Building permits, zoning and land rules in Marquette County, Michigan

Yes. Marquette County issues building permits throughout the county for new construction, additions, alterations, remodeling, demolition or removal, changes of use, and moving buildings¹. Separate electrical, plumbing, and mechanical permits are required, and the building permit does not include them¹. The county enforces the Michigan Building Code, with one- and two-family dwelling work governed by the Michigan Residential Code⁷. A building incidental to agricultural use of the land is exempt from the building-permit requirement if it is not used in retail trade, though other permits and rules may still apply⁸. An owner building a home for the owner's own use and occupancy may qualify for a builder-licensing exemption, but the county building permit is still required⁵.

Marquette County Building Codes is in the Resource Management/Development Department at the Marquette County Courthouse, 234 West Baraga Ave, Marquette, MI 49855; call (906) 225-8180 or email buildingcodes@mqtco.org⁹. Submit the application with written zoning approval, plans, the legal description, applicable water and septic approvals, a soil-erosion permit where required, and contractor information¹. Pay the permit fee and wait for issuance before starting construction¹. The county no longer administers plumbing and mechanical permits, so ask Building Codes which state permits apply to the project⁹. The permit holder schedules county inspections by phone; listed stages include footing forms, foundation, framing and rough electrical, and a final inspection before occupancy¹⁰. A new or altered building cannot be occupied until the code official issues a certificate of occupancy after work and permits are finalized¹¹.

The township or city covering a Marquette County parcel enforces its own zoning ordinance and supplies written approval before a county building permit can issue¹. The county publishes local contacts and identifies Ewing and Turin townships as requiring no zoning approval, but it does not publish one district schedule for every parcel¹². We could not confirm whether a separate countywide zoning ordinance applies in any unincorporated area, so ask the parcel's township and Marquette County Building Codes before relying on an apparent gap. Minimum dwelling size, lot size, setbacks, lot coverage, temporary camping, manufactured homes, and accessory dwellings can vary with the local ordinance¹. Private subdivision covenants may impose additional rules on building size, placement, or construction features, and government agencies do not enforce those covenants¹.

The Marquette County Health Department administers onsite sewage rules throughout Marquette County². A facility generating sanitary sewage must connect to an available sewer; if no qualifying sewer is available, it must use an approved onsite treatment and disposal system, and a habitable building cannot receive its building permit first². Every permitted septic installation needs final inspection and approval before use, and new components cannot be covered before inspection or authorization². Only 4.4% of county soils lack severe limitations for a conventional drain field, so test feasibility before fixing the house location⁶. A privy may be permitted but cannot replace septic for a structure with pressurized plumbing or water-carried sewage, and floodplain, soil, tank, and separation conditions apply². Contact Environmental Health at (906) 475-4195 or visit 184 U.S. 41 East, Negaunee, MI 49866¹³.

Marquette County imposes no county zoning restriction on temporary camping in unincorporated areas, but the applicable township and other health, septic, floodplain, access, and building rules still matter³. We could not confirm a countywide answer for long-term residential RV occupancy, so ask the township or city that governs the parcel. Inside the City of Marquette, an RV designed for occupancy of 14 days or less cannot be used as a dwelling in residential districts except in specified locations or emergencies¹⁴. Tiny-home rules vary locally: Charter Township of Marquette requires a special land-use permit, county building permit, and county Health Department approval, plus compliant water, sewer, and parking⁴. In Marquette Township, a mobile-home park requires special-use approval, while temporary shelter in a mobile home is limited to disaster-related replacement or rehabilitation under township approval⁴.

1. Identify the township or city and obtain written zoning approval before applying for the county building permit¹.

1. Secure Health Department approval for a private well and onsite sewage system, or approval for public water and sewer, as applicable¹.

1. Prepare the plans, legal description, applicable soil-erosion permit, and contractor information¹.

1. Ask the Road Commission whether the driveway needs a permit; its applicants use Oxcart, and it publishes a permit fee schedule^1,15.

1. Obtain any wetlands or airport approval that applies to the site¹.

1. Submit the county application, pay the permit fee, and wait for issuance before starting work¹.

1. Schedule required inspections, then obtain the certificate of occupancy before using the completed building^10,11.

Confirm the parcel's township or city first, because Marquette County does not supply one zoning district schedule for every property¹². Test septic feasibility early because only 4.4% of county soils lack severe limits for a conventional drain field⁶. Ask which agency controls the road: a driveway permit may be required, County Road Commission applicants use Oxcart, and access to a state trunkline requires an MDOT permit^1,15,16. A proposed subdivision within an established county drainage district needs Drain Commissioner review, and review can also apply elsewhere when the municipality requests it¹⁷. Tall structures can trigger state review, including structures over 200 feet and certain proposals near airports¹⁸. Check private subdivision covenants separately because zoning approval does not resolve privately imposed restrictions¹.
