All season rooms in Whittier CA - a room you can use in July and January
Patio too hot in July and too cold in January? We build a room off your house you can heat, cool and use all year.
Is an all season room right for your Whittier home?
All season rooms in Whittier, CA are sunrooms with closed-in walls that open to your house and are built to be heated and cooled, so you get a real room you can use in July and January, not a porch that only works in spring.
Most people who call us have a patio, slab or deck they like but can't use half the year because it's too hot or too cold out there. The price moves with the size of the room, the glass, how you'll heat and cool it and what shape the base and the house wall are in, and the schedule turns mostly on permit review and on whether the city or the county handles your address. You get the figure for your own room in the written estimate after my visit, so you can look it over at home.

What all season rooms look like
How we build an all season room
It starts with how you'll actually use the room. Is it an office, a reading spot or a place for the whole family on a cold night? The whole point of this room is July and January, so we talk through how you'll heat and cool it and which glass fits that plan before anything gets ordered, because I'd rather settle those choices at the start than open a wall back up later. Then we look hard at the slab or deck and the house wall, since the base under the room and the spot where it meets the house are where a job like this is won or lost. Our crew builds the frame level and square, ties it into the house, sets the roof, glass and doors, then cleans up and walks you through the finished room.
Not every room needs to be an all season room. If you mostly want spring and fall evenings out of the wind and don't plan to heat or cool the space, an enclosed patio room is the simpler build. If you want glass overhead as well as on the walls, ask about solarium installation, and we'll talk through what all that glass means for keeping the room comfortable.
Why Whittier homeowners call Sunscape Whittier Sunrooms & Patios for all season rooms
I do the visit myself
I come out myself to look at the job, measure and talk it through with you, and I'm on site leading our own small crew during the build. The person who explained the plan is the one making sure it gets built that way.
Licensed and insured in California
We're licensed and insured. The Contractors State License Board is the state office that licenses and oversees the building trades in California, so you're hiring a crew that answers to it.
Building around Whittier since 2021
I started this business in Whittier in 2021, and we work here and in the cities around it, including the unincorporated county areas nearby. That matters on a room like this because the city and the county each run their own permits, and we deal with both.

What happens after you call about an all season room?
Call or send the form
Call (562) 203-1022 or send the form with your address and a line on how you'd use the room. We set up a time for me to come out.
I come out and measure
I look at the patio, slab or deck and the wall the room will join, and walk you through the room types and what each one means for how you'll use it. The estimate comes in writing, so you know what you're paying for before you decide anything.
We sort out the permit
We find out which office handles your address and take care of the permit paperwork. We keep you posted on where things stand while it's under review.
Our crew builds the room
Our own crew builds it from start to finish with me on site, and I meet the inspector for each visit, which in Whittier usually means several, each booked at least one business day ahead. Keep the job card and approved plans out of the sun and handy, since the inspector looks at them every time.
All season room questions
How much does an all season room cost near Los Angeles?
A sunroom addition in the Los Angeles area usually costs about $25,000 to $65,000 for the whole project. Where a room lands in that range depends on its size, the glass and how you'll heat and cool it. Your own figure comes from the written estimate after I've seen your slab or deck and the house wall.
How do I find out who issues the permit for a sunroom in Whittier?
If your home is inside city limits, the City of Whittier issues the permit, and if it's in unincorporated LA County, LA County Public Works does. In the city, the Planning Services Division looks at the project before the plans go to Building & Safety for review, and the city suggests talking with both before you enlarge your house. Since an all season room adds onto the house, that's the order we follow.
What makes a sunroom usable all year?
A room you can use all year has closed-in walls, opens to the house and is built to be heated and cooled, which is why one industry standard treats it as real living space. Under that standard, its windows and doors meet requirements for air leaks, water leaks and heat loss, so it's fair to ask any contractor whether theirs do. The same standard also calls for the frame to be designed for earthquake forces.
What is the best glass for an all season room?
Insulated glass is the right pick for a room you'll use in every season. One sunroom maker, for example, offers single-glazed glass for 3 season use and insulated glass for 4 season performance. Single glass only makes sense if you're really after a spring and fall room.
How much can a contractor ask for up front on a sunroom in California?
Under the state's rules, a contractor can't take a down payment of more than $1,000 or 10 percent of the contract price, whichever is less. The rest of the payments are listed in the contract and tied to work done or materials delivered, so you pay as the room takes shape.
Does the Whittier wildfire hazard map affect adding a sunroom?
It may. The city says the state's updated wildfire hazard map shows how likely wildfire is in certain areas, not current fire conditions. It also says the map may affect insurance, building codes and defensible space requirements going forward, so it's worth knowing where your lot sits before you plan a room on it.
