Oakland County Plumbing Permit Requirements
In Oakland County, Michigan, plumbing permit requirements are generally governed by the state's plumbing code, with local enforcement by municipalities and townships. While Oakland County itself has a Building Safety Division, its primary role appears to be focused on the security and maintenance of county facilities rather than direct oversight of individual property permits.
For properties within unincorporated areas, the specific township or municipality where the property is located will typically handle building and permit applications, including those for plumbing. For example, Oakland Township has its own Building and Code Enforcement Department that manages plumbing permit applications and enforces the Michigan Plumbing Code.
Key aspects of plumbing permit requirements in Michigan, which would apply to Oakland County, include:
- Permit Necessity: Permits are generally required for most plumbing installations and modifications, including new installations, system replacements, additions, and alterations affecting supply, drainage, or venting.
- Exemptions: Minor repairs involving only the working parts of a faucet or valve, or clearing stoppages, typically do not require a permit, provided no existing piping or fixtures are altered.
- Who Can Apply: Permits can be obtained by a licensed plumbing contractor or, in most cases, by a homeowner for their own primary residence. Commercial, rental, or multi-family properties require a licensed contractor.
- Application Process: Applications typically include project details, property information, contractor license numbers, and potentially plan documents for complex projects. Many municipalities offer online, in-person, or mail submission options.
- Inspections: Plumbing work must be inspected and approved by the local enforcing agency at various stages (e.g., rough-in, final inspection) before being concealed or put into operation.
- Code Compliance: All installations must conform to the Michigan Plumbing Code and the Michigan Uniform Energy Code.
- Permit Validity: Permits are generally valid as long as work is progressing, with inspections being requested and conducted. They can expire if work is not commenced or is suspended for a specified period.
Rules for Properties in Unincorporated Areas
Properties in unincorporated areas of Oakland County fall under the jurisdiction of the specific township or municipality they are located within for building and plumbing permit requirements. These local governments are responsible for enforcing state building codes and issuing permits. For instance, Oakland Township has a dedicated Building Department that handles plumbing permit applications and inspections, ensuring compliance with the Michigan Plumbing Code.
It is crucial for property owners in unincorporated areas to identify the correct local authority (township or city) responsible for building permits and to consult their specific requirements, as these can vary. The Michigan Department of Licensing and Regulatory Affairs (LARA) provides resources to help identify the appropriate enforcing agency.

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.
