Find the top ADU construction companies in Buena Park, CA! Hire the right team for your project today.
Let’s be honest; when you’re planning an ADU (Accessory Dwelling Unit) in Buena Park, you’re not just building an extra room or income suite. You’re building space for family, for memories, maybe even for a little peace and quiet (finally).
Whether it’s for aging parents, adult kids, or a little side income, your ADU project has real emotional weight behind it. And picking the right contractor? That’s half the battle.
In a city like Buena Park, where weekends are spent with the kids at Knott’s Berry Farm or walking the trails at Boisseranc Park, you want a team that understands the local flow—how to navigate city regulations, handle tight backyards, and still deliver something that neighbors compliment you on for years to come.
That’s why choosing the right ADU contractor matters. This isn’t just about who’s cheapest or fastest; it’s about who gets you, your goals, and your corner of the neighborhood.
Starting With Cornejos Builders
At Cornejos Builders, building ADUs isn’t just something we do—it’s what we’ve spent years getting really good at. We’re a family-run team rooted right here in SoCal, and when we take on a project, it’s personal. We’re not the kind of folks who disappear after demo day or give you vague timelines.
We’re the ones who answer your calls, show up when we say we will, and actually care about the final result like it’s our own home.
We specialize in turnkey ADU construction, which means we take care of every step—from initial designs and city permits to final inspections. You don’t have to juggle five different people and hope it all comes together. We handle it, and we keep you looped in the whole way through. It’s one team, one clear plan, and no surprises.
Homeowners in Buena Park trust us because we know the local codes and quirks. We’ve worked with Buena Park City Hall enough times to know what flies and what gets stuck in permit purgatory. That matters when you’re trying to add square footage without the headaches.
We back up our work with a 1-year workmanship warranty, and our timelines are realistic—no lofty promises, just solid planning and honest delivery. We also use top-grade materials and licensed subcontractors who know the terrain, especially with SoCal’s unpredictable clay soils and summer heat.
What really sets us apart? We don’t just build structures—we build trust. We’ve had clients bring us back for second and third projects because they know we’re straight shooters. We’ll tell you if something’s not worth the cost. We’ll suggest alternatives that fit your goals. Heck, we’ve even talked people out of building when it wasn’t the right time.

Alex is very responsive and easy to talk with. He was highly endorsed by a satisfied coworker with whom he completed a roof project. Alex and his team Cornejos Builders Inc completed our roof project quicker than expected.
He came on-site and explained thoroughly the work they have done to our roof. The workers are very professional as well, they cleaned up after the job was done, and it was not messy at all. I will be using Cornejos Builders Inc in the future
