Does Jonesville, MI have zoning, and what does it mean for lots and setbacks?

Yes. Jonesville has its own zoning inside city limits, and the city, not Hillsdale County or a township, approves zoning permits1. The city manager serves as zoning administrator, with a planning commission and zoning board of appeals behind that office1.

Rules differ by district. In the R-1 residential district, lots need at least 20,000 square feet and 110 feet of width5. In R-2, the minimum is 9,500 square feet with public sewer and 15,000 square feet without it9. R-1 homes must have at least 1,200 square feet of floor area, or 780 square feet on the ground floor6.

R-1 setbacks are 30 feet in front10, and building height tops out at 25 feet or 2½ stories, though farm buildings may keep their usual heights11. Lot coverage in R-1 is capped at 25 percent12.

We could not confirm Jonesville's rules for tiny homes or RV living; ask City Hall13.

Do you need a building permit in Jonesville, and who issues it?

Yes. Building, electrical, plumbing and mechanical permits inside Jonesville are handled by the Hillsdale County building inspection office, not by city staff2. The city's own page says a zoning approval generally comes first2.

The city's page notes that some small projects, such as sheds, may not need a building permit but still need a zoning permit2. Michigan requires a written permit application to the appropriate enforcing agency before construction, and a permit is also required when a structure's use or occupancy changes14.

A complete zoning application includes a drawing showing distances to lot lines4. The Hillsdale County Inspection Department is at 33 McCollum St. in Hillsdale and takes calls at (517) 437-413015.

Who handles zoning and permits for a lot in Jonesville?

Two offices split the work. City Hall at (517) 849-2104 handles zoning approvals, and for most requests the zoning administrator can approve without a board hearing13. Typical zoning review runs 1 to 2 business days after a complete application4.

Driveway work that meets the city street or sidewalk needs approval from the zoning administrator16. Building, electrical, plumbing and mechanical permits go to the county inspection office2.

After construction, a new or altered building cannot be occupied until a Certificate of Occupancy is issued17. We could not confirm which office issues it inside city limits, so ask the county inspection office when you pull your building permit.

How do septic permits work in Jonesville?

Septic permits are not a city function. Installing an on-site sewage disposal system in Hillsdale County requires a permit from the Branch-Hillsdale-St. Joseph Community Health Agency, and the fee is due when you apply3. Well permits come from the same agency7.

Many lots inside the city may connect to public sewer, and Michigan requires buildings with plumbing to connect to a public sewer where one is available18. We could not confirm which Jonesville streets have city sewer or whether the city requires connection; ask City Hall before you rely on a septic system13.

For vacant land, the health agency offers site evaluations to judge whether a property suits a well and septic system19. Across Hillsdale County, only about 11.6% of soils rate as not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system20. Call the agency at 517-437-739519.

Can you live in an RV or tiny home in Jonesville?

We could not confirm either answer for Jonesville, so treat both as needing written approval before you buy. Michigan's statewide campground rules apply to sites offered to the public or an organization, not to a single RV on your own lot, so they do not answer this question21.

For tiny homes, Michigan's guidance says local zoning, building, electrical and plumbing permits and final approvals come from local authorities22. Any dwelling in the R-1 district must also meet the 1,200 square foot minimum floor area6. Ask the zoning administrator at City Hall, (517) 849-2104, before you commit13.

Building a home in Jonesville: the steps, in order

  1. Confirm your lot's zoning district and dimensions with City Hall, since lot size, home size and setbacks vary by district5.
  2. Get a site evaluation and well and septic permits from the health agency if public sewer or water does not serve the lot19.
  3. Apply for zoning approval from the city with a drawing showing distances to lot lines4.
  4. Apply to the Hillsdale County Inspection Department for building, electrical, plumbing and mechanical permits2.
  5. Build to the Michigan Building Code, effective April 9, 2025, with inspections during construction23.
  6. Request your Certificate of Occupancy once fees are paid and permits are finalized17.

What stays with Hillsdale County, and what to check before you buy in Jonesville

Septic, well and environmental health permits stay with the Branch-Hillsdale-St. Joseph Community Health Agency3. Building permits stay with the county inspection office2. Rules for land outside the city differ, so see the Hillsdale County page for unincorporated land.

Being an owner-builder exempts you from residential-builder licensing for your own home, but not from building permits or code24. A Michigan driveway onto a state trunkline highway needs a separate Michigan DOT permit25. Floodplain work along larger streams may need a state EGLE permit26.

Hillsdale County's effective property tax rate is about 1%, and the median property tax bill is $1,644 a year2728.

Watch-outs

  • Zoning approval usually comes before the building permit, and the two offices are different: City Hall for zoning, the Hillsdale County Inspection Department for building permits2.
  • We could not confirm Jonesville's rules on tiny homes, RV living, sewer connection or floodplain development; ask City Hall at (517) 849-2104 before you buy13.
  • Dimensional rules change by district, so a lot size or setback that applies in one residential district may not apply to your parcel9.
