Quick Answer: Are Permits Needed for Water Heater Replacements in Greeley, CO?

Yes. In Greeley, replacing a water heater typically requires plumbing and gas permits, with mechanical approval for gas-fired units. There are very few exemptions, so pull the permit before work begins (we handle this step for you, so no need to worry about permits if you’re hiring us).

Local Permit Requirements in Greeley, CO

  • Greeley has officially adopted the 2021 International Codes (with local amendments).
    • The City of Greeley updated its Municipal Code to incorporate the 2021 International Codes, replacing the older 2018 editions.
  • These adopted codes form the foundation for permitting and inspections in Greeley.
    • The City’s Building Inspection Division enforces these codes when reviewing and approving permits.
  • Aside from a few exceptions, a permit is generally required when you replace parts of regulated systems.
    • Greeley’s permitting rules require that any work involving the installation, repair, removal or replacement of electrical, gas, mechanical, or plumbing systems must have a permit before work begins. 
    • This includes things like water heaters because they connect to plumbing and/or fuel gas systems. 

Exemptions and Special Cases

Inside Greeley city limits, exemptions are limited because the City’s baseline rule is that replacing regulated plumbing, gas, mechanical, or electrical systems requires you to apply and obtain the required permit through Building Permits and Inspections.

A few situations to know:

  • Unincorporated Weld County: Weld County publishes a specific exemption list where replacement of existing gas or electric water heaters is listed as work that does not require a building permit (in unincorporated areas), while noting that other permits can still apply depending on the work. See Weld County’s “Work Exempt from a Building Permit” document.
  • Homeowner installs: Weld County provides a homeowner pathway via a formal affidavit. If you are self-performing work, review the City’s Homeowner Affidavit for eligibility and restrictions.
