How Westminster ADU Builders Was Born in Westminster

We started this company in 2016, but the moment that pushed us over the edge happened about a year earlier. We were called to a home near Bolsa Chica Road where a previous contractor had framed an ADU addition and then simply vanished. The homeowner had a shell of a structure sitting in her backyard for eleven months. No drywall. No stucco. The electrical rough-in was exposed and the city had red-tagged the project. She was paying a storage unit to hold the kitchen cabinets she’d already ordered, and the bank had frozen her construction loan. When we walked the property, she didn’t ask for a quote first. She asked if we were going to disappear too.

That question stuck with us. We’d been in the building trades for a decade at that point, and we kept hearing the same stories across Westminster: deposits collected, schedules slipped, phone calls ignored. The ADU industry was booming because California had made it easier to permit, but the problem was never the paperwork. The problem was trust. We worked on that job for six months, and when the homeowner finally got her certificate of occupancy, she stood in the doorway of a finished one-bedroom unit and said, “I didn’t think anyone actually finished these.” We knew then that the bar in this trade was too low, and we wanted to be the company that raised it.

So we built Westminster ADU Builders with a simple promise: do the work we say we’ll do, tell the truth about what it costs, and stay on the job until it passes final inspection. That’s the whole founding story. It wasn’t a business plan written in a boardroom. It was a reaction to watching too many Westminster homeowners get left holding an unfinished frame and a pile of receipts.

Our Founder’s Personal Connection to the ADU Trade

We didn’t grow up dreaming about accessory dwelling units. We grew up around people who built things with their hands, and we learned early that there’s a particular smell to fresh-cut lumber, concrete dust, and warm drywall mud that means progress. Our first real taste of construction was doing grunt work, hauling materials, cleaning up job sites, holding the dumb end of the tape measure. We weren’t old enough to drive, but we could read a set of plans before we could read a novel cover to cover. The trades got in our blood through repetition and proximity, the way anything meaningful does.

The moment ADUs became the thing we cared about most came later. We were working on conventional remodels, kitchens and bathrooms mostly, and we kept noticing the same pattern: people weren’t doing those projects for luxury reasons. They were doing them because their families were changing. Aging parents moving to California and needing a place to land. Adult kids who couldn’t afford Westminster rents. Siblings and cousins and close friends who needed a hand. The home was becoming multi-generational in a way the floor plans never anticipated. And an ADU was the answer sitting right there in the backyard.

Once we saw that, we couldn’t unsee it. An ADU isn’t a shed with drywall. It’s a bedroom for a grandmother, a first apartment for a twenty-something, a quiet office for someone who works from home. It’s also the single smartest investment a Westminster homeowner can make given what housing costs here now. That’s what gets us out of bed on a Monday morning: knowing the structure we frame this month will be someone’s home by the holidays. Not a house. A home. With a person in it, making coffee in the morning, arguing with the thermostat, living a life. If we weren’t doing this, we’d probably be building something else with our hands, furniture or cabinetry or decks. But we’d miss the part where a client walks through a finished unit and realizes their family just got bigger without leaving the property.

We’ve been at this for more than a decade now, and the work still feels personal. Every job site teaches us something new. Every homeowner has a different reason for building an ADU, and hearing those reasons is part of the trade. We’re not the kind of company that treats this as a production line. We’re the kind that remembers the way the afternoon light hits the kitchen window of the unit we just finished, and the look on a client’s face the first time they walk through the door.

Meet Our Team – The Person Behind Every Job

Our founder and owner has spent his entire professional life in construction, starting as a laborer and working through every trade before landing on ADUs as a specialty. The title is Owner & Founder, but the deeper truth is that he’s still the guy who wants to walk every job site, check the flashings, and ask the framing crew a question about a wall detail. He holds the required state credentials, carries the insurance and bonding any legitimate contractor in California needs, and has spent the last ten years focused specifically on accessory dwelling units in Orange County.

What makes him different from a franchise technician with a logo on a truck is straightforward: he lives with the reputation of every structure he builds. This isn’t a territory assignment. It’s his community, his name, and his standard of work. When he’s not on a job site, he’s the kind of person who can’t walk past a half-finished project without mentally finishing it. He restores old tools not because they’re collectible, but because he thinks things built well deserve to keep working. That same instinct carries into every ADU we build: we don’t want the work to just pass inspection. We want it to outlast us.

We’re committed to every homeowner who trusts us with their backyard. That’s not a slogan. It’s the only way we’ve ever worked.

Our Promise to Westminster Homeowners

Three values guide every project we take. They’re not aspirational. They’re operational.

Honest pricing. We provide a free written estimate before any work begins, and the estimate is line-item detailed. No lump sums with a wink. No “we’ll figure it out later.” If the price changes during construction, it’s because the scope changed, and you’ll know before we pick up a tool. Change orders are agreed to in writing, never sprung on you mid-project.

Quality materials and workmanship. We use products and methods that are appropriate for Orange County’s climate: stucco done right for the coastal air, strapping and shear details built for seismic code, drainage that actually works when it rains in January. We don’t cut corners, and we don’t use materials we wouldn’t put on our own homes.

Standing behind every job. When we finish an ADU, we don’t consider the relationship over. If something isn’t right, call us. We’ll come back and make it right. That’s the whole point of the company we started in 2016.

Our Credentials

Here’s what a Westminster homeowner should know about the people working on their property:

  • State-licensed contractor – Required by California law for any ADU construction project. We hold the credentials required for residential building work in this state.
  • Insured & bonded – Protection for you, your property, and our crew. If something goes wrong, you’re not left holding the bag.
  • A decade of local experience – We’ve been building ADUs in Westminster and surrounding Orange County cities since 2016. That’s enough time to know the local building department, the inspectors, the soil conditions, and the neighborhoods.
  • Strong local reputation – We’ve built our business on referrals from happy homeowners. When your neighbors recommend us, that’s the credential that matters most.

Each of these matters for a simple reason: you’re inviting a team into your backyard and investing a substantial amount of money in a structure your family will live in. You deserve to know the people doing that work are legitimate, accountable, and experienced. No homeowner should ever feel like they’re gambling on an unknown. Our credentials exist to remove that gamble.

Rooted in Westminster

We work all over Orange County, but Westminster is home. We know the difference between the neighborhoods near Little Saigon and the streets over by Bolsa Chica Wetlands. We know how the marine layer sits over the 405 corridor in late spring and how that affects curing concrete. We’ve watched the city’s ADU program evolve, we know what the planning desk wants to see on a submittal, and we’ve built relationships with the local inspectors that make the permitting process smoother for our clients. When we say we’re rooted in Westminster, we mean we’re here, permanently, and our work is visible in backyards all over this city.
