Building permits, zoning and land rules in Eaton County, Michigan

Eaton County, Michigan requires a building permit before construction and when a building's use or occupancy changes; apply to the appropriate state, county or local enforcing agency¹. Within its listed jurisdiction, Eaton County enforces the 2015 Michigan Residential Code for one- and two-family homes and the 2021 Michigan Building Code for commercial and industrial buildings⁵. Ordinary repairs are exempt only if they do not affect structural supports, required egress or public-health and safety systems¹. Charlotte issues city building permits⁸. Grand Ledge requires a city Zoning & DPS Referral Form before the county building-permit application for new construction and specified alterations; Bellevue village generally requires village zoning approval before construction, with construction codes enforced by Eaton County^9,10. Private septic systems remain subject to Barry-Eaton District Health Department review and septic permits³.

The Eaton County Department of Construction Codes inspects work and verifies code compliance within its listed jurisdiction⁶. Its office is at 1045 Independence Boulevard, Room 150, Charlotte, MI 48813; call 517-543-3004 or email ConstructionCode@eatoncounty.org¹¹. Eaton County accepts construction-code applications through BS&A Online, with staff assistance and public computers available; online card payment follows staff review¹². To request a county inspection, call 517-543-3004 and leave your name, phone number, permit number or job-site address, and inspection type⁶. County inspection hours are Monday through Friday, 9:00 a.m. to 4:00 p.m., excluding holidays⁶. Check the county jurisdiction list before applying because some communities administer construction codes locally⁵.

Eaton County repealed county zoning in unincorporated areas effective June 30, 2026; township and municipal zoning authority remains². Charlotte, Grand Ledge, Olivet, Bellevue village and Dimondale village have their own zoning^{10,13,14,15,16}. Private septic review remains with Barry-Eaton District Health Department, including inside Olivet and Dimondale^3,17. County zoning sets no minimum dwelling size, minimum lot size, setbacks, lot-coverage limit or building-height limit in unincorporated Eaton County². Ask the parcel's township, village or city for its current zoning map and ordinance; local zoning, building codes, septic separations, road requirements and floodplain restrictions may still constrain development².

The Barry-Eaton District Health Department evaluates Eaton County sites, issues on-site sewage permits and performs final reviews where municipal wastewater service is unavailable³. A site evaluation comes first; if the parcel can support development, the applicant submits the sewage-system application and fee before a sanitarian authorizes construction³. After installation, the owner or contractor must notify the department; the system can be covered after final approval and an approved tag³. Only 0.2% of Eaton County soils are rated without severe limits for a conventional drain field, so obtain the evaluation before fixing the house location or purchase budget¹⁸. The Eaton County health office is at 1033 Health Care Dr., Charlotte, MI 48813, and its phone is 517-543-2430³.

We could not confirm a countywide right to live in an RV on private land in Eaton County; ask the parcel's local government about RV occupancy, parking, utilities and time limits because the county zoning repeal left local zoning authority intact². Eaton County Parks rules do not answer the private-land question: on property administered by the Parks and Recreation Commission, camping is allowed only in designated areas with a written permit¹⁹. A tiny home is not automatically exempt from approvals: Michigan guidance for tiny houses used as resort cabins requires applicable local zoning, building, electrical and plumbing permits and final approvals, along with health-department approvals for wells and septic systems²⁰. County zoning itself sets no minimum dwelling size, but local-government rules and building-code minimums may still apply².

1. Identify the township, village or city and obtain its zoning rules because Eaton County no longer administers county zoning².

1. Use the county jurisdiction list to determine whether Eaton County Construction Codes or another agency enforces codes for the parcel²¹.

1. If municipal sewer is unavailable, arrange the health department's septic evaluation; a private well also needs a site evaluation and permit^3,4.

1. Confirm driveway access with the Eaton County Road Commission for a land division entering a county road, or with MDOT for a state highway²².

1. Submit the building-permit application to the proper enforcing agency before construction; Eaton County accepts applications through BS&A Online where it has jurisdiction^1,12.

1. In Eaton County Construction Codes' jurisdiction, complete the required inspections and obtain the Certificate of Occupancy before permanently occupying the home; well and septic approvals are required when those systems serve the home, and permanent electrical service needs inspection and approval before energizing^3,6,23.

Confirm local zoning and code jurisdiction first because the county zoning repeal does not answer what a township, village or city allows². Test septic feasibility early because only 0.2% of county soils lack severe limits for a conventional drain field, and budget separately for the required well evaluation, permit, final inspection and water sampling if the parcel needs a well^4,18. For a land division entering a county road, ask the Eaton County Road Commission whether a driveway can be established; MDOT handles access from a state highway²². Michigan requires EGLE approval for regulated river, stream or drain floodplain work and prohibits new residential construction in the floodway; ask EGLE and the parcel's local government about the proposed building site²⁴.
