Do you need a building permit in St. Joseph County, Michigan?

A St. Joseph County property owner must apply for a building permit before constructing a building or structure, and a permit is also required when a structure's use or occupancy changes1. Ordinary repairs may be exempt, but that exception does not cover work that crosses the cited structural, egress, utility, electrical, mechanical, public-health or safety limits1. Construction is governed by the Michigan Building Code and Michigan Residential Code10. A new or altered building cannot be used or occupied until the code official issues a Certificate of Occupancy after completion, final permits and payment of fees11.

Who is the building department in St. Joseph County, and how do you reach them?

St. Joseph County has no general county building-code department; the appropriate enforcing agency may be a local office or the state, depending on the parcel's jurisdiction21. Identify the township, city or village containing the parcel, then confirm its assigned building official before filing. In Park Township, the Building Official can be reached at 269-816-4951, 62484 Kuhlmeyer Rd, Centreville, MI 4903212. Park Township zoning questions go to the Zoning Administrator at (269) 386-1110, P.O. Box 30, Colon, MI 4904013. Those Park Township contacts should not be assumed to serve land elsewhere in St. Joseph County5.

Does St. Joseph County have zoning?

Land-use zoning in St. Joseph County is administered at the township level rather than through one confirmed countywide ordinance; Park Township, for example, has adopted its own zoning ordinance5. Michigan law provides a framework for counties, townships, cities and villages to establish zoning districts, but the actual districts and rules come from the applicable local ordinance14. Ask the township, city or village zoning office about the parcel's allowed uses, setbacks, minimum dwelling size, accessory dwellings and lot coverage. Countywide answers for those details could not be confirmed because the applicable standards vary by local jurisdiction5.

How do septic and well permits work in St. Joseph County?

The Branch-Hillsdale-St. Joseph Community Health Agency administers onsite sewage rules throughout St. Joseph County, including its cities, villages and townships3. Obtain the sewage-disposal permit before constructing, repairing, enlarging or relocating a septic facility; for a new building served by septic, that approval must come before the local construction permit6. The application may require site maps, soil analysis, test borings, groundwater and flood elevations, nearby wells and detailed system plans6. The listed residential fees are $235 for sewage and $215 for a well, with other fees differing9. Only about 3.1% of county soils have no severe limitation for a conventional drain field, so settle septic feasibility early15.

Can you live in an RV or tiny home on your land in St. Joseph County?

Michigan treats a tiny house as distinct from a recreational vehicle even when the tiny house is built on wheels16. A tiny house needs zoning, building, electrical and plumbing permits and final approvals from the authorities serving the parcel, plus health-department approval for a well or septic system when applicable16. St. Joseph County zoning is administered locally, so ask the applicable township, city or village whether its ordinance permits the proposed tiny-home use5. We could not confirm a countywide rule for long-term RV living or temporary camping; ask that same zoning office before buying or occupying land for either use.

Building a home in St. Joseph County: the steps, in order

  1. Identify the township, city or village containing the parcel, then confirm the state or local enforcing agency assigned to issue its building permits21.
  2. Ask the applicable zoning office which district covers the parcel and whether the proposed home and accessory uses are allowed5.
  3. Apply to the health agency first if the project needs septic service; septic approval must precede the construction permit for a new building served by an onsite system6.
  4. Obtain the required well permit before installing an onsite water-supply system4.
  5. Submit the building-permit application with construction documents; the building official may waive those documents when the application description is enough to determine compliance17.
  6. Request the Certificate of Occupancy after completing the work, finalizing permits and paying fees11.

What to check before you buy land in St. Joseph County

Confirm the parcel's local jurisdiction and zoning district before buying because zoning and permit administration vary across St. Joseph County52. Test septic feasibility early: only about 3.1% of county soils have no severe limitation for a conventional drain field, and the health agency may require soil analysis, test borings, groundwater and flood elevations, and nearby-well information156. If planned non-agricultural earth changes cover one acre or more within 500 feet of a watercourse or lake, contact the Drain Commissioner about soil-erosion oversight18. Typical carrying costs include a 1.1% effective property-tax rate, a $1,867 median annual tax bill and a $1,204 typical annual home-insurance premium192021.

Watch-outs

  • St. Joseph County has no general county building-code department; confirm the state or local enforcing agency assigned to the parcel before applying21.
  • A new building served by septic needs health-agency approval before the construction permit can issue6.
  • Only about 3.1% of St. Joseph County's soils carry no severe limitation for a conventional septic drain field, so plan for a site evaluation before you assume a standard system will work15.
