Summary
Milwaukee requires a permit from the commissioner of city development before any plumbing work, issued only to licensed, registered and bonded plumbers under the city's adopted state plumbing code.
ISSUANCE. No permit for plumbing shall be issued by the commissioner to any person not duly licensed, registered and bonded. Permits issued shall be subject to the rules and regulations of the commissioner, and it shall be unlawful to do any plumbing without a permit with the exception of work as regulated in sub. 3 and work exempted under s. 200-24-1.5.
Full Breakdown
Milwaukee adopts Wisconsin's plumbing statutes and administrative code (chs. SPS 81-87) as part of its own code, then layers on city permitting: under § 225-3, the commissioner issues plumbing permits only to licensed, registered and bonded plumbers, and it's unlawful to do any plumbing work without one. A narrow one-family-dwelling exception lets an owner-occupant do plumbing in their own home if they still pull a permit and follow the chapter's rules. Working without a permit, or continuing after a stop-work order, draws penalties under § 200-19.
Violations & Fines
Doing plumbing work without a permit, or without being a licensed, registered, bonded plumber, is unlawful and subject to penalty under § 200-19; ignoring a stop-work order carries the same penalty.
