Request an estimateWhat is a four season sunroom, and does it fit your house?
A four season sunroom in Palmdale is a glassed-in room built into your home's existing construction, with insulation, electricity and heating and cooling, so it stays temperature-controlled and opens to the rest of the house like any other room.
Most people who call us want more use out of the back of the house and aren't sure where to start, so it helps to know what drives the job. The price moves mostly with the room's size, the materials you choose and the foundation, since pouring a new slab or shoring up a deck costs more than building on a sound base that's ready to go. The schedule turns on things around the build itself, like the permit, how quickly your choices get settled and whether an existing deck needs a closer look first, and the written estimate I send after measuring puts your own numbers on all of it.
How we build a four season sunroom
The first thing I settle with you, before any design, is whether your back door and windows stay where they are or come out to open the room into the house. That choice matters because a sunroom with its own heating and cooling and the house doors and windows still in place stays thermally separate from the home and has its own requirements, while a room without that separation is basically a regular room addition. Once that's decided, we look at what the room will sit on and plan the insulation, wiring and heating as part of the room from the first drawing, not as add-ons later, because that's what makes it feel like the rest of the house. Then our crew sets the base, frames the walls and roof where they meet your house, closes it in and finishes it out.
Some people come in asking for a four season room and realize they want something lighter. A three season sunroom is enclosed with glass but has no insulation or heating and cooling, and if you only want to close in the space you already have, patio enclosures are often the simpler job. If you know you'll want to use the room every month, I'd steer you to the four season build now, because adding insulation and heat later means redoing a good part of the room.
Getting a four season sunroom approved in Palmdale
The first step with any permit here is finding out which office it goes to, because some homes with a Palmdale mailing address sit in unincorporated LA County, outside the city's jurisdiction. We check whether your address falls under the City of Palmdale, LA County or Kern County, and when your room needs a permit, which a room tied into the house's wiring and heating usually does, we file with that office and set up the inspections. Inside city limits, that office is Palmdale Building and Safety, which oversees building on new, remodeled and existing homes.
Around Palmdale we see plenty of back yards with an older slab or a wood deck already in place, and rooflines that take some thought to tie into. We run into the same on jobs in Lancaster and Quartz Hill, and we handle them the same way, starting with what's underneath and how the roof meets the house before we draw anything. We're based in Palmdale and work in cities around the Antelope Valley, so if you're not sure we come out your way, just ask.
Why call us for a four season room
The owner measures every job
I come out myself to look at the job, measure and talk it through with you, and I'm on site checking the work while our crew builds. The person who walked your yard is the one making sure the room goes up the way we planned it.
In business since 2017
We've been building sunrooms, patio rooms and patio covers out of Palmdale for nine years, and we're known for the jobs with a catch, like an old deck, a cracked slab or a room someone wants changed. If your house has a quirk, we'd rather work it out with you than talk you around it.
Licensed in California, insured for every job
We're fully licensed and insured, so the work on your house and the people doing it are covered. California's contractor license classes include general building and residential remodeling contractors, and we're glad to walk you through how that applies to your room.

Frequently asked questions
How much does a four season sunroom cost in Palmdale?
A national price guide puts adding a four season sunroom at about $20,000 to $80,000 per project across the US, so treat that as a broad range, not a Palmdale quote. As I mentioned up top, size, materials and the foundation move it most, and the written estimate I send after measuring gives you your own number.
Can a four season sunroom be built on an existing deck?
Often it can, but a deck typically needs added beams, posts or footings first to carry the weight and loads of a full room. The sunroom industry's trade group advises asking a local structural engineer whether your deck is suitable, so plan that review before the build, and I'll tell you what I see when I come out.
What is the best way to heat a four season sunroom in California?
Plan on a heat pump for any new heat, because California Energy Commission guidance says new or replacement space heating serving an addition has to be one. Turning an unheated space into a heated and cooled room counts as an addition, so a four season room may well fall under it, which is one more reason we plan the heat with the rest of the room.
How do I apply for a sunroom permit in Palmdale?
Inside city limits, permit applications go through the city's online permit portal, and every one has to include a construction waste management plan. Fees are based on the project's estimated value, which weighs the type of construction, the square footage and any covered patio or utility space. We file it for you, and if you have questions about the process yourself, Building and Safety takes them at 661-267-5353.
Can I turn my three season sunroom into a four season room?
Usually, but it's a real project, since a conversion can mean new windows, insulation, extending your heating and cooling and pouring a concrete foundation. I'd start by checking what the room sits on and how it's tied to the house, because that tells us whether the upgrade makes sense or a new build does.
What energy rules does a new sunroom have to meet in California?
California's newest Building Energy Efficiency Standards are now in effect, so it's fair to ask any builder how their design meets them. We'll go over how your room's insulation, glass and heat line up with them before you sign.
Other rooms we build off the back of the house
Three season sunrooms
A good fit if you want a bright, enclosed room for part of the year and don't need it heated and cooled like the house.
Patio enclosures
When you'd like to close in the patio you already have and keep the job simple, an enclosure gives you more usable space right off the back door.
