I measure your patio, check the slab and roofline, and ask how you'll use the room.

A lot of the houses I walk around in Upland have some years on them, and some sit in the city's historic districts, so the first thing I look at is how the back of the house was built and what's been added since. You'll also find newer neighborhoods where the slab and roofline are easier to predict, but even there plenty of homeowners already have a patio cover or a deck they'd like to turn into a real room. Either way the house sets the limits, because a sunroom ties into your wall and roof and sits on whatever slab or footing is under it.
It's the same kind of work we do next door in Rancho Cucamonga and down in Ontario, but more of my visits here start with an honest question about whether the house can carry the room you have in mind, and what might need fixing first.
What to know before building a sunroom in Upland
Building permits in Upland go through the city's Building and Safety Division, and on a sunroom the schedule usually turns on that review more than on the build itself. Contractors working in Upland need a current city business license, so it's fair to ask whoever you're talking to for that along with their contractor's license. We're licensed and fully insured, and when your job needs a permit, we put the paperwork together, submit it to the city and meet the inspector for each visit.
What moves the price is the kind of room you want and the shape of what's already out back, and what moves the schedule is the permit review, any prep on the slab or deck, and on some older houses an extra design review I explain in the questions below. Your own figure comes from the estimate visit, once I've seen the house. We work across Riverside and San Bernardino counties, from Upland to Home Gardens and Chino, so the crew that shows up here has worked on plenty of patios like yours.

Patio-to-sunroom conversion
A lot of Upland backyards already have a concrete patio off the family room, and turning it into a sunroom is often the simplest way to get a real room out of the space. I check whether that slab can carry walls and a roof before we plan anything, because a patio poured for chairs isn't always ready for a room.
Deck-to-sunroom conversion
Where an Upland house has a raised deck off the back, a deck-to-sunroom conversion can turn it into a room you'll actually use. We look at the posts, beams and footings first, since most decks were built for people and furniture, not glass walls and a roof.
Three season sunrooms
If what you want is a covered, bug-free place to sit most of the year, a three-season room over your patio does that without the cost of a fully insulated room. We'll talk through how you'd use it, because that's the honest way to tell whether you need more room than this.
Four season sunrooms
When you want the room to feel like part of the house, a four-season room gets insulated walls and roof and ties into your home like an addition. On older Upland houses that means a closer look at where the new roof meets the old one and how the wall it attaches to was framed.
Patio cover installation
Some Upland homeowners don't need walls at all, just shade over the slab, and a patio cover is a lot less work than a full room. We size it to your house and roofline so it looks like it belongs, and if you think you'll enclose it someday, tell me now so we build it with that in mind.
Sunroom remodeling
Plenty of older houses in Upland already have a sunroom or enclosed patio from years back, often with tired glass, leaks or a roof that's showing its age. I'll tell you honestly whether it's worth fixing what's there or whether starting over makes more sense.

Frequently asked questions
Do I need a permit to build a sunroom in Upland, CA?
Don't assume you don't, because the city's list of projects that need no permit names fences 6 feet or less and block walls 2 feet or less, and sunrooms aren't on it. The Building and Safety Division is the place to ask about your address, and it's one of the first things I sort out before we plan the build.
How do I apply for a building permit in Upland for a sunroom?
You apply online, because Upland's building division only takes permit requests that way. The application asks for the contractor's license and business license to be uploaded, and a PDF or a JPEG photo works, so on our jobs we put that package together and send it in for you.
Does my older home in Upland need extra review before adding a sunroom?
It does if your house is a designated historic resource, because exterior changes that alter its appearance need a Certificate of Appropriateness, the city's approval of the design, from the Planning Division. Upland has nine local historic districts, so if your house might be in one, confirm it before anyone draws up plans.
What wind and rain does a sunroom in Upland need to be built for?
The city's building page lists a design wind load of 110 mph and design rainfall of 4 inches an hour, and Upland builds to the California Building Code. On a sunroom that shows up mostly in how the roof is fastened down and how the gutters and drainage are sized, so we plan those around the city's numbers.
How much does a sunroom cost in Upland?
The price comes down to the type of room, its size and what it's being built on, and you get your own figure at the estimate visit. A screen room or three-season room over a solid patio costs less than a four-season room with insulated walls, more glass, wiring and a roof tied into yours. Prep on an old slab or deck, or a design review on a historic house, can add to it too.
How long does it take to add a sunroom in Upland?
Most of the wait usually comes before the build, while the permit request, any historic design review and any prep on the slab or deck get done. After that it depends on the room, since a screen room goes up quicker than a fully insulated four-season room, and I'll walk you through the timing for your house at the estimate.
