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

A single-family home in unincorporated Hill County does not require a state structural building permit; Montana also exempts farm and ranch buildings, residential buildings with fewer than five dwelling units unless they serve transient guests, and qualifying private garages and storage buildings1. The exemption is only from the state building permit: a farm or ranch building may still face zoning, subdivision, floodplain or septic rules10. Covered non-exempt work outside a certified local jurisdiction goes through the Montana Building Codes Program1. Projects that require a state permit are inspected by the state program, and the permit holder must arrange access when work is ready11. Hill County separately requires a $75 zoning permit for any work outside city limits within the City-County Planning area2.

Who handles building and zoning permits in Hill County?

Start with the Hill County Planning Office for land-use approval. The office administers county zoning, subdivision and floodplain regulations as well as overall land-use management1213. The Planning Office lists 406-740-7250 and [email protected]6. Its $75 zoning permit applies to any kind of work outside city limits within the City-County Planning area, although the county page does not publish a complete application, review or timing procedure14. For covered non-exempt construction in unincorporated Hill County, use the Montana Building Codes Program for the state permit and inspections115. State building-permit fees depend on the applicable valuation method, and a plan-review fee equal to 35 percent of the building permit fee must be paid before issuance16. Havre has a certified building jurisdiction within city limits, so take a city project to Havre rather than using the unincorporated-county path17.

Does Hill County have zoning?

Hill County has zoning, but the stated permit rule covers land outside city limits within the City-County Planning area rather than saying that every unincorporated parcel is covered2. Ask the Planning Office to confirm whether a tract lies inside that area before relying on the county process6. The available county material does not give district boundaries, setbacks, minimum lot size, minimum dwelling size or lot-coverage limits, so ask Planning for the parcel's district and dimensional standards56. Hill County also regulates subdivision activity and administers both its subdivision regulations and the Montana Subdivision and Platting Act18. That makes Planning the first call before dividing acreage as well as before building. Montana law authorizes a county with an adopted growth policy to zone all or part of its jurisdiction, and Hill County Planning administers the county growth policy and zoning regulations196.

How do septic permits work in Hill County?

Hill County Environmental Health administers individual sewage permitting4. A permit is required before installing a new septic system or modifying or updating an existing one20. The office can be reached at 406-400-2366 or [email protected], and its page asks callers to leave a voicemail for county staff21. A Montana Certificate of Subdivision Approval does not replace the local drainfield permit22. Site conditions deserve early attention because only 8.4% of Hill County soils are rated without severe limitations for a conventional septic drain field9. Hill County has not stated a septic inspection sequence or fee in the cited material, so ask Environmental Health about site evaluation, design, inspections and the current charge before choosing a house site2321.

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

We could not confirm a Hill County rule that gives a general yes-or-no answer for long-term RV occupancy or tiny-home occupancy on private rural land. Any work outside city limits within the City-County Planning area requires the county zoning permit, so ask the Planning Office how the parcel's district treats an RV residence, a tiny home on a foundation, a tiny home on wheels and an accessory dwelling26. Montana's camping rule for Fish, Wildlife & Parks sites is not a private-land rule because it applies only to those public-use sites24. A tiny home that needs a new septic system or changes an existing system must obtain the Hill County septic permit3. The available material also does not confirm a minimum dwelling size, so get that standard from Planning before selecting a structure56.

Building a home in Hill County: what are the steps?

  1. Ask the Hill County Planning Office whether the parcel is in the City-County Planning area and whether subdivision or floodplain review applies1213.
  1. Obtain the $75 zoning permit before work if the site is outside city limits within that planning area2.
  1. Confirm whether the project is exempt from a state structural permit; a single-family home is exempt, while covered non-exempt work goes to the Montana Building Codes Program1.
  1. For a covered project, submit the state application and plans, pay the permit and plan-review fees, and arrange required inspections as work becomes ready251611.
  1. Evaluate the septic area early because only 8.4% of county soils lack severe limitations for a conventional drain field9.
  1. Obtain the Hill County septic permit before installing or changing the system3.

What should you check before buying land in Hill County?

Verify zoning, water, wastewater, flood exposure, subdivision status and legal access before closing. Hill County averages about 12.8 inches of precipitation a year, and severe drought occurs in 14.8% of years, so a dependable water plan matters2627. New or expanded groundwater use generally requires a Montana water-use permit, though a small groundwater development may qualify for an exception; beginning January 1, 2026, the state requires a Notice of Intent before using water under a permit exception8. Only 8.4% of county soils lack severe limitations for a conventional septic drain field, so make septic feasibility part of the purchase contingency9. Hill County administers floodplain regulations, but the cited county material does not state the local thresholds or process; ask Planning whether the parcel needs floodplain review136. A new or modified approach onto a state highway requires an approach permit or right-of-way agreement from the appropriate Montana Department of Transportation district office28.

Watch-outs

  • A state residential building-permit exemption does not cancel Hill County's $75 zoning permit inside the City-County Planning area12.
  • Hill County has not published a confirmed private-land rule for long-term RV or tiny-home occupancy on the cited pages; ask the Planning Office about the parcel and proposed use56.
  • Most Hill County soils carry severe limitations for a conventional septic drain field, so establish septic feasibility before choosing the house site9.
  • No explicit owner-builder exemption could be confirmed for Hill County, so ask the permitting office responsible for each approval before assuming self-performed work is exempt7.
