Water heater building permit

In an effort to address climate change, we encourage you to replace water heaters with electric heat pump water heaters. Learn about Piedmont’s electrification rebates and resources.

For exterior units, your project needs to meet Design Review Exemption #14:

  • Ground mounted
  • Only unit on property
  • Not in setback or visible from the street

If this exemption is not met or there is more than one exterior unit on site that is existing or proposed, the project requires design review approval first. This includes exterior tankless water heaters, exterior storage heat pump water heaters, exterior split condenser water heaters.
