Request an estimateRancho Cucamonga: three old towns grown into one
Rancho Cucamonga grew out of three older towns, Alta Loma, Etiwanda and Cucamonga, and each part still keeps some of the feel of its old town center. A lot of the city filled in fast during the 1970s, when families from Los Angeles and Orange County came looking for homes they could afford, so the neighborhoods run from that building wave to newer streets.
That mix matters for a sunroom, because the house decides a lot about the room. We see the same spread next door in Upland and Ontario, and it's why I start every visit at the back wall. On an older home I'm usually looking hard at the patio slab and the roofline before we plan anything, and on a newer one the bigger question is often how a room fits the yard without crowding it.
Working in Rancho Cucamonga: permits, licenses and what sets the price
The City of Rancho Cucamonga issues building permits here, and when your job needs one, the city's review usually sets the start date more than our crew does. When that's the case, we put the paperwork together, submit it to the city and meet the inspector for each visit. Before you hire anyone, look up their state contractor license with the Contractors State License Board and ask about their city business license too, because those are two separate licenses. We're licensed and fully insured, and I'm happy to show you both.
Price comes down to the size and type of room you want and how much prep your house needs before we build, and the schedule turns on design choices, the permit review and when materials arrive. Your own number comes from the estimate, once I've seen the house. We're based in Eastvale and work across the cities around it in Riverside and San Bernardino counties, so heading up to Rancho Cucamonga is as routine for us as a job in Norco.

Patio-to-sunroom conversion
Plenty of homes here already have a covered patio out back, and closing it in is often the simplest way to get a real room. I check the slab and the existing cover first, because a conversion only works if what's there can carry walls and glass.
Sunroom construction
When the patio can't be reused or you want the room somewhere new, we handle the full sunroom construction, from the footing to the last piece of trim. We plan how the roof ties into your house before we order anything, since that joint is where add-on rooms most often go wrong.
Four season sunrooms
Some families want a room they'll use as a den or a playroom every month of the year, not just on nice afternoons. A four season room gets insulated walls, roof and glass so it works like the rest of the house, and that's also why it costs more.
Screen room installation
If what you really want is evenings outside without the bugs, a screen room may be all you need, and I'll tell you so. It's a lighter build than a glass room and still leaves you the option of closing it in later.
Patio cover installation
A lot of backyards we see are bare concrete or have an older cover that's past its best. We build new patio covers sized to the yard and attached so water runs away from your house, not toward it.
Sunroom remodeling
Older homes around the city sometimes come with a patio room added years ago that now has foggy glass, tired framing or a leak where it meets the house. We figure out what's worth keeping before anyone talks about a teardown, because a remodel is sometimes the honest answer.

Frequently asked questions
Do I need a permit for a patio cover or sunroom in Rancho Cucamonga?
Patio covers are on the list of work the City of Rancho Cucamonga issues permits for, so plan on one for a new cover. The city's list doesn't name sunrooms or enclosures, so for those the place to ask is the city's Building & Safety office, where permits are applied for online. When your job needs one, we handle the filing as described above.
Does a contractor need a business license to work in Rancho Cucamonga?
Yes, the city requires a business license of anyone doing business in Rancho Cucamonga, and it has to be in place before the work starts. The city's Business Licensing office issues and renews those licenses every year, and contractors from outside the city, like us coming from Eastvale, list the job location and job value when they apply.
How much can a contractor ask for as a down payment on a sunroom in California?
Under state contractor board rules, a down payment on a home improvement job can't be more than $1,000, and on a smaller contract the cap drops lower because it's tied to a share of the contract price. After that, each payment should be spelled out in the contract and based on work done or materials delivered, so if someone wants half up front for a sunroom, that's a good reason to slow down.
What makes a sunroom cost more or less in Rancho Cucamonga?
The biggest difference is the type of room, because a screen room or patio cover is a much lighter job than a fully insulated four season room with glass and electrical. After that it's whether your slab and roof edge can be used as they are or need work first, which I can only tell once I've looked. If a simpler room fits how you'll use it, I'll say so at the estimate.
How long does it take to get a sunroom built in Rancho Cucamonga?
Most of the wait usually comes before the build, while we settle the design, order the room and get through the city's permit review if your job needs one. Once materials are here, the size of the room and any slab work decide how long our installers are at your house, and I'll walk you through the timeline for your job at the estimate.
What is the best way to turn a covered patio into a sunroom?
The best way is to find out first whether the slab and the existing cover can carry walls, windows and a sealed roof, because that decides whether you're converting or starting fresh. If they can, a conversion usually saves work, and if they can't, it's better to know before you buy anything. Call (951) 416-3048 and I'll come take a look.
