West Whittier-Los Nietos: county ground, lived-in homes
West Whittier-Los Nietos sits just west of our home city, running toward Santa Fe Springs, and it isn't a city at all. It's an unincorporated community, so Los Angeles County serves it instead of a city hall. Most of it is houses on regular residential streets, with shops and services out along the bigger roads, and most of those houses are lived in by the people who own them. That matters to me, because an owner who plans to stay usually wants a room built to last, not a quick cover-up.
Behind a lot of these homes we find the same setup: a concrete slab off the back door, often with a patio cover that's been there for years. That slab and the spot where any new roof meets the house are where these jobs are won or lost, so we look hard at both before we talk about glass or roof panels.

Sunroom work we do in West Whittier-Los Nietos
Patio-to-sunroom conversion
Turning that back slab into a real room is the call we get most from this side of Whittier. Before we quote a patio-to-sunroom conversion, we check whether the slab can carry walls and a roof, because a patio slab often wasn't poured with that in mind.
Patio enclosures
Plenty of homes here have an older patio cover that still stands but lets in dust, leaves and cold air. We can enclose the space under it when the posts and beam are sound, and we'll tell you plainly when they need replacing first.
Screen room installation
If you mostly want the yard in the evening without the bugs, a screen room is the lighter, simpler choice. We set it on your existing slab when it's level and solid, so you get the airflow without paying for a fully closed room.
Patio cover installation
Some homeowners here want shade over a bare slab before they decide on walls. We plan the posts and footings around whether you might enclose it later, so that choice stays open.
Four season sunrooms
A four season room is meant to be used like any other room in the house, which means insulated walls, roof and glass. It's the biggest single choice on these jobs, so I'll walk you through where the extra cost goes before you pick it over a three season room.
Sunroom remodeling
Older add-on rooms turn up behind a fair number of houses here, and the usual trouble is a leak where the roof meets the house wall. We find out why it's leaking before we touch the panels, because new glass on a bad connection just leaks again.
Building in West Whittier-Los Nietos: what the county side means
Because West Whittier-Los Nietos is unincorporated, building permits here come from Los Angeles County Public Works, and a sunroom or enclosure is the kind of addition or alteration the county permits. A lot of homes around here carry a Whittier mailing address, so we check yours early to be sure who has the job, then we handle the paperwork and meet the inspector for each visit. The county's review and inspections set much of the schedule, and I'll keep you posted on where things stand. Before you hire anyone, us included, look up their license with the state licensing board. We're licensed and insured, and you should expect that from whoever builds your room.
When I come out to measure, the written estimate shows what actually sets your price: the size of the room, whether your slab can carry it or needs new footings, the step from a screen room to a three season room to a four season room, and how much electrical work goes in. It's the same way we work in Pico Rivera and back home in Whittier. The county paperwork is the part that makes this side different.

Sunroom ideas for West Whittier-Los Nietos
Sunroom questions from West Whittier-Los Nietos
How much does a sunroom cost in West Whittier-Los Nietos?
The price comes down to the room's size, how closed-in it is and what your slab needs, so I can't give you an honest number until I've measured. A screen room on a sound slab sits at the low end, and a four season room with insulated glass, new footings and added circuits sits at the high end. The free on-site estimate puts your figure in writing.
How do I tell if my patio slab can hold a sunroom?
You usually can't tell for sure by looking, but cracks that are wider at one end, edges that have sunk or a slab that slopes toward the house are all warning signs. A slab poured for a patio wasn't always built to carry walls and a roof, so I check its edges and condition on the visit and tell you whether it needs new footings before anything else.
When does a contractor need a CSLB license in California?
The California Contractors State License Board says a license applies when the project needs a building permit, uses employee labor, or costs $1,000 or more. That $1,000 counts labor and materials together, even when the work is split across more than one contract. For a sunroom, expect your builder to hold one.
How long do I have to get the first inspection after a county permit is issued?
The county says the first inspection is requested within 12 months of the permit being issued. After that, follow-up inspections are scheduled every 6 months to keep the permit active. We request those inspections and meet the inspector, so the permit doesn't lapse while your room goes up.
Do I need a permit to replace the windows or roof on my old sunroom?
Very possibly, because replacing windows and fixing a roof are both on the county's list of work it issues permits for. What your job needs depends on what we're actually changing, so we sort that out with the county before work starts and handle the paperwork.
Do I need a permit for a portable heater or AC unit in my sunroom in Los Angeles County?
No, the county requires no mechanical permit for a portable heating appliance, portable ventilating equipment or a portable cooling unit. A new circuit or a wall-mounted unit is a different story, because separate electrical or mechanical permits may still be required. Tell me how you plan to heat or cool the room, and we'll plan the wiring for it from the start.
