When you need this permit
- Structural/mounting component requires the general Building Permit Application (Class of Work: New or Addition), with plans demonstrating the roof or ground-mount structure can support the additional load under the City's 55 lb snow load / 115 MPH wind design criteria
- Electrical interconnection requires the general Electrical Permit Application; no dedicated 'Alternative Energy Source' line item (unlike the state's own Residential Electrical Permit form used in non-certified Montana jurisdictions) appears on Columbia Falls' Electrical Permit Application, so the applicable base electrical work-type fee (e.g., Type B Interior Rewire/New Addition) is understood to apply
- No dedicated solar-specific application, checklist, or fee schedule was found published by the City after exhaustive search of the DocumentCenter, site search, and Forms & Permits listing; confirm the correct electrical fee category and any additional requirements with the Building Clerk, (406) 892-4432, before submitting
