ADU Construction: Quality Additions & Accessory Dwelling Units
Turn your backyard into income, independence, or in-law comfort—with a custom ADU built to fit you
Building accessory dwelling units (ADUs) or home additions with Builder Buddies is a collaborative, transparent process designed to keep you informed and confident every step of the way. We begin with a personalized consultation to understand your goals—whether it’s creating space for family, generating rental income, or adding long-term value to your property. From there, we guide you through design and permitting, ensuring your plans meet local codes and reflect your vision. Once approved, we move into site prep and foundation work, followed by framing, electrical, plumbing, and insulation—all handled by skilled professionals who treat your home with care. The final stages include drywall, finishes, and inspections, leading to a clean, on-time handoff.
What sets Builder Buddies apart isn’t just the quality of our work—it’s the way we show up for you. We understand that adding to your home with an ADU or an addition is a big decision, and we honor that with clear communication, realistic timelines, and honest pricing. We’re not just builders—we’re neighbors, parents, and community members who care deeply about the families we serve across Contra Costa County. With Builder Buddies, your ADU or home addition isn’t just built—it’s thoughtfully crafted to fit your life, your future, and the people who matter most.
