Zoning, building permits and septic rules in Poplar, Montana

Rules another office applies inside Poplar

Poplar does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

• Building permitLimited

  State-regulated construction inside Poplar city limits.

  • State permits are required for state-owned agencies and non-exempt buildings being built, remodeled, moved, or changing occupancy, except projects in a local-government program.
  • At the state level, farm or ranch buildings, private homes and apartments with four or fewer units that do not serve transient guests, specified industrial and mine buildings, and private storage buildings and garages are exempt.
  • Additional work may be exempt and the Bureau advises checking for local requirements.

  “A state building permit is required for any state owned agency or non-exempt building being built, remodeled, moved, or undergoing a change of occupancy, except for projects located within the jurisdictional limits of a local government program.”

• Building code adoptedAdopted (with conditions)

  Residential and commercial buildings inside Poplar city limits under the statewide Montana Building Codes Program.

  • A certified local government may enforce an approved local program; the state certified-jurisdictions page states that all other areas are under the State Building Codes Bureau.

  “In addition, the program is responsible for adopting a uniform state building code, which is enforced statewide for residential and commercial buildings across Montana.”

• InspectionsLimited

  Projects inside Poplar city limits that require a state Building Codes Program permit or inspection.

  • The cited statewide program statement limits the described inspection coverage to projects requiring a permit.

  “Field inspection staff for the programs are positioned around the state to ensure adequate coverage for inspection and regulation of projects requiring a permit.”

• Permit processPartial

  State Building Codes Bureau permit applications for projects inside Poplar city limits.

  • This describes only the state Bureau process, not a separately documented municipal permitting process.
  • The application warns that local zoning ordinances and flood-zone requirements may also apply.
  • The Bureau application requires a project number before fees are sent.

  “The building permit is applied for by completing and submitting the application for a building permit to the bureau.”
