Tips

  • Fort Collins uses the International Plumbing Code (IPC), not the Uniform Plumbing Code (UPC) used in Reno, NV — pipe materials and fixture requirements follow IPC.
  • The City — not a Colorado state board — issues and reviews plumbing permits in Fort Collins; the plumber must still hold the underlying State of Colorado plumbing license as a prerequisite for City Master Plumber registration.
  • Water heater replacement is processed as its own Fast-Track permit (see Mechanical/HVAC permit) at $65 per water heater, not under this Plumbing permit type.
  • Gas line installation for a heater is processed as a Mechanical permit, not a Plumbing permit, in Fort Collins.
