Patios and backyards across Irvine
Irvine was planned from the start, and you can see it from the street. Most neighborhoods were laid out as villages of tract homes, many with an HOA, with stucco walls, tile roofs and a concrete patio out back off the family room. The newer neighborhoods tend to have smaller yards and houses set close together, while the older ones have patios and first-generation sunrooms that have seen decades of use. The city has also worked to keep open space alongside the building, so homes in places like Quail Hill and Shady Canyon often back onto hills and trails. The calls we get here differ from the ones in Westminster, because in Irvine the work is usually about fitting a room to a smaller yard and to what the neighborhood allows.
That shapes the job in two ways. The room has to suit a house that matches its neighbors, so we match the stucco, trim and roof lines, and it usually sits on a slab that was poured for a table and chairs, not walls, so I check that slab before anything else.
Working in Irvine: permits, licenses and what moves the price
In Irvine, the permit is the city's call. The City of Irvine's Community Development Department issues permits for most construction the code regulates, and a room built onto your house is that kind of work, so the schedule has to allow for the city to review plans before we build. Before you hire anyone, please ask for two things, the contractor's state license, which comes from the Contractors State License Board, and their Irvine business license, since the city requires every business working here to hold one. We're fully licensed and insured, and when a project needs a permit we prepare the plans, file them with the city and meet the inspector, and we tell you early what we need from you, such as your HOA's approval.
What moves the price is mostly the room itself. Its size, glass or screens, insulated walls and roof for year-round use, how it ties into your house roof and whether the slab needs work before it can carry walls all count. The schedule turns less on the build than on approvals, your HOA first if your neighborhood has one and then the city's plan review. My written estimate spells out what's included so you can compare it fairly, and we do the same work for homeowners in Costa Mesa and Newport Beach.

Patio-to-sunroom conversion
Many Irvine homes already have a concrete patio off the family room, and it's the natural place for a sunroom. I check that slab for cracks and thickness before we plan walls on it, because a room is only as sound as what it stands on.
Three season sunrooms
If you want a bright room for most of the year without paying for insulated walls, a three season sunroom is usually the honest fit. We build it with panels you can open, so the patio feels like part of the house without more room than you'll use.
Patio cover installation
Smaller Irvine yards often have space for a cover but not a full room, and a good cover still turns a bare slab into a patio you'll sit on. We size the posts and footings to the cover and match it to the house so it sits well with your neighbors and your HOA.
Sunroom remodeling
In the older neighborhoods we find sunrooms added years ago that now leak where they meet the house or sit unused behind tired panels. We fix what's underneath first, then reseal the roof tie-in and replace the panels so the room earns its place again.
Screen room installation
For homeowners who want to sit out back in the evening with the bugs kept out, a screen room is the lighter build. It goes up on your existing patio or deck with screen panels instead of glass, which keeps the room simple and the cost down.
Four season sunrooms
Families who need a real extra room for a desk or a guest usually want a four season room with insulated walls and roof. We tie it into your house roof and match the stucco and trim, since most Irvine neighborhoods expect an addition to look like it came with the house.
What happens after you call us about an Irvine sunroom
Call or send a message
Call (657) 329-2023 or use the form, and we'll set a time for me to come out to your house. Our phone hours run into the evening every day, so you needn't call from work.
I measure and check underneath
I measure, look at the slab, deck or cover the room will stand on and ask how you plan to use it, because that decides what kind of room makes sense. Then I send you a written estimate in plain words that spells out what's included.
We handle permits and paperwork
If you go ahead and the project needs a permit, we prepare the plans, file them with the city and meet the inspector, and new online applications in Irvine now go through the city's PermitsDIRECT! system. We'll tell you early if we need anything from you, such as your HOA's approval.
We build and walk through
I'm on site with our crew through the build until the room is finished. You needn't be home every day, but please plan to be there when we walk through it together at the end.
Common questions
Do I need a permit to build a sunroom or patio cover in Irvine?
A patio cover in Irvine needs a permit no matter its size, and most other construction the code regulates needs one too. Even work on the city's exempt list still needs its own electrical, plumbing or mechanical permits unless it's exempted as well, which matters if your new room gets lights, outlets or a ceiling fan. If you'd like to ask the city yourself, the permit line is (949) 724-6313, and the city's permit guide lists the exceptions.
How do I check that a sunroom contractor is licensed in California?
Ask the contractor for their state license, because California requires one whenever a job needs a building permit, uses employees or totals $1,000 or more in labor and materials, and nearly any sunroom meets at least one of those. The state also limits the down payment on a home improvement job to $1,000 or 10 percent of the contract price, whichever is less, so be wary of anyone asking for more up front. We're fully licensed and insured, and I'm glad to show you our license at the estimate.
How much does a sunroom cost in Irvine?
There's no single price, because a screen room on a sound slab and an insulated four season room tied into your roof are very different jobs. Glass instead of screens, insulated walls and roof, electrical work, matching stucco and trim, and any repair the slab needs all add to the cost, while building on a sound existing patio and keeping the room to the size you'll use keep it down. Plans and permit work are usually part of the job here, so my written estimate spells those out along with everything else.
What roofing material does a sunroom need in Irvine?
All new roofs in Irvine need Class A roofing material, the highest fire rating, and that includes the roof over a new room. When less than half of an existing roof covering is replaced within a year, Class A is still the rule, though the replacement may be Class B if the roofing that stays is Class B or lower. We work this out when we plan how your room ties into the house roof, so the materials are right before the inspector sees them.
Will adding a sunroom in Irvine mean I have to add fire sprinklers?
Usually not. The city requires sprinklers in an existing house only when additions and alterations within any two-year period exceed half its gross floor area, and the rule covers buildings larger than 5,500 square feet. If your house is that large and you're planning other work too, please tell me at the estimate so we can plan the room with that in mind.
How long does it take to get a sunroom approved and built in Irvine?
Most of the wait is usually in approvals, not the build, with HOA review first if your neighborhood has one, then the city's plan review, then ordering the panels. Once the city issues a permit for work on a house, it stays valid for 18 months unless the building official extends it in writing, so you have room to schedule. I'll give you a realistic schedule for your room when I come out.
