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

Yes. Keweenaw County requires permits before regulated construction begins, although listed repair and minor-work exceptions apply1. An accessory structure of 200 square feet or less does not need a building permit but still needs a zoning permit1. Building permits are also not required for painting, private sidewalks and driveways, patios, and retaining walls of 18 inches or less13. The county administers the Michigan Building Code and related state construction codes according to the project14. County zoning approval must come before the building-permit application1. Permitted work is subject to inspections, and county inspection requests require at least 72 hours' notice1516. Keweenaw County offers no owner-builder exemption from its permit requirements, although Michigan has a narrow builder-licensing exemption for a person building a residence for personal use and occupancy on that person's own property1112.

Who is the Keweenaw County building department?

The Keweenaw County Zoning and Construction Codes Department is the starting point for county zoning and construction permits17. Its permit clerk handles building, electrical, mechanical, plumbing and soil-erosion intake at 5095 4th Street, Eagle River, MI 49950, phone 906 523-857017. Applications may be emailed or hand-delivered with the site plan, required information and permit fee18. Building applications require floor plans and specifications, and the county says to allow 5 business days when documentation is complete18. Most buildings need a certificate of occupancy before use, but single-family homes, individual apartment units and individual office suites are exceptions; issuance follows completed construction and final inspection reports19.

Does Keweenaw County have zoning?

Keweenaw County administers zoning in Grant, Sherman, Houghton and Allouez townships and Ahmeek Village2. Eagle Harbor Township has separate zoning, so buyers there should use the township's rules rather than county tables3. In county-administered areas, permitted uses, setbacks and lot coverage depend on the zoning district202122. The Agricultural Zoning District has a 5-acre minimum lot size23. Lakefront and riverfront structures generally have a 75-foot high-water-mark setback, except in RS-1, while other setbacks vary by district21. A variance can reduce a waterbody setback to no less than 50 feet where unique conditions make 75 feet economically infeasible24. Single-family lots in the CE and RR districts are limited to 30% coverage, and the schedule lists 35 feet and 2.5 stories as the height limit for several residential uses, with a 28-foot maximum on waterfront lots2526. Single-family dwellings include mobile and manufactured homes, which are permitted by district, while a mobile-home park of three or more homes needs a conditional-use permit in R-227. Short-term rentals are conditional uses in the listed residential, resource, conservation and agricultural districts28. The county zoning-permit application fee is $5029.

How do septic and well permits work in Keweenaw County?

Western Upper Peninsula Health Department handles onsite wastewater permits and inspections in Keweenaw County56. Its Houghton and Keweenaw office is at 540 Depot St, Hancock, MI 49930, phone (906) 482-738230. A new or replacement septic system needs a suitable site evaluation, an approved application and paid fees before construction31. The installer must request final inspection, and the system cannot be covered until it receives final approval and an approved tag6. Private well construction likewise requires an approved application and fees before work starts32. Do the site work early: 0% of mapped county soils are rated free of severe limitations for a conventional drain field33. New construction needs an existing or permitted well and septic system before county zoning approval4.

Can you live in an RV or tiny home in Keweenaw County?

Keweenaw County treats temporary dwellings, tents, yurts and recreational vehicles outside campgrounds as a regulated zoning use8. The county ordinance generally limits an RV stay to 90 days unless a principal-structure building permit or a qualifying special use applies; residential districts are limited to one RV, and potable-water, sewage and setback rules also apply8. A tiny home under the county ordinance must have a foundation, potable water and a health-department-approved sewage system, along with the district's dimensional rules and applicable permits and codes9. An ECHO accessory dwelling is allowed in listed districts, with no more than one per lot; a detached unit must meet principal-building setbacks and lot coverage and sit at least 10 feet from the existing dwelling34. Eagle Harbor Township has separate zoning, so confirm these uses with the township for parcels there35.

What are the steps to build a home in Keweenaw County, Michigan?

  1. Identify the zoning authority; county zoning covers Grant, Sherman, Houghton and Allouez townships and Ahmeek Village, while Eagle Harbor Township has separate rules23.
  2. Confirm the district, use, setbacks and lot coverage before designing202122.
  3. Obtain well and septic approvals or document existing systems before seeking county zoning approval4.
  4. Submit the site plan and supporting material with the $50 county zoning fee1829.
  5. After zoning approval, submit floor plans and specifications for the building permit18.
  6. Schedule required inspections with at least 72 hours' notice15.
  7. Obtain a certificate of occupancy when required; single-family homes are exempt from that county certificate requirement19.

What should you check before buying land in Keweenaw County?

Start with septic feasibility because 0% of mapped county soils are rated free of severe limitations for a conventional drain field33. Confirm the governing zoning authority and district before relying on a proposed use, especially in Eagle Harbor Township3536. A proposed lot division must comply with Michigan's Land Division Act and county rules, and the resulting lots must still meet district, well and septic requirements37. Development in a county-designated special flood-hazard area is generally prohibited except for listed compliant uses, and occupied levels must be at least 1 foot above base flood elevation38. Ask the Keweenaw County Road Commission about access because it processes right-of-way permits through Oxcart39. The effective property-tax rate is about 0.9%, with a median annual bill near $1,7044041.

Watch-outs

  • Eagle Harbor Township has separate zoning regulations, so county zoning tables should not be applied to a parcel there35.
  • County zoning approval for new construction requires an existing well and septic system or valid permits for both427.
  • Private-land RV stays are regulated and generally face a 90-day limit unless a principal-structure building permit or qualifying special use applies8.
  • Keweenaw County has no owner-builder exemption from permits, even when the owner performs the work11.
