Tips
- A single-family 100-300 amp service fee ($182) and 301+ amp fee ($280) each include a maximum of three inspections — plan your rough-in and final inspections accordingly.
- If electrical work begins before a permit is obtained and fees paid, Helena doubles the fee amount before the permit will be issued.
- Commercial/industrial electrical fees are a percentage-of-installation-cost formula (declining marginal rate from 8.4% down to 0.42%), not a flat valuation table like the building permit schedule.
