Change of Occupancy Permit in Helena, Montana

Required whenever a building's or tenant space's use/occupancy classification changes within Helena city limits (e.g., converting a mercantile space to a restaurant or assembly use). This is distinct from Helena's standard construction Building Permit: the City's 2020 Book of Fees (Exhibit A, Community Development Fees) lists a separate 'Building permit fee for occupancy change' line item, described as 'Permit for change of occupancy,' billed on an hourly 'whichever is greater' basis rather than the Ordinance 3134 valuation table used for new construction. It does not appear as its own named category on the City's public Building Permit Types page — its existence and fee structure are documented only in the adopted Book of Fees, so treat the process details below as the best-available grounded reading of that fee schedule, and confirm current process specifics directly with the Building Division.

Tips

  • Unlike most Helena building permits, a change-of-occupancy review is NOT billed off the Ordinance 3134 valuation table — it's billed hourly (minimum $56.00/hour, 'whichever is greater') per the City's 2020 Book of Fees, so cost scales with review time rather than project valuation.
  • This permit type isn't listed by name on the City's public Building Permit Types page — it only surfaces in the adopted fee schedule. Call the Building Division (406-447-8438) early to confirm the current application process for a pure occupancy-classification change with no accompanying construction.
  • If your occupancy change also involves construction work (remodel, tenant fit-out), you likely need this review in addition to — not instead of — the applicable building/electrical/plumbing/mechanical permits for the construction itself.
