Homes and backyards across Chino
Chino runs from older blocks near downtown, with ranch houses and patios added over the years, out to the newer tracts in the south end around The Preserve, where the houses are bigger and the yards are tighter to the lot lines. Most of our calls here start at the back of the house, with a slab or a tired patio cover the family wants to turn into a room they'll use. We see a lot of the same houses next door in Chino Hills and up in Ontario, where we're based.
Those two kinds of houses ask different things of a sunroom. On an older place the job usually turns on whether the slab or cover out back can carry a room, and on a newer one it's more about matching the roofline and stucco so the room looks like it came with the house.
Working in Chino: permits, licenses and what sets the price
The City of Chino's Building Division issues building permits for all work except what the codes carve out, so on a job that needs one, the city's plan review sets the pace before our crew can start. When your job needs a permit, we prepare the plans, file them with the city and schedule the inspections, and I'll tell you up front that review takes time. Before you hire anyone here, ask for two things, their California contractor license and their City of Chino business license. We're fully licensed and insured, and every job is backed by our satisfaction guarantee.
Chino sits right below us, so it's a short drive for me to come measure, and it's the same crew and the same way of building we use in Rancho Cucamonga. Your price moves with the size of the room, whether your existing slab can carry it or we need new footings, the roof and glass you pick, and whether the room gets power, heating and cooling. The schedule mostly turns on the city's review and when inspections come up, and your written quote spells out what's included.
Services in Chino, CA
Patio-to-sunroom conversion
A lot of Chino backyards already have a slab and a patio cover, and turning that into a real room is often the most direct way to add space. I check whether the slab can carry walls and glass before we plan anything, because a room is only as good as what it sits on.
Three season sunrooms
Plenty of Chino families don't need a fully heated room, just one that keeps out wind, dust and bugs for most of the year. Our three season sunrooms give you that without the insulation and heating and cooling work a year-round room needs.
Four season sunrooms
If you want to sit in the room on an August afternoon, it has to be built to hold out the heat, with insulated walls and roof and real cooling. We frame it like part of the house and bring in licensed electricians and heating and cooling trades where the job calls for them.
Patio cover installation
Some Chino yards just need shade over the back slab so that side of the house isn't baking all afternoon. We set the posts on proper footings and tie the cover to the house so it sheds water away from your wall.
Sunroom remodeling
Older add-on rooms around town often leak where they meet the house or feel like an oven by June. We open up the problem spot, fix the joint or the roof, and swap in glass and panels that handle the heat better.
Patio enclosures
On the newer tracts in the south end, owners often want the covered patio closed in without a full addition. We enclose it with walls and windows that match the house, so it reads as part of the home and not a kit bolted on.
What Chino's summer heat asks of a sunroom
Chino gets hot. In a normal year about 99 days reach 90 degrees and 23 of those hit 100 or more, so a glass room facing the wrong way can turn into a greenhouse by noon. We look at which way the room faces, pick the glass and roof panels for that, and plan shade and cooling before we talk about trim.
The other thing we watch is the joint where the new room meets the old house. Rain doesn't come often here, so a sloppy flashing job can sit for months and then show up as a ceiling stain in the first big storm. I'd rather spend an extra hour on that joint than have you find it that way.

We handle plans and permits
Once you sign, we draw the plans, file them with the city and keep you posted while review runs. The city asks for inspection requests before 3 pm for a next-day visit, so we book ours early to keep the crew moving.

Our own crew does the building, with licensed electricians and heating and cooling trades coming in where the job needs them. When it's done, we walk the finished room with you.
Chino sunroom questions answered
Do I need a permit to build a sunroom in Chino, CA?
Chino requires a building permit for all work except what the codes exempt, and the city's older FAQ gives small jobs like painting, carpet, tile and fixing a leaky faucet as its examples of exempt work. A sunroom isn't that kind of job, and the city's advice is to call the Building Division at 909-334-3250 to confirm for your project. When yours needs one, we prepare the plans and file them for you.
How long does a building permit last in Chino?
A Chino building permit expires 180 days after it's issued, or 180 days after work stops or is abandoned, according to the Building Division's older FAQ. The building official can grant one 180-day extension at no cost, but only if a letter giving the reason arrives before the permit expires. We keep inspections booked as the work goes so the permit stays active.
Does an out-of-town contractor need a Chino business license?
Yes. Anyone doing business in Chino needs a City business license, and the city spells out that this includes contractors from out of town. It's a fair thing to ask any contractor before they start on your house.
When does a contractor need a California state license to build a sunroom?
California's Contractors State License Board says anyone who builds or alters a structure must hold its license if the project needs a building permit, uses any other workers, or costs $1,000 or more in labor and materials across all its contracts. A sunroom clears that bar, so ask any contractor you're considering for their state license.
How much does a sunroom cost in Chino, CA?
It comes down mostly to how big the room is, what it sits on and how much it has to do. A three season room on a sound existing slab costs far less than a four season room that needs new footings, insulated walls, power and cooling, and plans and permit fees add to any job that needs them. I'll give you a written figure once I've seen the site.
How do I find out if my house in Chino is in a fire hazard severity zone?
Start with where you live, because the newer fire hazard severity zone map placed only some areas of southern Chino in a zone, including parts of The Preserve and around Prado Dam, rated Very High, High or Moderate. Chino Valley Fire keeps the map, and if your house is down there, I look your lot up before we draw any plans.
