  • Water/Sewer Line Upgrade inspections are scheduled differently from most other Johnstown permits: 24 hours prior by email to BuildingPermits@johnstownco.gov, Monday-Thursday 8 AM-4:30 PM and Friday 8 AM-10:30 AM, rather than the standard 4 PM-prior-day phone/Safebuilt-website process used for other trades — confirm the correct scheduling channel for your specific permit type.
  • Water heater/boiler permits require the unit's gallon capacity or BTU rating on the application — have this ready before applying to avoid delay.
