Codes adopted
The City of Rexburg operates its own Building Department, which handles ALL trade permitting (building, mechanical, electrical, plumbing, and fire) in-house — it is not a DOPL-administered jurisdiction for permit issuance. The Building Official 'enforces and interprets the building code,' 'supervises the mechanical, electrical, plumbing, and fire inspectors,' and the Building Department's stated scope explicitly covers mechanical, electrical, and plumbing programs as sub-programs of the Building Department itself, each with dedicated per-discipline permit fees.

VerifiedRequired for all photovoltaic (solar panel) work within Rexburg city limits, using the City's own dedicated 'Solar Panels / Cell Tower' application. Unlike most Idaho cities, Rexburg's Building Department self-administers electrical permitting directly (it is not a DOPL-routed jurisdiction), so both the structural and electrical scope of a solar install are handled in-house by the City.

EV Charging Station Permit (City Electrical Permit)
VerifiedRequired for installation of a Level 2 (or higher) electric vehicle charging station/EVSE within Rexburg city limits. Unlike most Idaho cities in this dataset, which route electrical permitting through the State of Idaho DOPL, Rexburg's Building Department self-administers electrical permitting directly (the same finding this file's solar-pv-permit entry documents), using its own 'Mechanical, Electrical or Plumbing Miscellaneous' permit application for installation/upgrade work that is not part of new construction.

Requirements
- Submit the City's Mechanical, Electrical or Plumbing (MEP) Miscellaneous Project application via the Rexburg Public Permit Application Portal (apply.rexburg.org/publicapp)
- Electrical connection work is governed by the 2023 NEC (including Article 625, Electric Vehicle Power Transfer System) as adopted by the City and is inspected by the City's own dedicated electrical inspector, not Idaho DOPL
- A dedicated branch circuit sized to the EVSE manufacturer's specifications is required; GFCI protection applies per NEC 625 where the EVSE is cord-and-plug connected
- If the charger install requires a panel/service upgrade or accompanies new construction, that scope is submitted with the applicable new-construction Building Permit application instead of the standalone MEP Misc. application

| MEP Miscellaneous Project Permit Fee (Electrical) — closest published category for an EV charger circuit | No dedicated dollar figure for EV charger/EVSE circuits is published on the City's Building Permit Applications page, Electrical Information page, or either residential Fee Estimator — consistent with this file's solar-pv-permit entry's identical finding that the standalone MEP Misc. Project fee is not published as a static figure online. Third-party permit-cost aggregators (not a primary source) estimate Rexburg electrical permits generally in the $37-$450 range depending on project scope and valuation.
