Tips

  • A sign permit in Silverthorne requires an approved Comprehensive Sign Plan on file for the property FIRST — if your building doesn't already have one, budget time to compile and submit it under Sec. 4-9-13 before your individual sign permit can be approved.
  • The $2/sq ft sign fee is based on total sign area, so get an accurate area measurement (not just face dimensions) before budgeting.
  • Banners are billed weekly ($15/week, up to 18 weeks/year) and capped at 32 sq ft, one per address — a materially different fee mechanism from the per-square-foot permanent sign fee.
