Oak Hills homes on open desert lots
Oak Hills is an unincorporated community in the high desert next to Hesperia, so San Bernardino County handles planning and inspections here instead of a city hall. The houses sit spread out on bigger lots than you'll find in town, with a mix of newer custom homes and older ranch-style houses. A lot of them have a covered patio or a deck off the back that faces open ground and long views.
We're a sunroom contractor based in Adelanto, CA, and we take jobs in many of the cities around it, including Hesperia and Spring Valley Lake. Oak Hills jobs tend to run larger because there's room to build out, and the back of the house usually has nothing nearby to block the sun or the wind, so we plan the roof, glass and footing around full exposure.

Our services in Oak Hills, CA
- Patio enclosures
Plenty of Oak Hills homes already have a covered patio out back that bakes in July and sits empty in January. Our patio enclosures close that space in with glass or screen walls once we've checked that the roof and slab you have can carry them.
- Four season sunrooms
With open ground behind most houses here, a room has to hold heat on cold nights and keep it out on summer afternoons. We build four season rooms with insulated walls, roof and glass, and we settle how you'll heat and cool the room before anything gets ordered.
- Sunroom additions
The lot sizes here give a lot of owners room for a real addition off the back instead of a closed-in porch. We build it on its own foundation and tie it into your roof and walls so it reads as part of the house.
- Patio cover installation
Shade is often the first thing people ask for here, because the back of the house takes the full afternoon sun. We size and attach patio covers so they can be closed in later if you decide you want a room after all.
- Deck-to-sunroom conversion
Raised decks are common where a lot slopes away from the house, and closing one in asks it to carry walls, glass and a roof it wasn't built for. We check the posts, beams and footings first and add support where it's needed before any glass goes up.
- Sunroom remodeling
Older rooms around here often have single-pane glass or thin roof panels, which is why they feel like an oven in summer and a cold box in winter. We replace the glass, roof or walls so the room becomes one you'll actually sit in, keeping as much of the sound frame as we can.
What Oak Hills sun and cold ask of a room
Oak Hills sits in the rain shadow of the San Bernardino Mountains, so summers run hot and dry, and winters can bring freezing nights and the odd snowstorm. A glass room built without that in mind heats up fast in the afternoon and loses it all after dark. That's why I settle the glass, insulation and heating with you before anything is ordered, because changing them after the walls are up costs you more and stalls the job.
Price on most jobs here comes down to size, what the room sits on and how well it's built for that weather. A sound slab or deck saves work, while a new foundation adds cost and time, and the county permit review is the other thing the schedule turns on. I give you a figure for your own room at the estimate.

Sunroom and patio room ideas
Oak Hills sunroom questions answered
How do I get a permit for a sunroom in Oak Hills?
Because Oak Hills is unincorporated, permits come from San Bernardino County's Building and Safety office, and its list includes additions, alterations and patio covers, which covers most sunroom work. The permit has to be in hand before work starts, either from the office or through the county's EZ Online Permitting website, and your setbacks from the property lines have to be kept either way. We check with the office that covers your address and take care of the paperwork, and if you want to ask the county yourself, its desert-area line is (760) 995-8140.
Do I need a permit to replace windows in Oak Hills?
Yes, the county's guidance says every window and exterior door replacement needs a building permit, however the job is classified. That guidance is several years old, so when a remodel means swapping out glass, we confirm the current rule with the county before we order anything.
Can I build a small shed in Oak Hills without a permit?
Yes, if it's a one-story detached shed or playhouse of 120 square feet or less, with no utilities, under 14 feet tall and inside the required setbacks. A sunroom attached to your house doesn't fall under that, so it goes through the permit process above.
Does my sunroom contractor need a California state license?
Yes, the Contractors State License Board requires a license for any project that needs a building permit, uses extra workers or totals $1,000 or more in labor and materials, which takes in any sunroom. The contractor has to hold that license before giving you a bid. The county doesn't issue a countywide business license, so the state license is the one to ask about, and we're licensed and fully insured.
How much does a sunroom cost in Oak Hills?
The biggest thing that sets the cost is whether you want a three season room or a fully insulated four season room. The four season room needs insulated glass, a heavier roof and a way to heat and cool it, which is worth it if you plan to use the room on January nights. Closing in a patio you already have usually costs less than a new addition, because a sound roof and slab can stay.
What causes a sunroom to get too hot in the high desert?
Usually it's clear single-pane glass, an uninsulated roof and no way to let hot air out, all facing the afternoon sun. We fix that with insulated, coated glass, an insulated roof, windows that open and sometimes a cover over the west side. If your room already cooks every summer, call (760) 523-8749 or send us a request and I'll come take a look.
