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

Kalamazoo County, Michigan requires a building-permit application to the appropriate enforcing agency before construction where Michigan's construction code applies; a change in use or occupancy also requires a permit¹. Ordinary repairs are exempt, but structural changes, changes affecting exits, and specified plumbing, electrical or mechanical work fall outside that exemption¹. Nonresidential work follows the Michigan Building Code, while one- and two-family residential work follows the Michigan Residential Code⁴. An owner erecting a residential or combined residential-commercial structure on the owner's property for the owner's own use and occupancy qualifies for a residential-builder licensing exemption; required building permits and inspections remain applicable⁷. A new or altered building cannot be occupied until the code official issues a Certificate of Occupancy⁶.

Kalamazoo County does not administer building inspections countywide; local governments handle inspections, sometimes through regional authorities². Galesburg, Parchment and the Village of Schoolcraft have local building-permit requirements^8,9,10. Septic permitting remains with Kalamazoo County Environmental Health where municipal sewer is unavailable³. KABA serves Comstock, Kalamazoo and Richland townships and Parchment; AGS serves Charleston and Ross townships and Schoolcraft village². Use the county's municipal contact directory to reach the appropriate local government for authoritative building-code information². The enforcing agency may instead be the state, so confirm jurisdiction before filing¹.

Unincorporated Kalamazoo County has no county zoning ordinance; each city, village and township manages its own zoning ordinance and map². Galesburg, Parchment, the Village of Schoolcraft, the Village of Vicksburg and the Village of Richland have their own zoning^{9,11,12,13,14}. County Environmental Health still handles onsite sewage permits where municipal sewer is unavailable³. The county sets no zoning minimum dwelling size, minimum lot size or setbacks for unincorporated land, but locally administered standards may apply². Manufactured homes and accessory dwellings likewise face no county zoning restriction, while municipal zoning, building-code and health requirements may still control the parcel².

Kalamazoo County Environmental Health requires a permit before an onsite sewage treatment system is installed where municipal wastewater service is unavailable³. The published private sewage permit fee is $480 and includes four site visits¹⁵. After permitting, a currently registered company or the property owner may install the system³. Only 6% of county soils rate without severe limits for a conventional septic drain field, so do not assume a standard system will work before a site review⁵. The county's vacant-parcel evaluation assesses parcel size, topography, soils and depth to high groundwater, and requires an on-site excavation with Environmental Health present¹⁶. Environmental Health also reviews land divisions that will use onsite water or septic systems³. In Galesburg, private sewage facilities where public sewer is available require written authority from the health officer and city council and must meet state and county health standards¹⁷.

Kalamazoo County zoning does not restrict RV occupancy, temporary camping or tiny-home occupancy on private land in unincorporated county areas because the county has no zoning ordinance². This is not blanket permission: city, village or township zoning and building-code rules, plus health, septic and floodplain requirements, may still apply². Ask the applicable municipal zoning office whether the parcel allows the proposed use and temporary occupancy during construction². Where municipal wastewater service is unavailable, an onsite sewage system needs a county permit before installation³. A tiny house may also require local zoning, building, electrical and plumbing approvals¹⁸.

1. Identify the parcel's city, village or township and contact its zoning and building-inspection office or contracted authority².
2. Ask the local zoning office for the parcel's district, setbacks, dwelling standards and temporary-occupancy rules².
3. Where public sewer is unavailable, obtain the county septic construction permit before a building permit for a building with plumbing can issue; Pavilion Township's applicable sanitary code states this requirement¹⁹.
4. Submit the building-permit application to the appropriate enforcing agency before construction begins, including when using the owner-builder licensing exemption^1,7.
5. Check Drain Commissioner requirements for drain work and soil disturbance; agricultural exemptions cover plowing, tilling for crop production and harvesting crops^20,21.
6. Arrange code inspections and obtain a Certificate of Occupancy before occupying the home^6,22.

Start with a vacant-parcel well and septic evaluation: only 6% of Kalamazoo County soils rate without severe limits for a conventional drain field⁵. The county evaluation assesses parcel size, topography, soils and high groundwater¹⁶. Environmental Health review also applies to a land division that will use onsite water or septic³. A private well pumping less than 70 gallons per minute needs a county permit, and the published fee is $300^15,23. Confirm zoning with the city, village or township². Check for county drains because a crossing, modification or discharge requires a Drain Commissioner permit²⁰. The median property-tax bill is about $3,378 per year at an effective rate near 1.5%⁵.
