Land Use and Zoning Louisiana 4 Minutes Read · published February 09, 2026 Flag of Louisiana

New Orleans, Louisiana preserves its historic neighborhoods through a formal review process for exterior alterations and offers programs that can make rehabilitation more viable. This guide explains how the Historic District Landmarks Commission (HDLC) review works, what incentives may be available for certified rehabilitation, and how enforcement, permits, appeals, and applications are handled in the city. For official procedures and applications consult the HDLC pages and federal tax credit guidance linked below.[1]

Overview of Historic Alteration Review

The Historic District Landmarks Commission reviews proposed exterior changes in designated historic districts and to landmark properties to ensure compatibility with preservation standards. Projects that change significant facades, roofs, windows, porches, or building footprints typically require a Certificate of Appropriateness (COA) or a permit issued after HDLC review.[2]

Obtain guidance early: preliminary advice can reduce rework at formal review.

Incentives for Preservation and Rehabilitation

Property owners may combine local review with state and federal incentives for historic rehabilitation. The federal Historic Tax Credit program administered by the National Park Service is a common incentive for income-producing properties; local or state incentives vary and should be confirmed with the issuing agency.[3]

Penalties & Enforcement

The HDLC and City enforcement pathways address unapproved alterations, failure to obtain required COAs, and violations of conditions imposed by a COA.

  • Enforcer: Historic District Landmarks Commission (HDLC) and City of New Orleans enforcement officers; official contact available on the HDLC site.[1]
  • Fines: fine amounts and schedules are not specified on the cited HDLC page or COA guidance pages; see cited municipal sources for any statutory fines.[2]
  • Escalation: whether penalties escalate for repeat or continuing offences is not specified on the cited page.
  • Non-monetary remedies: orders to restore or remove unapproved work, stop-work orders, and court enforcement actions are the typical municipal remedies though specific remedies or procedures are not specified on the cited pages.
