State License
STATE C-15CSLB
Flooring contractors in Ontario, California, must operate under the regulatory framework of the Contractors State License Board (CSLB). The primary requirement for any project exceeding $500 in total cost is the C-15 Flooring and Floor Covering license. This ensures that contractors meet state standards for professional conduct, financial responsibility, and safety.
In addition to state-level licensing, contractors must register with the City of Ontario to obtain a local business tax certificate. While many flooring tasks are considered cosmetic and exempt from building permits, any work involving structural subfloor repairs or fire-rated assemblies must be cleared through the Ontario Building Division to ensure compliance with local and state building codes.
