They serve as the primary point of accountability, overseeing the entire project and coordinating specialized trades such as plumbing and electrical to ensure timely completion and compliance with building codes.
The California Contractors State License Board (CSLB) requires anyone charging $500 or more for materials and labor to hold a valid license. Operating without an active license can result in steep penalties and may render your business contracts unenforceable.
