Older houses and backyard rooms across Pomona
Pomona has a lot of housing ages side by side. Near downtown you'll find older houses on narrow lots, and the city has several historic districts and landmark properties, while up around Phillips Ranch the tracts are newer, often with sloped yards and a deck off the back. Most of the calls we get here start with a slab out back, an old patio cover or a deck the family already uses and wants to close in.
We do the same work in West Covina and the other cities between here and Baldwin Park, but Pomona's mix shapes the job early. On an older house the new roof has to meet a wall and eave that are rarely perfectly square, so I measure more than once. On a newer hillside lot, the first question is usually what the deck or slab is really sitting on.
Permits, plans and pricing for a Pomona sunroom
In Pomona, building permits come from the city's Building Safety Division, which also reviews plans and does inspections, so when your room needs a permit, that review and those inspections set part of the schedule. Before anything is drawn up, I check whether your address goes through the city or Los Angeles County, because it isn't the same everywhere we work, and some addresses, like ones in East Los Angeles, go through the county instead. When the job calls for a permit, we take care of the paperwork. We're licensed and insured, and the city is also where a local business license application starts, which is something you can ask any contractor about.
The price moves with the size of the room, the type you pick, from a screen room to a fully enclosed four season room, the glass and roof, whether it opens into the house, and how much work the slab or deck needs before a room can sit on it. The schedule turns on the permit step and on ordering, because nothing gets ordered until the measurements and the base check are done. You get your own figure in a written estimate after I've been out to look.

Patio-to-sunroom conversion
A lot of Pomona backyards already have a concrete slab off the back door, and that's where most of our rooms start. I check it for level, cracks and what's under the edges before we plan walls on it, because a room is only as square as what it sits on.
Patio enclosures
Plenty of houses here have an older patio cover the family already treats like an outdoor room. We check whether the posts and roof can carry walls and windows, then close it in where they can and tell you plainly where they can't.
Custom sunrooms
Older Pomona houses rarely have walls and rooflines that match a stock kit, so custom sunrooms are often the better fit here. We size the room to your house from my own measurements, so it lines up with the eave and the wall it joins.
Deck-to-sunroom conversion
Newer houses on sloped lots often have a raised deck instead of a slab. Before a room goes on top, I look at the framing and footings underneath, since a deck built for chairs and a grill wasn't necessarily built to carry walls and a roof.
Four season sunrooms
When a family wants the room to work as part of the house, opening right off the kitchen or living room, a four season room is usually the choice. We talk through the glass and how the room ties into your wall, so the edges stay sealed where old meets new.
Sunroom remodeling
Some Pomona houses already have a sunroom or enclosed porch added years ago, often with worn seals and tired glass. We look at what's worth keeping first, then replace the panels, glass or roof that need it so the room gets used again.

Common questions
Who issues building permits for a sunroom in Pomona, CA?
The City of Pomona's Building Safety Division issues building permits in Pomona. The same office reviews construction plans and does inspections, so if your sunroom needs a permit, that's where the plans go. We take care of that paperwork when the job calls for it.
Do I need a permit to enclose my patio or add a sunroom in Pomona?
Check with the city before you build, because Pomona's list of work exempt from a permit names things like fences up to 7 feet and low walls, not rooms added to a house. The city's Do I need a Permit? guidance is a good place to start reading. When I come out, I check what the city asks for at your address, and we handle the permit if your job needs one.
When can I visit Pomona Building and Safety in person?
Building and Safety takes walk-ins Monday through Thursday, 7:30 a.m. to 6 p.m., at City Hall, 505 South Garey Avenue. You can also call the division at 909-620-2371. If we're handling your permit, you don't need to make the trip yourself.
How much does it cost to add a sunroom to an older house in Pomona?
Your own figure comes from a free written estimate after I've measured and checked the base, because two rooms the same size can price very differently. On older Pomona houses, the extra cost usually shows up where the new roof ties into an old wall that isn't square, and in any slab or deck work needed first. Beyond that, the room type, glass and size set most of the price.
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 anything is ordered. I look for cracks, low spots and settling, and at what's under the edges where the walls will sit, because the frame has to land on something solid and level. If the slab needs work, you'll hear it in the estimate, before you've spent anything on the room.
How long does a sunroom project take in Pomona?
A lot of the timeline usually depends on what happens before the build, mainly the permit step and ordering parts. If the room needs a permit, the city reviews the plans and inspects the work, and nothing gets ordered until I've measured and checked the base. I'll tell you what to expect for your room when I bring the estimate.
