Salt Lake City ADU Permit Fees & Cost Calculator
Salt Lake City allows accessory dwelling units, but the official city sources provided here do not publish a single ADU-specific fee schedule. The best-supported items are the city's building-services ADU guidance and a city predevelopment/process source; exact permit, plan-check, and utility connection fees still need verification from the current city fee schedule and Salt Lake City Public Utilities.
