What does a sunroom addition in Hacienda Heights involve?
A sunroom addition is a room with enclosed walls built onto your house, and it can be designed to be heated or cooled. We build sunroom additions in Hacienda Heights, CA, so a patio or a bare back wall becomes a bright room you'll use.
Most calls start with a patio that's too hot by afternoon or a house that's one room short. The price moves with the size, whether the room is closed off or open to the house, the glass, and what's out back right now, and the schedule turns mostly on settling the design and getting the county permit through. If you already have a slab or deck back there, patio-to-sunroom conversion is worth a look too. Your own figure comes in the written estimate after I've seen the spot, because I'd rather you know what you're getting into before you sign anything.
How do you know it's time to add a sunroom?
A patio nobody sits on
You've got the space out back, but by afternoon it's too hot, too bright or too windy to use. That usually means it works a few hours a day and sits empty the rest, and every summer you wait is another one spent indoors looking at it.
A house one room short
The family room is doing three jobs and homework lives on the dining table. An addition gives you that extra room without moving, and waiting usually just means another year of shuffling furniture.
Afternoon glare out back
You close the blinds at three every day and the back of the house still warms up. That's usually down to which way that wall faces, and it's worth knowing before you put more glass on it, because a sunroom on the wrong wall makes the problem bigger.
How we build a sunroom addition
I start with how you want to use the room, then look at the walls it could go on. Which wall a room goes on changes how bright and warm it gets, so we pick the spot and the glass together before we settle on a size. High-performance glass generally lets in more light and less heat than a typical window, and that choice decides whether your daylight comes with a bigger summer cooling bill. Once the room is set on paper, my crew and I build it and clean up behind ourselves. The sun doesn't negotiate, so we plan around it.
Most additions end up as one of two rooms. If you want heating and cooling and plan to sit in it all year, look at our four season sunrooms. If it's mostly for mild months and evenings, three season sunrooms keep the build simpler.
Closed off from the house
In one published building code, a sunroom closed off from the house with its own heating or cooling counts as nonliving space. It suits you if the room is a getaway off the patio and you're fine keeping a door between it and the house.
Open to the house
In that same code, a sunroom open to the house is heated or cooled and counts as living space. If you want the room to work as part of the home, pick this type from the start so the plan is built around it.

If your house is in unincorporated LA County, LA County Public Works issues the permit, and it requires one for additions like adding a room. Which county office serves a given address isn't always obvious, so the county tells owners to contact the local office listed in its Service Locator to ask what a project needs, and part of that can be a plan check, where reviewers go over the plans against safety, building and environmental standards. LA County Planning separately handles land use permits for areas outside a city, looking at zoning, allowed uses and design, plus things like plants, hillsides and community character. We look up which office handles your address, and when the job needs a permit, we take care of the paperwork and work through the inspections with you.
Around here we see a lot of backyards with an existing patio and strong afternoon sun, so the wall and the glass get more of our attention than people expect. We're based in Hacienda Heights and run into the same kinds of houses on jobs in Whittier and La Puente. If your city isn't listed, call and ask.

Frequently asked questions
How much does a sunroom addition cost in the Los Angeles area?
Sunroom additions in the Los Angeles area usually cost about $23,000 to $66,000 for a 200-square-foot room. That's the area's going range, not our price, and where a job lands in it mostly comes down to the room type, the glass and what's out back now. Your own number comes in the written estimate after I've measured.
Do I need a permit for a sunroom addition in Hacienda Heights?
If your property is in unincorporated LA County, yes, because the county requires a permit for adding a room. Not sure which office covers your address? The county's Service Locator lists it, and we look it up on every job anyway.
How do I keep a sunroom addition from getting too hot?
Start with the wall it goes on, since south-facing windows let in the most winter sun and less direct summer sun, while east- and west-facing windows bring in extra heat and glare. If west is the only wall you've got, the glass choice has to carry more of the load.
How much can a contractor ask up front for a sunroom in California?
In California, a down payment before work starts can be no more than $1,000 or 10 percent of the contract price, whichever is less. A small number of contractors with blanket performance and payment bonds are the exception, and special order materials don't change that limit.
Do I need a written contract for a sunroom addition in California?
Yes. California requires a contract for any home improvement project over $500 in combined material and labor, and it has to include specific information on your rights and responsibilities as a consumer. A sunroom addition clears that bar with room to spare.
How long does a sunroom addition take from first call to finished room?
There's no fair number until the design is set, because the schedule turns mostly on settling the room type, wall and glass, and on the county's review of the plans. The build itself is usually the shorter stretch. I'll give you a straight read on both once I've seen the spot.
