Corona is home to 109 licensed plumbing contractors (C-36, CSLB September 2026) — #22 in California, about 8% of the 1,447 contractor licenses based here.
Nearby in Riverside County: Riverside (207), Murrieta (78), Temecula (78), Menifee (58).
46% of Corona's C-36 licensees hold more than one classification — most often B General Building Contractor (30%), C-20 Warm-Air Heating, Ventilating and Air-Conditioning Contractor (18%). Extra classifications can change how carriers rate your general liability and workers' comp, so list every license class when you quote.
Business structure: 30% sole owners, 65% corporations, 5% LLCs; median time licensed 10.0 years.
For plumbers, underwriters focus first on: water damage from failed fittings, supply lines and water heaters; and mold claims that follow slow leaks. See the full coverage guide for plumbing contractors for limits, endorsements and workers' comp rules.
