Apex Homes' Los Angeles County service area covers the unincorporated communities outside city limits, places where zoning, lot sizes, and local demand vary more than almost anywhere else Apex builds. What holds true across nearly all of them is the same underlying pressure: LA County's housing shortage means a legal second unit rents fast, wherever it sits.
No new mortgage, no new school district, no goodbye to the community you already know. Just more space, right where you are.
No bidding wars, no move-in surprises, no guessing what a new house actually needs. Just a fixed price, on the property you already own.
Parents, grown kids, or whoever needs it get their own front door and their own space, close enough to see every day.
One team handles the entire process under one roof, so you don't have to coordinate a separate architect, permit expediter, and contractor with the County of Los Angeles yourself.
We manage every step of design, permitting, and construction, so you don't have to navigate the County of Los Angeles Department of Regional Planning on your own.
Apex Homes reviews your lot's zoning, setbacks, and utility hookups before any commitment.
Choose from Apex Homes' floor plans, or go fully custom to fit your parcel.

Book a Free ConsultationOne detached or attached ADU plus one Junior ADU per lot. Detached ADUs up to 1,200 sq ft; attached ADUs up to 50% of the primary dwelling's size; JADUs capped at 500 sq ft within the primary residence. Side and rear setbacks run 4 ft minimum; unit separation runs 6 ft for ADUs up to 800 sq ft (10 ft, or attachment required, above that). Height caps at 16 ft (18 ft within a half-mile of public transit). Front-yard placement is not permitted for detached ADUs. Your free feasibility study confirms exactly what applies to your parcel.
Up to eight detached ADUs permitted on qualifying multi-family lots, or attached ADUs equal to 25% of existing units, whichever is greater. Conversions of existing non-livable space are also permitted under the same setback and height rules.
Every year that yard sits unused is rent, equity, and space someone in your family could actually be using, and in LA County, rental demand rarely lets up.
LA County's housing shortage means a well-built two-bedroom ADU tends to rent quickly almost anywhere in the unincorporated county; your feasibility study can pull comps for your specific area.
In equity your property isn't capturing yet. A legal, permitted ADU is one of the few upgrades that adds this much value to a property in LA County.
Without it, aging parents, adult kids, or long-term guests are stuck choosing between crowding your home or moving out of the community altogether.
None of that has to stay true. Here's what changes once you build.
Every floor plan includes architectural drawings, structural engineering, and Title 24 compliance, adaptable to the wide range of parcel types found across unincorporated LA County.
Apex Homes builds ADUs across 20+ Silicon Valley and Southern California communities. Find your area below for local pricing, regulations, and permitting timelines.
"I'm usually stingy with five-star reviews, but Apex Homes absolutely rocks. From the first call, they treated my scattershot sketches like gold: polished the design, wrangled the permits so I never saw City Hall, and kept every penny transparent."
