Sunroom Contractor in Chino, CA - A Room Out Back You Can Use in August

Chino's Building Division issues permits for all work except a short list of exemptions, and a sunroom isn't among the examples the city gives. Those examples are things like painting, wallpaper, carpet, tile and fixing a leaky faucet. The city advises calling the Building Division to find out whether your work needs a permit, and once you sign with us, we make that check for your address and handle the paperwork.

The city's permit FAQ, written before the current code, says a permit expires 180 days after it's issued, or 180 days after work stops or is abandoned. The Building Official can grant one 180-day extension at no cost, but only if a letter giving the reason arrives before the permit runs out. That's why we line up materials and the crew before the permit is pulled, so the work keeps moving.

Yes. Anyone doing business in Chino needs a city business license, and the city spells out that this includes contractors and service people from out of town. The license is good for one year, so it's fair to ask any contractor you're comparing whether theirs is current.

The state licensing board says anyone who builds or alters a structure in California must be licensed by it if the job needs a building permit, uses any extra workers, or runs $1,000 or more in labor and materials across one or more contracts. A sunroom clears that bar easily, so don't hire anyone who isn't licensed. We're fully licensed and insured.

For a room you'll use year round, I'd pick a four season room with an insulated roof and insulated glass, because Chino summers are long and hard on glass rooms. In a normal year the city sees about 99 days at 90°F or hotter, 23 of them at 100 or more, and around 11 nights at freezing or below. A three season room or a screen room costs less and works fine on spring and fall evenings, but expect to stay out of it on August afternoons.

It comes down to the size of the room, whether it's a screen room, a three season room or a four season room, and whether what it sits on can carry it. Reusing a sound slab and patio cover keeps the price down, while new footings, a new roof frame, power, or heating and cooling add to it. The schedule turns on the same things plus the city's permit review, and your written estimate spells out what we'd build and what it sits on.
