Do I need a permit for water heater replacement in San Antonio?
Yes. In Florida, water heater replacement generally requires a permit, and San Antonio is no exception.
Whether a water heater swap needs a permit depends on your jurisdiction and the unit. Some jurisdictions exempt a small like-for-like electric replacement, while others require a plumbing permit for any change-out. Any gas water heater, any increase in size or wattage, or any relocation triggers a plumbing or gas permit almost everywhere.
