Tips
- Hamilton is a Montana DLI-certified jurisdiction for electrical (E) permitting — permits are issued locally by the Building Department, not the state, within city limits.
- Fees for a new single-family dwelling scale by amperage: $200 for up to 200 amp service, up to $800 for 601+ amp service.
- A dedicated review-timeline figure specific to electrical permits was not separately published; the 10-working-day figure verified for the Roof Permit and the up-to-10-day figure for Residential Building Permits are the only Hamilton-specific timelines found. Applied here as the governing departmental figure since all Building Department permit types route through the same Planning/Public Works/Building Official approval chain described on the Residential Building Permit Application; flagged reviewTimelineVerified:false pending a permit-type-specific confirmation.
