Fontana: older ranch homes and newer tracts
Fontana is mostly houses, and on our jobs we see two kinds. The older single-story homes, many on the side of the city that runs toward Bloomington, tend to have deeper lots, a concrete patio someone poured decades ago and sometimes a patio room or cover that's been added onto more than once. The newer subdivisions farther north have tighter backyards, a builder's slab off the slider and neighbors close on every side, which feels a lot like the newer streets over in Rialto.
That split shapes the job. On an older house I'm checking whether the old slab and the old roofline can carry a new room, and on a newer one the size of the yard and the layout of the back wall usually decide how big the room can be.

Sunroom work we do in Fontana
Patio-to-sunroom conversion
Plenty of Fontana backyards already have a covered concrete patio, so we start by checking whether that slab is level and solid enough to carry walls and glass. If it is, we build on it, and if it isn't, I'll tell you what it needs before we talk about anything else.
Four season sunrooms
When you want a room you'll sit in all year, a four season sunroom with an insulated roof, walls and glass is the one to build. We tie it into the house so it feels like part of the home, which matters most on the newer tracts where the back yard doesn't have a foot to spare.
Sunroom remodeling
A lot of older Fontana homes have a sunroom or patio room someone added years ago, and by now the panels leak, the screens are torn or the roof sags. I'll tell you plainly whether it's worth fixing or better taken down and rebuilt, because sometimes patching it costs you more in the long run.
Patio enclosures
If you like your patio cover and just want it closed in, we can add walls, windows and a door to make it a room for the kids, the dog or the dinner table. We check the posts and beams first, because a cover built only for shade isn't always ready to hold walls.
Patio cover installation
Some Fontana yards are bare concrete or dirt off the back door, and a patio cover is the simplest way to make that space usable. We size and place it so it can be closed in later if you decide you want a full room.
Screen room installation
A screen room gives you a spot to sit out back with the bugs kept out, without the cost of glass. We build it on your existing slab when the slab is sound, and we frame it so windows can go in later if you change your mind.
What we know about building sunrooms in Fontana
If your house is inside Fontana's city limits, the city's Building & Safety takes the building permit application, and if it sits in one of the unincorporated areas with a Fontana address, San Bernardino County handles it instead. That's why the first thing we do on a Fontana job is confirm which office your address belongs to, and when the job calls for a permit we take care of the paperwork with that office, so permit review often sets the start date more than our own schedule does. You can also check any contractor the way the city does, because Fontana requires every business working in the city to hold a city business license, even one based elsewhere like we are.
Fontana is a short drive from our base in Bloomington, and it's the same work we do in Rancho Cucamonga and Jurupa Valley. The price moves with the size of the room, how closed-in you want it, how much work your slab or deck needs and how the new roof ties into your house, and the schedule turns on the permit and on when the windows and panels arrive. I come out for the estimate myself so you get a figure for your own house, and our crew does the building with me checking the work as it goes.

Sunroom and patio ideas for Fontana homes
Sunroom questions from Fontana homeowners
Do I need a building permit for a sunroom in Fontana?
Fontana's Building & Safety is the office that can tell you what your project needs, since it takes the building permit applications in the city. Its counter is at 8353 Sierra Avenue, open Monday through Thursday and closed Fridays, and the phone is (909) 350-7640. When we take your job, we check this first and handle the paperwork if a permit is called for.
Who can sign for a building permit in Fontana?
Once the fees are paid, only the signing contractor on record or the property owner can sign for a Fontana permit, and anyone else needs written permission notarized by one of them. The city also says an owner who pulls a permit for a contractor's work takes on the liability for the project, including taxes and personal injury. That's a good reason to have your contractor pull it, and it's why we do.
Does a contractor from another city need a Fontana business license?
Yes, Fontana requires every business working in the city to have a city business license, even when it's based somewhere else. It costs $35 to apply and $15 a year to renew, plus a yearly business tax based on estimated gross receipts, and the license runs one year from the day it's issued. Ask any contractor you're considering whether theirs is current.
How do I apply for a building permit online in Fontana?
The city asks applicants to set up an account on the Build Fontana Public Portal, and Building & Safety now takes payments online for a fee of 3% plus $0.20 per transaction, or a flat $3.00 if you pay by bank transfer. If you just bought the house, you'll need proof of ownership with the application.
How long does it take to get a sunroom permit in Fontana?
Most of the wait is plan review, and it runs longer if your project also needs a fire permit, since Building & Safety sends those to the Fire Department, which reviews the plans and issues the fire permit once they're approved. I'll tell you at the estimate whether I expect any of that on your job, so you're not guessing at a start date.
How much does a sunroom cost in Fontana, CA?
The price for your house comes down to a few choices, mainly the size of the room and whether you want screens, single-pane windows or a fully insulated four season room. Fixing or replacing an old slab, adding outlets, lights or a fan, and the permit fees add to it, while building on a sound existing patio usually keeps it down. I go over each of those with you at the estimate so you can see what's driving the number.
