EV Charger / Electric Vehicle Charging Station Permit in Lewistown, Montana
Montana has no dedicated EV-charger permit type or fee line, and Lewistown is DLI-certified for Building only (not Electrical), so installing a Level 2 (240V) home EV charger or EVSE within Lewistown city limits requires a State of Montana Electrical Permit issued directly by the DLI Building Codes Bureau (Helena) -- not the City of Lewistown -- billed under the same general residential wiring/circuit line items used for any new dedicated circuit or service upgrade. A separate City of Lewistown Building Permit is only needed if the installation also involves new structural work (e.g., a new carport or accessory structure).

When you need this permit
- Electrical work must be performed and the permit pulled by a Montana-licensed electrical contractor (LCO/UCO), per the Application for Residential Contractor Electrical Permit (Rev 6/24)
- If the EV charger is added as a new dedicated circuit to an existing panel with no service/panel change, this is billed under the form's 'Single Family Interior/Exterior Wire or Rewire' section, line H ('1 additional circuit or piece of equipment') or line G ('2-3 additional circuits or pieces of equipment') depending on scope
- If the installation requires a panel upgrade or new/upsized electrical service to support the charger's amperage draw, it is billed instead under the amperage-based 'Single Family Dwelling or Cabin' service tiers (A-D)
- The state application form has no Alternative-Energy-style checkbox or dedicated question set for EV chargers (unlike its Solar/Wind/Hydro section) -- EVSE is treated as ordinary residential branch-circuit wiring
- A City of Lewistown Building Permit is required in addition only if the EVSE is mounted on, or paired with, new structural construction (e.g., a new carport or accessory structure); not required for a simple wall/pedestal-mounted charger on an existing structure

Tips
- There is no dedicated 'EV charger' or 'EVSE' checkbox anywhere on Montana's state electrical permit form -- unlike solar, which gets its own Alternative Energy Source question set, an EV charger circuit is simply billed as ordinary new/additional wiring.
- Whether your job falls under the flat additional-circuit fee ($45-$70) or the amperage-based service tiers depends on whether your existing panel has enough spare capacity -- ask your electrical contractor to specify this on the application.
- Because Lewistown is not electrically-certified, do not attempt to pull this permit from the City -- it must go to the State DLI Building Codes Bureau in Helena, the same office that handles Lewistown's other electrical work.
- No separate City of Lewistown permit is needed for a straightforward wall-mounted or pedestal EV charger with no new structure; only pull a City Building Permit as well if you're also constructing a new carport or similar structure to house it.
