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

Yes. Before constructing a building or structure in Ingham County, the owner or the owner's agent must submit a written building-permit application to the appropriate enforcing agency; a change in use or occupancy also requires a permit¹. Ordinary repairs are exempt, but structural, egress, plumbing, electrical, mechanical and public-safety work falls outside that exception¹⁰. The Michigan Building Code applies generally, while residential requirements are in the Michigan Residential Code⁸. The enforcing agency periodically inspects work performed under its building permit¹¹. A new or altered building cannot be occupied until the code official issues a certificate of occupancy⁷. Michigan's owner-builder licensing exemption covers a person building on their own property for their own use and occupancy, but applicable permits still remain necessary⁴.

Who issues building permits in Ingham County, and how do you reach them?

Building permits in Ingham County are issued by a state, county or local enforcing agency, so identify the jurisdiction before filing¹. Which agency applies depends on the township, city or village where the parcel sits¹². Ingham Township is one local example, not the office for the whole county: its packet says the building permit and certificate of zoning compliance follow soil-erosion, well-and-septic, driveway and township-zoning approvals¹³. Whichever agency issues the building permit, septic permits and well permits stay with the Ingham County Health Department, and driveway permits for county roads with the Ingham County Road Department¹⁴¹⁵. If the Michigan LARA Inspections Division is the enforcing agency, it offers building, electrical, mechanical and plumbing permits online or by mail¹⁶.

Does Ingham County have zoning, and what does that mean for RVs, tiny homes and setbacks?

Ingham County does not run one zoning ordinance for all land. Zoning in Ingham County is set by each township, city or village, and the county's own ordinance expects locally administered zoning to apply². Michigan law allows counties, townships, cities and villages to establish zoning districts, so the districts and rules must be read in the ordinance for the jurisdiction covering the parcel¹⁷. We could not confirm a consolidated district map, so ask the applicable township, city or village about minimum lot size, setbacks, building height, lot coverage, manufactured homes and accessory dwellings. Ingham Township is one example: its building packet requires a township zoning permit before the building permit and says its certificate expires one year from the date issued¹³. A proposed tiny house still needs applicable local zoning, building, electrical and plumbing permits and final approvals, even when built on wheels¹⁸.

How do septic permits work in Ingham County?

The Ingham County Health Officer must issue a septic permit before anyone constructs, alters or extends a private or semi-public onsite sewage system, and this applies countywide, including inside cities and villages³. A septic permit is valid for 2 years and can move to a new owner only with Health Officer approval¹⁹. Published county fees include $1,000 for a new or repair septic-and-drain-field permit, $455 for septic-tank-only work, $495 for a well permit and $1,355 for a combined well-and-septic permit²⁰. Ingham County also requires inspection and approval of onsite sewage-treatment and water-well systems before a home-ownership transfer²¹. A septic system cannot be installed in a floodplain or wetland without Health Officer approval²². Only 1.2% of county soils rate without severe limits for a conventional septic drain field, so arrange the county's land evaluation before treating a parcel as buildable⁹.

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

We could not confirm a countywide rule allowing long-term RV occupancy, temporary camping or tiny-home occupancy on private land in Ingham County, so ask the township, city or village zoning office that covers the parcel before buying or moving a unit onto it. Michigan guidance says a tiny house proposed as a resort cabin is distinct from a recreational unit even if it is built on wheels, and it requires applicable local zoning, building, electrical and plumbing permits and final approvals¹⁸. Sanitary sewage from toilets, sinks, showers, washing machines and dishwashers must go to a municipal sanitary sewer or an onsite septic system²³. The county Health Department handles the onsite septic approval in Ingham County¹⁴.

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

1. Identify the township, city or village covering the parcel and check its zoning district, because actual district rules are local¹⁷.

1. Ask which state, county or local agency enforces the building code, then submit the written building-permit application there¹.

1. Apply to the Ingham County Health Department before constructing, altering or extending an onsite sewage system; the published septic permit fee is $1,000³²⁴.

1. Check soil-erosion and access approvals for the site; Ingham Township's sequence calls for county Drain Commission and Road Department approvals before township zoning sign-off¹³. Access within a state-highway right-of-way requires an MDOT driveway permit²⁵.

1. If the site lies in a qualifying floodplain, obtain the required state permit before altering or occupying it; new residential construction is prohibited in the floodway²⁶.

1. Complete periodic inspections for permitted construction and obtain the certificate of occupancy before using a new or altered building¹¹⁷.

What to check before you buy land in Ingham County

Typical home value in Ingham County is about $232,573, while farmland value is about $5,227 per acre²⁷²⁸. Population density is about 512 people per square mile, and the nearest city of 100,000 or more is about 12 miles from the county's center²⁹³⁰. About 34% of the county is wooded, and nearly 100% of its land has a slope of 15% or less³¹³². The sharper due-diligence issue is septic suitability: only 1.2% of soils rate without severe limits for a conventional drain field, and the county offers a vacant-land evaluation for $500⁹³³. Subdivision plats are regulated under Michigan's Land Division Act, and county road, drain and health approvals precede County Plat Board action⁶⁵. Before closing, confirm local zoning, septic and well feasibility, road access and floodplain constraints^17342526.

Watch-outs

• Do not assume the Ingham Township office covers the whole county; Michigan permit jurisdiction may be state, county or local, and zoning districts are set by the applicable local government¹²¹⁷.
• The owner-builder exemption is from residential-builder licensing for a person building on their own property for their own use and occupancy; it does not waive building permits or other construction requirements⁴.
• We could not confirm a countywide rule for full-time RV living, temporary camping or minimum dwelling size; ask the applicable township, city or village zoning office before buying or placing a unit¹⁷.
