Applicants must contact the Building Department at (406) 665-9260 Ext. 106 for a current fee quote. |

VerifiedRequired for accessory structures (sheds, detached storage buildings, etc.) in Hardin. The City publishes a dedicated Application For Business Accessory Building for accessory structures on business/commercial property, governed by Hardin City Code 11-1-8-2, which caps accessory buildings at 200 square feet without a Variance Request. Residential accessory structures fall under the general residential-building-permit process.

Commercial Building Permit (State-Issued)
VerifiedBecause Hardin's DLI certification for Building covers RESIDENTIAL work only, any commercial building project within Hardin city limits — new construction, addition, alteration — requires a Building Permit/Plan Review Application issued directly by the Montana DLI Building Codes Bureau in Helena, not by the City of Hardin, under the 2021 IBC.
Verified 2026-07-03 · Source
Requirements
- Submit a Building Permit/Plan Review Application together with complete construction plans to the Building Codes Bureau
- Plan review fee is generally 1%-2% of building valuation, calculated by the Bureau after initial screening
- A state building permit must be obtained before construction begins; starting construction beforehand may result in an investigation fee and required corrective construction
- Building permits must be issued before related Plumbing, Mechanical, or Electrical permits can be issued or that work can begin
- Design professionals are encouraged for complex projects; complete plans expedite review
- Apply in accordance with Title 50, Chapter 60, MCA and ARM Title 24, Chapter 301

Electrical Permit (State-Issued)
VerifiedBecause Hardin holds no DLI certification in Electrical (only a residential-only Building certification), electrical work anywhere within Hardin city limits — residential or commercial — requires a Residential or Commercial Electrical Permit issued directly by the Montana DLI Building Codes Bureau in Helena, not by the City of Hardin, under the 2020 NEC.

Plumbing Permit (State-Issued, incl. Water Heater)
VerifiedBecause Hardin holds no DLI certification in Plumbing (only a residential-only Building certification), plumbing work anywhere within Hardin city limits — including water heater installation/replacement, residential or commercial — requires a Plumbing Permit issued directly by the Montana DLI Building Codes Bureau in Helena, not by the City of Hardin, under the 2021 Uniform Plumbing Code.

Mechanical / HVAC Permit (State-Issued)
VerifiedBecause Hardin holds no DLI certification in Mechanical (only a residential-only Building certification), mechanical/HVAC work anywhere within Hardin city limits — residential or commercial — requires a Mechanical Permit issued directly by the Montana DLI Building Codes Bureau in Helena, not by the City of Hardin, under the 2021 International Mechanical Code and International Fuel Gas Code.

Demolition / Building Removal Permit
VerifiedRequired for demolishing or removing a structure within Hardin city limits, using the City's residential-building-permit process (Type of Work checkboxes on the same Application For Building Permit include 'Moved Building' and 'Other', the latter used with a full description of work for demolition scope) for residential property; commercial demolition follows the state-routed process since Hardin's certification excludes commercial building work.
Verified 2026-07-03 · Source
Requirements
- Type of Work box 'Other' checked on the Application For Building Permit with a full description of the demolition scope attached, or 'Moved Building' for relocating a structure
- Project valuation (prior value and completed/post-project value) must be provided
- Property address, GEOCODE, parcel/lot/block information required as with any other permit type on this form
- For commercial structures, submit instead to the Montana DLI Building Codes Bureau since Hardin's certification does not cover commercial building work
Required documents
- RequiredApplication For Building Permit (Other/Moved Building)Same City of Hardin form used for all residential building/zoning work, with 'Other' or 'Moved Building' selected and a full work-scope description attached

