Lenawee County Plumbing Permit Requirements
In Lenawee County, Michigan, plumbing permit requirements are generally handled at the local municipal level. For properties in unincorporated areas, you will need to contact the specific township or municipality where the property is located, as they are responsible for issuing building, mechanical, electrical, and plumbing permits. Lenawee County itself, through its Drain Commissioner's office, handles permits related to drain crossings, soil erosion, and work within drain rights-of-way. The Lenawee County Health Department is the point of contact for public and private on-site sewage disposal systems and water information.
Generally, plumbing permits are required for new construction, additions, renovations that modify connections to municipal water and sewer systems, and major repairs or modifications to sewer and drain lines. Minor repairs, such as fixing a faucet or clearing a stoppage, typically do not require a permit, provided no existing piping or fixtures are altered. Homeowners may be able to obtain permits for work on their own primary residence, but contractors must hold the appropriate licenses and obtain permits in their company or licensed name.
The State of Michigan mandates that plumbing permits are issued to licensed plumbing contractors or homeowners performing their own work. Licensed contractors must designate a full-time, licensed master plumber to supervise the work. The Michigan Plumbing Code governs the design and installation of plumbing systems, and local enforcing agencies (municipalities, counties, or townships with building departments) ensure compliance.
- County-Level Jurisdiction: While Lenawee County has departments like the Drain Commissioner's Office and the Health Department that issue specific permits (e.g., for drains, sewage, water), the primary responsibility for general plumbing permits lies with individual municipalities within the county.
- Unincorporated Areas: For properties in unincorporated areas of Lenawee County, you must contact the specific township or municipality governing that area for plumbing permit requirements.
- State Requirements: Plumbing work must comply with the Michigan Plumbing Code. Permits are generally required for significant installations, replacements, or alterations to plumbing systems.

State Statutes and Adopted Plumbing Codes
The State of Michigan regulates plumbing installations through the Stille-DeRossett-Hale Single State Construction Code Act (Public Act 230 of 1972). Under this authority, the state has adopted the 2021 Michigan Plumbing Code, which is based on the 2021 edition of the International Plumbing Code (IPC) with specific Michigan amendments. This code became effective on March 12, 2024. For detached one- and two-family dwellings and townhouses not more than three stories high, the plumbing requirements are governed by the Michigan Residential Code.
Primary State Board and Agencies
The primary agency responsible for the administration and enforcement of plumbing codes and licensing in Michigan is the Department of Licensing and Regulatory Affairs (LARA), specifically through the Bureau of Construction Codes (BCC). Within the BCC, the Plumbing Section oversees inspections and code enforcement. Additionally, the State Plumbing Board, created by Public Act 733 of 2002, is responsible for making recommendations for plumbing code rules, licensing plumbers, and establishing regulations necessary for the enforcement of the act.
