Homes and lots across Joshua Tree
Joshua Tree is an unincorporated community in the High Desert at about 2,700 feet, with houses spread out across roomy lots. We're based just up the road in Yucca Valley and build out toward Twentynine Palms too, so these homes are familiar ground for us. What we usually find is a mix of older homes and newer builds, many with a slab patio, a wood deck or an add-on room that somebody put up years ago.
Those older slabs and add-ons are why I spend extra time on the first visit. A room is only as good as what's under it and where it ties into the house, and on a lot of homes here both need a closer look before anyone can price the job honestly.
Building in Joshua Tree means working with the county
Joshua Tree has no city hall because it's unincorporated, so your sunroom permit comes from San Bernardino County's Building and Safety Division, which issues permits for additions and alterations. That puts the county's permit approval and inspections on your schedule, along with however much work your base needs. The county doesn't issue a general business license for contractors in unincorporated areas, so the license worth checking is the contractor's California state license, and only a property owner, a state-licensed contractor or an agent for either can pull the permit. We're licensed and insured, and when your job needs a permit we prepare the paperwork, sign the license statement the county requires, book the appointment and meet the inspector on site.
Price here mostly comes down to what the room sits on and how it meets your house, then the size and whether you want a screen room, a patio cover or a full glass room. An old slab that needs work, a deck with tired footings or a roof line that's awkward to tie into all add cost, and I'd rather find that on the first visit than halfway through the build. Some homes here sit down long dirt roads, so we sort out deliveries and access before we start. Your free written estimate lays out the price, and we work with whichever office covers your address, whether that's the county here or the office for a job over in Desert Hot Springs.

Four season sunrooms
A lot of Joshua Tree owners want a room off the back of the house they can use every month of the year, and four season sunrooms are built as real rooms with insulated walls and glass for exactly that. We set them on a base we've checked and take our time on the joint with the house, because that seam is where most leaks start.
Patio-to-sunroom conversion
Many homes here already have a concrete patio out back, and turning it into a sunroom makes sense when the slab is sound. I check it for cracks, settling and which way it drains before we put walls and a roof on it.
Deck-to-sunroom conversion
Older wood decks around here often look fine on top and tell a different story underneath. We look at the posts, beams and footings, and fix or replace whatever can't carry the weight of a room.
Screen room installation
If you mostly want to sit outside without the bugs, a screen room is usually the simpler and cheaper choice, and I'll tell you so. We frame it to fit your slab or deck and the wall it meets.
Patio cover installation
Some lots here have a bare slab off the back door that only needs a roof over it. We build patio covers that tie into the house at the right height and pitch so runoff heads away from the wall.
Sunroom remodeling
Plenty of add-on rooms in Joshua Tree were built years ago and now leak at the roof line or feel drafty. We find where the water's getting in, usually where the room meets the house, and rebuild that part instead of patching it one more time.
How it goes when you call us about a Joshua Tree sunroom
Call or send a message
You call (760) 418-0263 or fill out the form, and we get back to you to set a time for me to come out. It helps if you're home for the visit so we can talk through the room together.
I measure and look underneath
I measure, look hard at the slab or deck and where the room will meet your house, and ask how you plan to use it. Then you get a free written estimate, so you see the cost before you decide anything.
We handle permit and build
We take care of the county paperwork and meet the inspector, and because the county has fewer weekday inspection days in some remote areas, the open days for your address can set the pace. Our own crew builds the room, and I check in at the key steps.
Walk the finished room together
When the room is done, I walk it with you and go over how it meets the house and what we did underneath. Satisfaction guaranteed.
Common questions
Do I need a permit to add a sunroom in Joshua Tree, CA?
Usually yes, because a sunroom joined to your house counts as an addition, and San Bernardino County issues permits for additions and alterations. For a screen room or patio cover, the county notes that work beyond its list may still need a permit, so ask before anything gets built. The county's desert-area permit line is (760) 995-8140, and if you hire us, we make that call and handle the paperwork.
How do I know if a sunroom contractor needs a California license?
Anyone you pay to build a sunroom should hold a California contractor license, because the state's exemption for unlicensed minor work is small and narrow. It went from $500 to $1,000 at the start of 2025, and it only applies when the job needs no permit and the person hires nobody to help. Ask for the state license number before you sign anything.
How much does a sunroom cost in Joshua Tree?
There's no single price, because the cost here comes down mostly to the base, the house wall, the type of room and its size. A screen room on a sound slab usually costs far less than a glass room that needs new footings and a tricky roof tie-in, and if a simpler room fits how you'll really use it, I'll say so. My free written estimate gives you your own number once I've seen the slab or deck.
How long does a San Bernardino County building permit stay valid?
A county permit expires if work doesn't start within 12 months of issuance, or if work stops for 12 months after it starts. The building official can grant a 180-day extension in writing, but only after a written request showing a good reason, as the county's building and safety FAQ explains. We schedule the build so your permit doesn't sit idle.
Is a sunroom covered by the county's no-permit rule for small sheds?
No, that rule is written for a detached one-story shed or playhouse up to 120 square feet, with no utilities, within setbacks and under 14 feet tall. A sunroom attaches to your house and usually has power run to it, so don't plan on that rule covering your room.
Do setback rules apply to a sunroom or patio cover in Joshua Tree?
Yes, the county says all building setbacks have to be kept, whether or not a building needs a permit. That matters when your patio already sits close to a property line, because the room can't always grow to the edge of the slab. I check where the room can go on the first visit.
