CONFLICT NOTED 2026-07-16: the City's now-deleted Solar Photovoltaic (PV) Permit webpage stated a solar-specific carve-out — 'all solar revisions will be charged a minimum charge of one half hour at $37.50 per revision submitted' — which is more favorable than the fee schedule's one-hour minimum. That carve-out was verified live as recently as the 2026-03-08 archived capture but appears on no current live source, and the live fee schedule states a one-hour minimum; whether the City still honors the half-hour solar minimum cannot be verified now. Confirm with the Building Division (303-661-1451) before quoting a revision fee. |
EV Charger / EVSE Permit
VerifiedElectric vehicle charging equipment (EVSE) installation in Lafayette is processed as ordinary electrical work under the City's 'Quick Permit' category (Electrical, excluding Solar or projects with engineered plans), governed by the 2023 NEC as adopted. The City's Building Permit Fee Schedule (Exhibit A, effective 1-1-26) lists a flat $100 fee only for a specific named list of residential categories (AC, Furnace, Fence, Roof, Sewer Repair, Shed, Siding, Solar PV, Water Heater, & Windows) — EV chargers/EVSE are NOT on that list, so a standalone EVSE circuit is billed under the general valuation-based fee table instead. Under Colorado's HB24-1173 (Electric Vehicle Charging System Permits Act), Lafayette qualifies as a 'covered municipality' (population over 10,000) and was required to take a compliance action by December 31, 2025; the City adopted Resolution No. 2025-74, electing to continue using its existing permitting review process rather than adopting the Colorado Energy Office's EV charger model land use code or a new expedited standards/review process.
Verified 2026-07-20 · Source
Requirements

- Contractors must hold a current Colorado Electrical Board (DORA) State Master License and State Contractor License, plus a City of Lafayette Electrical Contractor License (no City license fee)
- No dedicated EVSE fee line exists on the Exhibit A fee schedule — EV chargers are not among the flat-$100 residential categories (AC, Furnace, Fence, Roof, Sewer Repair, Shed, Siding, Solar PV, Water Heater, & Windows), so the general valuation-based Building Permit Fee table applies
- Under HB24-1173, Lafayette (a 'covered municipality') adopted Resolution No. 2025-74 on or before the December 31, 2025 statutory deadline, electing to continue its existing permitting review process for EV charging system permits rather than adopting the state's model land use code or new statutory standards

Solar Thermal Permit
Required for solar thermal (hot water/hydronic) system installations in Lafayette.
