ADU Company in Tustin, CA
Kitchen remodeling in Tustin is where we spend most of our time, because the city’s housing stock splits into two very different jobs: compact 1960s galley kitchens in the ranch homes of 92780, and larger 1990s-era kitchens in Tustin Ranch where the footprint is generous but the layout feels dated. Tustin’s warm inland climate means ventilation, cooling-friendly lighting, and materials that won’t warp in dry heat matter more than they do in coastal cities. Fullerton ADU Builders has served Tustin since 2017, and we approach every kitchen here as a room that has to work hard in a house built for a different generation. Call (877) 801-4497 to talk through your kitchen, your lot, and what makes sense for your budget.
Why Tustin Homes Are Different
Tustin is essentially two housing markets sharing one permit counter. The flat, older tracts of 92780 are dominated by post-war and 1960s-70s single-story ranch homes with detached garages, generous rear alleys, and kitchens that were built when a 30-inch range and a single bowl sink were enough. These homes often have solid bones but original plumbing rough-ins, galvanized supply lines, and electrical panels sized for a 60-amp era. When we open a wall in a 92780 kitchen, we expect to find surprises, and we build that expectation into the estimate. The second market is 92782, Tustin Ranch, where homes from the 1980s through 2000s sit on planned lots with HOA governance, two-story height limits, and setback rules that constrain what you can do inside and out. Warm, dry Santa Ana wind events push fire-zone awareness for any attached or detached construction, including kitchen work that touches exterior walls or venting. What all of this means in practice: a Tustin kitchen remodel is never a paint-and-counters job. It’s a careful dance between what the house gives you, what the HOA allows, and what the city will sign off on.
Our Main Tustin Services
Tustin homeowners call us about two things more than anything else: adding living space with an ADU, and fixing a primary bathroom that’s no longer pulling its weight. Both are natural fits for the lots and the housing stock here.
ADU Builders in Tustin
An ADU is the single biggest equity play most Tustin homeowners can make, and the two ZIP codes need very different playbooks. In 92780, detached garages off the rear alley are prime candidates for conversion or replacement with a detached unit, and the city’s by-right state rules mesh well with those older lots. In 92782, the HOA is often the real gatekeeper, not the city, and we’ve learned to read those governing documents early so nobody spends money on a plan that won’t pass association review. We walk you through prefab and site-built pathways, matching the unit to the lot, not the other way around. ADU Builders in Tustin covers the full process.
Bathroom Remodeling in Tustin
Tustin bathrooms in 92780 ranches are usually small, with original cast-iron tubs, failing grout, and a single vanity squeezed next to a toilet. Those jobs are about getting more function out of a tight footprint without moving plumbing far, because slab-on-grade homes here make relocating drains expensive. In Tustin Ranch, bathrooms are larger but often original to the 90s, with builder-grade tile, fiberglass surrounds, and tired layouts that need a full rework. We handle both, and we pull permits so the work is legal and resale-ready. Bathroom Remodeling in Tustin walks through what’s involved.

Kitchen Remodeling in Tustin
Kitchen remodeling in Tustin splits along the ZIP line: 92780 kitchens tend to be tight, closed-off, and starved for counter space, while 92782 kitchens are bigger but trapped in a 1990s layout with dated peninsula seating and wasted square footage. The Tustin climate matters too: inland summer heat means you want LED under-cabinet lighting that doesn’t add heat, a serious range hood that actually vents outside, and finishes that won’t swell or fade in dry, hot air. Fullerton ADU Builders has served Tustin since 2017, and our approach starts with a free estimate that gives you line-item pricing, so you can see exactly where the money goes before you decide anything. If you’re also thinking about an ADU, Kitchen Remodeling pairs naturally with a detached unit, letting one contractor handle both scopes and one permit package cover more ground.
Galley Kitchen Opening
Signs you need it
A galley kitchen in a 92780 ranch feels like a hallway you cook in, with one cook bumping into open cabinet doors and no line of sight to the dining room.
What it costs in Tustin
Opening a galley kitchen by removing a load-bearing wall, adding a beam, and reflowing the space typically runs $45,000 to $75,000 in Tustin.
How we do it
We verify load path and existing foundation support, pull structural plans and permits, install the beam and drywall, then rebuild the kitchen in the opened footprint.
Full Gut and Relayout
Signs you need it
The cabinets are particleboard, the layout puts the refrigerator in a corner, and nothing about the work triangle works for how you actually cook.
What it costs in Tustin
A complete gut and relayout in Tustin, including new plumbing, electrical, cabinetry, counters, and flooring, runs $65,000 to $110,000.
How we do it
We strip the room to studs, move plumbing and electrical to the new layout, rebuild with today’s cabinet dimensions, and close out with a city final inspection.
What Kitchen Remodeling Costs in Tustin
| Item | Typical range in Tustin |
|---|---|
| Galley kitchen opening (with beam) | $45,000 – $75,000 |
| Full gut and relayout | $65,000 – $110,000 |
| Cabinet reface with new counters | $18,000 – $30,000 |
In Tustin, the two biggest price drivers are load-bearing walls (common in 92780 ranches) and HOA-required design review (common in 92782). We give written, line-item quotes before work starts and don’t change the number once the contract is signed.
How long does a kitchen remodel take in Tustin?
A typical Tustin kitchen remodel runs six to ten weeks from demo to final inspection. Working inside an HOA in Tustin Ranch can add two to three weeks for design review on the front end, so we file those documents early.
Will my HOA approve a kitchen remodel?
Most Tustin Ranch HOAs approve interior kitchen remodels without much friction, as long as exterior-facing changes like vent hoods or window swaps are disclosed. We submit the design package for you, call (877) 801-4497 to get started.

FAQs About ADU Company in Tustin
Most Tustin projects start within two weeks of permit approval, and our planning work often starts within a few days of your first call. Prefab ADU orders carry manufacturer lead times; we map the full schedule for you before you sign anything.
In 92782, yes: most Tustin Ranch communities require HOA design review for any exterior change, including ADUs, and some require it for visible interior venting. In 92780, most homes are not governed by an HOA, so city permits are the only gate.
Yes, that’s one reason homeowners bring both scopes to us. One contractor, one permit package, one schedule, and one point of contact for your kitchen remodel and your new Tustin ADU. Call (877) 801-4497 for a free estimate that covers both.

What Tustin Customers Say
"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Erin Ziegler"Garage conversion to a one bedroom unit. He handled the plans, the city submittal, and every round of corrections. Took six months from first meeting to final inspection and he never once made the permit process my problem."
— Tim Padgett"The kitchenette layout he suggested made better use of the space than the one on our original sketch."
