This is PermitBase’s published record for East Helena as of 2026-07-20. It has since been superseded — see the current record. A historical record reflects what PermitBase had verified at that time; it may not capture a real-world change the jurisdiction had made but PermitBase had not yet verified, and it includes any errors we later corrected.

Codes adopted

Montana has a mandatory statewide building code administered by the Montana Department of Labor & Industry (DLI) Building Codes Bureau, amended by the Administrative Rules of Montana (ARM) Title 24, Chapter 301. Cities, counties, and towns may become 'certified' to locally administer permitting and inspection for all or part of the code (building, plumbing, electrical, mechanical, swimming pool, WUI, etc.); non-certified trades within a certified jurisdiction, and all trades in non-certified areas, fall under direct state administration by the DLI Building Codes Bureau. Source: Montana DLI Building Codes Bureau, Certified City, County and Town Programs and Current Codes pages (bsd.dli.mt.gov/building-codes-permits).East Helena is a Montana DLI-certified jurisdiction for Building (B) and Swimming Pool (SP) ONLY within East Helena city limits — Colin Thomas is the certified building official of record, (406) 594-6322. East Helena is NOT certified for Electrical (E), Plumbing (P), or Mechanical (M); those permits are issued directly by the state DLI Building Codes Bureau for all addresses within East Helena city limits.

Construction Permit — Deck / Accessory Structure (Garage, Shed)

Verified

Required for construction of decks, private garages, and accessory storage structures within East Helena city limits, issued under the city's Building (B) program. Structures for the owner's own use consisting only of minor work (see Informational Building Permit) may qualify for the lower-fee track; new construction of a deck, garage, or accessory building otherwise uses the standard Construction Permit Application and Plan Submittal Requirements.

Requirements

  • Zoning Application must be approved before the Building Permit Application is submitted
  • Construction Permit Application (Building & Safety) required, with project valuation, owner/contractor information, and description of project
  • Exterior deck framing connection detailing to supports, and railing post connections, must be shown per the city's Plan Submittal Requirements where a deck is part of new construction or an addition

  • A private garage or storage structure used only for the owner's own use may qualify for the Informational Building Permit ($25.00) only for the specific minor-work categories under City Code 4-1-13 — new construction of a garage/accessory structure itself requires the standard Construction Permit

Demolition Permit

Verified

Required for demolition of any structure within East Helena city limits. East Helena does not publish a dedicated demolition-specific application separate from its general Construction Permit Application; demolition is covered under the city's Building (B) certification and the standard Construction Permit process, per the Building & Safety Department's general permit notices.

Verified 2026-07-03 · Source

Requirements

  • Construction Permit Application must be submitted to City Hall for demolition of any structure within city limits, per the City of East Helena Department of Building & Safety's general permit process
  • Owner or applicant information, description of project (demolition scope), and estimated valuation required on the same Construction Permit Application form used for other building work
  • No dedicated demolition-specific bond, checklist, or fee line was found published separately by the City of East Helena — unlike Billings' explicit $10,000 demolition bond ordinance, no equivalent East Helena-specific bond requirement was located after checking the Planning/Zoning/Building page and the Construction Permit Application PDF
  • Coordinate with the East Helena Lead Education and Abatement Program (LEAP), Room 201 City Hall, (406) 457-8583, given the city's location within the East Helena Superfund Site Institutional Control Program (ICP) administrative area — demolition of older structures may raise ICP/lead-abatement compliance questions

Swimming Pool Permit

Verified

Required for construction/installation of a swimming pool within East Helena city limits. East Helena is one of the few Montana jurisdictions DLI-certified for Swimming Pool (SP) permitting in addition to Building (B), so this permit is issued locally by the Department of Building & Safety under the 2021 International Swimming Pool and Spa Code (ISPSC), rather than being routed to the state. No dedicated pool-specific application form or fee line distinct from the general Construction Permit Application was found published by the city.

Electrical Permit (State-Issued)

Verified

Required for electrical installation, alteration, or repair work anywhere in East Helena (city limits) and unincorporated Lewis and Clark County. Because East Helena is NOT electrically-certified, this permit is issued directly by the Montana Department of Labor & Industry Building Codes Bureau (Helena), not the city, under the 2020 NEC. The City of East Helena's own website links its 'Electrical Permits' page directly to the state DLI electrical-permits page, confirming this routing.

  • Payment must be submitted with the application; incomplete applications are returned unprocessed
  • Property address, GEOCODE/parcel/lot/block, owner information, and power company must be provided

Residential Solar Photovoltaic (PV) Permit — State-Issued Electrical Permit Add-On

Verified

Rooftop or ground-mount residential solar photovoltaic installation within East Helena city limits is not a separate stand-alone permit type — it is billed and processed as an Alternative Energy Source add-on to the state-issued Residential Electrical Permit, since East Helena is not DLI-certified for Electrical and all electrical permitting for East Helena addresses is issued directly by the Montana Department of Labor & Industry Building Codes Bureau (Helena) under the 2020 NEC. The Bureau's own Application for Residential Electrical Permit form itemizes 'Alternative Energy Source (solar/wind/hydro)' as a fixed $65 fee added on top of whichever base electrical work-type fee applies (e.g., service upgrade, change of service), and requires the applicant to specify the system type (Micro Inverter/AC Module System or PV String System).

EV Charger / EVSE Permit — State-Issued Electrical Permit (No Distinct Line Item)

Verified

Installation of a Level 2 (or higher) electric vehicle charger/EVSE anywhere in East Helena (city limits) requires an electrical permit, since East Helena is not DLI-certified for Electrical and all electrical permitting for East Helena addresses is issued directly by the Montana Department of Labor & Industry Building Codes Bureau (Helena) under the 2020 NEC. The Bureau's own Application for Residential Electrical Permit form (Rev. 12/22) has NO dedicated 'EV charger' or 'EVSE' line item — its explicit 'Alternative Energy Source' add-on fee is defined only for Solar/Wind/Hydro generation systems, not vehicle-charging equipment. An EV charger circuit is billed under the same general per-circuit/per-service fee table used for any other electrical equipment addition: as an added circuit to an existing panel (options G/H) if no service or panel change is needed, or under the applicable service-upgrade tier (options A-D) if the charger install requires a panel/service upgrade.

Verified 2026-07-20 · Source

Requirements

  • Apply using the same statewide Application for Residential Electrical Permit used for all East Helena electrical work, since the state DLI Building Codes Bureau (not the city) issues electrical permits for East Helena addresses
  • Select the base work-type fee matching the actual scope: '1 additional circuit or piece of equipment' (option H) or '2-3 additional circuits or pieces of equipment' (option G) for a charger added to an existing panel with no service change; or the applicable amp-rated service-upgrade tier (options A-D) if a panel/service upgrade is required to support the charger
