Request an estimateSanta Ana: older houses, patios worth enclosing
Santa Ana is a big, busy city with a lot of older homes in it. Many of our calls there come from people with a backyard slab, a covered patio or a room someone added years ago that never quite worked. Plenty of these houses are single story with the yard right off the kitchen or family room, and that's about the best setup there is for a sunroom, because the new room can open straight off the space you already live in.
Before we talk about glass or insulation, I want to know what the room will sit on, because a slab poured for a table and chairs wasn't necessarily poured to carry walls and a roof. Some are fine as they are and some need new footings along the edges, and we only know which once we look closely. We see a lot of the same backyards next door in Garden Grove.
Working in Santa Ana: permits, plans and what sets the price
Sunroom work in Santa Ana goes through the city's Building Safety Division, which issues building permits, reviews the plans and inspects the work. Most applications need Planning Division approval before they reach the building side, so that review usually sets when we can start. Any contractor working in the city has to carry a current City of Santa Ana business license, and that's a fair thing to ask about before you hire anyone, us included.
If your room needs a permit, we take care of it. We prepare the plans, file them with the city, book the inspections and let you know ahead of any visit where you need to be home. The price turns mostly on the kind of room, from a screen room up to a fully insulated four season room, and then on the glass, the size, how the roof ties into your house and what the slab or deck underneath needs. The estimate puts all of that in writing for your job. We work the same way in Orange and in many of the cities around La Palma, on both the Orange County and Los Angeles County sides.

Patio-to-sunroom conversion
Plenty of Santa Ana backyards already have a slab and a cover off the back door, and that makes a natural start for a sunroom. We check whether that slab can carry walls and a roof, and we add footings where it can't before any framing goes up.
All season rooms
If you want to sit in the room on summer afternoons and winter evenings alike, an all season room with insulated walls, roof and glass is usually the right pick. We settle the insulation and glass with you before we build, because those are the hardest choices to change later.
Patio cover installation
A lot of the older patio covers we see in Santa Ana are tired wood or thin aluminum that's started to sag. We replace them with a cover sized and fastened properly to your house, and we can build it so walls can go in later if you want a room someday.
Sunroom remodeling
Rooms added decades ago often leak where they meet the house, or run too hot or too cold to sit in. We start with the base, keep what's sound and rebuild the rest so the room gets used again.
Screen room installation
If you mainly want the yard without the bugs, a screen room on your existing patio is the simplest room we build. It keeps the air moving, and it's the lower-cost choice when you don't need a room you can heat or cool.
Sunroom additions
On a lot with room to spare and no patio to build from, a sunroom addition starts from the ground with its own foundation. We plan where it meets the house so the roofline and the doorway look like they were always there.

Frequently asked questions
Do I need a permit to build a sunroom in Santa Ana?
Plan on needing one, because the city requires a permit to build onto or alter a building and to add or change wiring, and only finish work like painting, tile, carpet and cabinets is exempt. The city's permits and inspections FAQ lays out the rules, and if your room needs a permit, we handle it as part of the job.
How long does it take to get a patio cover permit in Santa Ana?
A patio cover can sometimes be permitted the same day, because the city lists patio covers among the simpler permits it can issue over the counter. A sunroom with walls, glass and wiring is more likely to need plans submitted for review first, and that review is the part of the schedule nobody can rush.
Is a small sunroom exempt from permits like a shed in Santa Ana?
No, the city's exemption covers one-story detached sheds, playhouses and similar structures with up to 120 square feet of floor area, and a room attached to your house is an alteration to the building. If you're thinking about a freestanding room instead, ask the Building Safety Division before you count on the exemption.
How long does a building permit stay valid in Santa Ana?
A Santa Ana permit lapses if work doesn't start within 180 days of the permit being issued, or if the work stops for 180 days after it starts. We plan the start date around the permit so it doesn't sit.
How much does a sunroom cost in Santa Ana?
The price comes down mostly to the type of room, with a screen room at the low end and an insulated four season room at the high end. After that, the size, the glass, how the roof ties into your house and whether the slab needs new footings move the number. The free on-site estimate gives you the figure for your own room.
What causes an old sunroom to leak or crack?
Most of the time it's the base or the seam where the room's roof meets the house. A slab that settles pulls the frame out of square, and a roof tie-in that never got proper flashing, the metal strips that shed water at that seam, lets water in. In older Santa Ana additions we check both first, and the fix depends on what we find once it's open.
