walls in mind.
Rialto, CA properties and local conditions
Most of the houses we see in Rialto are single-story stucco homes with a sliding door onto a concrete patio, and a lot of them have a patio cover someone added years ago. Those slabs were usually poured for furniture, not for walls and a roof, so before we plan a room on one I check how thick it is, look for cracks and settling, and see how water runs off it and away from the house. If the slab won't carry the room, we say so and plan new footings rather than build on a guess, because the joint where the room meets the floor and the house wall is where leaks start.
The city's own building code findings note two earthquake fault systems inside city limits, the San Jacinto and the Rialto-Colton, though that's a finding for the whole city and doesn't map any one lot. That's why the connections at the footing and at your house wall get our closest attention, and we build them to the plans the city reviews.
What we deal with on a Rialto sunroom job
Rialto's Building Department issues the permits for building, altering or removing any structure in the city, and its list names patios and accessory buildings, so when a sunroom job needs a permit, the city's review usually sets the start date more than our schedule does. When yours needs one, we find out which office covers your address, prepare and file the paperwork, and meet the inspector on site, and we'll tell you what we know and what's still up to the city. Any contractor you hire here should hold a state license you can look up with the Contractors State License Board, and the city also requires a Rialto business license of every state-licensed contractor and subcontractor working in the city. We're fully licensed and insured. What moves your price is mostly the room's size, glass or screen, and what it sits on, and your own number comes in the written estimate after I visit.
We come up from Riverside, and Rialto sits right between jobs we do in Fontana and Colton, with Grand Terrace just south of Colton. One thing that trips people up is that grading the yard or any work in the public right of way goes through the city's Engineering Department, a separate permit from the building one, so I look for that on the first visit.

Call or send a request
Call (951) 394-2905 or use the form, and we'll get back to you to set a time to come out. You don't need plans or sizes ready, just an idea of what you want.
I measure and talk it through
I come out, measure, look over the patio, deck or wall the room will join, and ask how you'll use it, so it helps if you're home for this one. Then I send a written estimate, so you see the price before you commit to anything.
We file and wait on review
If the job needs a permit, the city says patio permits are often reviewed and issued within 10 business days, Monday to Thursday, while other permits get a tentative 20 business days of plan review and a tentative 10 more to become a permit. Corrections start that 20-day review over again, so we work to get the plans complete the first time.
We build and walk through it
Our installers build the room with me, and we bring in licensed trades when it needs electrical or heating and cooling work. At the end we walk through it with you, and every room is backed by our satisfaction guarantee.
Frequently asked questions
Do I need a permit to build a sunroom in Rialto?
Check with the city before anything gets built, because Rialto's Building Department issues permits for building or altering any structure in the city, and its list names patios and accessory buildings among the work it covers. Sunrooms aren't named on that list on their own, so we find out how the department treats your particular plans before we file.
How do I apply for a building permit in Rialto?
Applications go through the city's Online Permit Center, which also handles business licenses, fire prevention and engineering permits. Every permit needs a signed declaration attached, along with the ID of the person who signed it, and when we're filing for you, we'll tell you if the city needs your signature.
When does a contractor need a California license to build a sunroom?
Under the state board's rules, a contractor needs a license to build or alter a structure whenever the project needs a building permit, uses employee labor, or has contracts that total $1,000 or more in labor and materials. The board lists some exemptions, such as qualifying owner-builders, but a hired sunroom job will usually pass that $1,000 mark, so ask for the license and look it up before you sign.
How do I find out if my Rialto home is in a fire hazard severity zone?
You check it by your address, because fire hazard severity zone status varies from one property to the next, and the city has a page on fire hazard severity zones. The state fire marshal issued recommended maps for San Bernardino County in 2025, so go by the current map rather than something a neighbor heard years ago. Tell me what you find when I come out, and we'll keep it in mind as we plan.
Do solar panels or an EV charger on my Rialto sunroom need their own permit?
Yes, the city lists solar panels, EV charging stations and battery storage among the building components that need a permit of their own. The city says that list isn't complete, so if you're thinking about adding any of these with the room, mention it at the first visit and we'll plan the paperwork together.
What makes a sunroom cost more or less in Rialto?
The biggest swings here come from what's already behind your house, because an old slab or deck that needs new footings, or an aging patio cover that has to come down, adds work before the room even starts. Electrical or heating and cooling adds licensed trades and can mean more permits, while keeping a slab and cover that are still sound is the simplest way to hold the cost down.
About Rialto, CA
Rialto sits between Fontana and San Bernardino, and most of it is single-family neighborhoods, with warehouses and businesses closer to the freeways. The houses run from older ranch homes near the middle of the city to newer tract neighborhoods farther north, and on both, the calls we get are mostly about closing in a back patio or adding a room off the back of the house.
That mix shapes the job more than the street does. Older homes tend to have thinner slabs and add-on covers that need a hard look, while newer ones usually have a better base but tighter yards, so planning a room here starts with what's already behind your house.
