Failure to adhere to these state-wide mandates can result in significant project delays and professional liability.
Locally, the City of San Rafael requires contractors to secure a municipal business license and obtain specific mechanical permits for equipment replacement or new installations. Contractors should prioritize timely permit filing and inspection scheduling through the San Rafael Building Division to ensure project compliance and avoid costly enforcement actions or stop-work orders.
