What goes into adding a sunroom to a Fontana house?
A sunroom addition is a one-story room attached to your house, with glass making up more than 40 percent of its outer walls and roof. Sunscape Fontana Sunrooms & Patios builds them in Fontana so a sunny patio or deck becomes a room you actually use.
Most people who call us have a slab or a deck out back that bakes in the afternoon and sits empty, and they want a real room there instead. If you're starting from a covered slab, our patio-to-sunroom conversion page covers that version of the job. Price comes down to how big the room is, what it sits on and whether it gets heating and air conditioning, because a larger room that needs a foundation and its own heating and cooling lands at the high end. The schedule mostly turns on drawings and the city's review rather than the building, and the written quote from my visit spells out what's in the price and what isn't.
How we plan and build a sunroom addition
The first question is whether the room works like the rest of the house or stays a glass room you don't heat or cool, and we settle that before we draw anything because it changes what goes into the plans. The sunroom trade group sorts rooms along that line, from glass rooms with no heating or cooling at all up to one that's basically a regular room addition. There's a middle option too, a room with its own heating or cooling where your existing doors and windows stay in place and keep the room's temperature separate from the house. Once that's decided, we check what the room will sit on, draw it, get it through the city, and our own crew builds it, with licensed trades brought in for electrical or heating and cooling work when the room calls for it.
If you already know you want a room you'll use in August and January alike, our four season sunrooms are the heated and cooled version. If light and shelter without heating or cooling suits you better, look at our three season sunrooms.
Getting a sunroom addition approved in Fontana
Fontana treats a sunroom like any other addition to your house, and the city requires a pre-alteration inspection before any plans go in for plan check, so we book that inspection first, before the plans are drawn, which is what the city recommends. The contractor signs the permit application, and we pull the permit in our name and handle the drawings, the inspections and the back and forth with the city. If your house has fire sprinklers, the addition needs them too, and if it doesn't but the addition is more than half your existing floor area, both the house and the addition have to be sprinklered. When the room isn't conventional light wood framing, the city wants the structural design done by a California registered engineer or licensed architect, and we line that up as part of the drawings.
Most rooms we add around Fontana go on the back of single-story stucco houses, over an existing slab or a raised deck, facing the kind of afternoon sun that makes the heating and cooling question a real one. We see the same houses and the same heat 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 sunroom addition
Call or send the form
You call (909) 346-1870 or fill out the form, and we set a time for me to come out. I look at what the room would sit on, the house and how you want to use the room.
Get your written quote
You get a written quote that says what's in the price and what isn't. The heating and cooling question and any deck concerns are settled before that quote, not after.
We handle drawings and permit
We draw the room and take it through the city, and Fontana's first plan check usually takes about 3 to 4 weeks. Your schedule already counts that wait, which is the dullest part of the job and the one that moves the date most.
We build, then walk it
Our crew builds the room and keeps the site cleaned up as we go. When it's done, I walk the finished room with you.
Why Fontana homeowners call Sunscape for sunroom additions
The owner does every estimate
I do the walkthroughs and estimates myself, so the person answering your questions about decks, heating and the city is the one who'll answer for it later. You won't get one story from a salesperson and another from the crew.
Building and scheduling since 2013
We've been in business 13 years, and before that I ran the schedule for a busy construction company. A good schedule is half this job, especially with a city review sitting in the middle of it.
Licensed, insured, and happy to show it
We're licensed and fully insured, and Fontana asks every contractor and subcontractor on a job to show proof of state and city licenses. Ask to see ours at the estimate, because it's the easiest check you'll make all project.
If you'd rather have the hard conversations at your kitchen table than halfway through framing, ask for a visit.

Questions about sunroom additions in Fontana
How much does a sunroom addition cost near Fontana?
A sunroom in San Bernardino usually costs about $100 to $190 per square foot, and those are San Bernardino figures, not Fontana ones. One estimate there covered labor, standard-grade windows, siding, roofing, fixtures and electrical access but left out insulation, extending heating or cooling, plumbing and permits, so ask any contractor which of those their quote includes. Ours spells it out in writing.
Can a sunroom go on my existing deck?
Often it can, but the sunroom trade group says a deck will typically need extra beams, posts or footings to carry the added weight and loads. A local structural engineer can say whether your deck is suitable, and we get that answer before we price the room.
Does heating or cooling a sunroom change the rules in California?
Yes, because California Energy Commission guidance says a space that goes from unheated to heated or cooled has to meet the requirements for an addition. That's why we settle heating and cooling before anything is drawn, so the plans are right the first time instead of reworked later.
How long does it take to add a sunroom in Fontana?
Most of the calendar goes to the front end, meaning the pre-alteration inspection, the drawings and the city's plan check, while the build itself depends on the room's size and what it sits on. We give you a schedule with the city's review already counted in, so the date you hear is one we planned for.
How do I take care of a sunroom so it lasts?
Check the roof and gutters once a year and keep the weep holes clear so water drains out, which is what one sunroom maker's guide suggests. The same guide advises keeping door and window tracks clean and smooth with pure silicone spray.
Should I pull the permit myself or have my contractor do it in Fontana?
Let the contractor pull it, because the city says an owner who gets the permit for a contractor's work takes on the project's liability, such as taxes and personal injury. We pull permits for our work in our name and don't ask homeowners to do it. If you're building it yourself with no contractor, you sign as Owner/Builder and complete the city's owner/builder certification.
