EV Charger / EVSE Permit in Hamilton, Montana

Hamilton has no dedicated EV charger or EVSE permit and no distinct fee line item for electric vehicle charging equipment on the City's Electrical Permit Application. EV charger circuit work is billed as a standard electrical installation under the same City of Hamilton Electrical Permit used for all wiring work -- typically the flat 'one additional circuit or piece of equipment' fee (the same category used for a hot tub or air conditioner circuit) for a single charger added to an existing single-family home, or the general valuation-based tiers for larger/commercial installations. Hamilton is a Montana DLI-certified jurisdiction, so permits are issued locally by the City Building Department, not the state.

Tips

  • Hamilton has no EV-specific permit or fee -- a single charger added to an existing home is priced the same as adding a hot tub or A/C circuit ($45 flat), per the City's Electrical Permit Application.
  • Larger or commercial charger installations (e.g., multi-space workplace or fleet charging) fall under the general valuation-based tiers, not a flat fee.
  • Hamilton is Montana DLI-certified for electrical permitting, so this permit is issued by the City Building Department directly, not the State.
