What goes into adding a sunroom to a house in Colton?
A sunroom addition is an enclosed room added onto your house. It can be anything from a screened room to a fully enclosed room that's heated and cooled, and in Colton we build each one to join your home cleanly and fit the way you'll use it.
Most people call me because a patio sits empty half the year, a deck gets too hot to stand on, or they need another room without moving. The price mostly comes down to the size, whether the room is heated and cooled, whether your slab or deck can carry it or needs a new foundation, and which windows and insulation you choose. The schedule mostly depends on the city's plan review and any other department that has to sign off, and once I've seen the space, your written estimate gives you your own figure. If your patio already has a cover, a patio-to-sunroom conversion may be the simpler route.
How we build a sunroom addition
Adding a room means fitting it to the house you already have, so before I suggest a room type I look at where it will join, how you'll get into it and how you'll use it. Then we settle the windows and the insulation in the walls, floor and roof with you, because those are much easier to put in while the room is being built and often cost more to add later. Once you've signed off, we prepare the plans. Our crew builds the room on your existing slab or deck, or on a new foundation when the base can't carry it, and ties the roof into the house so water runs off instead of in.
Most additions end up as one of two kinds of room, and we build both. If you already know which way you're leaning, our pages on four season sunrooms and three season sunrooms go into each one in more depth.
A four-season room for daily use
This is the one to pick if the room will be your office, your dining room or the place you sit in August, because it's built to stay comfortable in any weather. It costs more, so I only steer people to it when they'll really live in it.
A three-season room for milder months
This suits morning coffee, plants or keeping bugs off the patio, when you don't need the room through the hottest and coldest stretches. It skips the heating and cooling, which keeps the price down.
Getting a sunroom addition approved and built in Colton
Colton's Building and Safety Division handles plan check, permits and inspections, and room additions are on the city's residential plan check list, so expect your addition to go through review. Many permits also need sign-off from the Planning Division or another department before plans go in online, and the city asks people to talk with its staff first, so we do that before we upload a single drawing. California's energy standards cover home additions too, which matters most for a heated and cooled room. If your lot sits inside a state earthquake fault zone, the city requires a geologic investigation before permitting most buildings people occupy, to show the room won't sit on an active fault. When your project needs a permit, we confirm which building office covers your address, prepare the plans, handle the paperwork and set up the inspections.
We're based in Colton, and around here most of the rooms we add go onto a back patio slab or an older covered patio. The long, hot summers mean we think hard about which way the glass faces and how much shade the roof gives. We see the same patios and the same heat on jobs in San Bernardino and Redlands.

Frequently asked questions
How much does a sunroom addition cost near Colton, CA?
A three-season sunroom built on an existing base in the San Bernardino area usually costs about $95 to $140 per square foot, installed. That usual price leaves out insulation, extending your heating or cooling, plumbing and pulling permits, so expect those to add to the total. Larger rooms that need a foundation and heating and air conditioning fall at the higher end of what sunrooms cost. Your written estimate gives you the figure for your own room.
What is the difference between a three-season and a four-season sunroom?
A four-season sunroom is fully enclosed, heated and cooled, and has all-weather windows. A three-season room usually isn't heated or cooled and has uninsulated windows or screens, which is why it costs less and gets less use in the hottest and coldest months.
How much can a contractor ask for up front on a sunroom addition in California?
California caps a home improvement contractor's down payment at $1,000 or 10 percent of the total contract price, whichever is less. Every other payment has to be listed in the contract and tied to work completed or materials delivered, so your payments follow the work.
How do I compare sunroom quotes from different contractors?
Check that each quote covers what the usual price includes, which is labor, standard-grade windows, siding, roofing, fixtures and electrical access. Then look at how each one handles insulation, heating and cooling, plumbing and permits, because that's where two quotes for the same room can drift far apart.
What is the best way to decide how big a sunroom should be?
Start from how you'll use the room and what has to fit in it, then size it to the wall it joins and the yard you still want to keep. Bigger isn't always better, since the price climbs with every square foot, and I'd rather build you a room you fill than one you're paying to heat and cool for nothing.
Can a sunroom be added on top of my existing patio slab or deck?
Often it can, if the slab or deck is level, sound and strong enough to carry walls and a roof. I check that at the estimate, and when it can't carry the room, we build a new foundation, which adds to the price.
