Fast, Reliable General Contractor Across North Tustin
Hiring a general contractor in North Tustin means finding someone who understands what sits behind the walls of a 1950s-70s ranch home and knows how OC Public Works will review the permit. We’re Key Step Construction, led by Noel Garrity, and we’ve spent years working on exactly the houses that define this unincorporated Orange County community. Our team handles full-scope remodels, additions, and ADUs from the first inspection through final sign-off. If you’re planning a kitchen overhaul, a second-story addition, or a whole-home renovation, call (855) 382-0824 to schedule a free estimate and get a written plan before you commit.
Why Key Step Construction Is North Tustin’s Preferred General Contractor Company
North Tustin homeowners don’t want a contractor who treats their home like a tract house in Irvine. The lots are bigger, the homes are older, and the county permit process is different from anything in neighboring Tustin or Santa Ana. We know the ZIP code 92711 well enough to anticipate what plan check will flag before we even file. Our clients across neighborhoods near Newport Avenue, Foothill Boulevard, and Cowan Heights call us back because we write allowances into the contract for the wiring, framing, and waterproofing surprises that mid-century homes always seem to hide.
The reviews we hear most from North Tustin customers are about our change-order discipline. When we open a wall and find aluminum wiring or a rotted top plate, we stop, document it, price it, and get a signature before we proceed. No one gets a surprise bill at the end of the job. That’s how Noel Garrity has structured every Key Step project since day one: plan it once, build it right.
Response time matters too. Our Buena Park operation is close enough that we can get a crew to North Tustin within a day for estimates and site walks, and we schedule inspections around the county’s availability, not the other way around.

Licensed General Contractor in North Tustin
A Licensed General Contractor in North Tustin handles the structural, electrical, plumbing, and finish work under one contract, and because North Tustin is an unincorporated county island, that contractor has to navigate OC Public Works permitting at every step. When a homeowner plans a home addition that runs $45,000 to $130,000, or a kitchen remodel that ranges from $14,000 to $45,000, the license is the difference between a permitted, insurable project and a liability you’ll carry for years. We’re licensed in California and carry every project through plan check, inspection, and final sign-off.
What the Permit Process Actually Requires
North Tustin remodels and additions go through OC Public Works, not a city hall. The county reviews grading, drainage, and fire-hardening on a level that most homeowners have never encountered. We file the plans, attend the inspections, and handle corrections directly with the county reviewers.
When Hidden Damage Changes Scope
Original wiring, failed shower pans, and undersized joists are the rule, not the exception, in North Tustin’s ranch-era housing stock. We write allowances into every contract so those discoveries get priced and approved before any additional work begins.
Residential General Contractor in North Tustin
A Residential General Contractor in North Tustin manages the whole house: roof, windows, siding, kitchens, baths, and additions. Because the housing stock here is dominated by mid-century ranch homes and custom estate parcels on half-acre-plus lots, most projects are remodels and rebuilds rather than new construction. That means every job starts with knowing what condition the original 1950s-70s systems are actually in. A bathroom remodel in North Tustin runs $9,000 to $28,000, and a roof replacement runs $8,000 to $20,000. We coordinate every trade under one contract so you’re not juggling a plumber, an electrician, and a roofer on your own.
Foothill Lots and Drainage Reality
The eastern edges of North Tustin sit up against wildland-urban interface territory, and county inspectors scrutinize grading and drainage plans after every Santa Ana wind and rain cycle. That extra review can delay a draw schedule if the plan wasn’t prepared for it. We build that timing into our schedule from day one.
One Contractor, Every System
From the roof down to the foundation, we carry the project across every system of the home. James Hardie siding, GAF roofing, and Schluter waterproofing are part of our standard toolkit. No subcontractor juggling on your end.
Trusted Brands We Service in North Tustin
We work with over 50 vetted material brands, but for the fencing and exterior scopes common on North Tustin’s large estate lots, we regularly install Master Halco and Bufftech systems. Those are brands with real product warranties behind them, and we know how to install them to the manufacturer’s spec. When a North Tustin homeowner replaces an old wooden fence with vinyl or aluminum, we typically have materials on order within days and crews scheduled around county inspections, not independent of them. Built to the brand’s spec is not a slogan for us; it’s how the warranty stays valid.

AfterCommon General Contractor Problems We See in North Tustin Homes
- Aluminum wiring behind the drywall. Homes built in the 1950s and 1960s across North Tustin often still carry original aluminum branch circuits. Any remodel that opens those walls triggers a county requirement to upgrade the circuits we touch, so we scope for it before the bid, not after.
- Undersized framing that fails plan review. Second-story additions need load calculations that mid-century ceiling joists rarely satisfy. We opened a 1962 ranch home off Newport Avenue and found joists that could not carry the new primary suite, so the framing upgrade went into a signed change order before we proceeded.
- Flat roof sections leaking into top plates. The low-pitch and flat roof sections common on North Tustin ranches hide water damage for years. By the time we open the wall, the top plate and sometimes the studs need replacement, a cost no one wants to discover mid-remodel without a written allowance.
- OC Public Works grading and drainage review delays. Unincorporated North Tustin remodels get extra scrutiny on drainage, especially after Santa Ana wind events. Homeowners who treat the permit like a city permit in Orange or Tustin get stalled draw schedules and missed inspection dates. We file with the county’s additional review in mind from the start.

FAQs About General Contractor in North Tustin
Because North Tustin is an unincorporated county island, the county is the permitting authority, and OC Public Works reviews and inspects all construction work. That means grading, drainage, and fire-hardening review that neighboring Tustin or Santa Ana would not apply. Call (855) 382-0824 and we’ll walk you through what your project would trigger.
The typical surprises are original aluminum wiring, undersized ceiling joists, dry rot at top plates from flat roof leaks, and failed waterproofing behind old shower pans. We scope for all of it before the bid and write allowances into the contract so those costs never hit you unannounced.
We stop work, document the damage with photos, price the repair or upgrade in writing, and get your signature before any additional work begins. No crew touches a joist or a circuit until the change order is approved. Call (855) 382-0824 and we’ll show you a sample allowance structure.
Yes, additions near the wildland-urban interface on the eastern foothill edges typically require ember-resistant venting, Class A roofing, and defensible-space compliance as part of plan check. We build those upgrades into the permit set before we file, so plan review doesn’t stall.
You can, but the county’s inspection and plan check process for unincorporated North Tustin is unforgiving on grading, drainage, and fire code, and a missed review can delay the draw schedule by weeks. Most homeowners end up paying more in time and re-file fees than they saved, which is why they hire us for the whole scope. Call (855) 382-0824 for a free estimate before you decide.
