What does it take to turn a Fontana patio into a sunroom?
A patio-to-sunroom conversion in Fontana encloses the patio you already have and turns it into a room. That can be a simple enclosed patio, or it can be a heated and cooled sunroom that opens to the house and counts as living space. The planning and the city's review usually set the pace before any building starts.
Most people who call us have a covered patio out back that gets used now and then and swept the rest of the time. What it turns into decides the price, because the room type you pick sets much of the budget, and a larger room that needs a foundation plus heating and air conditioning sits at the high end of what people pay around here. Size, windows and whether we bring in electrical or heating and cooling move the price too. The schedule mostly turns on the city's plan review and on how much paperwork your room type adds. Your written quote spells out what's in the price and what isn't, so you see your own number before anything starts.
How we handle a patio-to-sunroom conversion
I start by asking what the room is for, a place to sit out of the dust or a room you'll live in, because that one answer sets the budget, the paperwork and the schedule. Then I look at the patio, how it meets the house and where the doors and windows should go, and we draw the room around how you'll use it. We put together the drawings for the city, and once the permit is in hand our crew frames the walls, sets the windows and the roof, and ties the room into the house. When the room needs power or heating and cooling, we bring in licensed trades for that part, and we clean up when we're done.
Some people come to us with a raised deck instead of a patio, and deck-to-sunroom conversion works through the same questions on a different base. If the answer to my first question is a room you'll live in year round, we'll talk about all season rooms, since that's the version built for everyday use.
Planning a patio-to-sunroom conversion in Fontana
Fontana Building & Safety reviews the plans against building, fire and safety codes, and the contractor has to sign the permit application and show a current California contractor's license, with every contractor and sub on the job showing proof of state and city licenses. We pull the permit in our name and handle the drawings, the inspections and the back and forth with the city, which is a lot of forms for a room that's mostly windows. The room type you pick changes what goes in. A heated or cooled room counts as new conditioned space, so the plans need energy forms or computer energy calculations. If the framing isn't conventional light wood framing, the city wants it designed by a California registered engineer or licensed architect, which adds a design step. And if your house has fire sprinklers, the new room needs them too, while a house without them needs both sprinklered once the addition is more than half the existing floor area.
Most of the patios we see here are covered spots off the back of the house, and the calls are usually about dust and getting more use out of the yard. We do the same work in Rialto and Rancho Cucamonga, and we deal with whichever city or county office covers your address.

What happens after you call about a patio conversion in Fontana?
Call us or send the form
Call (909) 346-1870 or use the form, and we'll set a time for me to come out. We pick up weekdays from 6 AM and weekends from 7 AM, until 9 PM.
Look at your patio together
I come out to look at the base, the house and how you want to 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 draw the room, pull the permit and set a schedule around the city's review, which Fontana says typically takes about 3 to 4 weeks the first time and about 2 weeks after amended plans go in. If the city asks for changes, we make them and that second clock starts.
Our crew builds the room
Our crew builds it once the permit is in hand. When it's done, I walk the finished room with you so you can point out anything that isn't the way you pictured it.
Why Fontana homeowners call Sunscape Fontana Sunrooms & Patios for a patio conversion
The owner does every estimate
I do the walkthroughs and estimates myself, and our own crew does the building. The person who heard what you want is the one answerable for the room you get.
Planning rooms since 2013
I ran the schedule for a busy construction company before I learned to build these rooms, and we've been at it since 2013. Every job is planned all the way through before anyone picks up a tool.
Licensed and fully insured
We're licensed and fully insured. If your plans touch the roof or the foundation, ask whoever you hire which license covers it, because the state's remodeling license doesn't cover structural changes to load-bearing parts.
We pull the Fontana permit
We don't ask homeowners to pull permits for our work, because the city's permit page warns that an owner who gets the permit while a contractor builds takes on the liability, taxes and personal injury included. That's ours to carry, not yours.
Most trouble on these jobs starts with a room two people pictured differently, and I'd rather sort that out at your kitchen table. Get in touch and we'll set a time.

Questions about patio-to-sunroom conversion in Fontana
How much does it cost to convert a patio into a sunroom near Fontana?
A three-season sunroom added to an existing structural base usually runs about $100 to $140 per square foot in the San Bernardino area, counting labor, standard-grade windows and electrical access. That figure leaves out insulation, extending heating or cooling, plumbing and pulling permits, so expect those on top. Our written quote lists each one so you can see where the money goes.
What is the difference between a four-season room and an enclosed patio?
A four-season room is generally fully enclosed, heated and cooled, with all-weather windows, while an enclosed patio generally has no heating or cooling and uses uninsulated windows or screens. One is a room you live in, the other is a covered spot you sit in when the weather's decent. In Fontana the heated version also brings the energy paperwork that new conditioned space needs.
Does Fontana require an inspection before plan check for a patio enclosure?
Yes, Fontana requires a pre-alteration inspection before any plans go in for plan check. It's a look at what's there now, before the city reviews what you want to build. We set it up as part of pulling the permit, so it's one less thing on your list.
How long does a patio-to-sunroom conversion take in Fontana?
Most of the waiting happens before we build, because the plans go through the city's review first and that runs several weeks, longer if the city asks for changes. A four-season room can add steps like energy calculations or an engineered design, so it can take longer to get approved than a simple enclosed patio. We set your schedule with the review already counted.
Can a patio cover company enclose my patio in California?
Not always, because the state's awning contractor license covers patio covers and specifically leaves out patio enclosures. A patio cover installer may need a different license to enclose your patio, so it's worth asking before you sign anything.
What causes a damp spot on a sunroom floor after rain?
One sunroom maker's guide says that when the slab is bigger than the room, the room is sealed straight to the slab, and a damp spot can show inside in wet weather. The maker says that isn't a structural problem. If your patio runs past where you want the walls, bring it up at the estimate and we'll talk it through.
