2024 Winter Inspector Code Updates
Wisconsin’s regional inspector associations, in cooperation with the Wisconsin Code Officials Alliance and the Wisconsin Department of Safety & Professional Services, are offering virtual and in-person training sessions in early 2024 for Wisconsin’s Electrical Code, Uniform Dwelling Code, Plumbing Code, and Commercial Building Code.  These courses can provide continuing education credits for Industry Services inspection and Dwelling Contractor Qualifier (DCQ) credentials.  Fire inspectors, designers, contractors, and others with an interest in Wisconsin’s codes may also benefit from the programs.
