This is PermitBase’s published record for Blackfoot as of 2026-08-20. It has since been superseded — see the current record.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.

Note: the formerly-cited 'DOPL Permits portal' at dbs.idaho.gov/permits/ no longer resolves to a permits page — it redirects to the bare dopl.idaho.gov homepage, consistent with DOPL's dbs.idaho.gov-to-dopl.idaho.gov domain migration. The current pages for purchasing Electrical, HVAC, and Plumbing permits are dopl.idaho.gov/ele/, dopl.idaho.gov/hvac/, and dopl.idaho.gov/plb/ respectively, each carrying a 'Purchase a[n] [Trade] Permit' button linking to DOPL's shared ArcGIS-based online permit tool (idaho.maps.arcgis.com/apps/instant/sidebar/index.html?appid=c568d3c03d5f43f0841dcfa9c2a9537e).The City of Blackfoot's own Permits & Applications page states verbatim: 'All HVAC, Electrical and Plumbing permit applications are acquired through the State of Idaho at https://dbs.idaho.gov/permits/.' This directly confirms the prior research's claim that Blackfoot routes mechanical (HVAC), electrical, and plumbing permitting to the state DOPL system rather than self-administering those trades -- the City issues and reviews only the Building Permit (and related general permits: demolition, retaining wall, mobile home block-set, roof repair, fence) itself.

Both documents are official City of Blackfoot publications, and neither is treated here as superseding the other: the Permits & Applications page's explicit routing statement is reported as the department's self-described intake process, the Fee Schedule's mechanical/electrical/plumbing fee tables are published as-is as City-published figures, and the discrepancy should be resolved with the Building & Safety Department directly at (208) 812-4198.

Electrical / Mechanical (HVAC) / Plumbing Permit -- Routed to State of Idaho DOPL
VerifiedPer the City of Blackfoot's own Permits & Applications page, electrical, mechanical (HVAC), and plumbing permit applications within Blackfoot city limits are acquired directly through the State of Idaho Division of Occupational and Professional Licenses (DOPL) Building Safety Program, not through the City Building Department. This entry documents the state-level routing and the itemized City fee tables that the City's own Fee Schedule publishes for these same trades — an unresolved conflict between the two City sources.
Verified 2026-07-16 · Source
Requirements
- Electrical, mechanical (HVAC/gas line), and plumbing permit applications for work in Blackfoot are obtained through the State of Idaho, per the City's own published statement (the City cites https://dbs.idaho.gov/permits/, which redirects to the DOPL homepage rather than a working permits page; the current pages are https://dopl.idaho.gov/ele/, https://dopl.idaho.gov/hvac/, and https://dopl.idaho.gov/plb/, each with a 'Purchase a Permit' link to DOPL's shared online permit tool)
- DOPL administers statewide contractor/tradesperson licensing and, per this routing, permit issuance/plan review/inspection for these three trades within Blackfoot
- CONFLICT: the City of Blackfoot's own Fee Schedule (Resolution No. 425, effective 10/01/2025) separately lists detailed City-charged fee tables for Mechanical Permits (gas lines, HVAC units, residential $80/dwelling unit + $15/HVAC unit, commercial/industrial $80 + percentage of installation cost), Electrical Permits (temporary service $40, residential services $80/dwelling unit + $5/room, commercial/industrial $80 + percentage of cost, motor/generator/welder circuits by horsepower, electric signs), and Plumbing Permits (water/sewer lines $47/inspection, water heaters $47/inspection, residential $80/dwelling unit + $5/fixture, commercial/industrial $40 + percentage of cost) -- confirm directly with the Building & Safety Department at (208) 812-4198 whether the City has since assumed some or all of these trades, whether these fee tables are legacy/unused, or whether some subset of work (e.g., permits issued in conjunction with a City building permit) is still City-administered notwithstanding the general DOPL-routing statement

EV Charger / EVSE Installation Permit
VerifiedBlackfoot has no separate EV charger/EVSE permit category. The City's own Permits & Applications page states unambiguously: 'All HVAC, Electrical and Plumbing permit applications are acquired through the State of Idaho at https://dbs.idaho.gov/permits/' -- this resolves the routing question in favor of the State of Idaho Division of Occupational and Professional Licenses (DOPL), not the City. An EV charging circuit is billed under DOPL's published Electrical Permit Worksheet (Fee Schedule), 'Existing Residence' category, since it is added wiring to an existing dwelling rather than new construction.
Verified 2026-07-20 · Source
Requirements
- A new dedicated circuit or hardwired connection for an EV charging station is electrical work; per the City of Blackfoot's own published routing statement ('acquired through the State of Idaho'), electrical permit applications for work within city limits are obtained through DOPL (purchased online at dbs.idaho.gov), not the City Building Department
- No EV/EVSE-specific permit category or fee line was found published by DOPL
- The City's own Fee Schedule (Resolution No. 425, effective 10/01/2025) separately lists a City-charged Electrical Permit fee table (temporary service $40, residential services $80/dwelling unit + $5/room), but the City's own Permits & Applications page is explicit that electrical permit applications go through the State -- so the DOPL fee schedule is treated as governing here

VerifiedBlackfoot issues no separate solar-PV permit type; rooftop or ground-mounted PV is permitted as a City Building Permit (structural/racking, valuation-based fee table, per City Fee Schedule Resolution No. 425) plus an Electrical Permit for the wiring/interconnection portion. Per the City's own Permits & Applications page, electrical permit applications are acquired through the State of Idaho DOPL Building Safety Program rather than the City — though the City's own Fee Schedule separately publishes a City-charged electrical fee table for the same trade, an unresolved conflict noted under the Electrical/Mechanical/Plumbing (state-routed) permit entry.
