Tips

  • Northglenn amended the adopted IPC's minimum sewer depth to 12 inches and gas test pressure to 10 PSIG — confirm these local figures rather than assuming unamended IPC defaults.
  • Water heater installation/replacement is its own One-Stop/Quick Permit line item in CommunityCore, not folded into a general plumbing permit — apply under the correct specific permit type to avoid delay.
