Do I need a permit for water heater replacement in Littleton?
Yes. In Colorado, water heater replacement generally requires a permit, and Littleton is no exception.
Littleton issues plumbing and mechanical permits through eTRAKiT and enforces the 2024 International Plumbing Code and 2024 Fuel Gas Code, so water heater replacements require a permit. Tank and tankless changeouts, including gas and venting, are inspected by the city. Confirm the correct permit type with the Littleton Building Division. 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.
