Patio-to-sunroom conversion
A lot of East LA backyards already have a concrete patio right off the kitchen, and that's usually the easiest place to put a room. We check the slab first, then build walls and a roof on it if it can carry them, or add footings if it can't.
Custom sunrooms
Lots here are narrow, and the space behind the house rarely comes in a standard size. Our custom sunrooms are drawn to your actual footprint, so the room fits the yard instead of swallowing it.
Patio cover installation
Plenty of homeowners here want shade over the patio without walls, at least for now. We can set the posts and beams so walls could go on later if you change your mind.
Sunroom remodeling
Older houses here sometimes came with a back room that someone enclosed years ago and that never quite worked, because it leaks, it's drafty or it sags at the roof line. We find out what's wrong underneath and where the roof meets the house before we touch the glass, because new windows on a bad base just leak in a newer way.
Screen room installation
If you mostly want the patio usable in the evening without the bugs, a screen room is the lighter, simpler choice. It's lighter on the slab too, which matters when the patio behind an older house was poured thin.
Four season sunrooms
When the back room is going to be an office, a playroom or a place for family to stay over, it needs insulated walls, an insulated roof and real electrical. On an older house that often means checking the electrical panel and tying the roof in carefully, and we plan for both from the first visit.
East Los Angeles, CA properties and local conditions
Many of the houses we see here are older, set close together, with a back patio that was poured a long time ago. That slab was built for a grill and some lawn chairs, not a roof and a wall of glass. A sunroom is mostly glass resting on whatever is under it, so we look at the slab or deck before we design anything, and if it needs new footings, you hear that before you hear a price.
Lots are tight, and side yards can be narrow enough that you turn sideways to get through. We plan how panels get from the street to the backyard, and sometimes that means carrying glass through a side gate by hand. I've been doing that since before I could drive, so it doesn't slow us down much.
Building in East Los Angeles: the County runs the permit side
East Los Angeles is unincorporated, so your permit comes from the County, not a city hall. LA County Public Works issues permits here for additions and alterations and runs a Building and Safety Office in East Los Angeles, so the permit comes first and the building comes after it. Before you hire anyone, ask for their California contractor's license, since the state says a contractor has to be licensed before they even bid. A business located in an unincorporated County area also needs a County Business License when its line of work is one the County licenses. We're licensed and fully insured.
We look up which office handles your address, and when the job needs a permit, we do the paperwork and work through the inspections with you. Price moves mostly with the size of the room, how finished it is, from screen walls up to a fully insulated room, and what the slab or deck under it needs. The schedule turns on the permit and on what we find underneath. You get your own number in a written estimate after I've seen the house. We build in Norwalk and El Monte too, and the first thing I check there is who handles the permit, because it isn't always the same office.

I look, measure and ask
I come out to check what the room will sit on, measure, and ask how you plan to use it, so it helps if you're home. Then you get a written estimate, so you know what you're getting into before you sign anything.
We sort out the permit
When the application goes in, the County's office says whether the drawings need a plan check, which is a review before approval, and what it takes to get them approved. That review usually decides when we can start.
We build, then walk through
My crew and I build the room and work through the inspections with you as we go. When it's finished, I walk through it with you before we call it done.
Frequently asked questions
Do I need a permit to add a sunroom in East Los Angeles?
Usually, yes. A sunroom attached to your house is an addition, and additions are on the County's permit list, along with patios and decks. Work that doesn't need a permit still has to meet the building code and any approvals other agencies require, so we check the details for your address before we build.
How long does a County building permit stay active in East Los Angeles?
You need to request the first inspection within 12 months of getting the permit, then schedule a follow-up inspection every 6 months to keep the permit active. We schedule inspections as the work reaches each stage and go through them with you, so the permit isn't left sitting.
Does a sunroom contractor in East Los Angeles need a California license?
Yes. The Contractors State License Board licenses anyone who builds or alters structures in California, and a license applies when a project needs a building permit, uses any additional workers, or totals $1,000 or more in labor and materials. A sunroom usually checks all three boxes, so ask for the license before you take a bid seriously.
What makes a sunroom cost more or less in East Los Angeles?
The size of the room, the kind of room and what's underneath it move the price most. A screen room costs less than a fully insulated room with power and lights, and an old slab that needs repair or new footings adds cost, as does tearing out an old patio cover or tying a new roof into an older house. Your number comes from the written estimate after I've seen the house.
How do I know if my patio slab can hold a sunroom?
You usually can't tell by looking, which is why I check it before we talk price. I look at cracks, settling, how thick the edge is and whether it slopes away from the house, and sometimes the honest answer is new footings around the edge. A slab that's fine for a screen room can still be wrong for a heavy glass room.
Do the East Los Angeles community plans affect a sunroom addition?
It depends on your address, so we check. LA County Planning keeps an East Los Angeles Community Plan, a Community Standards District and a specific plan for 3rd Street, and when I look up the permit side for your house, I look at whether one of them covers your lot too.
About East Los Angeles, CA
Whittier Boulevard runs along the south end of East Los Angeles, and a lot of people here call it the heart of the community, vendors and all. The County Hall and the East Los Angeles Library share the Civic Center by Belvedere Park, which is a handy reminder that this is County ground with County rules. Away from the boulevard it's mostly blocks of older single-family houses close together, with small backyards that families use hard.
We see the same older patios in Whittier and the cities east toward home. In East LA, the job usually starts with what's already behind the house: a slab, a tired cover, a narrow gate. Get those right and the room goes up straight.
