About ATP Builders
ATP Builders is a precision-led residential construction firm serving homeowners throughout Newport Beach and coastal Orange County who value clarity, craftsmanship, and a process that holds together from start to finish.
Built Around a Straightforward Belief
We built this company around a straightforward belief: construction should feel organized, transparent, and well-executed from the first conversation to the final walkthrough. Every project we take on is guided by a single standard. If we would not build it for our own family to live in for decades, we do not build it that way for yours.
Four principles guide our work, not as aspirational statements, but as the operating standard applied to every project in our portfolio.
Clarity in process.
Every project starts with a defined scope, clear milestones, and a plan that holds from day one through final delivery.
Craftsmanship that lasts.
We build every home as if the family living in it will pass it down. Material and structural decisions are made for longevity.
Transparency in communication.
You always know where your project stands — not just at the start, but throughout the build with consistent, honest updates.
Seamless execution.
One team, one standard, one point of accountability from the first conversation through the final walkthrough.
Experience You Can Rely On
ATP Builders brings over 50 years of combined residential construction experience across Southern California.
We specialize in custom home construction, whole-house remodeling, home additions, and design-build project delivery. Our background spans pre-construction planning, construction management, and residential design coordination, ensuring every phase is handled with precision from the beginning.
We partner with homeowners on projects that require serious planning, structured execution, and a team that can hold the full scope clearly from day one.

How We Work
For homeowners who prefer a single team from concept through construction, ATP's integrated approach brings architecture, planning, and execution under one roof. One team, one clear point of accountability, and consistent communication throughout.
For homeowners who already have an architect or designer they trust, we work as your builder. The same clear process, the same communication standard, and the same craftsmanship apply, without asking you to start over with a new design team.
Either way, the build standard is the same.
Credentials
ATP Builders holds California Contractor License No. 1013886 and is a US Bank Approved Contractor. These reflect the institutional accountability we carry into every project, and the standard we hold ourselves to before, during, and after the build.
