Backyards and patios across Santa Ana
Santa Ana is one of the bigger, more built-up cities we work in, and a lot of the houses we're called to are single-family homes where the backyard is the only room left to grow into. The calls sound a lot like the ones we get at home in Placentia, next door in Orange and Garden Grove, and as far out as Norwalk, from homeowners who want more use out of a patio and a room they'll actually sit in.
What's already out back usually shapes the job more than anything. Many yards here have an older concrete slab, a patio cover added years ago or both, and I check whether that slab can carry walls, glass and a roof before we draw anything, because some of it you can't know until the old concrete is opened up.
Our services in Santa Ana, CA
Plenty of Santa Ana patios sit in full afternoon sun with nothing over them, so a cover is often the first step to using the space. We set the posts on proper footings and tie the cover into the house so rain runs away from your wall instead of into it.
When a patio is already covered, adding walls and windows is usually the most direct way to a usable room. We check the old posts, beams and slab first, because an enclosure puts weight and wind on parts that were only built to hold up a roof.
Turning an older patio into a full sunroom works when the slab underneath can take it. We look at its thickness and cracking before we plan, and if it can't carry the room we'll tell you and lay out new footings instead of building on a guess.
Some Santa Ana homes already have an older sunroom or enclosed patio that leaks at the roof line or gets too hot to sit in by midday. Our sunroom remodeling starts at the joint with the house and the glass, since that's usually where the trouble is, then works out from there.
With the yard as the only space left to add on, a lot of homeowners here want a room they can use every month as a den or an office. A four season sunroom with insulated walls and glass is built for that, so we plan it like the addition it is, with footings, a solid tie-in to the house and the electrical it needs.
If you mostly use the yard in the evenings, a screen room keeps the bugs off dinner without the cost of glass and insulation. It's lighter on the slab, though we still check what it sits on and how its roof meets the house.

How it works when you call us about a Santa Ana sunroom
Call or send the form
Call (657) 226-2045 or use the form, and we'll get back to you to set up a time to come out. Pick a time you can be home, since I'll want to walk the yard with you.
I look at your patio
I come out myself, look at the slab, cover or deck that's already there and where the room would join the house, and ask how you plan to use it. You get the plan and the estimate in writing, so you know what the price covers before you decide anything.
We permit and build it
We pull the Santa Ana permit and handle the paperwork, including drawings from a licensed architect or engineer when the city asks for them, and the city's review is usually what sets the start date. Then our own crew builds the room, and we meet the inspector on site.
Walk through the finished room
When the room is done and inspected, we walk through it with you and check the doors, the windows and the joint with the house. It's the last step before we call the job finished, and satisfaction guaranteed on every job is the promise we work to.
Santa Ana sunroom questions
Do I need a permit to add a sunroom in Santa Ana?
Yes. Santa Ana requires a permit to build, alter or repair a building and to add or change electrical, gas, mechanical or plumbing work, and a room attached to your house is building work. The city's Building Safety Division issues the permit, reviews the plans and inspects the work, and most applications need Planning Division approval before they go to the building side, so that two-step path is the part of the schedule we plan around.
Can a patio cover permit be issued the same day in Santa Ana?
It can. The city lists patio covers, along with simple jobs like water heater change outs and minor reroofs, among the permits that can be issued over the counter the same day. Other projects may need plans submitted for review, and an enclosed sunroom is more involved than a cover, so I'll tell you at the estimate which path yours is likely to take.
How long does a building permit stay valid in Santa Ana?
A Santa Ana permit becomes invalid if work doesn't start within 180 days after it's issued. It also lapses if work is suspended or abandoned for 180 days once it's started, so it's worth having the room's design settled before the permit is pulled.
Is a shed, fence or retaining wall exempt from a permit in Santa Ana?
Some are. The city exempts one-story detached sheds, playhouses and similar structures up to 120 square feet, fences up to 7 feet high, and retaining walls up to 4 feet measured from the bottom of the footing to the top, unless the wall carries added load or holds back flammable or combustible liquids. A front-yard fence still needs a permit from the Planning Division, and a city handout from 2022 says fences and walls go through Planning review, so check before you count on the exemption, and keep in mind none of it covers a room attached to your house.
Does a contractor need a Santa Ana business license?
Yes. The city requires a business license and an annual business license tax for every business operating within city limits, and its permit rules say a contractor must hold a current Santa Ana business license. It's a fair thing to ask any contractor about before you sign, along with whether they're licensed and insured, which we are.
How do I find out what a sunroom will cost in Santa Ana?
The way to get your own figure is to have me look at the spot, because the price turns on things I can only judge in person. The big ones are the kind of room, since a screen room or three season room costs less than a four season room with insulated glass, plus its size, whether your existing slab or cover can be reused or needs new footings, any electrical, and whether the city asks for architect or engineer drawings. Choosing a lighter room or keeping a slab that's still sound are the usual ways to bring the number down.
