Building permits, zoning and land rules in Mineral County, Montana

75Index Score / 100
#4 of 56 in Montana

Unincorporated Mineral County, Montana does not require a county building permit for a home, and Montana's statewide exemption for single-family homes outside a certified local program means most residential construction doesn't need a state permit either12. The county runs its own septic program through Environmental Health and Planning rather than leaving it entirely to the state3. Mineral County has no countywide zoning; only the incorporated Town of Alberton has adopted its own zoning ordinance4.

Do you need a building permit in Mineral County, Montana?

A single-family home in unincorporated Mineral County does not need a building permit1. Mineral County is not a certified local building-code jurisdiction, so it falls under state authority, where Montana law exempts residential buildings with fewer than five dwelling units, farm and ranch buildings, and private garages and storage buildings used for the owner's own use2. The residential exemption does not cover a building serving transient guests, so a cabin or house intended for short-term rental can require a state building permit and a state Property Manager license unless an exemption applies211.

Who handles building permits, septic and floodplain in Mineral County?

Mineral County does not operate a local building-permit program1. Septic and wastewater treatment systems, subdivision review and floodplain permits are handled by Mineral County Environmental Health and Planning at (406) 822-3525612. County-road driveway and approach permits go through the Mineral County Road Department at (406) 822-356013. For a nonexempt project, such as a commercial building or a residential building serving transient guests, building permits and inspections come from the Montana Building Codes Program in Helena at (406) 841-20561415.

Does Mineral County have zoning?

Mineral County has no countywide zoning5. The county's Community Wildfire Protection Plan says Alberton is the county's only incorporated community with adopted zoning4. Alberton's zoning ordinance establishes Residential 1, General Commercial and Public/Open Space districts inside town limits16. Mineral County still regulates subdivision of land countywide, including in Alberton and Superior, so dividing a parcel is a separate question that needs county review17. We could not confirm a countywide rule for a single RV, tiny home, accessory dwelling, manufactured home, minimum home size or residential setback; ask Environmental Health and Planning about the parcel before relying on the absence of countywide zoning6.

How do septic permits work in Mineral County?

Septic and wastewater treatment systems in Mineral County go through Environmental Health and Planning, which publishes the county regulations and permit request form63. The application must include the applicable fee before review, and construction without an issued installation permit or approved site evaluation carries a $500 fee18. The installer must notify the department at least 48 hours before completion, and the completed system needs a final inspection before it is covered19. Only 0.1 percent of Mineral County soils are rated without severe limitations for a conventional septic drain field, so make the site evaluation an early purchase contingency and budget for the possibility of an alternative design20. A state subdivision sanitation approval does not replace the local drainfield permit21.

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

Mineral County's subdivision regulations cover developments providing two or more recreational-camping-vehicle spaces and send those projects through RV-park review7. That rule addresses multi-space developments, not one household living in one RV on privately owned land7. We could not confirm a countywide private-land rule that allows or prohibits living in one RV, or a countywide siting rule for a tiny or manufactured home. Ask Mineral County Environmental Health and Planning about the parcel, wastewater plan and floodplain status before moving an RV or home onto the site612.

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

  1. Confirm whether the parcel is inside Alberton, where the town's zoning ordinance applies16.
  2. Confirm that the project qualifies for Montana's building-permit exemption; contact the Montana Building Codes Program before starting any nonexempt project214.
  3. Apply to Environmental Health and Planning for septic approval, and make the site evaluation an early step because only 0.1 percent of local soils are rated without severe limits for a conventional drain field620.
  4. For a new or expanded well, determine whether the use fits the 35-gallon-per-minute and 10-acre-foot annual limits for a permit exception, then file the required Notice of Intent before using the water10.
  5. Apply to the Road Department for an approach on a county road, or to the appropriate Montana Department of Transportation district office for an approach on a state highway89.
  6. Ask Environmental Health and Planning whether the site is in a designated flood hazard area and obtain any required floodplain permit before development1222.

What to check before you buy land in Mineral County

Mineral County is steep, forested and mostly public land: only 8.1 percent of the county is at a 15 percent slope or less, 91.8 percent is wooded, and 82 percent is federal land232425. Only 0.1 percent of county soils are rated without severe limitations for a conventional septic drain field, so make buildability and septic feasibility purchase contingencies20. Mineral County averages 38.2 inches of precipitation a year and has experienced severe drought in about 14.5 percent of years2627. The county has about 4.2 people per square mile and 5,090 residents, while the nearest city of 100,000 or more is about 118 miles from the county center282930. The effective property-tax rate is about 0.6 percent, and the median annual property-tax bill is about $1,7283132.

Watch-outs

  • The county plan says Alberton is the only incorporated community with adopted zoning, but we could not confirm whether Superior has since adopted zoning; ask the Town of Superior before relying on an unzoned status there4.
  • We could not confirm whether Mineral County allows living in one RV or tiny home on private land; the county rule addresses developments with 2 or more RV spaces, not a single household's use7.
  • We could not confirm countywide rules for owner-builders, certificates of occupancy, manufactured-home siting or accessory dwellings; ask Environmental Health and Planning before making a purchase or construction decision6.

  • Living in an RVLimited

    Developments in Mineral County providing two or more recreational-camping-vehicle spaces, including recreational-vehicle parks and subdivisions created by rent or lease; this claim describes county subdivision-review controls and is not a countywide ban on a single RV.
