If you own property in Villa Park, you already know it’s different from anywhere else in Orange County. Half-acre and full-acre lots, equestrian trails, mature oaks, and a quiet rural character make this one of the few places where a tiny home, ADU, or custom addition can truly stretch out. Tiny Home Builders California has built and remodeled homes across Villa Park’s estate-zoned properties, and we understand exactly what these lots allow, and what they require.

We work with a wide range of homeowners across Villa Park and the surrounding hill communities. Many of our clients own large, established properties in Villa Park Estates or along Wanda Road and want to add an ADU for aging parents or adult children. Others are equestrian property owners near Santiago Estates looking to place a tiny home on wheels without disturbing existing barns or paddocks.
We also serve growing families in Cannon Estates who’ve outgrown their kitchen and need a full remodel, and retirees near Serrano Heights downsizing into a park model home while renting out their main house. If you’re in North Tustin, Orange Park Acres, or the Anaheim Hills canyon communities and need a builder who understands hillside and septic considerations, we’re the right fit too.

We design and build fully custom tiny homes on wheels (THOWs), ideal for Villa Park's larger lots where a mobile, non-permanent structure makes sense for guest housing or rental income. Most builds run $60,000–$150,000 depending on size and finish level, and we handle DMV registration requirements for road-legal units.
Park model homes offer more square footage than a THOW while remaining classified for flexible placement. They're popular among Villa Park homeowners wanting a comfortable, semi-permanent secondary unit for family or long-term guests, typically ranging from $80,000–$180,000.
ADUs are our most requested service in Villa Park, thanks to California's by-right approval laws and the city's generous lot sizes. We design detached, attached, and garage-conversion ADUs, with most projects landing between $150,000 and $400,000 depending on size and site conditions.

Villa Park's Residential Estate (R-E) zoning means many lots are a half-acre to two-plus acres, far larger than typical Orange County parcels. This gives homeowners real flexibility for ADU placement, detached tiny homes, and additions that simply aren't possible on smaller suburban lots nearby.
Recent state laws (AB 68, AB 587, AB 671, SB 9) require cities to approve most ADUs by-right, cutting through red tape that used to slow projects down. We stay current on these laws so your Villa Park ADU moves through permitting as fast as possible.
Many older Villa Park properties, especially those bordering Anaheim Hills and canyon areas, rely on septic systems or sit on sloped terrain. We've seen firsthand how skipping a proper soil and septic evaluation early on leads to costly delays, so we build that assessment into our process from day one.
Villa Park residents value the community's equestrian trails, mature landscaping, and low-density feel. We design additions and secondary units that complement this character rather than crowd it, keeping sightlines, trails, and existing trees intact wherever possible.
We visit your Villa Park property to evaluate lot size, zoning setbacks, soil conditions, and existing utilities (including septic, if applicable) before recommending a project scope.
Our team creates custom plans and handles all permitting with Orange County and Villa Park building departments, including ADU-specific approvals under current California law.
Our crews manage every phase on-site, from foundation work to final finishes, with regular updates so you always know project status.
We complete a full walkthrough with you before closeout, and every project includes a workmanship warranty for peace of mind.
We build and remodel throughout Villa Park Estates and surrounding North Orange County communities, including:
We also regularly serve Yorba Linda, Placentia, and southeast Fullerton for custom home and remodeling projects.
If you’re outside this list, call us at (213) 320-4079 we may still be able to serve your area.
Every property here is different, and pricing depends heavily on lot conditions, existing infrastructure, and project scope. As a general guide:
$60,000–$150,000

$150,000–$400,000+

$15,000–$45,000

Yes, but California's by-right ADU laws mean most projects get streamlined approval as long as they meet zoning and building code requirements. We handle the entire permitting process for you.
It depends on classification and zoning. THOWs are typically treated as accessory structures rather than permanent dwellings, and we'll walk you through what's allowed on your specific lot.
Most ADU projects take 6–10 months from initial design through construction completion, though large-lot properties with septic considerations may take slightly longer for engineering review.
Yes. Many Villa Park properties rely on septic systems, and we include a septic and soil evaluation in our site assessment before finalizing project scope.
A park model is typically a factory-built unit on a chassis, while an ADU is a permanent, permitted structure built on-site or installed as prefab on a foundation. We can help you decide which fits your goals.
Yes, we're fully licensed and insured to perform residential construction and remodeling throughout Orange County, including Villa Park's specific zoning requirements.
