Do you need a building permit in Iron County, Michigan?
Yes. Iron County Construction Code requires a building permit for covered construction, with a complete paper document package left at the office before a permit can be issued.1 The current Michigan Building Code is the 2021 edition, while residential requirements are in the Michigan Residential Code.11 The county schedule lists inspections for footings, drain tile, basement and garage floors, the roof after ice shield, rough-in work, insulation and the final inspection.12 A new or altered building subject to Michigan's construction code may not be used or occupied until the code official issues a certificate of occupancy.13 Iron County publishes residential and commercial fee schedules, and the inspector determines the building-permit fee after reviewing the submitted materials; ask the building office for the current total.14
Who issues building permits in Iron County, Michigan?
Iron County Construction Code is the building-permit office for Iron County.1 The building inspector reviews and approves plans before issuing the permit.15 Contact the office at its Crystal Falls address for the application, current fee calculation and inspection scheduling.16 The permit package includes local zoning approval, parcel and site information, septic and well paperwork, plans, a signed application and contractor information when the owner will not personally perform the work.17 An owner may perform the work personally, but that is not an exemption from the building permit, plan review, local zoning approval or other required documents; work not performed by the owner must use a Michigan-licensed contractor.18
Does Iron County, Michigan have zoning?
Zoning approval in Iron County varies by city or township, and the county does not administer each local ordinance.2 Before the county issues a building permit, the applicant must contact the applicable local zoning official and attach that official's approval to the application.5 Michigan law allows counties, townships, cities and villages to establish zoning districts, so the ordinance for the parcel's jurisdiction controls land-use questions.8 Ask the local official about setbacks, minimum dwelling and lot size, building height, lot coverage, accessory dwellings, manufactured homes, RV use and agricultural structures before ordering plans.5 Iron County's materials do not answer those dimensional questions for every parcel; the Construction Code office can help identify the applicable local official.216
How do septic and well permits work in Iron County?
The Dickinson-Iron District Health Department serves Iron County, evaluates onsite sewage sites and administers the permitting program, while the Upper Peninsula Environmental Health Code supplies minimum site standards.3 For new construction, a site evaluation must determine whether the land is suitable for an onsite sewage permit before construction-code permits are issued.4 Permits or evaluations also apply to replacement systems, failed tanks, increased sewage flow, connecting a new dwelling to an existing system and a new vault or earth-pit privy.6 Only 0.8% of mapped soils avoid a severe limitation rating for a conventional drain field, so make health-department approval a purchase contingency rather than assuming a standard system will fit.19 The district requires permits for new and replacement private residential wells, inspects every newly constructed well and collects the required bacteria sample during the final inspection at no extra charge.20721 Contact the Crystal Falls office for current applications.22
Can you live in an RV or tiny home in Iron County?
A countywide rule allowing long-term RV occupancy or temporary camping on private land could not be confirmed for Iron County. Ask the city or township zoning official serving the parcel whether an RV may be occupied, for how long and whether it may be used during construction.5 A tiny home does not bypass local review: Michigan's rule for tiny houses used as resort cabins requires local zoning, building, electrical and plumbing permits and final approvals, and a unit on wheels cannot be treated as a recreational unit in that setting.9 That resort rule does not settle ordinary residential tiny-home occupancy on a private parcel, so ask the local zoning official about the proposed use and minimum dwelling size.2 Where public sewer is unavailable, a home must use an onsite sewage system, and even a new vault or earth-pit privy requires a permit.23
What are the steps to build a home in Iron County?
Use Iron County's required document order so the building application is complete when submitted.17
Identify the city or township zoning official and obtain zoning or land-use approval.5
Gather the parcel number, site address and a drawn map with directions.17
If the site is within 500 feet of running or standing water, obtain the required soil-erosion permit or exemption letter.17
Obtain applicable septic and well permits from the Dickinson-Iron District Health Department.15
Assemble the address information, plans, applicable truss or slab documents, signed application and contractor information.17
Leave the paper package and fee payment with Iron County Construction Code for plan review, then schedule inspections.1524
Request the certificate of occupancy after the permitted work is complete and the permits are final.13
What should you check before buying land in Iron County?
