Lodgewick ADU Builders handles accessory dwelling units, garage conversions, and home additions across North Tustin. If you’re weighing an ADU on a large estate-style lot here, you’re likely looking at a project that needs to match an existing mid-century ranch or split-level home, meet county zoning allowances, and hold up to Santa Ana winds. That’s different from a standard backyard cottage job in a newer tract. We’re the ADU company of the Kingswell family, and every North Tustin project runs under The Kingswell Guarantee: a written price before work starts, a defined arrival window, a clean job site, and a written guarantee. Call (350) 203-6060 for a free estimate.
Why North Tustin Homes Are Different
North Tustin’s unincorporated status shapes ADU work more than most homeowners expect. Projects here go through county-level zoning rather than city review, and many lots carry neighborhood-specific design expectations from longtime neighbors and local architectural norms. Homeowners rarely want a prefab box dropped beside a 1960s ranch. They want a unit that reads as part of the original property.
The housing stock backs that up. Mid-century ranch and split-level homes dominate, many with original wood framing and single-glazed windows. That means any ADU project usually includes retrofitting for modern energy codes and seismic resilience, even when the existing house stays untouched. The warm Mediterranean climate adds another layer: efficient cooling, passive ventilation, and fire-resistant materials matter, especially for lots near canyon edges where Santa Ana winds push fire risk higher in late summer and fall.
The result is what we call a matching ranch ADU: a unit that mirrors the original roofline, window trim, and single-story silhouette. These projects take more design care than a stock backyard cottage, but they protect property value and keep neighbors happy.
Our Main North Tustin Services
North Tustin homeowners call us most often about three things: expanding the main house, turning an underused garage into livable space, and building a standalone ADU. Each service has its own page with specifics.
Home Addition Contractor in North Tustin
A home addition in North Tustin usually means extending a single-story footprint outward rather than up, keeping the roofline consistent with neighboring ranch homes. Many additions here trigger energy-code upgrades on the existing structure, so budgeting should account for insulation and window retrofits alongside new square footage. Russ Delmar, our leader, has guided dozens of these projects through county permitting. Home Addition Contractor in North Tustin
Garage Conversion Contractor in North Tustin
Garage conversions in North Tustin often involve detached garages from the original build, which gives you more design freedom but also means running new utility lines across the lot. Older garage slabs here sometimes need structural work before framing can begin. We handle the full scope, from county permits to final inspection. Garage Conversion Contractor in North Tustin
ADU Builders in North Tustin
Standalone ADUs on North Tustin’s estate lots can go larger than typical California ADUs, and many homeowners choose detached units with their own address, parking, and private entrance. We work with established prefab manufacturers like Dvele and Boxabl when the lot suits modular delivery, and stick-frame builders when the design needs to match a custom ranch style.

FAQs About ADU Company in North Tustin
Most North Tustin ADUs take 8 to 14 months, with about a third of that time spent on county permits and design review. Unincorporated lots sometimes require extra weeks for neighbor notification and zoning checks. We give a written timeline with your written price before anything starts.

Yes. North Tustin is unincorporated Orange County, so ADU permits go through county offices rather than a city building department. The good news: county staff are consistent, and we handle the paperwork end to end. Your written price includes all permit fees.
Not by law, but strongly by neighborhood expectation. Many North Tustin streets have an informal standard of matching rooflines and materials, and a well-matched ADU protects resale value. We design matching ranch ADUs by default and will show you your options before you commit to anything.
