Four season sunrooms in Santa Ana CA - a room you can use every month of the year
Patio too hot in August and too cold in January? We plan and build an insulated sunroom you can use all year.

What is a four season sunroom, and is it right for your Santa Ana house?
A four season sunroom is an insulated room with its own temperature control that connects to the rest of your house, so in Santa Ana you can use it on a hot afternoon or a cool winter evening the same way you'd use your living room.
Most people who call us have a patio or a back room they'd like to use more of the year, and the first choice is how the new room joins your house. Some rooms get their own heating or cooling and keep your existing doors and windows, so the room stays separate from the house, and others are built like a regular room addition that opens right into it. That choice, along with the size of the room, whether it needs a new foundation, how it's heated and cooled and which frame and glass you pick, is most of what moves the price, and the schedule mostly turns on settling those choices and getting the plans through the city before anything is ordered. When the job needs a permit, we prepare the plans, file with the city and meet the inspector, and we 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 have your own figure to work from.
How we plan and build a four season sunroom
I start by measuring and looking at what the room would sit on, whether that's a slab, a deck or bare ground, because most trouble on these jobs starts with a skipped step like a weak base. Then we settle how the room joins the house and how it'll be heated and cooled, since those choices shape the framing, the wiring and the plans, and they're easy to change now and hard to change once parts are ordered. For a room you'll use all year I look closely at the frame and where it meets your wall, and if you're leaning toward aluminum, we talk about frames built to stop heat and cold from moving through the metal. Once you've signed off on a plan that spells out what the room includes, we build it to that plan and clean up when it's done.
Not every house needs a fully heated and cooled room. If you'll mostly use the space on mild days, three season sunrooms are a simpler build, and if you already have a covered patio you'd like walled in, our patio enclosures work with the structure you have.
Why Santa Ana homeowners call Sunridge Santa Ana Sunrooms & Patios for a four season room
I measure and stay your contact
I come out to look at the job and measure it myself, our own installers do the build, and I stay your contact from the first visit to the finished room. You won't have to explain your plans twice to people who never talked to each other.
Building rooms here since 2017
I spent years running the schedule for a busy remodeling company and saw how jobs fall apart when one step gets rushed, then started this business in Santa Ana in 2017. That's why we plan the whole room before anyone orders a part or cuts into your house.
Licensed and fully insured builder
We're licensed and fully insured. When you compare contractors, it helps to know the state licensing board describes the B General Building contractor as one who works on structures using at least two unrelated trades, and a four season room usually brings in framing, electrical and heating and cooling.
Planned around Santa Ana energy rules
Santa Ana requires all residential construction to meet California's building energy efficiency standards, known as Title 24, so we settle the windows, insulation and heating and cooling while the plans are drawn. That way the room you sign for is already built around those rules instead of being reworked later.
On a room you'll use all year, what it sits on and how it's heated and cooled matter most, so those are the first things I'll look at. Request your estimate with your address, the room size you have in mind and whether it would sit on an existing deck, or call (657) 205-6766 or email hi@santaanasunroomsandpatios.com.
Get a written estimate for your four season sunroom
We reply to every call and message within one business day, and the on-site estimate is free with no obligation. I'll set a time to come out, measure, look at what the room would sit on and write up what the price covers. If you tell us your address, the room size and whether there's a deck involved, I can come ready.
Ideas for a year-round sunroom
Questions before you book a four season sunroom
How much does a four season sunroom cost in Orange County?
A sunroom in Orange County usually costs about $20,000 to $120,000 per project, and that's the area's going range, not our price. Larger rooms that need a foundation and have heating and air conditioning sit near the high end, and a four season room usually has heating and cooling. Call (657) 205-6766 to get a figure for your own house.
Who issues building permits for a sunroom in Santa Ana?
The city's Building Safety Division issues building, electrical, plumbing and heating and cooling permits, and it also reviews plans and inspects the work. For most applications the Planning Division approves the project first, and construction permits follow once the city approves the plans. Parts of Santa Ana are in FEMA flood zones, so it's worth looking up your address on FEMA's flood maps at msc.fema.gov before the plans are drawn.
Can a sunroom go on my existing deck?
It can, but the deck will typically need extra beams, posts or footings, the bases the posts stand on, to carry the added weight. The national sunroom trade group advises asking a local structural engineer whether the deck is suitable, which is worth doing early because the answer can change the plan and the budget. I look at your deck before we plan on it.
What frame materials resist heat transfer in a four season sunroom?
Wood and vinyl frames resist heat transfer on their own, while one builder's guide says aluminum needs a thermal break, a strip of material that doesn't conduct heat set between the metal pieces. If you're comparing aluminum rooms, ask whether the frame is thermally broken, since that also keeps condensation from forming inside.
How do I compare windows for a four season sunroom?
Compare two ratings, the U-factor and the solar heat gain coefficient. A lower U-factor means the window insulates better, and a higher solar heat gain coefficient means more of the sun's heat comes through, so on a sunny wall you'll usually weigh insulation against how much afternoon heat you want in the room.
How do I know if my Santa Ana sunroom needs a Title 24 energy report?
Most major residential projects in Santa Ana need a Title 24 energy report from certified energy professionals, while minor projects may be able to follow set prescriptive requirements using forms filled out by the homeowner or designer. Which path your room takes depends on the project, and we'll find out when we prepare the plans.
Other rooms and enclosures we build
- Three season sunrooms
A lighter choice if you'll mostly sit out there on mild days and don't need a full heating and cooling setup.
- Patio enclosures
Makes sense when your covered patio is already in good shape and you want walls and windows around the space you have.
