Request an estimateMontclair: older patios behind single-story homes
Montclair is mostly single-story homes on compact lots, many of them older houses with a concrete patio off the back door and a cover that's seen better days. Space is tight behind a lot of these houses, so a sunroom here usually goes where the patio already is instead of out into the yard. The neighborhoods feel a lot like the ones over in Ontario and up in Upland, and the same questions come up on nearly every call.
The ground under the room is where Montclair jobs get decided, because an old patio pour often wasn't made to hold walls and a roof. I'd rather check the slab before we talk about windows.
Building a sunroom in Montclair: permits, licenses and price
Sunroom jobs here go through the city's Building Division, which issues the permit, reviews the drawings and sends inspectors out during the build, so the start date usually turns on plan review more than on our crew's calendar. Any licensed contractor can pull the permit, and at the City Hall counter they have to show their contractor license card along with their workers' comp carrier and policy number, so it's fair to ask to see both. Every business working in Montclair also needs a city business license that's good for one year, which is an easy thing to check before you sign anything.
When a job needs a permit, we prepare the plans, handle the city paperwork and keep you posted on where it stands, and I'll tell you at the estimate who's pulling it. We're licensed and fully insured, and we handle permits here the same way we do next door in Pomona. Price moves mostly with the size of the room, whether your slab or deck can carry it or needs new footings, and whether you want an insulated room you'll heat and cool or a lighter three season room, and the estimate is where you get your own figure.

Patio-to-sunroom conversion
Most Montclair calls start with a concrete patio under an old cover, and closing that space into a real room is the job we do most. We frame the walls and roof right on the existing slab when it's sound, and add footings where it isn't.
Sunroom additions
When the patio is too small or the slab won't hold, a sunroom addition on its own foundation gives you a full room tied into the house. We match the roofline and finish so it doesn't look tacked onto a single-story home.
Four season sunrooms
If you want a room you'll sit in every month of the year, the insulation in the walls, roof and floor matters more than the glass. We settle those choices at the start, because they're the expensive part to redo later.
Three season sunrooms
Plenty of homeowners here just want the patio usable more often without paying to heat and cool another room. A three season room keeps out wind, dust and bugs, and I'll tell you straight if that's all your space needs.
Deck-to-sunroom conversion
Raised decks are less common here than slabs, but where a house has one, we check the framing and footings before anything goes on top. Most decks need strengthening to carry walls and a roof, and we'd rather find that out at the estimate than halfway through.
Patio cover installation
Not every backyard needs walls, and worn-out patio covers are one of the most common things we replace in Montclair. We size a new cover to your slab and can plan it so it's ready to enclose later if you change your mind.

Frequently asked questions
How do I get a permit for a sunroom addition in Montclair?
You submit plans to the city, and for a room addition that means three sets of detailed plans showing the floor plan, elevations, framing and the electrical, mechanical and plumbing work, along with a plan check deposit. A brand-new structure is by appointment and takes five sets plus two copies of a soils report and structural calculations, and the city's building permit page walks through the steps. A draftperson can usually draw an addition, though bigger projects may need plans signed by a California-licensed architect or engineer.
Can I pull my own building permit for a sunroom in Montclair?
Yes, the city offers an owner-builder permit, but it's meant for owners doing the work themselves. You sign a form exempting you from workers' compensation insurance and agree to comply if you later become subject to those rules, so if you're hiring a crew to build the room, that route usually doesn't fit.
What building code does Montclair use for sunrooms?
Montclair builds to the current California Building Standards Code, with the California Residential Code covering homes and a set of city amendments on top. The city's design criteria also call for a high earthquake design rating, a 96 mph design wind and rainfall of 2 inches an hour, which is why the framing, roof connections and drainage on a permitted room are designed around them.
How do I find out if my house in Montclair is on sewer or septic?
Make a Public Records Request for your address's building permits, online or at City Hall, and the city will send you any permit records it has for a sewer connection. It's worth knowing before we plan an addition, because a septic tank and its lines limit where a new foundation can go.
How much does a sunroom cost in Montclair?
Your cost comes down to the room's size, what it sits on and how you'll use it, and I'll give you your own number once I've measured. A room on a sound slab costs less than one that needs new footings, an insulated four season room costs more than a three season one, and a new structure carries the extra plan sets and reports the city asks for.
What causes a patio slab to be too weak for a sunroom?
Most old patio slabs were poured thin with no thickened edge, because they only had to hold a table and chairs, not walls and a roof. Cracks, settling and a slope toward the house make it worse, so we check the slab at the estimate and either build on it, add footings around it or recommend a new foundation.
