Sunroom additions in East Hemet CA - a sealed room you'll use all afternoon
A patio or back wall you rarely use in the heat becomes a bright, shaded room with tight seals that your family sits in.

What does a sunroom addition in East Hemet involve?
A sunroom addition in East Hemet is a glass-walled room built onto your house. It can be anything from a simple room with no heating or cooling to one that works much like a regular room addition. Built well, it turns an unused patio, deck or back wall into space your family uses.
Most people who call me have a patio, a deck or a quiet back wall that gets more sun than use, and they'd like a room they'll actually sit in. The price mostly depends on the size of the room, whether it gets its own heating and cooling or joins the house, the condition of the slab or deck it sits on, and how much glass and shade the sunny sides need. The schedule mostly depends on the permit and on any work the base needs first, such as new footings under a deck. If you're starting from a concrete patio, our patio-to-sunroom conversion page covers that route, and either way I'll give you a written estimate for your own room once I've seen it.

What sunroom additions can look like
How we build a sunroom addition
The first thing I settle with you is whether the room stands apart from the house with its own heating or cooling, or joins the house like any other room, because that choice decides the doors, the glass and much of the cost. In the same conversation we plan how any walls facing east or west will be shaded, since a room that grows too warm by midafternoon is a room nobody sits in. After that we prepare the base the room needs, set the frame against your wall, roof it, and put in the glass. We seal every corner and joint with care, because one leaking corner can spoil the whole room.
If you'd like a room you can use in every month of the year, with heating and cooling planned in from the start, our four season sunrooms are built for that. If you mostly want shade and shelter from the wind from spring through fall, three season sunrooms are a lighter build and suit many patios here.
Why East Hemet homeowners call East Hemet Sunrooms & Patios for a sunroom addition
I do every estimate myself
I come out to measure and look at your house myself, and our crew does the work with me on site. When a room needs electrical or heating and cooling work, we bring in licensed trades for it, so each part is done by people who do that work every day.
Window and door work behind seals
I spent many years installing windows and doors for other companies before I started building sunrooms here in East Hemet in 2023. That work taught me how water and heat get through the smallest gap, which is why the glass and seals get the most attention on our jobs.
Licensed and fully insured, every job
We're licensed and fully insured. A sunroom addition brings framing, glass, roofing and often electrical work together, and California's licensing board ties that kind of multi-trade enclosure to its general building license, so it's fair to ask any builder which license they hold.
Permits handled with Riverside County
East Hemet is one of the county's unincorporated communities, so a sunroom permit here usually starts with the county's building office. We check what your address needs, and when a permit is required we prepare the application and plans and meet the inspector on site.
On a sunroom addition, the seals and the shade decide whether you'll use the room, so I'd like to see your house before we talk about anything else. Send us your address or call (951) 484-2079 to set a time.

What happens after you call about a sunroom addition
Call or send the form
Call (951) 484-2079 or use the form, and tell us your address, whether the room would sit on a deck or a slab, and which way the wall faces. We get back to you to set a time for me to visit.
I visit and measure
I look at the base, the wall the room will join and how the sun falls on it, and we talk through how you'd like to use the space. You then get a written estimate for that room, so you can weigh the cost before you decide anything.
We handle permits and build
Once you decide to go ahead, we look after the permit side with the office that covers your address. Then our crew builds the room.
Walk through the finished room
We walk through the finished room with you and check the doors, glass and seals together. I'll also point out the roof and gutters, since one maker's owner guide suggests inspecting them once a year and staying off the roof unless you need to be up there.
Sunroom addition questions
How much does a sunroom addition cost near East Hemet?
Building a sunroom in the Riverside area usually costs about $95 to $130 per square foot. That's the going rate in the area, not our price. Your own figure depends on the size, the type of room and the base it sits on, and I'll give you a written estimate after I've looked at your house.
Do I need a permit for a sunroom addition in East Hemet?
Check with the county before anything is built. The Riverside County Building & Safety Department issues permits for the work on its permit list, and the list includes both enclosed patios and additions and alterations. If you'd like to call the county yourself, its directory lists Halimah Shenghur for District 3, which includes East Hemet, at 951-955-3250, though staff listings change. You can also enter your address on the state's fire hazard severity zone map to see whether your property falls in a zone.
Can a sunroom be built on my existing deck?
Yes, a sunroom can go on a deck, but the deck will typically need added beams, posts or footings to carry the weight of the room. Plan on having a local structural engineer check whether your deck is suitable before the room is designed, so you know early what the deck needs.
Can I put a sunroom on my old concrete patio?
Sometimes, if the slab is in very good shape. One maker's installation guide prefers a new slab or deck and says an existing one needs to be in "like new" condition, because a slab with numerous buckles or cracks is unsuitable and could lead to leaks later. I look at your patio closely at the estimate and tell you plainly whether it will carry a room.
How do I keep a sunroom cool in the summer?
Block the sunlight before it reaches the glass, usually with shading on the outside of the room. East and west walls are harder because the sun sits low on them, so rooms facing those ways may need more than outside shading alone. The roof matters too, since on a midsummer day a square foot of roof can take in about three to four times as much sun as a square foot of north- or south-facing wall, so ask any builder how their roof handles summer sun.
What is the best way to decide between a sunroom with its own heating and cooling and one that joins the house?
Start with how your family will use the room through the year. A sunroom with its own heating or cooling keeps your home's existing doors and windows in place, so it stays separate from the rest of the house, while a room that joins the house is built much like a regular room addition. I'll ask how you plan to use the space before I recommend either one.