|---|---|---|
| Demolition/building permit fee | No fixed table was found published on hardinmt.com, hardinmontana.info, or the City's Building Permit Application form; no dedicated demolition bond amount (comparable to Billings' $10,000 site bond) was found published for Hardin either. Contact the Building Department at (406) 665-9260 Ext. 106 for current requirements and fees, since this is a small jurisdiction without Billings-scale published demolition procedures. |
Solar Photovoltaic (PV) Permit
VerifiedRequired for installation of rooftop or ground-mount solar photovoltaic systems within Hardin city limits. For a RESIDENTIAL installation: a City Building Permit (structural/racking, issued by the City's Building Inspectors) plus a State of Montana Electrical Permit (wiring/interconnection) -- Hardin is city-certified for residential Building permits only. For a COMMERCIAL installation: BOTH the building permit and the electrical permit are issued directly by the Montana Department of Labor & Industry Building Codes Bureau, since Hardin's local certification does not extend to commercial building work or to any electrical/plumbing/mechanical permits of any project type.
Verified 2026-07-20 · Source
Requirements
- Residential solar: City Building Permit Application (structural/racking scope) submitted to City Building Inspectors Joe Connelly or Nathan McConnell
- Residential solar electrical scope: State of Montana Application for Residential Contractor Electrical Permit -- Hardin is not certified for electrical permitting of any project type
- Commercial solar: BOTH the building permit and electrical permit are issued directly by the Montana Building Codes Bureau, not the City, per Hardin's certification (residential building only)
- Licensed electrical contractors select 'Solar' as the Alternative Energy Source on the state electrical application and specify Micro Inverter/AC Module System or PV String System, and whether the system produces 90 or more volts
- Non-electrician installers submit the state's Alternate Energy Permit instead of the standard contractor electrical permit, per Montana Building Codes Bureau Alternative Energy Information guidance
Required documents
- RequiredCity of Hardin Application For Building PermitFor the residential structural/racking scope only; commercial building goes through the state instead
- RequiredMontana Application for Residential (or Commercial) Contractor Electrical PermitState of Montana Building Codes Bureau form; includes an Alternative Energy Source section (Solar/Wind/Hydro checkbox, system type, voltage)

| State Electrical Permit -- Alternative Energy (residential, by licensed contractor) | $45 | Montana Building Codes Bureau, Application for Residential Contractor Electrical Permit (Rev 6/24), line item K 'Alternative Energy' -- applies to Hardin since the City is not certified for electrical permitting of any project type |
| Commercial Building Permit/Plan Review Fee (state-issued, applies to commercial solar) | Generally 1%-2% of building valuation, calculated by the Building Codes Bureau after screening | Montana DLI Building Codes Bureau, 'Is a State Building Permit Needed?' guidance page -- consistent with this corpus's existing commercial-building-permit-state entry for Hardin, since Hardin's certification does not cover commercial building work |

EV Charger / EVSE Permit
VerifiedBecause Hardin holds no DLI certification in Electrical (only a residential-only Building certification), EV charger circuit work anywhere within Hardin city limits -- residential or commercial -- requires an Electrical Permit issued directly by the Montana DLI Building Codes Bureau in Helena, not by the City of Hardin, under the 2020 NEC. The state's Application for Residential Electrical Permit (Rev. 11/25) has no dedicated EV/EVSE line item -- it lists an 'Alternative Energy' line (K, $45) that only covers Solar/Wind/Hydro generation, not vehicle-charging loads. A single EV charger circuit added to an existing home instead falls under line H, '1 additional circuit or piece of equipment' ($45), the same category used for a hot tub or A/C circuit.
Verified 2026-07-20 · Source
Requirements
- Electrical permit issued by the Montana DLI Building Codes Bureau (Helena), not the City of Hardin, per Title 50, Chapter 60, Section 604 MCA and ARM 24.301.431
- No EV/EVSE-specific line item exists on the state's Residential or Commercial Electrical Permit application -- do NOT check the 'Alternative Energy Source' box, which is scoped to Solar/Wind/Hydro generation systems, not EV charging
- A single charger circuit added to an existing single-family home falls under line H, '1 additional circuit or piece of equipment'

Sign Regulations Compliance (No Standalone Sign Permit Published)
VerifiedHardin City Code 11-1-8-3 (Sign Regulations, part of Title 11 Zoning, Chapter 1) establishes substantive size, placement, and attachment standards for signs by zoning district. Direct review of the City's Permits/Forms page (which lists every downloadable PDF form the City publishes) and the general Application For Building Permit's Type of Work checkbox list found no standalone sign-permit application, fee schedule, or dedicated form -- an honest publication gap, not an invented omission. Sign compliance in Hardin appears to be enforced through the City's general, complaint-driven Code Enforcement process rather than a proactive permit-application gate.
Verified 2026-07-22 · Source
Requirements
- R District: churches, public and semi-public buildings, hospitals, and institutions may have one bulletin board not more than fifteen (15) square feet in area
- R District: temporary signs pertaining to lease or sale of premises must not exceed ten (10) square feet; nonilluminated nameplates must not exceed one (1) square foot (an R2 District nameplate may be up to four (4) square feet)
- C Districts: total sign area on a premises may not exceed two (2) square feet of sign for each lineal foot of street frontage of that premises
- C Districts: every sign must be either (1) attached to a building and not extending more than five feet (5') over the property line, or (2) located wholly on privately owned property without extending over the property line or any adjacent right of way, or (3) approved in writing as an encroachment by the City Council
- No City-published sign-permit application, fee, or standalone review process was found; confirm current requirements directly with the City before installing a sign in a C District, since the encroachment-approval path (option 3 above) requires City Council action
Required documents
- OptionalNo dedicated Sign Permit application publishedNot among the PDFs listed on the City's Permits/Forms page (hardinmt.com/Permits-Forms.html) as of this review; a wall-mounted commercial sign's attachment method could plausibly fall under the general Application For Building Permit's 'Other' Type of Work checkbox, but this is not stated anywhere in the Sign Regulations ordinance itself and is not confirmed as a requirement

