Tips

  • Freestanding and monument signs need a stamped engineered drawing for wind/snow load — budget extra design lead time versus a simple wall sign.
  • Real estate, political, and 72-hour garage sale signs are exempt from a permit but must still follow the Chapter 17.96 size/placement rules.
  • Casper publishes no dedicated sign-permit fee line; based on the Signage page's own instruction to file a combined 'building and sign permit application,' expect it billed off the same combined valuation-based fee table (starting at the $35 Initial Building Permit Fee) used for every other Casper permit type in this file — confirm the exact cost with Community Development at (307) 235-8254 before applying.
