Tips

  • Washington City uses its own current, ICC-style valuation-based Building Permit Fee Table — this is NOT the same as St. George's or unincorporated Washington County's 1997 Uniform Building Code fee scale, despite all three jurisdictions sharing the same county.
  • New Single Family and New Commercial permits go through Washington City's 'Packet Review' process: all reviewing departments (building, planning, power, public works, fire) review concurrently in the CityInspect portal, and corrections must be viewed (not edited) until all departments have completed their pass.
  • Construction hours in Washington City are 6am–10pm Monday through Sunday, with a 3am start time allowed for concrete pours from April through October.
  • Plan review fee is 45% of the calculated building permit fee, per Washington City's own fee schedule — confirm this differs from neighboring St. George's 65% rate before assuming parity.
