About Us
About Nine County Builders
Nine County Builders brings accountable field execution to commercial, multifamily, prevailing wage and public works construction across Northern California.
Our Company
Built to Be Accountable.
Nine County Builders is a Bay Area general contractor serving commercial, multifamily, and public-sector clients throughout Northern California.
We built NCB around a simple idea: construction should be straightforward. Clear scopes. Realistic schedules. Responsive communication. And accountability from bid through completion.
Our team brings experience across commercial improvements, multifamily capital projects, public works, prevailing-wage projects, and occupied properties. That experience gives us an understanding of what owners, property managers, and public agencies expect from a contractor working in active environments.
We take a hands-on approach to every project. The person estimating your project stays involved throughout execution, creating continuity and accountability from the initial bid through project completion.
