Electric Vehicle (EV) Charging Station Permit in Thornton, Colorado

The City of Thornton tracks 'Electric Vehicle Charging Station' as its own distinct permit subtype under the Electrical trade — confirmed directly against the City's own published monthly Building Permit Report (e.g., permits PREL202507941, PREL202600320, PREL202600400, PREL202600427, PREL202600434, issued January 2026), which lists 'Electrical / Electric Vehicle Charging Station / Residential' as a real, separately itemized permit category with its own valuations. There is no dedicated EV-specific dollar fee line on the City's published Fee Schedule; the permit is billed under the same valuation-based 'Other Permit Fees including Mechanical, Electrical, Plumbing' Electrical Permit Fee table documented in this file's Electrical Permit entry ($30.00 for the first $1,000 of trade valuation, plus $10.00 for each additional $1,000 or fraction thereof).

When you need this permit

  • Electrical Permit required for EV charging station installation, submitted through the CityView Portal or in person at City Development, per the same process documented in this file's Electrical Permit entry
  • Governed by the 2023 NEC (including NEC Article 625, Electric Vehicle Power Transfer System) as adopted and amended by the City — see codesAdopted
  • May qualify for the City's Rapid Review process, which targets processing and completing review of qualifying 'residential electrical or mechanical upgrades' within one business day, per the City's Building Permits & Inspections page
  • Trade valuation of the charger/circuit installation must be declared on the permit application — the Electrical Permit Fee is calculated from that valuation using the same tiered table as any other electrical work, since no EV-specific flat fee is published
  • Colorado state law (HB24-1173) separately restricts HOA/covenant limits on EV charging equipment and sets statewide baseline expectations for local EV charging permitting, though it does not itself set City of Thornton's fee amount

Tips

  • Thornton is one of the few jurisdictions in this coverage batch that visibly tracks EV charging stations as their own permit subtype in the City's own public permit-activity reports — a genuine, citable distinction, even though the dollar fee itself still runs through the general valuation-based Electrical Permit Fee table rather than a dedicated flat EV fee.
  • Ask specifically whether your EV charger installation qualifies for the City's Rapid Review process (target: complete review within one business day) — it is designed for exactly this kind of common residential electrical upgrade.
