Sunroom contractor in Rialto, CA - covered patios and decks turned into real rooms
Loma Linda Sunrooms & Patios is a sunroom contractor based in Loma Linda and building in Rialto. We enclose covered patios, slabs and decks, and build sunrooms, screen rooms and patio covers you'll actually use.

Rialto backyards with patios, slabs and decks
Rialto has a lot of single-family neighborhoods, and the calls we get here sound a lot like the ones from Fontana and Colton. Someone has a covered patio, a bare concrete slab or a wood deck off the back of the house, and they want a room there instead of a spot they walk past on the way to the yard.
That shapes the job from the first visit, because the new room has to fit the house, the roofline and the base that's already there.
Working in Rialto: permits, licenses and what sets the price
In Rialto, permits come from the city's Building Department. It issues them for building, altering or removing any structure in the city, and its list names patios, accessory buildings and electrical work. A sunroom usually involves more than one of those, so plan on a permit and on the city's review, not our crew's calendar, deciding when building can start. Before you hire anyone, check two things: a contractor license from the California Contractors State License Board, and a Rialto business license, which the city requires of every state-licensed contractor who bids on or does work here.
We're fully licensed and insured, and when a job needs a permit we put together the plans and paperwork, file with the city and meet the inspector for each inspection. The price turns mostly on what's already behind your house and how far you take it, from screens on a sound slab to a fully insulated room on new footings. The schedule turns on the city's review and how many stages need inspecting, and your written estimate gives you your own figure. Rialto is a short drive from our base in Loma Linda, and the work here looks a lot like what we build in Grand Terrace.
Services in Rialto, CA
Patio-to-sunroom conversion
A lot of Rialto houses already have a covered patio or slab out back, and that's usually the easiest place to add a room. Our patio-to-sunroom conversion work starts with checking that slab, then we build walls, windows and a roof it can actually carry.
Deck-to-sunroom conversion
A deck built for chairs and a grill usually needs new footings or heavier framing before it can hold walls and a roof. We check the posts and beams first and tell you plainly whether it can be built on or should be rebuilt.
Patio enclosures
When the patio cover is solid and the slab is sound, closing in the sides is often the quickest way to a usable room. We fit the walls and windows to the cover you have instead of tearing out what still works.
Screen room installation
Some homeowners here want the open-air feel without the bugs, and a screen room gets them that for less than full glass and insulation. We set the frame on your slab when it's level and sound and hang a screen door that closes right.
Patio cover installation
Plenty of backyards we see have no cover at all, or an old one sagging at the beam. We build a new cover sized to the slab, and if you think you'll enclose it later, we frame it now so it's ready.
Four season sunrooms
If you want a room you'll sit in morning and night, it needs insulated walls, a real roof and wiring, which is more than most patio covers were built for. We plan the insulation, glass and outlets up front, because adding them after the walls are closed costs you more.
What Rialto's ground and older patios ask of a sunroom
The city's own findings say two earthquake fault systems, San Jacinto and Rialto-Colton, run within its limits. That's said of the city as a whole, not of any one lot, but it's one more reason we don't cut corners on how the room ties to your house and what it stands on.
Most of the patios we see here were built for shade, not for walls. Older covers often hang off the house on a board at the eave that was never meant to carry glass, and slabs poured years ago can be thin at the edges or cracked where they meet the house. We check both before we build and fix the base first, because reinforcing a beam or pouring a footing later means taking the room apart to get to it.

How a Rialto sunroom job goes
You call and I visit
Call or send the form, and I set a time to come out to your house myself. It helps if you're there, because I want to hear what the room is for before I measure anything.
I measure and check the base
I measure the space, look closely at the slab or deck and give you a clear recommendation, including a no if it can't hold the room. You get a written estimate, so you know the cost before anything is filed or built.
We file with the city
We put together the plans and paperwork and file them with the city. The city's tentative estimate is that patio permits can often be reviewed and issued within 10 business days, counted Monday through Thursday, while other permits take about 20 business days of plan review and then about 10 more to be issued.
Our crew builds, I walk it
Our own crew builds in order so each stage is ready when the inspector comes, and we're there for every inspection. When it's done, I walk the finished room with you.
Rialto sunroom questions answered
How do I apply for a sunroom permit in Rialto?
Applications go through the city's Online Permit Center, and every permit needs a signed Declaration Form attached along with the ID of the person who signed it. When you hire us, we put together the plans and paperwork and file them, so you're mostly signing where it's needed.
How do I keep my Rialto building permit from getting held up?
Send in complete, correct plans the first time, because the city says corrections or revisions start its tentative 20-business-day review over again. That's why I'd rather settle the slab, the roof and the wiring before we file than change the plan halfway through review.
When does a contractor need a state license for a sunroom in Rialto?
California requires a contractor license to build or alter a structure when the project needs a building permit, uses employee labor, or has contracts totaling $1,000 or more in labor and materials. The state board does list exemptions, such as qualifying owner-builders. For a sunroom built under a permit, that means the person you hire should be licensed.
Is my home in Rialto in a fire hazard severity zone?
You find out by looking up your address, because zone status varies from one property to the next, and the city has a fire hazard severity zone page for that. The state fire marshal has issued recommended zone maps for San Bernardino County, and I check your address before we draw up plans.
How much does it cost to turn a patio into a sunroom in Rialto?
The cost comes down mostly to what's already there, so I give you a number after I've seen your patio, not before. A sound slab and a solid cover keep it lower, while new footings, a new roof, insulated walls, more glass and added outlets or lighting push it up. Your written estimate spells out which of those your job needs.
Can my existing patio slab in Rialto hold a sunroom?
Sometimes it can, and I'll tell you which on the first visit. A slab poured for patio furniture is often too thin at the edges or has no footing where the new walls would sit, so we either add footings or recommend starting fresh. I'd rather tell you no up front than build a room your slab can't hold.
