Livingston County, Michigan septic permits and requirements

Michigan onsite-wastewater framework

Michigan EGLE states that onsite wastewater management is a required local-health-department service under the Michigan Public Health Code. Local health departments carry out ordinary onsite permitting and review while EGLE provides oversight, technical support, and review for certain larger or specialized systems.

Confirm project scope before construction

Local sanitary codes, sewer availability, wastewater flow, commercial use, property additions, replacement work, and alternative or engineered systems can change the approval path. Use the current county instructions and any applicable EGLE review before excavation or installation.

County Environmental Health administers septic permits and inspections

Livingston County states that septic systems must be permitted and installed under the Livingston County Sanitary Code and that Environmental Health Specialists conduct installation inspections and investigate failing-system complaints.

An approved soil evaluation comes before the septic permit

Livingston County requires a soil evaluation to be completed and approved before a septic permit application can be submitted. The issued soil evaluation contains site-specific requirements used for the permit.

Permit applications require parcel and site documentation

For new construction, the county lists a permanent street address, certified survey/legal description, accurate plot plan, applicable fees, and other project approvals among the materials used in the well/septic and building-permit sequence.

Construction changes require county approval and final septic approval

The septic contractor schedules the inspections listed on the permit. Livingston County states that changes from the approved plans must be approved by Environmental Health before excavation or construction, and a completed permit is forwarded to the building department after the septic inspections so the building department can proceed with Certificate of Occupancy review.

County septic permits have a one-year construction window

Livingston County states that sewage/well permits provide one year from issuance to complete construction. After that, the permit must be rewritten and a fee assessed; changes requiring another site visit can add a fee.

Additions and property modifications require site review

Livingston County requires a site review for additions or modifications on properties served by well or septic, including examples such as enclosed decks, pole barns, home additions, garages and pools.

No county point-of-sale septic inspection program

Livingston County explicitly states that it does not have a point-of-sale program and does not perform well/septic inspections merely because property ownership changes. Existing records can still be searched, and new or replacement work remains subject to county permitting.
