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

Yes. The Iron County Construction Code office issues building permits for construction throughout the county's cities and townships.1 Michigan's current building code governs construction, while residential requirements are contained in the Michigan Residential Code.9 The county inspection schedule calls for seven inspections covering footings, drain tile, basement and garage floors, the roof after ice shield, rough-in work, insulation and the final inspection.10 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.11 Permit fees are published, but the inspector determines the fee after reviewing the submitted materials.12

Who issues building permits in Iron County, Michigan?

Iron County Construction Code is the building-permit office for Iron County.1 The office reviews the plans and must approve them before a permit is issued.8 Contact the office at its Crystal Falls address for the building application, current fee calculation and inspection scheduling.13 Mechanical and plumbing approvals may involve separate applications because the county's building application directs those trades to the appropriate division.8 The county process also requires local zoning approval, septic and well paperwork when applicable, plans, a completed application and contractor information when someone other than the owner will perform the work.8 No complete owner-builder exemption from permits or contractor-licensing rules was confirmed, so an owner planning to self-build should describe the work to the Construction Code office before contracting or starting.713

Does Iron County, Michigan have zoning?

Iron County's permit process sends applicants to the zoning official for the township or city where the parcel lies, and zoning approval must be attached before the county issues a building permit.2 Michigan law allows counties, townships, cities and villages to establish zoning districts, so the applicable local ordinance controls parcel-level land-use questions.5 Iron County's official material does not conclusively resolve whether a separate countywide zoning ordinance exists; start with the Construction Code office to identify the correct local zoning official.213 Ask that official about setbacks, minimum dwelling and lot size, building height, lot coverage, accessory dwellings, manufactured homes and agricultural structures before ordering plans.5 A county building permit is not a substitute for that local approval.12

How do septic and well permits work in Iron County?

The Dickinson-Iron District Health Department administers onsite sewage review and permitting in Iron County.14 For new construction, a site evaluation must determine whether the land is suitable for an onsite sewage permit before construction-code permits are issued.3 Permits or evaluations also apply to replacement systems, failed tanks, new or increased sewage flow, connecting a new dwelling to an existing system and a new vault or earth-pit privy.3 Only 0.8% of mapped soils avoid a severe limitation rating for a conventional septic drain field, so make health-department approval a purchase contingency rather than assuming a standard system will fit.15 The district also requires permits for new and replacement private residential wells and conducts final inspections of newly constructed wells.4 Contact the Crystal Falls health department office for the current applications.16

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 township or city zoning official serving the parcel whether an RV may be occupied, for how long and whether it may be used during construction.2 A tiny home does not bypass local review: Michigan guidance calls for applicable local zoning, building, electrical and plumbing permits and final approvals.6 Sanitary sewage from toilets, sinks, showers, washing machines and dishwashers must go to a municipal sanitary sewer or an onsite septic system.17 Minimum home size and the treatment of a tiny house on wheels were not confirmed countywide, so include both questions when speaking with the local zoning official.5

What are the steps to build a home in Iron County?

Use Iron County's document order so the building application is complete when submitted.8

  1. Identify the township or city zoning official and obtain the zoning or land-use approval for the jobsite.8
  2. Gather the parcel number, site address and a map with directions.8
  3. If the project is within 500 feet of running or standing water, obtain the applicable soil-erosion permit or exemption.8
  4. Obtain septic and well permits from the Dickinson-Iron District Health Department when applicable.8
  5. Assemble the address information, building plans, applicable engineered truss or slab documents, completed application and contractor information.8
  6. Submit the package and fee payment to Iron County Construction Code for plan review, then schedule the required inspections.810
  7. Request the certificate of occupancy after the permitted work is complete and the permits are final.11

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 parcel's proposed use and dimensional standards with the applicable township or city zoning official because Michigan zoning districts and their rules are locally adopted.5 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.1415 Confirm whether a private well is feasible and budget for the required permit if a new or replacement residential well is needed.4 Driveway-access and floodplain-development requirements were not confirmed, so ask Iron County Construction Code which road and floodplain authorities serve the parcel.13 For carrying costs, the countywide effective property-tax rate is 1.4%, but the actual parcel bill depends on its assessment and taxing districts.18

Watch-outs

  • Do not submit the building application before obtaining the applicable township or city zoning approval.2
  • A new onsite-sewage project needs a site evaluation before construction-code permits, and mapped soils rarely avoid severe conventional-drain-field limitations.315
  • Projects within 500 feet of running or standing water require soil-erosion documentation in the county permit package.8
  • RV occupancy, temporary camping, minimum dwelling size, setbacks and driveway rules remain unconfirmed; ask the local zoning official and Iron County Construction Code before relying on a parcel for those uses.213
