Permits and licensing in Michigan

The Bureau of Construction Codes in the Department of Licensing and Regulatory Affairs (LARA) writes Michigan's plumbing code rules. Michigan law says only a licensed master plumber or journey-level plumber may do plumbing work, and a plumbing contractor must be licensed too. Minor repair work is an exception. Michigan law says plumbing work cannot start until the responsible plumbing contractor has a permit from the state or a local government that issues permits.

  • City of Grand Rapids: $52.00 plumbing application fee (1 inspection) plus $6.00 for 3/4" interior water distribution. For a house with 2 full baths and 11 fixtures, that comes to $58.

Michigan law lets a homeowner install plumbing in their own single-family home without a license, as long as they get a permit.

Age of Michigan's housing

Half of the housing units in Michigan were built before 1972, by the Census Bureau's ACS 2024 1-year count. 36% were built before 1960, when galvanized supply pipe was common. 21% were built from 1980 to 1999, the two Census decades that overlap the years polybutylene pipe was made. Age alone does not tell you what pipe a house has; a plumber or inspector can.
