Building permits, zoning and septic rules in Lenawee County, Michigan

56Index Score / 100
#63 of 83 in Michigan

Lenawee County, Michigan requires a building permit for new construction, but the permit comes from the city, township or village where the parcel sits, not from one countywide office12. Lenawee County itself does not administer zoning; each municipality sets its own3. Septic permits for every address in the county, city or not, come from the Lenawee County Health Department, except large municipal systems such as Adrian's, which EGLE regulates4.

Do you need a building permit in Lenawee County, Michigan?

Yes. Before constructing a building or structure in Lenawee County, the owner or project representative must apply in writing to the appropriate enforcing agency; a permit is also required when a structure's use or occupancy changes1. Ordinary repairs are exempt, but structural changes, changes to required exits, and specified plumbing, electrical, mechanical or safety-related work are not ordinary repairs1. Lenawee County directs building, mechanical, electrical and plumbing questions to the city, township or village where the property sits11. The enforcing agency periodically inspects work performed under its building permit12. A new or altered building cannot be occupied until the code official issues a Certificate of Occupancy9.

Who issues building permits and zoning approval in Lenawee County?

There is no single permit contact identified for every Lenawee County parcel. The county tells applicants to contact their municipality for building, mechanical, electrical, plumbing, driveway and zoning questions11. The appropriate building enforcing agency may be the state, county or local government, depending on jurisdiction1. If you do not know which municipality contains the parcel, the county directs you to the Lenawee County Equalization Department11. The department can be reached at 517-264-4522 or at 301 N Main St, Old Courthouse 1st Floor, Adrian, MI 4922113. Ask the identified enforcing agency for its application, inspection sequence and building-permit fee before finalizing plans; the county environmental-health fee schedule covers well and septic services, not every local building fee14. Michigan's owner-builder licensing exemption applies when an individual builds on their own property for their own use and occupancy, but it does not waive permits, inspections, codes or zoning7.

Does Lenawee County, Michigan have zoning?

Lenawee County does not administer zoning; the county states that zoning is determined and maintained by the municipality in question3. That means zoning approval, setbacks and use rules come from the city, village or township that contains the parcel, and the rules and dimensional schedules may differ from one municipality to the next5. Michigan law lets counties, townships, cities and villages establish zoning districts, but that statewide framework does not identify the districts adopted for a particular parcel15. We could not confirm a single answer for setbacks, minimum lot size, minimum dwelling size, lot coverage or building height. Before buying, ask the relevant municipal zoning office for the parcel's zoning district, permitted uses, dimensional standards and any approval required for the proposed home or accessory buildings.

How do septic permits work in Lenawee County?

The Lenawee County Health Department has jurisdiction over on-site sewage systems handling up to 10,000 gallons of wastewater per day; EGLE handles large municipal systems, including the system serving the City of Adrian4. Obtain the applicable construction permit before installation, then have the system inspected and approved by the department before placing it in service166. A building with plumbing must connect to an available public sewer or an approved private sewage-disposal system17. The county evaluates soil permeability, seasonal high water table, available land area and separation from nearby water supplies during the site evaluation16. Only 5.1% of Lenawee County soils are rated without severe limits for a conventional drain field, so do not assume a preferred house site will support a conventional system10. The county publishes environmental-health fees for septic services14. Reach the Sewage Disposal Program at 517-264-521416.

Can you live in an RV or tiny home on your land in Lenawee County?

We could not confirm a countywide rule allowing RV occupancy or temporary camping on private land in Lenawee County. Ask the city, township or village where the parcel sits because zoning is set by each municipality rather than the county3. Michigan's campground rules cover sites offered for temporary living quarters for 5 or more recreational units, so they do not answer whether one RV may be occupied on a private parcel18. Michigan guidance says a tiny house cannot be treated as a recreational unit merely because it is built on wheels; applicable local zoning, building, electrical and plumbing approvals still apply, along with health-department approval for wells and septic systems where needed19.

Building a home in Lenawee County: the steps, in order

  1. Identify the parcel's city, township or village; the Lenawee County Equalization Department can help if you are unsure11.
  2. Ask that municipality for the zoning district, allowed use, setbacks and required zoning approval because local requirements vary20.
  3. Submit the building-permit application to the appropriate enforcing agency before construction1.
  4. Apply to the local health department before drilling a private well8.
  5. Obtain the appropriate septic construction permit and site evaluation before installation416.
  6. Schedule building and septic inspections with the agencies that issued the permits126.
  7. Complete the work, pay required fees, finalize the permits and request the Certificate of Occupancy before moving in9.

What to check before you buy land in Lenawee County

Start with jurisdiction: identify the city, township or village and obtain its parcel-specific zoning and building requirements2011. Test the proposed septic area early because only 5.1% of Lenawee County soils are rated without severe limits for a conventional drain field10. Confirm the approved water source; a private well requires a permit application before drilling8. Ask the municipality who controls driveway access for the parcel11. A driveway connecting to a state trunkline requires an MDOT permit in addition to the local building permit21. Check flood status early: new homes are prohibited in a regulated river, stream or drain floodway, and other regulated floodplain work may require EGLE approval22. Lenawee County's effective property-tax rate is about 1.3%, and the median annual property-tax bill is about $2,4122324.

Watch-outs

  • Lenawee County directs building and zoning questions to the parcel's city, township or village, and the building enforcing agency can vary by jurisdiction; septic and well permits stay with the Lenawee County Health Department111.
  • Michigan's owner-builder exemption concerns residential-builder licensing only; it does not waive building permits, inspections, codes, zoning or utility requirements7.

    • Before construction, a written building-permit application must be submitted to the appropriate enforcing agency.
    • A permit is also required when use or occupancy changes.
    • Ordinary repairs do not require a permit, but the stated structural, egress, plumbing, electrical, mechanical, and public-health/safety limitations apply.
