Lafayette, LA Special Events & Permits: Block Party Permits (2026)

Lafayette's block-party and temporary-closure rule sits in Chapter 78's traffic-control article as Sec. 78-266, applying city-wide and in the unincorporated parish alike. Anyone planning an activity or function that will impede vehicular or pedestrian traffic on or adjacent to a public street and requires a partial or full right-of-way closure must get a permit from the director of the department of traffic and transportation. The application must be filed at least five working days before the first day the applicant wants to close or block the roadway, and must include the applicant's contact information, the on-site contact person, the dates and hours sought, an indemnification statement, a barricading layout, a description of the activity, and a petition showing whether directly affected property owners approve or object, plus sign-off from the police and fire departments before the director can approve it.

The director must decide within five working days of a complete application and can deny it for reasons including inadequate emergency-vehicle access, unacceptable impact on nearby traffic or transit, or insufficient justification for the closure weighed against nearby residents and businesses. Recognized, repetitive holiday functions, the ordinance names Mardi Gras and Festival International as examples, are excused from the application step entirely. Everyone else is bound by the street-classification limits in subsection (d): arterials on the adopted Thoroughfare Plan may only close for holidays/festivals or for 2-4 hour parades and special functions; collector streets get up to eight hours; and minor streets, alleys, and sidewalks, the block-party category, are capped at eight-hour closures for resident-involving promotional functions. Interstate and state routes are off-limits entirely, since they fall under the Louisiana Department of Transportation and Development, not city-parish authority.
