All season rooms in Santa Ana CA - a heated, cooled room you can use all year
Patio too hot in August and too cool at night? We plan and build a closed-in room, heated and cooled, for every season.

What is an all season room, and is it right for your house?
An all season room is a closed-in sunroom with its own heating and cooling, built so you can use it like any other room in your house on hot afternoons and cool nights. We plan and build all season rooms in Santa Ana, CA, and in many of the cities around it.
Most homeowners who call us have a patio they like but can't use on a hot afternoon or a cool evening, and they want a room they'll actually sit in. The first choice is whether the room opens into the house or stays closed off behind a door, because a room open to the house counts as living space, while a closed-off room with its own heating or cooling is treated as conditioned space that isn't living space, and the rest of the plan follows from that. The price moves with the room's size, whether it needs a new foundation and the heating and cooling you choose, and the schedule mostly turns on settling those choices and getting the plans approved by the city. When the room needs a permit, we prepare the plans, file with the city, meet the inspector and keep you posted along the way. At the estimate I measure, look at what the room would sit on and write up what the price covers, so you're working from your own figure and not a guess.
How we plan and build an all season room
We start outside, looking at where the room will sit and how water moves around that spot, because a base that sits low invites trouble. One maker's install guide says the foundation must sit higher than the ground around it, or standing water can get into the tracks and the room, so we plan for a slab or spot that stands above your yard. Next we note which windows of your house face the patio before we draw the layout. Another maker's paperwork lets the windows a room needs for light and air open into its enclosure, but if a bedroom window is that room's emergency escape opening, the patio stays unenclosed, and that's far better to learn now than after the frame is up. Then we settle the heating and cooling with you while it's still easy to change, and once the plans and parts are set, our own installers prepare the base, put up the frame, set the windows and doors, tie the room into the house and clean up.
Not every patio needs a heated, cooled room. If you mainly want shelter from wind and dust, an enclosed patio room closes it in without the heating and cooling, which is one of the bigger things that pushes a price up. If you'd rather have glass overhead as well as on the walls, we also handle solarium installation.
Why Santa Ana homeowners call Sunridge Santa Ana Sunrooms & Patios for all season rooms
I measure and plan it myself
I come out to look at the job and measure it myself, and our own installers do the build. I stay your contact from the first visit to the finished room, so you aren't explaining your plan over again to someone new.
Every choice settled before ordering
We've been in business since 2017, and we settle the base, the layout and the heating and cooling before anyone orders a part or cuts into your house. Changes are easy on paper and costly once the walls are up.
Licensed and fully insured, every job
We're licensed and fully insured, and we're glad to show you both at the estimate. It's your house being built onto, so you should know who stands behind the crew before work starts.
Santa Ana plan check papers prepared
The city's plan check asks for structural calculations, plus energy calculations where they apply, and the state wants an energy compliance record filed for most additions, so we put those together with your plans. That's paperwork you don't have to chase yourself.
On an all season room, the base and the layout decide most of what follows, so that's where we start. Call (657) 205-6766 or send us your details with the room's rough size, whether it will open to the house and which windows face the patio.
Get a free on-site estimate for your all season room
Estimates are free, on-site and come with no obligation, and we reply to every call and message within one business day. After you send the form, I'll set a time to come out, measure, look at what the room would sit on and write up what the price covers.
What an all season room looks like
Common questions about all season rooms
What makes a room an all season room instead of a three season room?
An all season room is fully enclosed with all-weather windows and is heated and cooled, so it's conditioned space you can use year-round. A three season sunroom or enclosed patio isn't heated or cooled and has screens or uninsulated windows. If you'd mostly use the room in mild weather, the three season room is worth pricing too.
How much does an all season room cost in Orange County?
Cost guides put a sunroom in Orange County at about $120 to $200 per square foot. Larger rooms that need a foundation and have heating and air conditioning sit at the higher end, and an all season room is heated and cooled by definition, so expect yours to lean toward the upper part of that range. Your estimate spells out what your own price covers.
Who issues building permits for a sunroom in Santa Ana?
In Santa Ana, the Building Safety Division issues construction permits once the plans submitted to the city are approved by every city department that applies to the project. If you have building questions before you plan the room, you can call the city's Building Division at (714) 647-5800. Preparing and filing those plans is the part we handle for you.
Who is allowed to build a sunroom in California?
California requires a Contractors State License Board license for anyone who builds or alters a structure when the project needs a building permit, uses additional workers or costs $1,000 or more in labor and materials. An all season room runs well past that $1,000 line, so ask any contractor you're considering to show you their license before you sign.
How do I find out if my Santa Ana house is in a flood zone?
You can look up FEMA flood maps by your address, and parts of Santa Ana are mapped in flood zones A and AE. We check where your house falls too, since the base and the way water moves around it are the first things we plan.
How do I keep sunroom windows and doors sliding smoothly?
One sunroom company advises keeping the door and window tracks clean inside and out and keeping the weep holes, the small drain openings in the frame, clear so water can get out. It suggests a pure silicone spray for the doors and windows, since oil-based lubricants tend to attract dirt.
