Is a four season sunroom right for your San Clemente home?
The short answer: A four season sunroom is a fully enclosed room with all-weather windows and real heating and cooling, so you can sit in it on a chilly winter night or a hot August afternoon like any other room in your house. San Clemente Sunrooms and Patios builds them in San Clemente and the cities around it in south Orange County.
Most people who call us already have a patio or deck they like and just want to use it more than a few months a year. What moves the price is the size of the room, what it sits on, whether it stays closed off or opens into the house, and how much glass, insulation and heating and cooling go into it. The schedule turns on the permit and the city's plan check, plus any work the base needs before we can frame, like shoring up an old deck or leveling an uneven slab. The estimate gives you a written plan for your room, so you're deciding on your own house and not on a guess.
How do you know your patio is ready to become a four season room?
Patio empty half the year
You use the patio or deck all summer, but on cool evenings and damp mornings nobody goes out there. That usually means the space needs walls, real glass and heat rather than another umbrella, and every season you wait is one more you don't get to use it.
Screen room too hot or cold
Your screen room or older enclosure bakes in the afternoon sun and goes cold after dark. Screens and uninsulated glass can't hold heat in or keep it out, so putting off the change usually means paying for fixes that never touch the real problem.
House feels a room short
You need a spot for an office, a guest or a quiet chair, and a full addition feels like more house than you want to build. A four season room can live like any other room, and the longer you wait, the longer you keep working around the crowding.
How we build four season sunrooms
The first thing I settle with you is whether the room stays closed off from the house or opens into it like any other room, because that choice shapes the windows, the insulation, the heating and cooling and how the roof ties in. Then we check what the room will sit on, whether that's an old slab, a deck or bare ground, and fix the base before anyone frames a wall, the same way a good night in a kitchen starts with the setup. From there our crew frames the walls and roof, sets the windows, insulates the walls, floor and roof, brings in the heating and cooling and finishes the inside so it reads as a real room. We clean up as we go, because a cluttered site is where mistakes hide.
Not every patio needs a fully heated room. If you mostly want to sit out of the wind in spring and fall, a three season sunroom skips the heating and cooling, and patio enclosures close in a covered patio you already have. I'll tell you straight which one fits the way you'll actually use the space.
Closed off, with its own heating and cooling
Your existing doors and windows stay where they are, so the room is sealed off from the house and runs on its own heating and cooling. It suits a room you'll use as a retreat, and it keeps the work on your house wall to a minimum.
Opened into the house like an addition
We build it essentially the same as a regular room addition and open it up so it flows into your living space. If you'll treat it as part of the living room, I'd build it this way from the start rather than pull out a slider later.
What happens when you call about a four season sunroom in San Clemente?
Here's how a four season room goes from a first call to a finished room, and who you'll be dealing with at each step along the way.
- Step 01
Call or send a message
Call (949) 312-6032 or send the form, and we'll get back to you to set a time for me to come out. We work around your schedule, evenings and weekends included.
- Step 02
I look and write a plan
I look at what the room will sit on and ask how you want to use it, especially whether it should open into the house. Then I write up a plan you can read over before you decide anything, so the price isn't a mystery.
- Step 03
Permit, build and walkthrough
Once you say go, we handle the permit side and prep the site before our crew builds the room. I check the work as it goes up, right through the final walkthrough with you.
Building a four season sunroom in San Clemente
A sunroom addition goes through the city's Building and Safety Division, which handles permits for additions, checks the plans and inspects the work so it meets the building codes the city has adopted. Either a California licensed contractor or an owner doing the work under an Owner Builder permit can pull it there. We plan on a permit for these rooms, pull it as your licensed contractor, prepare what the city asks for and meet the inspector when they come out.
Before the design is final, the city's Planning Division says to check with Planning or Building, because its requirements may change what you can build. That matters near the water, since the Coastal Zone generally runs inland to Interstate 5 and the city's Local Coastal Program applies only there, and it matters east of the freeway in neighborhoods like Talega and Forster Ranch, whose Specific Plans set their own standards and design guidelines. We work that check into the plan, and we see the same mix of older homes near the coast and newer planned neighborhoods inland on jobs in Dana Point and Rancho Mission Viejo.

Why San Clemente homeowners call San Clemente Sunrooms and Patios
The owner plans and checks it
I come out for the estimate and plan your room myself, then our crew builds it while I check the work along the way. The person who heard how you want to use the room is the one making sure it gets built that way.
Nine years on awkward jobs
I started this business in San Clemente in 2017, and we're best known for the awkward jobs, like an old deck, an uneven slab or a wall that takes the full afternoon sun. Those are often exactly where a four season room wants to go, so it helps to have a crew that gets curious about them instead of put off.
Your licensed contractor on the permit
We're licensed and fully insured, and we act as the contractor on your permit so you don't have to. The city strongly discourages owners from becoming their own contractor, because they take on the liability for bad work by anyone they hire.
On a four season room, the base and the first plan decide how the room holds up, so that's where I spend the time. Your satisfaction, guaranteed. Set up your estimate and I'll come take a look.
Four season sunroom questions from San Clemente homeowners
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 job, and that range covers sunrooms in general. Larger rooms that need a foundation and have heating and air conditioning sit at the higher end, which is where many four season rooms land. Your own figure comes from the estimate, once I've seen what the room will sit on.
What is the difference between a four season and a three season sunroom?
A four season room is fully enclosed, heated and cooled, with all-weather windows, while a three season room has no heating or cooling and uses uninsulated windows or screens. That's why only the four season room works as a year-round room in your house.
Do I need a building permit for a sunroom in San Clemente?
Plan on one, because the city says most projects require a building permit. We work the permit into the schedule from the first plan, so it isn't a surprise once you're ready to build.
How do I know if my deck can hold a sunroom?
A sunroom built on an existing deck will typically need more beams, posts or footings to carry the added weight, according to the national sunroom trade group's guidance. I look under the deck at the estimate and put that structural work into the plan and the budget up front, so don't rule your deck out before someone checks it.
What is the best way to insulate a four season sunroom?
Insulate it while it's being built, because highly insulated windows and insulation in the walls, floor and roof are much easier to put in then. Adding them later can often cost more, so we settle those choices in the first plan.
What energy rules apply to a heated and cooled sunroom?
A national sunroom trade group's guide says sunrooms with heating or cooling are required to meet the International Energy Conservation Code. That's one more reason we settle the windows, insulation and heating and cooling before the build starts.

Three season sunrooms
If you mostly want a sheltered spot for spring and fall evenings, a three season room with screens or simpler glass keeps out wind and bugs without heating.
Patio enclosures
If you already have a solid patio cover you like, enclosing the sides can turn it into usable space without starting over on the roof or the slab.
