ADU Company in Tustin, CA
Kitchen remodeling in Tustin usually runs $18,000 – $42,000 for a full gut-and-replace, with partial updates landing closer to $9,000 – $17,000. What makes Tustin jobs different is the housing stock: mid-century ranch homes in 92780 tend to have tight galley kitchens and original plumbing, while 1990s and 2000s builds in 92782 have oak-heavy cabinets and soffits that date the whole room. Foundry ADU Builders handles kitchens as part of a larger ADU project or as a standalone remodel, and we scope every job to the era of the house. Call (866) 251-7857 for a free estimate.
Why Tustin Homes Are Different
Tustin’s housing is split into two distinct worlds, and the kitchen work reflects that. In the 92780 ZIP, you’re mostly looking at 1950s-to-1970s single-story ranch and stucco tract homes. These were built when kitchens were closed off from living space, with narrow doorways, original cast-iron drain lines, and electrical panels that predate modern code. A full remodel there often means opening walls, moving plumbing, and upgrading the panel before a single cabinet goes in. In 92782 – Columbus Square, Tustin Ranch, and the surrounding planned communities – the homes are newer but heavily HOA-governed. Kitchen work inside the house rarely needs HOA approval, but anything that changes exterior venting, window size, or a visible hood termination can trigger architectural review. Tustin’s inland Orange County climate also shapes the work: hot, dry Santa Ana periods and mild winters mean ventilation and exhaust performance matter more than insulation, and wildfire-smoke days push us toward sealed, filtered range hoods and better indoor air handling. The old MCAS Tustin land around Tustin Legacy is still being redeveloped, and homes bordering those newer parcels can have surprising lot-line and easement quirks that affect any remodel tied to an ADU or an addition.
Our Main Tustin Services
Most Tustin homeowners reach out to us for one of two things: building an ADU from the ground up, or remodeling a bathroom inside an existing home or a newly built accessory dwelling unit. Both services run on the same local knowledge of Tustin’s permit office, HOA realities in 92782, and the older-home conditions common in 92780.
ADU Builders in Tustin
Tustin’s ADU landscape is driven by lot geometry more than almost anything else. The 92780 neighborhoods around Old Town sit on generous lots where detached units and garage conversions make sense, while the 92782 planned communities lean toward attached ADUs, junior units, and conversions that work within tighter setbacks and HOA design rules. We match the build method – site-built, modular, or factory prefab – to your specific parcel, because a plan that sails through in one Tustin ZIP can stall in the next. We also verify lot lines and any prior-use records tied to the old MCAS Tustin land, which matters more than people expect. Read the full breakdown on our ADU Builders in Tustin page.
Bathroom Remodeling in Tustin
Bathroom work in Tustin tends to fall into two buckets: refreshing a 1970s-era bathroom in a 92780 ranch home, or finishing out a bath inside a newly permitted ADU. The older homes often have water-damaged subfloors around tubs and showers, galvanized supply lines, and inadequate venting that lets moisture sit. The ADU side is cleaner – new plumbing, new waterproofing, new fixtures – but still needs to pass Tustin’s inspection standards the same as any primary-home bath. We handle both under one contractor relationship, so an ADU shell and its finished bathroom never get handed off between crews. See the full scope on our Bathroom Remodeling in Tustin page.

Kitchen Remodeling in Tustin
Kitchen remodeling in Tustin typically costs $18,000 – $42,000 for a full renovation and $9,000 – $17,000 for a partial update, with the spread driven by cabinet grade, appliance choices, and how much plumbing and electrical work the existing room needs. In 92780, where mid-century ranch homes dominate, we’re usually removing a load-bearing wall, relocating drains, and rebuilding the kitchen as the open space it never was. In 92782, the work is more cosmetic – cabinet replacement, countertops, backsplash, lighting – but HOA rules can still shape the timeline if venting or windows come into play. Foundry ADU Builders carries kitchen work as a core service because ADU interiors and primary-home kitchens share the same finish standards: we’re a single contractor from rough-in to final trim.

Cabinet Replacement
Signs you need it
Hinges are pulling out of particleboard, drawer slides are failing, or the cabinet layout simply doesn’t work for how you cook.
What it costs in Tustin
Cabinet replacement in Tustin typically lands between $12,000 and $28,000 depending on whether you choose stock, semi-custom, or full custom boxes and doors.
How we do it
We measure the full run, order or fabricate the boxes and faces, demo the old cabinets, and install with shims and level checks so every drawer closes clean.
Countertop and Backsplash Upgrade
Signs you need it
Counters are chipped, stained, or dated tile with failing grout, and the backsplash no longer protects the wall from splatter properly.
What it costs in Tustin
Countertop and backsplash upgrades in Tustin typically run $6,000 to $15,000 including fabrication, templating, and installation labor.
How we do it
We template the existing base cabinets, fabricate the stone or solid-surface top, and install the backsplash with waterproof grout and sealed edges.
Full Kitchen Renovation
Signs you need it
The entire room works against you: bad layout, old wiring, failing floors, and plumbing that needs to move or risk failing inspection during any future sale.
What it costs in Tustin
A full kitchen renovation in Tustin typically falls between $18,000 and $42,000, covering demo, framing changes, plumbing, electrical, flooring, cabinets, counters, and finish work.
How we do it
We demo to studs where needed, reframe any openings, rough in plumbing and electrical, then rebuild the room in layers – drywall, flooring, cabinets, counters, tile, and trim.
What Kitchen Remodeling Costs in Tustin
| Item | Typical range in Tustin |
|---|---|
| Cabinet replacement | $12,000 – $28,000 |
| Countertop and backsplash upgrade | $6,000 – $15,000 |
| Full kitchen renovation | $18,000 – $42,000 |
These ranges reflect Tustin’s mix of 1950s-70s ranches and 1980s-2000s planned-community homes. Older homes push toward the high end when plumbing and electrical upgrades are required; newer homes in 92782 often land mid-range because the structure itself is sound.
How long does a kitchen remodel take in Tustin?
A full Tustin kitchen remodel usually takes 6 to 10 weeks from demo to final walkthrough. Cabinet replacement alone can finish in 2 to 3 weeks. Permit review times at the city and any HOA approval in 92782 can add 2 to 4 weeks before work starts. Call (866) 251-7857 for a timeline based on your specific scope.
Will my Tustin kitchen remodel need a permit?
Yes, any kitchen remodel in Tustin that changes plumbing, electrical, or structural walls requires a city permit. Cosmetic work like cabinet replacement and backsplash tile may not. We pull all needed permits and schedule the inspections ourselves. Call (866) 251-7857 and we’ll confirm what your project triggers.

What pushes a Tustin kitchen price up is almost always the age of the house: cast-iron drain lines in 92780 ranches, undersized electrical panels, or a wall that needs structural work before it can come down. HOA design review in 92782 can add time but rarely adds cost unless the HOA mandates specific exterior-visible materials. Every estimate we give is a written line-item quote, and we don’t change the price once work starts unless you change the scope.

What Tustin Customers Say
"Unit came out great and the tenant is happy. The timeline ran long, largely because of how slow the city was on plan check, though a couple of the delays were scheduling on their end."
— Holly Reed"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
— Shannon Gallagher"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."
— Marisol Delgado
