Codes adopted
Blackfoot Municipal Code 10-1-1 ('Administrative Code Adopted; Building Department Established') adopts 'the administrative code, current edition as adopted by the state ... published by the International Conference Of Building Officials,' for administration, organization, and enforcement of the technical codes governing site preparation and construction within the city. (2003 Code sec 4-01-01; amd. 2012 Code).

Source: Blackfoot Municipal Code 10-2-1, American Legal Publishing (codelibrary.amlegal.com/codes/blackfootid/latest/blackfoot_id/0-0-0-4470).Both codified sections tie the city's adopted building/residential code editions to whatever edition 'is adopted by the state' at any given time (i.e., the Idaho Building Code Board / DOPL Building Safety Program's statewide-adopted IBC/IRC cycle under the Idaho Building Code Act, Idaho Code Title 39, Chapter 41), rather than freezing a specific year in the municipal code text itself. No City of Blackfoot source was found stating a specific current IBC/IRC/IECC edition year independent of this 'as adopted by the state' language.The City's own Residential Building Permit Application / Residential Plan Review Checklist (PDF, cityofblackfoot.org/DocumentCenter/View/89) states plans are to be designed to the '2012 IRC Code & 2012 IECC (with Idaho amendments)' -- however this document appears to be a reused/adapted template (it also references 'Twin Falls Highway District,' 'SUI zone,' and 'Twin Falls' designated flood plain areas,' which are not Blackfoot or Bingham County features), so its cited 2012 IRC/IECC edition year is treated as potentially stale/templated rather than authoritative, and is superseded per Municipal Code 10-2-1's 'current edition as adopted by the state' language. Flagged rather than relied upon for the codesAdopted edition year. Source: City of Blackfoot Residential Building Permit Application (PDF).Idaho Division of Occupational and Professional Licenses (DOPL), Building Safety Program, administers the statewide building code framework (Idaho Building Code Act, Idaho Code Title 39, Chapter 41) and issues HVAC/mechanical, electrical, and plumbing permits directly for jurisdictions that have not assumed those trades locally. Source: DOPL Building Safety Program overview (dopl.idaho.gov/bld/) and DOPL Permits portal (dbs.idaho.gov/permits/, redirects to dopl.idaho.gov).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. Source: City of Blackfoot Permits & Applications page (cityofblackfoot.org/166/Permits-Applications).CONFLICT NOTE (flagged, not resolved by inference): The City of Blackfoot's own Fee Schedule (Resolution No. 425, effective October 1, 2025) contains detailed 'MECHANICAL PERMITS,' 'ELECTRICAL PERMITS,' and 'PLUMBING PERMITS' fee sections with itemized city-charged fees for HVAC units, gas lines, residential/commercial electrical services, and residential/commercial plumbing -- which appears to directly contradict the Permits & Applications page's statement that all HVAC/electrical/plumbing permit applications are 'acquired through the State of Idaho.' Both documents are official City of Blackfoot publications and both were independently verified to resolve/load. This file does not guess which document is authoritative or stale; it reports the Permits & Applications page's explicit routing statement as the department's self-described intake process (consistent with the prior research finding), while separately publishing the Fee Schedule's mechanical/electrical/plumbing fee tables as-is as City-published figures, and flags this discrepancy for a human to resolve with the Building & Safety Department directly at (208) 812-4198.

Any walls exceeding 10 feet tall are not prescriptive wall bracing and are required to be engineered for shear.' Source: City of Blackfoot Residential Building Permit Application (PDF).

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 appear (per a flagged, unresolved conflict) in the City's own Fee Schedule for these same trades.

Requirements
- Electrical, mechanical (HVAC/gas line), and plumbing permit applications for work in Blackfoot are obtained through the State of Idaho at https://dbs.idaho.gov/permits/, per the City's own published statement
- 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
