About Riverside, CA
Riverside is a big city, and you can see that from job to job here. One week we're behind an older house a few minutes from downtown and Mount Rubidoux, and the next we're in a newer subdivision with a block wall and a tidy patio slab, and both owners usually want the same thing, a room off the back of the house they'll use every day. It's a short drive down from our base through Grand Terrace, so as a sunroom contractor in Colton, CA, we count Riverside as part of our regular week.
What we find out back usually decides the job. Plenty of houses here already have a covered patio or a raised wood deck, and some have an enclosure someone added years ago, so before we talk about glass or roof styles I look at what the room will sit on and where it meets your house.
Services in Riverside, CA
Patio-to-sunroom conversion
A lot of Riverside backyards already have a concrete patio under an aluminum or wood cover, and that's often the easiest place to start a room. We check whether the slab can carry walls and framing, and if it can't, we tell you what has to change before we price the rest.
Custom sunrooms
Older houses here often have rooflines and window spacing that a standard kit doesn't fit cleanly. Our custom sunrooms are sized and shaped around your house and how you'll use the room, so it looks like it was meant to be there.
Sunroom remodeling
We see a fair number of patio rooms that were closed in a long time ago and now leak where they meet the house or end up as storage. We can often keep the parts that are still sound and replace the windows, roof panels or flooring that aren't.
Deck-to-sunroom conversion
On sloped lots the back door often opens onto a raised wood deck instead of a slab. We look at the posts, beams and footings first, because a deck built for chairs and a grill isn't always ready to hold a room.
Patio cover installation
Some homeowners here just want shade over the patio and aren't ready to close it in. We build covers that tie into the house properly, and we can plan one so walls can be added later if you change your mind.
Screen room installation
If you mostly want to sit out back in the evening without the bugs, a screen room gives you that for less than a full glass room. I'll tell you honestly whether that fits how your family will use the space or whether you'd outgrow it.
Working in Riverside: permits, licenses and what sets the price
Sunroom permits here come from the City of Riverside's Building & Safety Division, because the city requires a permit for building onto or altering a structure, and a room added to your house falls under that. Most applications need a sign-off from the city's Planning Division before Building & Safety starts plan check, so the paperwork has two stops, and that is usually what sets the start date more than our crew does. The city also requires a City Business License for businesses working inside its limits, so it's fair to ask any contractor you're talking to whether they have one and whether they're licensed and insured, and we're licensed and insured.
We confirm which office covers your address, prepare the plans and handle the paperwork, and because a residential permit in Riverside goes invalid if work doesn't start within 12 months of issuance, we line the application up with when the build is actually on our calendar. Each city has its own building office, which is why we check the address first on jobs in Rancho Cucamonga and Redlands too. What moves the price is mostly the size of the room, whether it's a screen room, a three season room or a fully insulated four season room, and what it has to sit on, since a slab or deck that needs work adds cost before the first wall goes up, and your written estimate gives you your own figure.
Riverside, CA properties and local conditions
The houses we work on in Riverside range a lot in age, and the older ones tend to have back patios that were poured for chairs and a barbecue, not for walls. A thin slab, a little settling toward the yard, or a cover bolted into the eave years ago can all look fine until we measure, so I check for level, cracking and how the new roof will tie in before I write anything down. When the slab needs help, we tell you plainly whether to repair it, add footings or start fresh, and why.
Some lots here slope, and the patio sits above a low retaining wall. The city lets walls up to 4 feet go without a permit, measured from the bottom of the footing to the top of the wall, but not once the wall is holding up extra load, so if your room would sit close to that wall, we look at it during the estimate and decide with you whether to set the room back or include the wall in the plans.

What happens after you call us about a Riverside sunroom
Call or send a message
Call (909) 679-6010 or use the form, and we'll set a time for me to come out. It helps if you're home for the visit so we can talk about the room together.
I look over your site
I check the slab or deck, where the room meets your house and how the roof will tie in, and I ask how you'll actually use the room. You get a written estimate, and I'll go over any line on it as many times as you want before you decide.
We handle plans and permits
Once you're ready, we prepare the plans and take the paperwork through the city's planning sign-off and plan review. That review sets the start date more than we do, so we'll keep you posted while it's in.
We build and walk through
Our crew builds the room, and we set up the city inspections along the way. When it's done, I walk through the finished room with you so you can see how everything works.
Frequently asked questions
Do I need a permit to build a sunroom in Riverside, CA?
Plan on it, because the City of Riverside requires a building permit for building or altering a structure, and a room added onto your house falls under that. The city's exempt list covers finish work like painting, tile, carpet, cabinets and counter tops, not new rooms. We confirm what your address needs, prepare the plans and set up the inspections.
How do I get a building permit for a sunroom in Riverside, and who can apply?
The city can issue many types of permits to the property owner, the owner's authorized agent or an appropriately licensed contractor, and applications can be made at the Permit Services counter in the city's One Stop Shop. When you hire us, we take care of that part, since we're already drawing the plans and scheduling the inspections.
How long does it take to get a patio cover permit in Riverside?
A simple patio cover is one of the permits the city can issue the same day, over the counter. Other projects may need plans submitted for plan review, and a sunroom with walls, windows and a door is more than a simple cover, so plan on that review. If you only want shade, ask at the estimate whether your cover looks simple enough to qualify.
Does a small sunroom under 120 square feet need a permit in Riverside?
Don't count on an exemption, because the city's 120 square foot rule covers one story detached sheds, playhouses and similar structures, not a room attached to your house. A sunroom built onto the house is work on the house itself, which the city's permit rules cover. If you're thinking about a small detached screen room instead, we'll check with the city before anyone assumes it's exempt.
Does a contractor based outside Riverside need a city business license to work there?
It may, because an older city Finance page says businesses located outside the city limits may also be required to get a City Business License. For current details, the city's Business License Division answers questions about the license, and the Business Tax Office takes business tax questions at (951) 826-5465.
How much does a sunroom cost in Riverside, CA?
You get your price in a written estimate after I've seen your house, because the biggest cost factors are things I can only judge on site. Reusing a sound slab or deck keeps the cost down, while one that needs footings or rebuilding adds to it, and a four season room with insulated walls and glass costs more than a screen room on the same footprint. If you're torn, I'd rather see you build a well-sized room you'll use every day than stretch for the biggest one.
