About Bloomington, CA
Bloomington is the largest and most developed unincorporated community in San Bernardino County, so there's no city government here and the county handles things. It's a short drive for us from Colton, the same as Loma Linda, and the calls we get here sound like the ones we get everywhere else. People have a patio, a deck or an older room that isn't pulling its weight, and they want more use out of it.
What changes from one Bloomington job to the next is the house and the lot it sits on, so I don't show up with a one-size plan.
Services in Bloomington, CA
Patio-to-sunroom conversion
A lot of the subdivision homes here have a concrete patio out back that gets used a few times a year. A patio-to-sunroom conversion starts with checking whether that slab can carry walls and a roof, and if it can't, we tell you before anything gets built on it.
Sunroom additions
On the bigger lots there's room to add on, and it's easy to talk yourself into more room than you'll use. We size the addition around how you'll really live in it and tie it into the house so it looks like it belongs.
Patio cover installation
Plenty of folks on larger properties want a covered spot to sit outside without closing it in. We set the cover where it makes sense for the yard and attach it to the house or stand it on its own posts, depending on the layout.
Deck-to-sunroom conversion
Homes with a raised wood deck often want it enclosed, but a deck built for chairs wasn't built to hold walls. We check the framing and footings first and beef them up where the room needs it.
Four season sunrooms
When a family wants a real room they'll use every month, like an office or a place for the kids, a four season room is the one we steer toward. It gets insulated glass and walls and is built to be part of the house, not a porch with windows.
Sunroom remodeling
Older rooms here tend to show their age at the roof panels, the seals and the spot where they meet the house. We fix what can be fixed and rework what can't, so you're not paying to tear out a room that only needs part of it redone.
Building in Bloomington means working with the county
Because Bloomington is unincorporated, a sunroom permit comes from San Bernardino County's Building and Safety office instead of a city hall, and the time the county takes with it sets the pace before any building starts. When you're checking out a contractor, the license that matters is the state contractor license. There's no city business license to ask about here, because the county's Clerk of the Board doesn't issue business licenses in the unincorporated area.
We take care of the plans, the county paperwork and the inspections, and we're licensed and insured. The price moves with the room's size, whether it's a three season or four season room, and what the slab or deck needs before it can carry walls, while the schedule turns mostly on the permit and that prep work. Your written estimate puts a figure on your own job. We do the same work nearby in Rialto and Fontana.
Bloomington, CA properties and local conditions
Houses in Bloomington run from large-lot rural estate homes to newer subdivisions, with some apartments and several mobile home parks in between. On a tract home the room usually goes over the back patio between narrow side yards, so the lot and the roofline set its size. On a big rural lot the question is more where the room should sit and how it ties into the house, and on a mobile home the way a room attaches is different enough that I look closely before I tell you what's possible.
A lot of the patio covers and rooms we look at here went up years ago, sometimes by an owner before you. The trouble usually starts where they fasten to the house, so that's the first place I check, and it often decides whether we repair or rebuild.

Frequently asked questions
How do I get a permit for a sunroom in Bloomington, CA?
You usually don't have to do it yourself, because we prepare the plans, file the paperwork and set up the inspections. Plan on needing one, since the county's permit list includes new structures over 120 square feet and the county wants permits in hand before work starts. A smaller room or cover isn't automatically off the hook, because the county says other work can need a permit too, so we confirm it for your address.
Do I need a permit to replace sunroom windows in Bloomington?
Yes, the county requires a building permit for every window and exterior door replacement, no matter how the job is classified. That catches people who are redoing an older room, so when a remodel means swapping glass panels or a door, we build the permit into the plan from the start.
What building code does a sunroom in Bloomington have to meet?
It has to meet California's building standards along with San Bernardino County's own amendments, which the county's Building and Safety staff enforce. The room also has to keep the setbacks, the required distance from your property lines. On a tight tract lot that can decide how far the room reaches toward the fence.
When does a sunroom contractor need a California license?
A contractor needs a license from the Contractors State License Board when the job needs a building permit, uses any helpers, or totals $1,000 or more in labor and materials across its contracts. Almost any sunroom job meets at least one of those, so ask whoever you're talking to for their license. We're licensed and insured.
How much does a sunroom cost in Bloomington, CA?
The price comes from the room you pick and what your house needs to hold it, and you'll get your own figure in writing after I've seen the spot. A four season room with insulated glass and power costs more than a three season room, so I'd only point you to one if you'll use it as a full-time room. A slab that needs work, a deck that needs new framing and a bigger footprint all add to it too.
How do I turn my patio into a sunroom in Bloomington?
Start by having the slab and the wall it meets looked at, because the room's walls sit on that patio and its roof ties into your house. If the slab is in good shape we build on it, and if it isn't, we tell you what it needs before you commit. From there we draw the plans, take care of the county permit and build the room.
