What goes into a custom sunroom in Fontana?
A custom sunroom in Fontana is an enclosed room added onto your house, usually over an existing slab or deck, with the windows, walls, roof and electrical laid out to fit your home instead of a stock size from a catalog.
Most people who call us have a patio or deck that's too hot, too windy or too dusty to use much, and they want a room there instead. The price moves with the size, with whether you want a room you heat and cool or a simpler three-season room, and with whether your slab is sound or has to be replaced. The schedule mostly turns on the city's review, which we count from the first day. I'll give you your own figure after I've seen the base, in a written quote that says what's in it and what isn't.
How we build custom sunrooms
Custom means the room fits your house, not a catalog. I measure the base, the roofline and the doors you'll actually use, because those decide where the room ties in, how the roof can pitch and where you'll walk in from the kitchen. We settle early whether it's a room you heat and cool or a simpler three-season room, since that choice changes the windows, the insulation and the paperwork. Then we draw it, get it permitted, and our crew builds it in the order the plan sets, so nothing gets torn out because a step came too early.
If you already have a design and just need a crew to put it up, that's our sunroom construction work. If the room you've got is the problem, an older one that leaks or bakes every afternoon, sunroom remodeling is where we'd start.
Custom sunroom permits and rules in Fontana
In Fontana, the city wants a pre-alteration inspection of your house before any plans go in for plan check, and the contractor signs the permit application, so we set up that inspection and sign as the contractor ourselves. A bigger room, or one you heat and cool, brings more with it. If the design goes past ordinary light wood framing, the city wants it designed by a California registered engineer or licensed architect, and new heated or cooled space needs energy calculations in the submittal. Sprinklers catch people off guard. If your house has fire sprinklers, the addition gets them too, and if it doesn't but the addition is more than half your existing floor area, both get sprinklered. The paperwork sometimes has more steps than the framing, which is why I'd rather tell you at your kitchen table which of these your room triggers.
Most of what we build here goes onto existing patio slabs and wood decks behind stucco houses, and plenty of those slabs have settled or cracked over the years, so the base is the first thing I look at. We see the same houses and the same patios on jobs in Rialto and Rancho Cucamonga, and we deal with whichever city or county office covers your address.

What happens after you call about a custom sunroom in Fontana?
Call or send the form
Call (909) 346-1870 or fill out the form, and we'll set a time that suits you. I come out myself, not a salesperson.
I look at your base
I check the slab or deck, the roofline and the doors, and we talk about how you'll use the room. You get a written quote that says what's in the price and what isn't, so the extras don't show up later.
We handle drawings and permit
We do the drawings, deal with the inspections and work the permit through the city. The schedule we give you already counts the city's review, so nobody's waiting on paperwork they didn't plan for.
Our crew builds the room
Our own crew builds it to the plan. When it's done, I walk the finished room with you.
Why Fontana homeowners call Sunscape for custom sunrooms
Planned through since 2013
I ran the schedule for a busy construction company before I built rooms myself, and we've been doing this since 2013. The plan, the permit and the order of work are settled before anyone picks up a tool, so you aren't surprised halfway through.
The owner does your estimate
I do the walkthroughs and estimates myself, and our own crew does the building. The person who told you what the room would be is the same one who walks it with you at the end.
Licensed and fully insured here
We're licensed and fully insured, and Fontana asks every contractor and subcontractor on a permit to show a current California State contractor's license and a city license. When a room needs electrical or heating and cooling work, we bring in licensed trades, so every name on your permit checks out.

Questions about custom sunrooms in Fontana
How much does a custom sunroom cost in Fontana?
Adding a three-season sunroom onto an existing base in the San Bernardino area usually costs about $100 to $140 per square foot, labor included. That usual figure leaves out insulation, extending your heating or cooling, plumbing and pulling permits, so a room that needs those runs higher. Your written quote spells out which of them are in your price.
What is the difference between a three-season and a four-season sunroom?
In the regional cost guides, a four-season room is heated and cooled and has all-weather windows, while a three-season room has no heating or cooling and uses uninsulated windows or screens. So the real choice is between a room you heat and cool and a simpler enclosed patio or porch.
Why does a heated and cooled sunroom cost more?
Larger sunrooms that need a foundation and have heating and air conditioning fall at the higher end of local price ranges. An industry sunroom specification treats a heated or cooled room that's open to the house as a habitable room, and its windows have to meet air leakage, water and thermal requirements. In Fontana it also brings the energy paperwork mentioned above.
How do I plan a sunroom so I can heat and cool it later?
Plan the insulation at the start, because insulated windows and insulation in the walls, floor and roof are much easier to install while the room is being built. Adding them later can often cost more. If there's any chance you'll want the room comfortable in every season, tell me at the first visit and we'll design for it.
Can a sunroom go on my existing patio slab?
Sometimes, if the slab is in like-new condition. One maker's installation guide prefers a new slab or deck, and says numerous buckles or cracks make a slab unsuitable and could contribute to leaks later. I check your slab on the first visit and tell you plainly whether it'll carry the room.
Should I pull the permit for my sunroom myself or let the contractor do it?
Let the contractor pull it. Fontana warns that an owner who gets the permit for a contractor's work takes on liability for the project, including taxes and personal injury. We pull it in our name as the contractor, and we never ask homeowners to pull permits for our work.
