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

Yes. The Marquette County Resource Management/Development Department issues building permits for all of Marquette County, and permits are required for new construction, additions, alterations, remodeling, new or replacement plumbing, mechanical, or electrical systems, demolition or removal, changing an existing use, and moving any building, including a mobile home⁴¹. Before the county can issue that permit, you need written zoning approval from the township or city where your land sits, since the county itself sets no zoning rules⁵. Well or septic approval from the county Health Department's Division of Environmental Health is required where applicable, and a soil erosion permit is required separately if disturbed land is within 500 feet of a lake or stream or more than one acre is disturbed⁴. A permit fee must be paid before issuance, and construction may not start until the permit is in hand; starting work first triggers a $300 administrative fee on top of normal costs¹⁴. Once issued, a permit becomes invalid if work doesn't start within 180 days, or if it's suspended or abandoned for 180 days after starting¹⁴.

Who is the Marquette County building department, and how do you reach them?

Marquette County Building Codes, part of the Resource Management/Development Department, is based at the Marquette County Courthouse, 234 West Baraga Ave, Marquette, MI 49855, reachable at (906) 225-8180 or [email protected]¹⁵. As of March 9, 2026, the county no longer administers plumbing and mechanical permits directly; those now go through the State of Michigan, while the county's own staff still handle building and electrical permits, plan review, and inspections¹⁵. Permits can be applied for online through the state's Accela portal, by email, in person, or by mail¹⁵. For questions about your specific project, the county's own guidance is to speak directly with an inspector rather than the front-desk staff, since office staff can't answer technical code questions¹⁵.

Does Marquette County have zoning?

No, not at the county level. Marquette County does not have a zoning ordinance, and the county's own Local Zoning Analysis confirms this directly: townships and cities enforce their own zoning ordinances instead, and written zoning approval must come from them before a county building permit can be issued⁹⁵. Because the county sets no rules of its own, there is no countywide minimum lot size, no minimum dwelling size, no setback schedule, and no maximum lot coverage; all of these depend entirely on the specific township or city where your parcel sits¹⁶¹⁰¹¹. The county's planning commission reviews local plans for consistency with the County Master Plan but has no zoning authority to override a township or city's own ordinance⁵. The City of Marquette shows how specific local rules can get: RVs and other structures designed for occupancy of 14 days or less can't be used as dwelling units in city residential zones, with exceptions for Tourist Park, approved commercial RV establishments, and authorized emergency camping, but that rule applies only inside city limits, not countywide¹⁷. Some subdivisions also carry restrictive covenants on building size or placement, but the county is clear that no government agency enforces those privately created rules⁵.

How do septic and well permits work in Marquette County?

The Marquette County Health Department has jurisdiction countywide, in every incorporated and unincorporated area, for administering and enforcing onsite sewage treatment and disposal rules under the Upper Peninsula Environmental Health Code, effective since January 1, 2022⁶. Every permitted onsite system needs a final construction inspection before it's placed into use and before the Department signs off, and it's unlawful to backfill or cover a newly installed component until that inspection happens or the Department authorizes it; the installation contractor must give 72 hours' notice to schedule the inspection¹⁸. Soils are a serious constraint here: only 4.4% of Marquette County's soils are free of severe limitations for a conventional drain field, so plan for a site evaluation and likely an engineered system on most parcels¹³. A private well needs its own construction permit from the Department too, valid for 24 months with one possible 24-month extension; minor repairs like replacing a pump, screen, or pressure tank don't need a new permit, but new construction or an extensive change to an existing supply does¹². If public water is available, the Department checks with the municipal supplier before issuing a well permit at all¹².

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

Outside the City of Marquette, no official countywide rule reviewed for this guide directly addresses long-term RV occupancy on private land, so the answer depends on whichever township or city zoning ordinance covers your specific parcel². Inside the City of Marquette itself, the rule is explicit: RVs and other structures built for occupancy of 14 days or less can't be used as dwelling units in residential zones, aside from Tourist Park, approved commercial RV sites, or authorized emergency camping¹⁷. Tiny houses face a similar local-approval pattern statewide: Michigan treats a tiny house, even one built on wheels, as a building requiring local zoning, building, electrical, and plumbing approval plus local health-department permitting for any well or septic system, not as an automatically exempt recreational unit¹⁹. Because Marquette County itself sets no zoning rules, always confirm directly with your specific township or city before assuming either an RV or a tiny house is a legal full-time residence on your land.

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

First, get written zoning approval from your township or city, since the county's building permit can't be issued without it⁵. Second, if your home needs a septic system or well, contact the Marquette County Health Department's Division of Environmental Health for a site evaluation and permit before finalizing your plans²⁰⁶. Third, check whether your project needs a soil erosion permit; it's required if disturbed land falls within 500 feet of a lake or stream, or if you'll disturb more than one acre⁴. Fourth, submit your building permit application to Marquette County Building Codes along with your legal description and, if you're not doing the work yourself, your contractor's license information; a permit fee must be paid before issuance¹⁵⁴. Fifth, check whether other agency permits apply to your project, such as a driveway permit from the Marquette County Road Commission, a wetlands permit from the state, or airport-zoning review depending on where your property sits⁴. Sixth, don't start construction until the building permit is actually issued, since starting early adds a $300 administrative fee on top of the normal permit cost¹⁴. Seventh, schedule your septic final inspection with at least 72 hours' notice before backfilling any newly installed system component¹⁸.

What to check before you buy land in Marquette County

Septic is the biggest constraint on buildable land here: only 4.4% of Marquette County's soils are free of severe limitations for a conventional drain field, so get a Health Department site evaluation before you commit to a specific parcel¹³. The terrain is generally favorable despite the soil challenge, with 77.2% of the county at 15% slope or less, though 86.9% is wooded, so clearing costs are a real line item²¹²². Because zoning is entirely local, confirm with the specific township or city covering your parcel what its lot size, setback, and use rules actually require before assuming anything based on a neighboring parcel². If the land was recently subdivided, confirm the preliminary plat was properly reviewed, since Marquette County's Drain Commissioner reviews subdivisions within established drainage districts and preliminary plat approval lapses after two years if the final plat isn't submitted²³. Typical annual precipitation is 32.6 inches with severe drought in only about 1.7% of years, a relatively low water-scarcity risk for the Upper Peninsula²⁴²⁵. Budget for carrying costs too: Marquette County's effective property tax rate runs about 1.0%, with a median annual bill near $2,019 against a typical home value around $265,628²⁶²⁷²⁸.

Watch-outs

• Marquette County itself has no zoning ordinance; every lot size, setback, RV, and tiny-home question depends on the specific township or city covering your parcel, and written zoning approval from that local government is required before the county will issue a building permit⁵.
• The 14-day RV occupancy limit and Tourist Park exception apply only inside the City of Marquette's zoning code, not countywide; don't assume that rule applies to rural or township land elsewhere in the county¹⁷.
• As of March 9, 2026, Marquette County no longer administers plumbing and mechanical permits; those now go through the State of Michigan rather than the county building department¹⁵.
