What goes into adding a sunroom to my house?
A sunroom addition in San Juan Capistrano is a new enclosed room with windows or screens, built onto your house. It turns a patio or deck you hardly use into a room you'll actually sit in, and some types are heated and cooled so you can use them in every season.
Most people who call us have a patio slab or a deck out back that's too hot, windy or buggy to use much, and they want a real room there instead, sometimes as a patio-to-sunroom conversion. The price mostly moves with the size of the room, whether it's heated and cooled, what tops it and whether it can sit on what you have or needs a new foundation. The schedule turns on the city permit, any HOA approval and how much has to be built before the room goes up. Your written estimate spells out the room type, the roof and what's included, so you can see where the money goes before you decide anything.
How we build a sunroom addition
On an addition I talk about the roof before almost anything else, because the roof of a new room soaks up more summer sun than any of its walls. On a midsummer day a square foot of roof can take in about three to four times the sun of a square foot of north- or south-facing wall, so what tops the room decides a lot about whether you'll want to sit in it in the afternoon. Once the roof and the room type are settled, we check what the room will sit on, get the base ready, frame the walls and roof, set the windows or screens, tie the room into the house and clean up when we're done.
The next big choice is whether the room gets heating and cooling. We build four season sunrooms for people who want a room they'll use all year, and lighter three season sunrooms for people who mostly want shade and a spot out of the wind, and the questions further down cover the difference.
What the city checks before a sunroom addition in San Juan Capistrano
The city requires a building permit, with some exceptions, anytime a structure is built, enlarged or altered, so we plan on one for an addition. If your home is in an HOA, the city wants written HOA approval before it issues a permit for any work on the outside of the house, windows and doors included, which means a copy of the approval letter or HOA stamped plans has to be in hand by the time the permit is issued. Projects with grading and visible site improvements also need the Planning Department's approval first. You can look up your lot on the Orange County Fire Authority High Fire Hazard Zone Map from the city's interactive maps page, which is a good check to make before building. We handle the permit paperwork and the city appointments for you.
We're based in San Juan Capistrano and work in the cities around it across Orange County. A room is only as solid as what's under it, so on every job I look over the old slab, deck or cover before we talk design, and we see the same kinds of back patios on jobs in Mission Viejo and San Clemente.

What happens when you call San Juan Capistrano Sunrooms and Patios?
Call or send a message
Call (949) 312-6067 or use the form, and we'll set a time for me to come out. It helps to tell us what's out back now, whether that's a slab, a deck or a cover.
I measure and ask questions
I come out myself to see the space, measure it and ask how you want to use the room. I also look over what the room would sit on, since that shapes what it can be.
Go over your written estimate
You get a written estimate that spells out the room type, the roof and what's included. We go over it together until every line makes sense, and I'll answer the same question twice if that's what it takes.
We permit, build and walk through
Once you say go, we take care of the paperwork and our own crew builds the room while I check the work as it goes. When it's finished, I walk through the room with you.
Why San Juan Capistrano homeowners call us for sunroom additions
The owner comes out to measure
I come out myself to look at the space, measure and answer your questions, and I'm on site checking the work while our own crew builds. You talk to the person responsible for your room from the first visit to the last.
Raised on job sites, building since 2023
I grew up on my dad's job sites carrying glass and sweeping slabs, and I started this business in 2023 to build rooms the way he taught me. He explained every job before he built it, and we still explain every option before anyone signs.

We're fully licensed and insured. An addition becomes part of your house, so you want the people building it properly covered.
HOA paperwork put together first
If your home is in an HOA, we help you put together what it asks for before anything goes to the city. Here the HOA's written approval has to come before the permit, so getting it early keeps the job from stalling.

Questions about sunroom additions in San Juan Capistrano
How much does a sunroom addition cost in Orange County?
A sunroom in Orange County usually costs about $120 to $200 per square foot, and that's the going range for the room itself, not a quote from us. Larger rooms that need a foundation and come with heating and air conditioning sit at the high end. Your own figure comes in the written estimate after I measure the space.
What is the difference between a three-season and a four-season sunroom?
A four-season room is generally fully enclosed, heated and cooled, with all-weather windows, while a three-season room generally isn't heated or cooled and has uninsulated windows or screens. Conservatories and solariums fall on the four-season side, and enclosed patios on the three-season side. A screened porch or patio is lighter still, with screens only and no windows or heating and cooling.
How do I decide whether my sunroom should be heated and cooled?
Decide by how you'll use the room, because heating or cooling it is what makes it a year-round room instead of a lighter three-season build. In California it also changes the rules, since the state's Energy Code treats heating or cooling a space that wasn't conditioned before as an addition. If you want to sit out there on winter evenings and hot afternoons, I'd lean toward conditioning it, and if it's mostly a shaded spot for mild days, a lighter room is often the better buy.
What should a sunroom contract include in California?
California requires a written contract for any home improvement job over $500, and the contract and any changes to it have to be in writing and tell you about your rights to cancel. It should also say who gets the permits and give a date of completion. Give yourself time to read it before work starts, and ask me about any line that isn't clear.
How much can a contractor ask as a down payment on a sunroom in California?
In California the down payment can't be more than $1,000 or 10 percent of the contract price, whichever is less. There's no exception for special-order materials, so that limit holds even when windows or panels are made to order.
What is the best way to plan a sunroom addition on an existing patio?
Start with how you'll use the room, because that choice sets the room type, the roof and whether it's heated and cooled. Then look at what the room would sit on, since an existing slab, deck or cover may carry it as is or may need work first. I go through both with you on the visit, so you know what you're choosing between.
Rooms built for how you'll use them
Four season sunrooms
Pick this if you want a room you'll sit in through winter evenings and hot afternoons, with all-weather windows and heating and cooling built in.
Three season sunrooms
A good fit when you mostly want shade and a spot out of the wind and bugs, without paying for a fully heated and cooled room.
Book a visit to measure your sunroom
Have the room size in mind, whether you want it heated and cooled, and any HOA approval you already hold, so we can cover more in one visit.