Make an accepted offer contingent on written zoning, septic, water and legal-access answers. Confirm the proposed use and dimensional standards with the parcel's city or township zoning official because local zoning varies across Iron County.2 Have the health department evaluate an unsewered homesite before closing; only 0.8% of mapped soils avoid a severe limitation rating for a conventional drain field.319 Confirm whether a private well is feasible and budget for its permit and final inspection.2521 Access from a Michigan state trunkline requires an MDOT driveway permit in addition to the local building permit.26 New residential construction is prohibited in a regulated floodway, while work elsewhere in a regulated river, stream or drain floodplain may require an EGLE permit and must meet elevation and fill rules.27 For carrying costs, the countywide effective property-tax rate is 1.4%, but the parcel bill depends on its assessment and taxing districts.28
Watch-outs
Do not submit the building application before obtaining the applicable city or township zoning approval.5
A new onsite-sewage project needs a site evaluation before construction-code permits, and mapped soils rarely avoid severe conventional-drain-field limitations.619
Projects within 500 feet of running or standing water require soil-erosion documentation in the county permit package.1
RV occupancy, temporary camping, minimum dwelling size, setbacks and driveway rules for roads other than state trunklines remain unconfirmed; ask the local zoning official and Iron County Construction Code before relying on a parcel for those uses.51626

Building in a floodplainRequired
Alteration or occupation of the 100-year floodplain of a Michigan river, stream, or drain regulated under Part 31.
The Part 31 permit requirement applies to rivers, streams, or drains with a drainage area of 2 square miles or greater.
A Part 31 EGLE permit is not required for alterations within floodplains of the Great Lakes, inland lakes, or watercourses with drainage areas less than 2 square miles, although other NREPA reviews may still be necessary.
Construction and fill may be permitted in non-floodway portions if local ordinances and building standards are met and compensating excavation is provided equal to the volume of fill placed in the floodplain.
New residential construction is specifically prohibited in the floodway.
The minimum residential elevation standard is one foot above the 100-year flood elevation, and some communities or counties may impose a higher standard.
Minimum drainage area for Part 31 floodplain authority: >= 2 square miles (Part 31 does not apply below this threshold) · Lowest-floor elevation: >= 1 foot above 100-year flood elevation (Some communities and counties may require a higher elevation)
“The Floodplain Regulatory Authority deals with the floodplains of rivers, streams, or drains which have a drainage area that is 2 square miles or greater. A permit is not required from EGLE, under Part 31, for alterations within the floodplains of the Great Lakes, inland lakes, or watercourses which have a drainage area less than 2 square miles.”
Campground & park staysLimited
Tiny houses, including tiny houses built on wheels, proposed as resort cabins or similar occupancy in Michigan.
The source distinguishes tiny houses from recreational units and states they cannot be treated as recreational units even if built on wheels.
The tiny house must be built as a resort rather than a campground.
Local health department permitting for wells, septic tanks, and drainfields is required as applicable.
Local zoning, building, electrical, and plumbing permits and final approvals are required under local authorities.
The source does not establish statewide zoning permission or a statewide right to occupy a tiny house.
“Local zoning, building, electrical, plumbing permits and final approvals under local authorities.”

county building authorityGeneral
Michigan counties serving as building-code enforcing agencies for residential construction in unincorporated areas, subject to the Statewide Jurisdiction List and local/state jurisdiction assignments.
Before construction, a written building-permit application must be submitted to the appropriate enforcing agency.
A permit is also required when use or occupancy changes.
Ordinary repairs do not require a permit, but the stated structural, egress, plumbing, electrical, mechanical, and public-health/safety limitations apply.
The Michigan Building Code and Michigan Residential Code govern construction; county enforcement applies only where the Statewide Jurisdiction List designates county jurisdiction.
“If COUNTY is indicated, that unit of government receives code enforcement services from a county enforcing agency.”
