Do I need a permit for water heater replacement in Aurora?
Yes. In Colorado, water heater replacement generally requires a permit, and Aurora is no exception.
Colorado's State Plumbing Board requires a state plumbing permit and inspection for residential water-heater installation and replacement, and there is no exemption from the permit even when the homeowner does the work themselves. Switching between gas and electric, relocating the unit, or moving to a tankless system usually adds electrical, gas, or venting work and additional permits and review. Aurora requires a permit to install or replace a residential water heater, even for a like-for-like swap, applied for through the Aurora4Biz portal (aurora4biz.org). The work is reviewed under the 2021 International Plumbing Code and, for gas units, the 2021 International Fuel Gas Code that Aurora enforces, so venting, expansion tank, and relief valve details are checked at inspection. Switching between gas and electric or moving to a tankless unit usually adds electrical, gas, or venting work and additional trade permits, so confirm scope with the Building Division.
