Building permits, zoning and septic rules in Iosco County, Michigan
82Index Score / 100 #15 of 83 in Michigan
Iosco County, Michigan requires a building permit for new commercial and residential construction within the Building Department’s jurisdiction, including pools, decks, carports, and sheds over 200 square feet1. Zoning approval comes from the township or city that contains the parcel, such as a zoning permit in Grant Township for a building of any size23. Septic permits for every address in Iosco County come from District Health Department No. 2, not the building department or the township4.

Do you need a building permit in Iosco County, Michigan?
Yes. The Iosco County Building Department requires a permit for new commercial and residential construction within its jurisdiction, including above-ground and in-ground swimming pools, decks, carports, and sheds over 200 square feet1. Roofing and siding permits are no longer required within the department's jurisdiction15. Michigan's construction codes apply statewide, and the appropriate enforcing agency may be the state, county, or local government; the Iosco County Building Division enforces the Michigan Building Code and Michigan Residential Code where it has jurisdiction166. Ordinary repairs generally do not need a permit, subject to exceptions for structural, egress, plumbing, electrical, mechanical, health, and safety work17. An owner may use Michigan's licensing exception when building for the owner's own use and occupancy, but that exception does not waive the building permit10. Submit the signed application with the proper fee and the required zoning, septic, soil-erosion, and flood-zone approvals18.
Who is the Iosco County building department, and how do you reach them?
The Iosco County Building Department issues building, plumbing, mechanical, and electrical permits and runs inspections for the county19. The county's building-department page was unreachable at the time of this guide, so confirm current phone and office hours through the county's main line before you visit19. Inspections follow a set sequence: a footing inspection before concrete is poured, a foundation or backfill inspection for crawlspaces and basements, rough-in and framing inspections once subtrades are installed but before insulation or interior finishes, and a final inspection only once the project is 100% complete, including a blower-door test and approved electrical, plumbing, and mechanical work20. A new or altered building can't legally be occupied until the code official issues a Certificate of Occupancy, which the permit holder requests in writing once every fee is paid and all permitted work is finaled21.
Does Iosco County have zoning, and who sets it?
The Iosco County Building Division enforces zoning ordinances within its jurisdiction, but we could not confirm a single countywide zoning ordinance that governs every parcel22. The county Planning Commission coordinates zoning and planning activities of the county’s townships and cities, and local requirements vary by township and city2. Grant Township, for example, requires a zoning permit for any type or size of building3. In Alabaster Township’s R-1 Rural Residential District, a single-family lot needs at least 20,000 square feet and 100 feet of width, with 40-foot front and rear setbacks2324. That is one township’s district rule, not a rule for the whole county. We could not confirm countywide rules for minimum dwelling size, lot coverage or building height. Ask the township or city that contains the parcel for its zoning map and ordinance, then ask the Iosco County Building Department which construction approvals it handles. A county building permit does not by itself establish that the proposed land use is allowed.
How do septic and well permits work in Iosco County?
District Health Department No. 2 administers onsite sewage disposal in Iosco County, and the county requires its septic approval before issuing a building permit4. Installing or repairing a residential system requires a DHD2 construction permit and a $325 fee; DHD2 then reviews the site and soils and issues a permit only if conditions allow9. Only 0.5% of county soils are free of severe limitations for a conventional drain field, so make the site evaluation an early purchase contingency25. DHD2 must inspect the completed system before it is covered or backfilled26. Off-grid does not mean sanitation-free: an alternative system must have local health-department approval, and a compost toilet may qualify only as an approved innovative or alternative treatment system13. If an available public sewer passes within 200 feet, connection depends on the applicable local government's requirement and generally must be completed within 18 months after the triggering event27. A new or replacement private well needs a separate DHD2 permit before construction11.
Can you live in an RV or tiny home on your land in Iosco County?
We could not confirm a general right to live in an RV or tiny home on ordinary private land in Iosco County; ask the parcel's township zoning office before relying on either use28. Michigan allows qualifying park models and camping cabins on licensed campsites in licensed campgrounds, but those campground rules do not authorize residential use on a private parcel2930. A tiny house, including one on wheels, still needs applicable local zoning, building, electrical, and plumbing approvals31. Sanitation is a separate constraint: sewage must go to an approved system, and alternative or composting systems require local health-department approval3213. Where a public sewer is available, the local government may require connection rather than an onsite option27. Confirm the proposed use with the township and the wastewater plan with DHD2 before buying or placing a unit4.
Building a home in Iosco County: the steps, in order
Identify whether the parcel is in a township, city, or village and obtain that jurisdiction's zoning answer7.
Ask DHD2 whether public sewer availability affects the parcel, then obtain the required septic site review and permit or sewer approval427.
Obtain a separate DHD2 permit before constructing a new or replacement well11.
Submit the signed building application and proper fee to the Iosco County Building Department with zoning, septic, soil-erosion, and flood-zone approvals1918.
Get Road Commission approval before work in the county road right-of-way, and secure any applicable state floodplain permit331234.
Schedule footing, foundation, rough-in, and final inspections, then request the Certificate of Occupancy after all work is finaled2021.
What to check before you buy land in Iosco County
Make septic feasibility a purchase contingency: only 0.5% of Iosco County soils are free of severe limitations for a conventional drain field25. Confirm the parcel's local zoning, public-sewer status, floodplain exposure, and driveway access before committing7273412. Michigan regulates subdivision plats under the Land Division Act, with state final review; lakefront, streamfront, channel, lagoon, and floodplain proposals can also require EGLE review35. Farm buyers should not treat Michigan's agricultural production sales and use tax exemption as a building or zoning exemption: eligibility depends on how qualifying property is used, mixed uses must be apportioned, and land-use rules still apply14.
Watch-outs
We could not confirm one zoning ordinance for all of Iosco County; ask the parcel's township, city, or village for its zoning district, setbacks, and dimensional standards7.
We could not confirm a general right to live in an RV or tiny home on ordinary rural land outside a licensed campground; ask the parcel's township about land use and DHD2 about sanitation2813.

Michigan residential-builder licensing when an individual erects a residential structure or combination residential and commercial structure for the individual's own use and occupancy on the individual's property.
The exemption concerns the residential-builder licensing definition and does not eliminate otherwise applicable building-permit, inspection, code, zoning, or utility requirements.
The owner-builder must personally satisfy the statutory own-use, own-occupancy, and own-property conditions stated in the source.
The source states that persons constructing residential structures for compensation are generally within the residential-builder licensing definition, subject to statutory exceptions.
