Patio-to-sunroom conversion
A lot of houses here already have a back patio slab, and closing it in is usually the shortest path to a new room. We check that slab first, then frame, glaze and roof it so it reads like part of the house.
All season rooms
If you want a room you'll use in July and in January, an all season room with insulated glass and a solid roof is the one to look at. We size the glass and roof panels for the way the sun hits your yard so the room doesn't bake on a hot afternoon.
Patio cover installation
Plenty of backyards here get full sun on the patio and need shade more than walls. We put up covers that tie cleanly into the house, and they can be closed in later if you change your mind.
Sunroom remodeling
Older add-on rooms we see here tend to leak at the roof joint, run hot or feel like a porch with windows stuck on. We find out why it isn't working and fix the part that's causing it, so you're not paying to start over.
Screen room installation
If you mostly want evenings outside without the bugs, a screen room is a lighter build and easier on an older slab. We can set the frame up so glass panels can go in later.
Sunroom additions
When there's no patio worth building on, we build the room from new footings up as a true addition to the house. That's the route when you want the room built like the rest of your house, not like a patio with a roof.
South San Jose Hills, CA properties and local conditions
Most houses in South San Jose Hills are single-family homes from the middle of the last century, and plenty of them have a back patio slab poured long before anybody thought of putting a glass room on it. A slab that age may be thin, cracked or tilted toward the house, and a sunroom is mostly glass resting on whatever is under it, so I look at the slab or deck before anyone talks about glass. Sometimes it can carry the room as it is and sometimes it needs new footings at the edges, and I'd rather find that out now than after the windows start sticking.
Rain doesn't come often here, which is how a bad roof joint can hide for years until the first real winter storm finds it. We flash and seal the spot where the new roof meets your house and slope the roof so water runs off it, not into your wall.
What we know about building sunrooms in South San Jose Hills
South San Jose Hills isn't a city of its own. It's unincorporated Los Angeles County, so LA County Public Works is the office that issues permits here for additions, alterations and new electrical work, and its inspections set part of the schedule. When your job needs a permit, we take care of the paperwork and work through the inspections with you. The license to check on any contractor is the state one, because the California Contractors State License Board licenses anyone building or altering a structure when the job needs a building permit, uses employees or costs $1,000 or more in labor and materials, and splitting a big job into smaller bills doesn't get around that. We're licensed and fully insured. A County Business License only applies when a business's work is on the county's list, so not every contractor here will carry one. What moves your price is the room's size, what it sits on, three season or four season, and the glass, roof and wiring you pick, and your written estimate gives you the number for your house.
The community borders West Covina on the north and east, with La Puente to the west and Industry to the west and south, so two houses a short walk apart can answer to different permit offices, and we check every address before we plan anything. We're based in Hacienda Heights and build in a lot of the cities around it, including Valinda, where the houses look a lot like the ones here.

Frequently asked questions
How do I know if my South San Jose Hills address is in unincorporated LA County?
Look up the street address, not the zip code, because more than 60 zip codes in the county cross county and city lines. On the county's Service Locator, enter your street address or your parcel number using numbers only, click Find Services, and it shows which office gives permits for that address. We run the same check before we draw anything.
Do I need a separate electrical permit for a sunroom in South San Jose Hills?
You might, because the county says separate plumbing, electrical and mechanical permits may still be required unless the work is exempt. A portable heating or cooling unit needs no mechanical permit, but wiring for lights, outlets or a ceiling fan is installing electrical work, and the room also has to meet local zoning. You can read the county's list of exempt work, and we work out what your room needs before building starts.
How long do I have to get a sunroom permit inspected in South San Jose Hills?
The first inspection should be requested within 12 months of getting the permit, and after that, inspections every 6 months keep the permit active. That mostly matters if a job stalls partway. We work through the inspections with you so the permit doesn't lapse.
How much does a sunroom cost in South San Jose Hills?
The price comes down mostly to what the room sits on, how big it is and how much glass and insulation it needs, and on the older patios here the slab is usually the biggest swing. A slab that's ready to build on keeps the cost down, while new footings, insulated glass and new wiring push it up. I'll give you a written estimate for your house after I've seen it.
What is the best way to add a sunroom to a mid-century house in South San Jose Hills?
Build it to fit the house you have, starting with the roofline, because a lot of these houses have low eaves that limit how high and how steep a sunroom roof can go. We usually work the new roof under or onto the old one so the ceiling height feels right and water has a clear path off. Matching the stucco and trim helps the room look like it was always there.
Should I get a three season or four season sunroom in South San Jose Hills?
Go four season if you want to sit in it on summer afternoons, because insulated glass and an insulated roof are what keep the heat out here, more than the cold. A three season room costs less and works fine for mornings, evenings and our mild winters, but plan on it running hot in July. I'll ask when you'll actually use the room, and that usually settles it.
About South San Jose Hills, CA
South San Jose Hills is mostly quiet single-family streets, close in to La Puente and West Covina, with very little commercial mixed in. On our jobs here we see a lot of back patios, older patio covers and the occasional add-on room from decades past, and the calls are usually about getting more use out of one of those or fixing a room that never worked right.
The lots are already built out, so a sunroom here almost always goes where the patio already is. That's why what's under it, and how the new roof meets an older house, shapes nearly every job we do in this community.
