Full Breakdown

Lafayette City-Parish Consolidated Government Code § 89-90(b)(2)f exempts window signs from the sign-permit requirement, but only if the combined area of all temporary and permanent window signs stays at or under 50% of the window's total area. This rule sits inside Sec. 89-90, the Development Code's sign section, which by its own terms in subsection (a)(1) applies only within the City of Lafayette, not the unincorporated parish, and not Broussard, Carencro, Duson, Scott, Youngsville or Milton, which set their own sign rules. DPD administers sign permits and enforcement citywide.

Violations & Fines

Exceed the 50% window-sign cap and the display loses its no-permit exemption; DPD can require a sign permit or order removal, with Code violations punishable by up to $500 and six months under Sec. 1-9.

Frequently Asked Questions

Do I need a permit for a window sign in Lafayette?
No, as long as your combined temporary and permanent window signs cover 50% or less of the window's total area. Exceed that and the sign no longer qualifies for the no-permit exemption.
Does this 50% window-sign rule apply outside the City of Lafayette?
No. Sec. 89-90(a)(1) limits this sign section to the City of Lafayette; the unincorporated parish and towns like Broussard or Youngsville set their own rules.