Fire Sprinkler (Fire Suppression) and Fire Alarm Permit
VerifiedHardin holds no Montana DLI certification in Fire (its only certification is Building (B), RESIDENTIAL ONLY) and has no local Fire Marshal -- confirmed there is no dedicated, separately-fee-scheduled 'Fire Sprinkler/Alarm Permit' product published by the City. Fire SUPPRESSION (sprinkler) work is instead processed through the same general Application For Building Permit used for all other Hardin building work: 'Fire Suppression' is an explicit Type of Work checkbox on both the City's own form and the underlying Montana BCP-1 statewide template it is based on (confirmed by direct read of the current PDF) -- residential-scope sprinkler work goes to the City (Joe Connelly / Nathan McConnell), commercial-scope sprinkler work goes to the state DLI Building Codes Bureau in Helena, mirroring the same residential/commercial split as Hardin's other building permits. Fire ALARM system wiring has no dedicated line item on either the current Montana Residential or Commercial Electrical Permit fee schedules (confirmed by direct read of both PDFs) and, since Hardin holds no Electrical certification at all, is billed under the same general state Electrical Permit valuation/circuit-based fee tiers as any other electrical work. Montana has adopted the 2021 International Fire Code statewide via ARM 23.12.601, administered by the Montana DOJ Office of the State Fire Marshal (not the DLI Building Codes Bureau) -- but direct review of the State Fire Marshal's own 'Fire Prevention and Investigations' page shows its published functions are inspection certification, code-adoption assistance, and fire investigation, not a separate SFMO-issued sprinkler/alarm permit with its own fee schedule comparable to larger Montana cities' locally-issued fire-alarm-and-sprinkler permits (e.g. Great Falls). No such Hardin-specific or SFMO-specific fire permit fee was found published.
Verified 2026-07-22 · Source
Requirements
- Fire suppression (sprinkler) work: check the 'Fire Suppression' box under Type of Work on the Application For Building Permit -- submit to the City of Hardin Building Department for residential-scope work, or mail to the Montana DLI Building Codes Bureau (PO Box 200517, Helena, MT 59620-0517) for commercial-scope work, since Hardin's certification does not cover commercial building work
- Fire alarm system wiring: apply for a state Residential or Commercial Electrical Permit (Hardin holds no Electrical certification of any project type) -- there is no dedicated 'fire alarm' line item, so the fee is calculated from the same general valuation/circuit-based tiers used for any other electrical work
- Commercial/public-building fire protection systems are subject to the 2021 International Fire Code as adopted statewide by Montana (ARM 23.12.601), administered by the Montana DOJ Office of the State Fire Marshal
- No separate Hardin-specific or Montana State Fire Marshal-specific sprinkler/alarm permit application or fee schedule was found published -- confirm current requirements directly with the City Building Department and, for commercial projects, the Montana Building Codes Bureau and/or Office of the State Fire Marshal

Change Of Use Permit (No Standalone Certificate Of Occupancy)
Verified'Change of Use' is an explicit Type of Work checkbox on the same general Application For Building Permit used for all other Hardin building work (confirmed by direct read of the current PDF) -- there is no standalone change-of-use application, fee, or Certificate of Occupancy document published separately by the City. The form additionally requires a mandatory free-text 'detailed description of the project use and occupancy... before application is accepted' regardless of which Type of Work box is checked. For residential property, submit to the City of Hardin Building Department under Hardin's residential Building certification; for commercial property, Hardin's certification does not cover commercial building work at all, so a change-of-use submission routes to the Montana DLI Building Codes Bureau's BCP-1 Building Permit/Plan Review Application in Helena instead (same 'Change of Use' checkbox), consistent with this corpus's existing commercial-building-permit-state entry for Hardin. No dedicated 'Certificate of Occupancy' form or process was found among the City's downloadable Permits/Forms PDFs.
