Colton patios and the ground under them
Colton sits between Rialto and San Bernardino, with the Santa Ana River running through it and Reche Canyon off to the southeast. Most of what we see here are single-story houses on modest lots, some older ones closer to the middle of town and newer tracts farther out. Nearly all of them have a concrete patio out back and a cover that's had a long life already.
That slab is usually where the room starts, so the first thing I want to know is whether it was poured to carry walls and glass or just a grill and a few chairs.
Working in Colton: what the city checks and what we handle
A sunroom enlarges your house, and in Colton the Building & Safety Division issues the permit for that and runs the plan check and inspections, so the city's review sets part of the schedule before anyone frames a wall. Two things are worth checking on any contractor you talk to. They should hold a state license from the Contractors State License Board, and a City of Colton business license, which anyone doing work inside city limits needs. The city won't give your permit final approval until every contractor on the job is on its list with a city license, so it's better to ask now than at the last inspection.
We're licensed and fully insured, and when a job needs a permit we pull it in our name, draw it up and handle the inspections and the back and forth with the city, because nobody should have to learn plan check on their own house. Price mostly comes down to the room's size, how much of it is glass, whether your slab can carry it or needs new footings, and whether it's built for three seasons or all year. The schedule turns on the city's review, the drawings and any electrical or heating and cooling work, which we bring licensed trades in for. We do the same work up in Upland and across the cities around Fontana, and we deal with whichever office covers your address.
What do Colton patios need before they become rooms?
Most calls here start with a patio nobody uses much, a slab out back under an aluminum or wood cover that's sagging, rusting or sitting too low to hang windows under. Usually the old cover comes off, and the slab gets a hard look before we decide whether the room can sit on it or needs footings of its own. I'd rather you hear that at your kitchen table than halfway through the build.
Shaking is a real concern in Colton, because the San Jacinto fault zone runs through the city. A sunroom is a lot of glass on a light frame fastened to your house, so what it sits on and how it ties into the wall matter more than the trim, and we settle both in the drawings before the city ever sees them.

Sunroom work we do in Colton
Patio-to-sunroom conversion
Plenty of Colton houses already have a slab and a tired cover out back, which makes a patio-to-sunroom conversion the most common job we do here. We check whether the slab can carry the room, then build on it or add footings where it can't.
Sunroom additions
When there's no patio worth keeping, a sunroom addition gives the house a new room built from the ground up. We plan the foundation and the tie into your wall first, because that's what holds the room steady when the ground moves.
Patio enclosures
A patio enclosure closes in the space you already use with windows and walls, so it costs less to plan than a full addition. We set it up so the room matches how you'll actually use it, from a reading spot to a place for the dog.
Patio cover installation
A lot of older covers in Colton are past fixing, and some homeowners want shade now and walls later. We build new covers sized and framed so they can be enclosed down the road without starting over.
Screen room installation
A screen room keeps the open-air feel of the patio while keeping the bugs out, and it's a lighter build than a glass room. We frame it so you can swap screens for windows later if you change your mind.
Sunroom remodeling
Some Colton homes have a sunroom from years back with leaky seals, stuck windows or a roof that never quite worked. We figure out what's worth keeping, then replace the rest so the room gets used again.
How it goes when you call us about a Colton sunroom
Call or send the form
You call (909) 346-1870 or use the form and tell us a little about the patio or deck. We set a time for me to come out, and it helps if you're home for it.
I look at your patio
I walk the slab, the house wall and the yard, and we talk about how you want to use the room. You get a written quote that says what's in the price and what isn't, so the number doesn't move on you later.
We draw and permit it
We handle the drawings and pull the permit with the city, which runs its own plan check before we can start. The schedule we give you already counts that review instead of pretending it isn't there.
We build, then walk through
Our own crew builds the room, with licensed trades for any electrical or heating and cooling work, and the city inspects along the way. When it's done, I walk the finished room with you.

Send the form and we'll reply within one business day to set up a visit at your Colton home. I come out myself to look at the patio and the house, and the quote is free and in writing with no obligation. If it isn't the right fit, that's the end of it.

Questions about sunrooms in Colton
Do I need a building permit for a sunroom in Colton, CA?
Expect one, because Colton requires a building permit to build or enlarge a structure, and the city's list also names patio covers, decks and window installation. The list isn't complete, so specific questions go to the city's building office at (909) 370-5079. When we do the job, we pull the permit in our name and handle the inspections.
How do I check that a sunroom contractor can work in Colton?
Ask for two things, a California contractor's license from the state board and a City of Colton business license. Anyone doing work inside city limits needs the city license, and your permit won't get final approval until every contractor on the job is on the city's list with one.
What is the most a contractor can ask for up front on a sunroom in California?
State law caps the down payment at $1,000 or 10 percent of the contract price, whichever is less. Every other payment has to be listed in the contract and tied to work done or materials delivered, so if someone wants half before the first post goes in, that's your answer.
How much does a sunroom cost in Colton?
The price comes down to the size of the room, how much of it is glass, whether your existing slab can carry it and whether it's built for three seasons or all year. Electrical or heating and cooling work adds licensed trades, and a lot near mapped soft ground can change the foundation. After I see your place, you get a written quote that lists what's in it and what isn't.
How do I build a sunroom near the Santa Ana River or Reche Canyon in Colton?
You plan the foundation first, because the city maps areas along both banks of the Santa Ana River and in the Reche Canyon areas as prone to liquefaction, which is loose, wet ground losing its strength in a quake. If your lot is in one of those areas, I'll tell you at the walkthrough, and we work out what the room sits on in the drawings before the city reviews them.
What building code does Colton use for a sunroom permit?
New permit applications in Colton are checked against the 2025 California Building Standards Code, which has applied since January 1, 2026. If you're holding older plans from a contractor who never got started, expect them to need updating before they go in.

Getting the drawings started early means the city's plan check runs while you're still choosing windows, not after.
