Sunroom additions in Whittier CA - a bright room you can use more of the year
Patio sitting empty half the year? We add a sunroom that's level, tight to your house and built for how you'll actually use it.
What does a sunroom addition in Whittier involve?
A sunroom addition in Whittier is a new room with enclosed walls built onto your house, usually over the patio, slab or deck you already have, so you get a bright space you can sit in through more of the year.
Most people who call us have a patio or deck they only use when the weather's just right, and they want to know what kind of room fits and what it'll take. The price mostly moves with the size of the room, whether it needs a new foundation, and whether you want it heated and cooled with insulated glass or left closer to a screened porch. The schedule mostly turns on the permit, because the city or the county reviews the plans before we build, so we check early which one handles your address. I put the estimate in writing so you can look over your own figures at home.

What sunroom additions can look like
How we build a sunroom addition
First I ask how you'll actually use the room. Is it morning coffee in spring, or a place to sit in August with the air on? That answer picks between a screened, three season or four season room, so we settle it before anything else. Then we look hard at the base, whether it's a slab, a patio or a deck, and at the wall the room will join, because those are the parts nobody sees and they're where a sunroom is won or lost. We frame it level and square, and the insulation goes in while the walls are open, since putting it in afterward is harder and runs more. Our own crew builds it from the base through cleanup.
If you want a room you can heat and cool like the rest of the house, that's one of our four season sunrooms. If you'd rather keep it simpler and use it in the milder months, three season sunrooms still get you out of the wind and dust without the heating and cooling.

Every choice explained before signing
I come out myself to look, measure and talk through each option with you before you commit to anything. When you understand what you're buying, you end up with a room you'll actually use.
Licensed, insured and our crew
We're licensed and insured. We've been in business since 2021, and our own small crew does the building with me on site leading it, so the person who walked your patio is the one answering for the work.
We check your address first
We're based in Whittier and work in the cities around it, both city addresses and unincorporated county areas, so the first thing we look up is which office handles yours. The city says the state's updated wildfire hazard map may affect building codes and insurance going forward, which is one more reason that check comes early.
Getting the room type right comes before anything else, so tell us how you'd like to use the space and I'll come out and walk it with you.

What happens after you call about a sunroom addition?
Call or send the form
Reach us at (562) 203-1022 or through the form, and we'll get back to you to set up a visit. Have your address handy, because it tells us whether the city or the county handles the permit.
I come out and measure
I look at your patio, slab or deck and the wall the room will join, then walk you through the room types and what each one means for how you'll use it. You get the estimate in writing, so you can weigh the price at home with nobody waiting on an answer.
We handle the permit side
Inside Whittier, the city's planning staff look at the project first, and then Building & Safety reviews the plans, so planning time comes before any building time. We take care of that paperwork, or the county's if your address sits outside city limits, and keep you posted on where it stands.
Our crew builds the room
Our own crew builds it from start to finish with me on site, and we meet the inspector for each of the several inspections a Whittier job usually needs. The city stamps the plans and issues a Job Card with the permit, so keep both out of the sun and weather and ready for each inspection.
Sunroom addition questions from Whittier
How much does a sunroom addition cost in Whittier?
Across Los Angeles, a sunroom usually costs about $16,000 to $120,000 per project, according to a cost guide for the area. Larger rooms that need a foundation and come with heating and air conditioning land at the high end. That's the market's range, not our price, and my written estimate gives you the figure for your room.
What is the best way to choose between a three season and four season sunroom?
Pick by how you'll use it, because a four season room is fully enclosed, heated and cooled, while a three season room has no heating or cooling and uses uninsulated windows or screens. So the real question is whether you want a room you can sit in during any weather or one that stays closer to a screened porch.
How do I know who issues the permit for a sunroom at my Whittier address?
If you're inside city limits, the City of Whittier issues it, and if your property is in unincorporated LA County, LA County Public Works does through its South Whittier district office in Norwalk. We check your address early so we know which one it is, then take care of the permit paperwork.
How much can a sunroom contractor ask for up front in California?
Under the Contractors State License Board's rules, a down payment can be no more than $1,000 or 10 percent of the total contract price, whichever is less. Every other payment has to be listed in the contract and match work already done or materials already delivered to your home.
Does a heated sunroom count as an addition in California?
Yes, California's Energy Code treats adding heating or cooling to a space that didn't have it as an addition, so a sunroom you plan to heat or cool gets planned as an addition under that code. The industry's sunroom specification also counts a heated or cooled room that opens to the house as regular living space.
Do I need solar panels if I add a sunroom in California?
No, the Energy Commission says the code's solar panel rules don't apply to additions or alterations. That covers a sunroom built as an addition to your house.
