How Foundry ADU Builders Was Born in Brea
It started with a phone call from a homeowner in Brea who was nearly in tears. She had spent most of a year trying to get an ADU built in her backyard. Two contractors had come and gone. One walked off the job over a permitting dispute he never mentioned until the check was cashed. The other kept adding change orders for things that should have been included from day one. She was exhausted, out a lot of money, and had a concrete slab sitting behind her house like a monument to every promise that never got kept.
We got the call because someone she trusted asked us to take a look. We walked the site, pulled the partial permits, and sat at her kitchen table while she showed us the stack of invoices. Nothing about it was complicated. The project just needed someone who would do what they said they’d do. We finished her ADU in Brea later that fall. She rented it to a young couple the following spring. That experience, and others like it, told us something we already suspected: this trade needed fewer sales pitches and more people who treat a backyard home like it matters. Because it does.
We founded Foundry ADU Builders in 2018 because Brea and the surrounding cities deserve better than what we kept seeing. Our promise was simple then and hasn’t changed: show up, tell the truth, build it right, and stand behind it.
Our Founder’s Personal Connection to the ADU Trade
The first framing hammer we ever held wasn’t on a job site. It was in a garage in Brea, helping a family member patch a wall after a bad storm. We were young, and the work felt like a chore until we stepped back and looked at the finished wall. It was straight. It was solid. It was done. Something about that clicked. The smell of cut lumber, the weight of a nail gun, the way a good measurement feels when it lands exactly where it’s supposed to. We didn’t know it then, but that was the beginning.
Years later, after working alongside tradespeople who cared deeply about their craft and others who cared only about volume, we found our way to ADUs. There was something about the scale of it. A single-family home is a symphony. An ADU is a quartet. Every decision matters more because there’s no room to hide. The framing has to be right the first time. The electrical layout has to work with the client’s life, not just the code. The roofline has to feel like it belongs in the backyard, not dropped in from a catalog.
What gets us out of bed is the finished threshold. The moment a homeowner opens the door of a unit that didn’t exist six months earlier and walks through it like it’s been there forever. That’s the thing that never gets old. If we weren’t building ADUs, we’d probably be teaching. Not in a classroom, but on the job, the way we learned. Watching someone understand why a wall layout works, or why you flash a window a certain way in Brea’s dry heat, is its own kind of satisfaction.
We’ve been in this work for more than a decade now. Long enough to know that the skills matter, but the listening matters more. Every ADU starts with a conversation about someone’s life: an aging parent moving in, a grown child who can’t afford rent, a tenant whose rent will offset the mortgage. That’s not just framing and drywall. That’s family. And we’ve never lost sight of it.
Meet Our Team – The Person Behind Every Job
Foundry ADU Builders is led by its owner and founder, the person whose story this is. We’re a local operation, not a corporate franchise with rotating crews you’ll never see twice. The training is hands-on, earned through years on actual job sites across Brea, La Habra, Placentia, Fullerton, and the surrounding cities. The approach is old-fashioned in the best way: answer the phone, return calls, keep appointments, and never let a client wonder what’s happening.
Why do we do it this way? Because we’re the ones who show up. The person who measures your setback, walks you through the permit process, and walks the framing before the drywall goes up is the same person you called on day one. When a question comes up mid-project, you won’t wait three days for a callback. You’ll hear from someone who knows your project, not someone reading from a file.
Our commitment to every homeowner in Brea is straightforward: if we take your job, we’re all in. You’ll never be handed off to someone who doesn’t know your name, your timeline, or your budget. That matters to us. It’s how we’d want to be treated if someone were building in our own backyard.
Our Promise to Brea Homeowners
Honest pricing means a written, line-item estimate before you sign anything. No vague allowances. No “we’ll figure that out later.” If a change comes up, we talk about it in writing before a single board is cut. You know what you’re paying, and why. That’s not a selling point. That’s basic respect.
Quality parts and materials matter because an ADU is a home, not a shed. We’re selective about what we install, from the foundation to the roof. We’ve worked with products from manufacturers like James Hardie and Plant Prefab when the project calls for them, and we’ll explain why a certain material makes sense for your particular site, your soil, your sun exposure, and your budget.
Standing behind every job means we don’t disappear after the final inspection. If something isn’t right, you call us, and we address it. Every home we build is a reflection of us in a community we live and work in. We don’t take that lightly.
Our Credentials
When you’re inviting someone to build on your property, you need to know the basics are covered. Here’s what you can expect when you work with Foundry ADU Builders:
- State-licensed. Every pro working under our name is required to hold the license and insurance their state requires. No exceptions.
- Insured & bonded. You’re protected while work is underway. If something goes wrong, you’re not left holding the bag.
- Local experience. We’ve been building in Brea and the surrounding North Orange County cities since 2018, working with local building departments and permit offices.
- Strong local reputation. Our work comes primarily from referrals, which tells you everything about how we operate.
Here’s why these credentials matter to you as a homeowner. A license means the contractor has met state standards and can be held accountable through official channels. Insurance and bonding protect you from liability if someone is hurt on your property or if work is left unfinished. Local experience means we know which Brea planning requirements apply to your specific lot and which inspectors expect what, which saves you time and frustration during the permitting phase.
Rooted in Brea
We work here. We live here. We know the difference between the setbacks in the older neighborhoods near Brea Downtown and the newer developments up in the hills. We know that the sun hits a west-facing wall in Carbon Canyon differently than one near the Brea Mall. We’ve celebrated at local Fourth of July parades, grabbed sandwiches at delis on Brea Boulevard, and gotten to know the rhythm of a city that cares about how it grows.
That’s why we build the way we do. Not as strangers passing through, but as people who’ll drive past our own work for years to come. We want every ADU bearing our name to be one we’re proud to claim.
Call (866) 251-7857 to schedule your free estimate. We’ll walk your yard, listen to your goals, and tell you honestly what’s possible. No pressure, no obligation, just straight answers from people who know this work inside and out.
