Is an all season room the right fit for your Fontana home?
An all season room in Fontana is a fully enclosed room with all-weather windows that's heated and cooled, so the patio or deck you only use in spring becomes a room you can sit in through a July heat wave or a cold January night.
Most people who call us have a patio or deck that sits empty half the year because it's either baking or chilly out there. The price mostly comes down to the room's size, whether it needs its own foundation, the heating and cooling, and how well the walls, floor, roof and windows are insulated. The schedule mostly comes down to the city's plan review, not the building, and we handle the drawings and the permit so that part isn't on you. If an unheated room would suit you most of the year, a three season sunroom can make more sense. Either way, I'll give you a written quote that spells out what's in the price and what isn't.
How we build an all season room
The first thing I settle with you is whether the room opens to the house or closes off with its own controls, because that choice shapes the walls, the heating and cooling and the whole build. The industry's sunroom specification covers both kinds, but it only defines the room that's open to the house as habitable, so you're really choosing between a separate space and more living area. Next we plan the insulation for the walls, floor and roof and pick the windows, since those are much easier to get right while the room goes up, and adding them later often costs more. Our crew sets the base, frames the walls and roof and installs windows meant to keep out air leaks and water, which is what that same specification asks of these rooms. Then come the electrical and the heating and cooling, the inside finish work and the cleanup.
If you want walls and glass around the patio without heating and cooling it, an enclosed patio room is the lighter version of this job. If the whole point is light, with glass running up into the roof, look at our solarium installation work, and we'll talk through how much sun you actually want in a Fontana summer.
All season room permits and planning in Fontana
The city's Building & Safety office reviews permit plans in Fontana. Its list of jobs that need extra drawings names room additions and new construction but doesn't mention all season rooms by name, so whether your room needs a permit is a question for that office, and it's one we take to them for you. When a job needs a permit, we pull it in our name as the contractor and handle the drawings, the inspections and the back and forth with the city. We're based in Fontana, and outside the city we deal with whichever city or county office covers your address.
Most rooms we're asked to build here go on an existing patio slab or deck, and plenty of those were built for a table and chairs, not walls and a roof, so I check the base before anything gets drawn. We see the same thing on jobs in Rialto and Rancho Cucamonga, along with long, hot summers that make the cooling and any west-facing glass worth planning carefully.

What happens after you call about an all season room
Call or send the form
Call (909) 346-1870 or send the form, and we'll set a time for me to come out. Your address and a rough idea of the room is plenty to start.
I look at the base
I look at your slab or deck, how the room would tie into the house and how you want to use it, and we decide whether it opens to the house or closes off. You get a written quote that says what's in the price and what isn't.
We handle drawings and permit
We draw the room, pull the permit and set a schedule that already counts Fontana's first plan review, which typically takes about 3 to 4 weeks. If the city asks for changes, each later review typically takes about 2 weeks after amended plans go back in.
Our crew builds, we walk it
Our crew builds the room from the base up. When it's done, I walk through it with you so you can see it works the way you pictured.
Why Fontana homeowners call Sunscape Fontana Sunrooms & Patios for all season rooms
I do every estimate myself
I do the walkthroughs and estimates, our own crew does the building, and we bring in licensed trades for electrical or heating and cooling work. The person who agreed with you on a room that opens to the kitchen is the same one checking that it does.
Licensed and fully insured, California rules
We're licensed and fully insured. California's Contractors State License Board requires a license in certain cases, including when a job needs a building permit, uses additional workers or runs $1,000 or more in labor and materials, which takes in just about any all season room.
Planned all the way through since 2013
We've been building since 2013, and before that I spent years running the schedule for a busy construction company. That's why the hard questions about price, permits and how the room will work get asked at your kitchen table, not halfway through the build.
The big decision on this job gets made before anyone builds anything, so let's make it together. Set up your estimate or call (909) 346-1870.

Questions about all season rooms in Fontana
How do I choose between an all season room and a three season room?
Choose an all season room if you want to use it every month, because it's fully enclosed with all-weather windows and it's heated and cooled. A three season room or enclosed patio has screens or uninsulated windows and no heating or cooling, so in Fontana it's pleasant in spring and fall and a lot less so in July. If you'll mostly use it on mild evenings, the simpler room usually makes more sense.
How much does an all season room cost in Fontana, CA?
A sunroom in the San Bernardino area usually costs about $16,000 to $115,000 per project, and that range covers sunrooms in general, not just all season rooms. Larger rooms that need a foundation and have heating and air conditioning fall toward the high end, which describes a lot of all season rooms. Your written quote shows what your room includes.
How long does it take to build an all season room in Fontana?
Usually the longest stretch is the city's plan review, not the building, and we count that review into the schedule before we set a start date. Time on site depends on the room's size, the base and the heating and cooling, and we set that schedule with you once the drawings are done.
Who should pull the permit for a sunroom in Fontana?
Your contractor should. The city of Fontana warns that when the contractor doing the work asks the owner to get the permit, the owner takes on liability for the project, including taxes and personal injury. We pull permits in our name and don't ask homeowners to pull them for our work.
Does an all season room have to meet California's energy code?
It does when the room counts as an addition, because the state Energy Code sets energy and water efficiency requirements for additions to existing buildings. The industry sunroom specification also ties the energy performance of a heated or cooled sunroom's roof, walls, windows and doors to the energy code or local codes, so we work that into the drawings.
How do I find out if my Fontana home is in a fire hazard zone?
You can look up your area on the Fire Hazard Severity Zone map the city publishes from the State Fire Marshal. It's worth a look before anything gets drawn, and I'm happy to pull it up with you at the walkthrough.
