North Bay's Trusted Custom Home Builder Since 1924
Our Legacy of Excellence
Who We Are
Moll Construction is a fourth-generation builder based in Sonoma Valley, rooted in craftsmanship, integrity, and service to the North Bay. Our story began more than two decades before 1948, when the City of Sonoma issued its first building permit to our great-grandfather, and it continues through thousands of homes and buildings across Marin, Sonoma, and Napa counties. From building in the Bay Area, expanding to Lake Tahoe, and have since returned to Sonoma as the next generation takes the helm. For a century we have helped shape the North Bay, including work throughout the Historical Sonoma Plaza, to the vineyard laced hilltops with incredible views, from careful restorations to full rebuilds....

Testimonials
“We had no idea where to start. Casey walked us through the steps, explained the budget in plain terms, and made the whole thing feel doable. It never felt overwhelming.”
- Sarah R., Sonoma Valley
“Our remodel was tricky with many historical details and a few surprise issues behind the walls. There seemed to always be a solution without turning it into a problem. The house looks great and seamless. We're very happy.”
- Randal M., Kenwood
