Quick answer: APLA Construction is a licensed California general contractor (CA Lic #1136359) working throughout Orange County — ADUs, room additions, kitchen and bathroom remodels, HVAC, and ground-up construction. Room additions run $125–$350 per sq ft and detached ADUs $200–$400 per sq ft. Free on-site estimate: (818) 818-4419.
APLA Construction Group Inc. builds across Los Angeles, Ventura and Orange counties. In Orange County we take on the same work we are known for in Los Angeles: accessory dwelling units, room additions, kitchen and bathroom remodels, HVAC installation and replacement, and new residential construction. Cities served include Irvine, Anaheim, Huntington Beach, Newport Beach, Santa Ana, Costa Mesa, Fullerton, Orange, Tustin and Laguna Beach.
A California contractor’s license is a statewide license — there is no separate Orange County license to hold. What actually changes from city to city is the permit path, and that is where a contractor who does not work here regularly loses your time.
Orange County is the most jurisdictionally fragmented market APLA works in. Three things shape a project here:
ADU entitlement is state law, so the rules are the same ones APLA applies daily in Los Angeles: an ADU with 750 sq ft or less of interior livable space is exempt from impact fees, and replacement parking cannot be required when a garage or carport is converted or demolished to build one (California HCD ADU Handbook). The practical difference in Orange County is the HOA layer and, on coastal parcels, the Coastal Development Permit — neither of which can block a compliant ADU outright, but both of which need to be started early rather than discovered late.
| Project | APLA Pricing |
| Room addition (single story) | $125–$350 per sq ft |
| Detached ADU (new construction) | $200–$400 per sq ft |
| New home, ground up | $250–$700 per sq ft |
| Kitchen remodel | $10,000–$100,000 depending on cabinetry and countertop material |
These are APLA’s own working ranges, not scraped industry averages. Where a project lands inside them is driven mostly by cabinetry and stone selection on interiors, and by site conditions — slope, soil, utility distance — on ground-up work.
Your project is reviewed either by the OC Development Services, Building and Safety (official site) if your parcel is unincorporated, or by your own city’s building department if it is not. APLA prepares and submits the permit package either way, and coordinates plan-check corrections through to approval. We will tell you which authority governs your address at the site walk, before any drawings are commissioned — getting that wrong is expensive to unwind.
Yes. APLA is a licensed California general contractor (CA Lic #1136359) working across Los Angeles, Ventura and Orange counties. A California license is valid statewide; what varies is each city’s building department process, which we manage as part of the project.
No. California law prohibits an HOA from banning an ADU outright. What an HOA can do is review and regulate exterior design, materials and colors — and that review runs on its own timeline alongside the city’s plan check. We start HOA submittal early rather than treating it as an afterthought, because it is the most common source of avoidable delay in a master-planned community.
Possibly. Parcels within the Coastal Zone can require a Coastal Development Permit in addition to the standard building permit, issued either by the local jurisdiction under a certified Local Coastal Program or by the California Coastal Commission. Whether your specific parcel is affected is one of the first things we verify.
We work throughout the county — Irvine, Anaheim, Huntington Beach, Newport Beach, Santa Ana, Costa Mesa, Fullerton, Orange, Tustin and Laguna Beach. Call (818) 818-4419 to confirm scheduling for your address.
APLA self-performs electrical, HVAC, cabinetry, flooring, and paint, and manages the remaining trades directly rather than handing your project to a broker. On ADU work specifically, APLA handles the project end to end. That matters more in Orange County than it does close to our Valley base: when the crew doing the work is the crew we employ, a longer drive doesn’t turn into a slower job or a chain of finger-pointing between subs.
