Eaton County Plumbing Permit Requirements
Eaton County, Michigan, enforces plumbing permit requirements through its Department of Construction Codes. These regulations apply to most plumbing installations and modifications, ensuring compliance with the Michigan Plumbing Code. The county utilizes an online system (BSA) for permit applications and scheduling inspections.
Jurisdiction and Unincorporated Areas
Eaton County's Department of Construction Codes has jurisdiction over building and safety matters within the county, including unincorporated areas. For properties in unincorporated areas, residents and contractors must adhere to the county's permit requirements. While specific rules for unincorporated areas are not detailed separately, the general county regulations apply.
When Permits Are Required
A plumbing permit is generally required for:
- New plumbing installations.
- Replacement or modification of existing plumbing systems, including drain, waste, vent, and water distribution piping.
- Any work that alters a plumbing fixture or its connection to the system.
- Additions to existing plumbing systems.
- Installation or replacement of water heaters.
- Work on sewer and drain lines, including pipe replacements and sump pumps.
- Installation of backflow preventers.
Minor repairs, such as drain cleaning, faucet repair, or clog removal, may be exempt, but it is advisable to confirm with the county. For work extending three feet outside a home or business to the main sewer or water line, a separate Water & Sewer Permit from the local municipality (e.g., Grand Ledge) may be required before applying for a building permit.
Homeowner and Contractor Responsibilities
Homeowners can apply for permits and perform work on their own primary residence, provided they occupy or intend to occupy the dwelling. However, for commercial, industrial, or rental properties, a licensed plumbing contractor must apply for and perform the work. It is crucial to use only State of Michigan licensed contractors. The permit holder and property owner are responsible for understanding and complying with all applicable federal, state, and local laws, ordinances, and code requirements.
Plan Review
For new construction, alterations, repairs, expansions, additions, or modifications, plans and specifications prepared by or under the direct supervision of a licensed architect or engineer may be required. A plan review is necessary before a permit can be issued, unless the work is considered minor in nature by the building and plumbing officials, or if it pertains to one- and two-family dwellings under 3,500 square feet.
Inspections
Inspections are mandatory to ensure compliance with the Michigan Plumbing Code. Permit holders must arrange for and obtain all necessary inspections. Inspections can be requested by calling the Eaton County Construction Codes office at (517) 543-3004.
