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

52Index Score / 100
#40 of 56 in Montana

Richland County, Montana has a building department that reviews plans, issues permits and inspects covered work outside Sidney, but the county's code-enforcement certification is partial rather than a simple permit rule for every rural structure.1 Certain agricultural structures may qualify for an exemption, while electrical, plumbing and mechanical work may fall under state administration.2

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

Richland County enforces part of Montana's building code outside Sidney, so a rural project should be screened by the county Building Department before work begins.1 Montana's state permit program does not replace a certified local program within that local program's jurisdiction, and the state exempts several project types in areas it administers.11 Richland County separately says certain agricultural structures do not require a permit, but eligibility must be confirmed with the county Building Inspector or the Montana Building Division.2 For covered county work, inspections occur at the footing and foundation, framing, drywall and final stages.3

Who issues building permits in Richland County, Montana?

The Richland County Building Department reviews plans, issues building permits and certificates of occupancy, and performs county building inspections.12 The office is at 1105 3rd ST NW in Sidney and can be reached at 406-433-1122.12 For a permit administered by the state instead, Montana requires construction plans and a Building Permit/Plan Review Application before review and approval.13 Separate electrical, plumbing or mechanical permits may also be required for a state-administered project.13 Sidney city-limit land-use questions belong with the City of Sidney rather than the county Planning Department.4

Does Richland County, Montana have zoning?

Zoning in Richland County varies by location rather than operating as one confirmed countywide rule.4 The county Planning Department supports Richland County, its unincorporated communities and the Town of Fairview, while land-use planning inside Sidney goes to the city.4 Richland County publishes regulations and a map for the citizen-initiated McGlynn Reservoir zoning district, but that district document does not establish zoning across the whole county.5 Ask Planning to identify the parcel's governing district before relying on assumptions about setbacks, minimum home size, lot coverage or building height; countywide answers to those questions could not be confirmed.7

How do septic permits work in Richland County, Montana?

Richland County requires a local septic permit before any system is installed, and the Health Department reviews every parcel that applies.6 A property owner, installer or consultant submits the application with a $200 fee, while a county sanitarian or Montana-registered professional engineer must perform the site evaluation.6 A sanitary restriction can stop permit issuance until further review removes it, and floodplain boundaries, surface water, groundwater depth and lot size can constrain the design.6 Only 6.9% of county soils are rated without severe limitations for a conventional drain field, so make the site evaluation an early feasibility step.14

Can you live in an RV or tiny home in Richland County, Montana?

Richland County's rules for long-term RV occupancy on private land could not be confirmed, so ask the Planning Department and Environmental Health about the parcel, wastewater arrangement and intended length of stay.7 A county rule specifically addressing tiny-home occupancy also could not be confirmed, and the answer may depend on location-specific zoning plus the building and sanitation systems proposed.9 A tiny home that uses an on-site wastewater system still needs the county septic review and permit before installation.6 Rules for Montana public-use campsites do not answer whether someone may occupy an RV on private land.15

What are the steps to build a home in Richland County, Montana?

  1. Ask Richland County Planning which land-use rules and special districts apply to the parcel; Sidney city-limit projects go to the city.4
  2. Ask the Building Department whether the proposed home and accessory structures fall within county or state permit administration.1
  3. Apply to Environmental Health for septic review before installing a system and resolve any sanitary restriction or site constraint.6
  4. Check the county floodplain page and local administrator before development in a designated flood-hazard area.16
  5. Arrange the required building inspections as covered work reaches each listed stage.3
  6. If access meets a state highway, obtain the required Montana approach permit or right-of-way agreement from the appropriate district office.17

What should you check before buying land in Richland County?

Confirm the parcel's zoning district, subdivision status and whether it lies inside Sidney before treating rural land as buildable.4 Order septic feasibility early because only 6.9% of soils are rated without severe limits for a conventional drain field, and county review can also identify groundwater, surface-water, lot-size or sanitary-restriction barriers.146 Ask Floodplain Management whether the parcel needs floodplain permitting, and bring the legal land description or survey information requested by the county.18 Confirm legal access with Public Works for a county road or with Montana transportation officials for a state highway.1917 The county's effective property-tax rate is about 0.7%, and its median annual property-tax bill is $1,935.2021

Watch-outs

  • Do not assume one zoning answer applies everywhere: Richland County documents a special McGlynn Reservoir district, and Sidney handles land-use planning inside city limits.54
  • A septic permit can be delayed by a sanitary restriction or constrained by floodplain boundaries, surface water, groundwater depth and lot size.6
  • Private-land RV living, tiny-home occupancy, minimum dwelling size and general setbacks could not be confirmed; ask Richland County Planning before buying or placing a structure.7
