Building permits, zoning and septic rules in Genesee County, Michigan
48Index Score / 100 #76 of 83 in Michigan
Building permits in Genesee County, Michigan come from the state, county or local enforcing agency assigned to the parcel, and Grand Blanc Township, for one, approves and inspects its own12. Zoning is set locally: Grand Blanc Township has its own zoning districts, and we could not confirm countywide zoning3. Septic permits where sewer is unavailable come from the Genesee County Health Department, not the township or city4.

Do you need a building permit in Genesee County, Michigan?
Yes. Before construction of a building or structure in Genesee County, the owner or the owner's representative must apply in writing to the appropriate enforcing agency; a permit is also required for a change in use or occupancy1. Ordinary repairs are exempt only when they do not involve the structural, egress, public-health or general-safety work identified by the state1. The Michigan Building Code applies statewide, while residential requirements are contained in the Michigan Residential Code11. Grand Blanc Township's Building Division approves permits and inspects permitted work within Grand Blanc Township, but buyers elsewhere must identify the state, county or local agency assigned to their parcel212.
Who issues building permits in Genesee County, and how do you reach them?
The correct building-permit office in Genesee County is the enforcing agency assigned to the parcel, which may be state, county or local; the Michigan Statewide Jurisdiction List identifies the assignment112. For land in Grand Blanc Township, contact the Grand Blanc Township Building Department at 810-424-2600, visit 5371 South Saginaw Road, or use its online permit portal13. Grand Blanc Township inspects the permitted work it approves under the Michigan Building Code2. Michigan's owner-builder licensing exemption covers a person erecting a residence on that person's property for personal use and occupancy, but it does not waive the building permit6. Grand Blanc Township's building permits and zoning do not cover septic: where sewer is unavailable, septic permits and well permits come from the Genesee County Health Department, whatever the township48.
Does Genesee County have zoning?
Grand Blanc Township has multiple zoning districts, each with its own permitted uses and standards for setbacks, density and height3. In Grand Blanc Township, the applicable setbacks depend on the parcel's zoning district, and the plot plan must show front, side and rear setbacks plus wetland and power-line setbacks where present14. We could not confirm whether Genesee County directly administers countywide zoning, so ask the township, city, village or county authority serving the parcel rather than applying Grand Blanc Township's rules elsewhere. Grand Blanc Township Planning & Zoning handles questions within that township15. Michigan's tiny-house guidance requires local zoning, building, electrical and plumbing permits and final approvals, including for a tiny house on wheels7.
How do septic permits work in Genesee County?
Where municipal sewer is unavailable, the Genesee County Health Department regulates onsite sewage through site evaluations, permits and inspections4. Vacant land goes through a perc test first and a septic-permit application second; a new residential permit costs $220 and is valid for one year from issuance1617. A licensed septic contractor, or the owner working under Environmental Health supervision, must install the system, and the department must inspect the tank and drainfield before backfilling18. The Health Department's septic installation certificate must be issued before occupancy, but that certificate approves the septic installation only and is not the building certificate of occupancy19. Only about 2% of Genesee County soils are rated without severe limitations for a conventional drain field, making the site evaluation a consequential early check20.
Can you live in an RV or tiny home on your land in Genesee County?
A tiny house in Genesee County needs local zoning, building, electrical and plumbing permits and final approvals, even when the house is built on wheels7. RV rules are set township by township. In Genesee Township, transient RV occupancy may not exceed 30 continuous days in any 120-day period unless the vehicle is connected to electrical service and approved sanitary facilities, in which case it may not exceed 90 days in a calendar year, and a temporary-use permit from the Zoning Administrator is required10. In Grand Blanc Township, RVs in residential districts are usually required to be parked behind or beside the house and must meet the front-yard setback21. We could not confirm a countywide rule for living in an ordinary RV, temporary camping, minimum dwelling size or tiny-home occupancy, so ask the zoning authority for the parcel before buying or moving onto the land. Any residence with sewage-generating fixtures must connect to an approved sewage-disposal system; roof drains, footing drains, stormwater pipes and water-softener discharge cannot connect to the septic system22. A new or altered building cannot be occupied until the code official issues a certificate of occupancy9.
Building a home in Genesee County: the steps, in order
Identify the parcel's building-code enforcing agency from the statewide jurisdiction assignment, then confirm zoning with the authority serving that parcel123.
If public sewer is unavailable, complete the county's perc-test process before applying for the septic permit516.
If the property needs a private residential well, submit the county application and scaled site plan before construction; the permit costs $200 and expires two years after issuance8.
Call MISS DIG 811 before applicable excavation, then apply to the appropriate enforcing agency for the building permit; an owner-builder exemption from builder licensing does not remove the permit requirement1716.
Complete building and septic inspections, including the septic inspection before the tank and drainfield are backfilled218.
Obtain the Health Department's septic installation certificate and the separate building certificate of occupancy before moving in199.
What to check before you buy land in Genesee County
Confirm the parcel's jurisdiction first because building-code enforcement and zoning standards depend on the assigned state, county or local authority1223. Check sewer availability and soils before treating a conventional septic system as feasible: only about 2% of Genesee County soils are rated without severe limits for a conventional drain field2420. If the parcel will use a private well, budget for the $200 residential permit, a scaled site plan, a satisfactory bacteria test and a completed pump record before the water supply enters service8. For Grand Blanc Township property, address requests and driveway permits go through the Genesee County Road Commission permit system, but the source does not establish the same requirement for every road frontage in the county25.
Watch-outs
A tiny house on wheels still needs full local zoning, building, electrical and plumbing approval in Michigan; it can't be treated as a recreational unit just because it has wheels7.
Grand Blanc Township is a verified local example, not the rule for every Genesee County parcel; use the statewide jurisdiction assignment and the parcel's zoning authority before applying21223.
Genesee County's septic and well fees vary by service, and electronic payments add a service fee, so verify the current total before submitting an application26.

county building authorityGeneral
Michigan counties serving as building-code enforcing agencies for residential construction in unincorporated areas, subject to the Statewide Jurisdiction List and local/state jurisdiction assignments.
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.
The Michigan Building Code and Michigan Residential Code govern construction; county enforcement applies only where the Statewide Jurisdiction List designates county jurisdiction.
“If COUNTY is indicated, that unit of government receives code enforcement services from a county enforcing agency.”
