Sunroom construction in Los Angeles CA - a room built for how you'll use it
Got a patio you rarely use because of sun, bugs or evening chill? We build a sunroom that fits how your family will use it.

What does it take to build a sunroom onto a Los Angeles house?
Sunroom construction in Los Angeles means adding a new room onto your house. It can be an open or screened room, or an enclosed room that's heated or cooled and opens into the house. The first thing we settle with you is which kind you want, because that choice decides how the rest of the room gets built.
Most people who call us have a patio or deck they hardly use, or a back of the house that gets too much sun to sit out in, and they want a room the family will actually spend time in. The price mostly comes down to the room type, its size, how much glass it has and what it sits on, since a slab or deck that needs work gets fixed before the room goes up. The schedule usually turns on the permits your address needs and how much prep the base takes, and I'll give you a written quote for your room once I've seen it. We find out which office covers your address and handle the permit applications and inspections when your project needs them, and your contract says in writing who's getting the permits.
What happens after you call about a sunroom in Los Angeles?
Call or send a message
Call (213) 340-1547 or use the form, and we'll get back to you to set up a time for me to come out. We answer seven days a week, 8 AM to 9 PM, so evenings and weekends work too.
I visit and measure
I look at the patio, slab or deck, measure, and ask how your family plans to use the room. Then I send a written quote, so you see the work and the price before you agree to anything.
Permits, then the build
Once you sign, we sort out the permits that apply to your address. Then our own crew builds the room, with a lead installer running the site.
Walk through the room
When the room's done, I come back and walk through it with you, checking the doors, tracks and glass together. Our work is satisfaction guaranteed.
How we handle sunroom construction
Before anything gets built, I settle two things with you, the kind of room you want and where it sits on your lot. The spot matters because local code sets limits on floor height above the ground, setbacks, easements and stormwater, and Los Angeles zoning treats an addition to your house as new construction, so a sunroom gets planned like any other new building work. Next we look hard at the base, and a tired slab or weak deck gets fixed first instead of covered up. We also keep your escape routes working, since every sunroom type has to meet the local code's rules on exits and emergency escape openings, and a bedroom window or back door your family would use to get out can't end up trapped behind the new room. Then our crew frames the room and sets the glass, doors and tracks, the part I watch closest after years of installing windows and sliding doors, because a frame that's a hair out of square shows up later as a slider that drags or a seal that leaks. California's Energy Code sets efficiency rules for additions, so on an enclosed room we pick the glass and seals with those rules in mind, and when the room's done we clean up and get it ready for the walk-through.
If you already have an older room that sticks, leaks or never got used the way you hoped, our sunroom remodeling work may make more sense than building new. If shade and fewer bugs are all you're after, screen room installation gives you a lighter build. We're based in Los Angeles and work across the city and the cities around it, including Pasadena, Glendale, Burbank and Alhambra.

Questions about building a sunroom in Los Angeles
How much does a sunroom addition cost in Los Angeles?
A sunroom addition in Los Angeles usually costs about $23,000 to $66,000 per job, and that's the going range around here, not a quote from us. Where yours falls depends mostly on whether it's screened or enclosed, how big it is, the glass and how much work the slab or deck needs. I'll come out, look at all of that and send you a written quote.
What is the best way to choose between a screened room and an enclosed sunroom?
Start with how you'll use it, because one national sunroom specification treats a screened or open room as unheated outdoor space and an enclosed room that's heated or cooled and opens to the house as living space. The enclosed room's windows and doors have to meet rules on air leaks, water leaks and holding heat, a lot like a good replacement window, so it's a bigger build. Your local code has the final say on what counts as outdoor space, and I'll ask plenty of questions about how your family will use the room before you pick.
How much can a contractor ask for up front on a sunroom in California?
In California, the down payment on a home improvement job can be no more than $1,000 or 10 percent of the contract price, whichever is less. That limit holds even when parts of the sunroom are made to order, since the rule has no exception for special-order materials.
How do I check the zoning rules for my lot in Los Angeles?
Look your address up in ZIMAS, the city's Zone Information and Map Access System, which Los Angeles City Planning points owners to for official guidance. The city's zoning summary leaves out some rules that apply to a specific property, so the summary alone won't tell you everything about your lot. We settle where the room can sit before anything else gets planned.
Does a sunroom contractor need a license in California?
Yes, California contractors are licensed by the Contractors State License Board, and contracting without a license on jobs that total $500 or more is a criminal misdemeanor. We're licensed and insured, and you're welcome to ask about our license before you sign anything.
What should a sunroom contract include in California?
California requires a written contract for any home improvement project over $500, and it has to give a date of completion. Ask to see that date before you sign, along with the line that says who's getting the permits.
