State License
STATE C-33Painting & Decorating
Painting contractors operating in Ontario, California, must navigate both state-level licensing and local municipal requirements. The Contractors State License Board (CSLB) governs the C-33 trade license, which is mandatory for any project exceeding $500. Compliance involves maintaining a $25,000 bond, securing workers' compensation if employees are present, and adhering to EPA standards for lead-based paint in older structures.
At the local level, contractors must register with the City of Ontario to obtain a business license. While most residential painting does not require a building permit, contractors should always confirm project-specific requirements with the Ontario Building Division, especially for commercial properties or exterior work that may impact local zoning or environmental standards.
Compliance is hierarchical; state license is the foundation, city registration is the operational requirement.
