Sunroom contractor in Costa Mesa, CA - rooms planned around the patio you have
Clearview North Tustin Sunrooms & Patios builds sunrooms, patio enclosures and patio covers for Costa Mesa homes, and remodels rooms that no longer suit how you use them. I measure and plan each room, and our own crew builds it.

Costa Mesa homes and the rooms we add to them
Costa Mesa is a short drive from our base in North Tustin. Most of the houses we see there are single-story, with a concrete patio or an aging patio cover off the family room. Backyards tend to be compact, so a sunroom usually has to fit the patio footprint that's already there instead of reaching further into the yard. The calls are a lot like the ones we get in Anaheim, where many people want an older patio turned into a room they'll actually use.
That's why the slab and the house wall the room ties into decide more of the job than the glass does. Before I draw anything, I want to know whether the slab is sound, which way it slopes and what the roofline will let us attach to.
Services in Costa Mesa, CA
Patio-to-sunroom conversion
Many Costa Mesa backyards already have a concrete patio right off the house, and that makes it the natural place for a room. We check the slab's condition and slope before we plan walls on it, because a room is only as square as what it sits on.
Sunroom remodeling
Older sunrooms and enclosed patios here often have single-pane glass, worn seals or a roof that leaks where it meets the house. Our sunroom remodeling work replaces the parts that have failed and keeps the frame when it's still sound, so you aren't paying for a new room you don't need.
Patio cover installation
Some homeowners only want shade over the patio, and a cover without walls is the simpler and less costly choice. If you think you'll want walls someday, we can plan the posts and beam with that in mind.
Screen room installation
If you mostly want to sit outside in the evening without bugs, a screen room on the existing patio does that without glass. It's the room I point people toward when they don't plan to heat or cool the space.
Four season sunrooms
When the room will be used year-round with heating and cooling, it needs insulated walls, roof panels and glass. We spell out each of those in writing so the room you agreed to is the room that gets built.
Sunroom design
On compact lots there's little room for error on size, on what the neighbors see and on where the roof meets the house. I lay the room out on paper with you first, because changing a drawing costs nothing and changing a built wall costs a lot.
Working in Costa Mesa: permits, licenses and what moves the price
In Costa Mesa, building permits come from the city's Building Safety Division. Your start date depends on how the city's review goes as much as on our crew, so we get the drawings complete before anything is submitted. Before you hire anyone, check that they hold a license from the California Contractors State License Board, the state board that licenses anyone who builds or alters structures here. We're licensed and fully insured.
For the work we do, we look up which office reviews your address and handle the permit applications and inspections. We do the same in Santa Ana and Irvine. The price moves with the type of room, the windows and roof panels, whether the slab needs repair or a new base, and how the roof ties into the house. The schedule turns on the permit review, how long the materials take to arrive and what we find in the slab. Your written estimate lists the room type, windows, roof and base, so you can see each piece before you decide.
What Costa Mesa houses and yards mean for a sunroom
A lot of the patios here were poured decades ago, and the covers over them have been patched more than once. An older slab can be cracked, settled or sloped toward the house. A room built on top of that shows it later in doors that stick and glass that doesn't sit right. I look at the slab first and tell you plainly whether we can build on it as is, whether it needs work, or whether a new base is the better choice.
Yards are small and neighbors are close, so the side of the room that gets afternoon sun matters. A wall of glass facing that sun heats a room fast. Sometimes I'll suggest an insulated roof over a glass one. It gives up some light, but the room stays usable on hot afternoons.

Call or send a message
Call (657) 356-0209 or use the form, and we'll set a time to come out. It helps to have a rough idea of how you want to use the room.
Measure and check the slab
I come out myself, measure the space and look at the slab, deck or wall the room will tie into. I'll also ask how you plan to use the room, because that decides between screens, glass and insulated walls.
Review your written estimate
You get a written estimate that spells out each piece, from the room type to the windows, roof and base. Compare it with what we talked about, and ask me to change anything that doesn't match.
We handle the permit steps
Once you're ready, we take care of the applications and inspections for our work. The city's review sets when our crew can start.
Build and final walkthrough
Our own crew builds the room, led by an experienced installer, and I check in as the job goes. When it's finished, I walk through the room with you before we call it done.
Costa Mesa sunroom questions
Do I need a licensed contractor to build a sunroom in Costa Mesa?
Almost certainly. The state licensing board requires a license when a project needs a building permit, uses employee labor, or has contracts totaling $1,000 or more in labor and materials. Nearly any sunroom passes that dollar mark, and the board doesn't allow a larger job to be split into smaller contracts to stay under it.
How do I apply for a building permit in Costa Mesa?
You apply online through TESSA, the city's permit system, where you enter all the application information and upload the plans. The city ignores paper forms and returns incomplete applications, so one missing detail sends it back. You can read what's required on the city's building permits page, and we prepare and submit the applications for the work we do.
Which projects can get an Insta-Permit in Costa Mesa?
Insta-Permits are for simple jobs with a limited scope. The city's list covers residential HVAC, re-pipe, water heater, EV charger, panel upgrade and re-roof work. A sunroom isn't on that list, so ask the Building Safety Division how your room will be reviewed, or we can look it up for your address.
What are the penalties for unlicensed contracting in California?
A first offense is usually a misdemeanor, with up to six months in jail, a $500 fine or both, and an administrative fine of $200 to $15,000 can be added. Those penalties fall on whoever contracts without a license. They're still a good reason to check a contractor's license with the state board before you sign anything.
How much does a sunroom cost in Costa Mesa?
It depends on the type of room, the glass and roof panels, and the condition of the slab or deck under it, so I give you a figure only after I've measured. A screen room on a sound slab costs far less than an insulated four season room that needs a new base, and electrical, heating and cooling add to the total. The written estimate lists each piece, so you can see what you'd save by keeping the room simpler.
How long does it take to build a sunroom in Costa Mesa?
The city's permit review and the wait for windows and roof panels usually take longer than the build itself. A slab that needs repair or a new base adds a step before framing starts. Once I've seen your site, I can tell you which of those apply to your room.
