Do You Need a Permit to Replace a Water Heater in Denver?
Permit required
Denver requires a permit for water heater replacement and handles it through its Quick Permits program — water heaters are explicitly listed as allowed plumbing quick-permit work for single-family and duplex homes.

What to know
- Apply through Denver's e-permits system; quick permits for equipment replacement in existing homes need no plan review.
- For replacements in existing buildings, no pre-existing construction permit is required (that requirement applies to new construction/additions).
- Gas-fired water heaters in multifamily and commercial buildings carry additional feasibility-assessment requirements — single-family replacements are the simple path.
