About Lomita, CA
Lomita is a small, mostly residential city right next to Torrance, and it's a short drive for our crew from our base in Long Beach. Most of the calls we get here come from single-family homes on modest lots, with shops and small businesses along the main boulevards. A lot of these houses have been added onto over the years, usually with a patio slab out back, a wood patio cover or a room someone built a long time ago.
With backyards this size, the new room usually has to go where the patio already is, so the slab and the back wall it joins decide most of the plan.
Services in Lomita, CA
Enclosed patio rooms
Plenty of Lomita backyards already have a slab and a cover, and closing that space in is often the quickest way to get more room. We build enclosed patio rooms on the patio you have once I've checked that the slab and cover can carry walls and windows.
Patio-to-sunroom conversion
If you want a room you'll use every day and not just on nice afternoons, your patio can become a full sunroom with an insulated roof and real glass. We decide whether the slab stays or needs a new base before anything gets drawn, so the plan matches what we build.
Sunroom additions
On lots with no patio to start from, the room joins straight to the back wall of the house. We tie it into your roof line so it reads as part of the house and sheds water the way it should.
Patio cover installation
Afternoon sun on a bare slab can make a small backyard too hot to use for much of the summer. A patio cover gives you shade now, and we can build it so it's ready to enclose later if you decide you want a room.
Screen room installation
Some homeowners here want fresh air without the bugs and don't need a room they can heat. A screen room keeps the build simpler and the cost lower, and it still gives you an outdoor space you'll actually sit in.
Sunroom remodeling
Older houses here sometimes come with a sunroom added years ago, with leaky glass, a tired roof or a floor that's settled. We replace what's failing and keep what's still sound, so you aren't paying to rebuild the whole room.
Working in Lomita: the county check and what sets your price
An earlier city report says Lomita contracts with Los Angeles County for its building and safety work, so county staff check the plans and inspect permitted work on the city's behalf. That county plan review is a big part of the schedule for a room that needs a permit, along with how quickly the design gets settled and when materials arrive, so we pull the permit and handle the paperwork as soon as the plan is final. We're fully licensed and insured. Your price moves mostly with the size of the room, whether your slab can carry it or we pour a new base, and whether you want year-round glass or screens, and the written estimate puts your own number on those choices.
Most of our Lomita jobs sit on residential streets a few blocks off Pacific Coast Highway, Lomita Boulevard or Narbonne Avenue, where parking is tight and a delivery truck can't always pull up to the house. I plan where materials get dropped and where the crew parks before the build starts, so your neighbors' driveways stay clear. We do the same work nearby in Carson and across the other cities around Long Beach.
Lomita, CA properties and local conditions
A lot of the patios we see in Lomita were poured to hold chairs and a grill, not walls and a roof, and the wood covers over them have often been through many summers of sun. Before we talk about glass or roof panels, I look at how thick the slab is, whether it's cracked or out of level, and whether the cover has rot where it meets the house. If the base is good, we build on it, and if it isn't, I tell you at the first visit so the plan and the price account for it from the start.
The city's own general findings cite heavy winter rains that often lead to expansive soil, which swells and shrinks with moisture and can lift or crack a slab. Those findings speak to Lomita as a whole, so I check your actual ground and base on site instead of guessing.

Frequently asked questions
How much does a sunroom cost in Lomita?
You get a written price after a free visit, because a Lomita sunroom's cost turns on things I need to see in person. The biggest swings are the room's size, whether your slab can carry it or needs a new base, insulated glass for year-round use versus screens or single panes, how the roof ties into the house, and whether you want lights, outlets or a ceiling fan. A screen room or an enclosed patio on a sound slab usually costs less than a full addition off the back wall.
Which building codes apply to a sunroom in Lomita?
Lomita uses Los Angeles County's building codes, adopted by reference so the county codes become the city's own rules. An earlier city report says the city takes up the county's updated codes every three years, and it describes a proposed ordinance that would adopt the latest county codes with some local amendments. That means the rules your room is checked against follow the county's updates, and we draw the plans to the code the county reviewers are using at the time.
How do Santa Ana winds affect a sunroom in Lomita?
Wind and heat are the two things a glass room here has to handle, and the city's general findings describe hot, dry summers followed by strong Santa Ana winds. Those findings sit in a proposed code ordinance and cover the whole city, not your yard in particular. At the visit I look at how exposed your backyard is and how the room will fasten to the house, and we plan the roof and glass around that.
How long does it take to add a sunroom in Lomita?
Most of the wait usually comes before the build starts, while the design is settled and, when the job needs a permit, while county staff review the plans. A room built on a sound existing slab moves faster than one that needs a new base first. I'll tell you at the estimate which parts of your job set the schedule.
What is the best way to turn a patio into a sunroom in Lomita?
Start with the slab and the wall it joins, because those decide whether enclosing the patio makes sense or a full sunroom is the better buy. If the slab is sound and the cover is solid, an enclosed patio room is usually the simpler path. If the slab is cracked or too thin, I'd put that money into a proper base and a sunroom that will hold up.
Where can I see drought-tolerant plants to put around a new sunroom in Lomita?
The city's Demonstration Garden, just southeast of Lomita City Hall next to the parking lot, shows drought-tolerant plants and efficient irrigation, with signs naming each plant. The city says the redesign cut the garden's water use by over 70%. We build the room, not the garden, but a new sunroom often leaves a strip of yard to replant, and it's a good place to get ideas first.
