When you need this permit
- Electrical connection requires a Trade Permit Application (electrical) issued by the City of Whitefish under the 2020 NEC, since Whitefish is DLI-certified for electrical (E) permitting

Tips
- No standalone Solar-PV-specific application or fee schedule (of the kind Billings publishes) was found on the City of Whitefish's site — solar installations are processed through the standard Trade Permit Application (electrical) plus a Building Permit Application (structural mounting).
- Because Whitefish is DLI-certified for electrical permitting, both the electrical and structural halves of a solar project are handled entirely by the City — no separate state Building Codes Bureau application is needed (unlike in a partially-certified city such as Havre).
- reviewTimelineDays is null (hard-unpublished): solar PV is processed through the standard Trade Permit (electrical) plus a Building Permit (structural mounting), neither of which has a City-published review turnaround (checked the Building Permits / Inspections page, Planning & Building page, FAQ, fee schedule, and Citizen Portal); City Code 10-1-4/10-1-1 sets no review-day period. Both halves are reviewed by the City (DLI-certified for B and E), so the state DLI 'three weeks' state-administered figure does not govern. No real governing figure was found after exhausting the city site, city code, and MT DLI. Contact Planning & Building at (406) 863-2410 for current review timelines.
