Summary
Operating as a licensed plumbing contractor in Tempe requires compliance with both state and local regulations. At the state level, contractors must obtain an Arizona ROC Class C-36 license, which involves passing exams, demonstrating experience, and maintaining financial responsibility. Individual plumbers must also hold state licenses through the Department of Fire, Building & Life Safety. The licensing process typically takes 4-8 weeks and requires ongoing continuing education for renewals. Locally, the City of Tempe requires permits for most plumbing work, with applications processed through the Development Services Department. Contractors must also maintain substantial insurance coverage and bonding, with minimum requirements of $750,000 in general liability insurance. Success in this market depends on understanding both the regulatory framework and local building codes, as Tempe has specific requirements for water conservation and backflow prevention that contractors must follow.
