About Bernal Builders
A Family Business Built on Trust and Craftsmanship
Bernal Builders started as a small, family-run operation helping neighbors with repairs and small projects. Over the years, that same hands-on approach grew into a full-service construction company focused on ADUs, garage conversions, home remodels, and additions across San Diego.
We know inviting a contractor into your home is a big decision. That is why we focus on clear communication, honest budgets, and doing what we say we are going to do. Many of our projects come from referrals and repeat clients—families who trust us to keep building with them over time.
As a licensed general contractor in San Diego, we understand local codes, coastal conditions, and the unique charm of each neighborhood we work in.
