EV Charger / EVSE Permit in Silverthorne, Colorado

Silverthorne has no distinct electric-vehicle-charging-station permit type or fee line-item. As with all other electrical work in Town, an EV charger (EVSE) circuit is permitted and inspected entirely by the Summit County Building Department, not the Town of Silverthorne — the Town does not intake, fee, or issue electrical permits at all. Summit County's published Building Permit Fee Schedule has no separate EV/EVSE line-item; EV charger installs are billed under the same square-footage/dwelling-unit-based Electrical Permit Fee tiers used for any other electrical circuit addition (same fee mechanism documented in this file's Electrical Permit entry). Summit County's population (~30,000) exceeds the 20,000-population threshold in Colorado HB24-1173, meaning the County was required to adopt, by 12/31/2025, an ordinance either adopting the Colorado Energy Office's EV Charger Permitting Model Code, establishing its own objective EV-charger permitting standards, or affirming continued use of its existing review process — no County ordinance or public confirmation of which of the three compliance paths Summit County chose was located as of this review.

When you need this permit

  • EV charger (EVSE) circuit/panel work must be submitted directly to the Summit County Building Department (37 S.C.R. 1005, Frisco, CO), not to the Town of Silverthorne, per the same Outside Agency Permits routing documented for all electrical work in Town
  • Governed by the 2023 NFPA 70 National Electrical Code as adopted (same code cited in this file's Electrical Permit entry)
  • No EV/EVSE-specific line-item appears on Summit County's published Building Permit Fee Schedule; the general residential Electrical Permit Fee (based on total building area and number of dwelling units) applies
  • Summit County (population >20,000) is a 'covered county permitting agency' under Colorado HB24-1173 (effective 8/7/2024), obligated by 12/31/2025 to adopt an ordinance addressing EV-charger permit standards — no public confirmation of the County's chosen compliance path (model code adoption, custom standards, or status-quo affirmation) was located in this review; this is reported as a genuinely open point rather than assumed

Tips

  • Do not submit an EV charger electrical permit through the Town of Silverthorne's SmartGov portal or Building Division — it will not be processed there. Contact the Summit County Building Department directly at (970) 668-3170.
  • Because Summit County's fee schedule has no distinct EV/EVSE line-item, budget for the general residential Electrical Permit Fee (area- and unit-count-based) rather than a flat EV-specific fee.
  • Summit County is large enough to be covered by Colorado's HB24-1173 EV-charger-permitting law (population threshold >20,000), but this review could not confirm which of the three statutory compliance options the County chose by the 12/31/2025 deadline — call ahead to ask whether a streamlined EV-charger review track now exists beyond the standard Electrical Permit process.
