Tips

  • Washington City groups common trade swaps (generators, water heater replacement, HVAC equipment upgrades, electrical meter upgrades, gas line additions) into a single 'Simple Permit' application category rather than requiring separate electrical/plumbing/mechanical permit types — confirm which of 'Electrical', 'Gas Line', or 'Plumbing' best matches your project when applying.
  • Photos of the current/existing equipment are a required upload for Simple Permits in Washington City, in addition to manufacturer specs for the new equipment.
  • EV charger (EVSE) installation is treated as standard electrical work under this same Simple Permit — the city's official Simple Permit Requirements page (washingtoncity.org/development/building/simplepermit, live-checked 2026-07-19) instructs applicants to select 'ELECTRICAL' as the permit type and lists example projects (generators, water heater replacement, HVAC equipment upgrades, electrical meter upgrades, gas line additions) with no distinct EV-charger or electric-vehicle-charging category or fee tier; assessed on the same valuation-based Building Permit Fee Table as other Simple Permit work.
