Signs and Advertising Louisiana 3 Minutes Read · published February 09, 2026 Flag of Louisiana

New Orleans, Louisiana property owners and businesses within locally designated historic districts must follow specific sign design standards and an approval process administered by the Historic District Landmarks Commission and the Department of Safety and Permits. These standards cover sign size, materials, mounting, illumination, and placement to protect historic character; official guidance and sign illustrations are published by the city [1]. Applications, required forms, and submission instructions for Certificates of Appropriateness and related sign permits are published by the historic preservation office [2]. Sign permit filing, plan review, and inspection are handled through the Department of Safety and Permits permit channels [3].

Overview of Sign Design Standards

The city emphasizes compatible materials, minimal visual clutter, and reversible mounting that avoid damage to historic fabric. Typical design rules address:

  • Proportions and maximum area relative to building façade.
  • Allowed attachment methods to masonry and storefronts to prevent irreversible damage.
  • Restrictions on moving or altering historic signboards, neon, and painted wall signs.
  • Controls on illumination type, intensity, and direction to reduce visual intrusion.
Always document existing conditions with photographs before submitting an application.

Penalties & Enforcement

Enforcement of sign regulations is carried out by the Historic District Landmarks Commission and the Department of Safety and Permits through administrative review, notice, and, if necessary, civil enforcement. Specific monetary fines and schedules are determined by city ordinance and permit rules; where amounts are not presented on the cited guidance pages, the amount is not specified on the cited page [1].

If cited for an unauthorized sign, do not remove evidence until advised by the enforcing office.

Applications & Forms

Most historic-district sign projects require a Certificate of Appropriateness (COA) or a sign permit submitted through the historic preservation application process. Common items listed by the city are application forms, site photos, scaled drawings, proposed materials, and mounting details [2]. Fee amounts, form numbers, and precise submission checklists may be on the applications page or on permit portals; if a fee or form number is not published on the official page, it is not specified on the cited page.
