New Orleans City Departments and Agencies: Complete Directory

New Orleans operates under a consolidated city-parish government structure that merges municipal and parish functions into a single administrative framework, making the organizational chart of city departments more complex than in most American cities. This directory covers the major departments, independent agencies, and special-purpose bodies that deliver public services across Orleans Parish. Understanding which entity holds jurisdiction over a given function is essential for residents, businesses, property owners, and anyone seeking to navigate permitting, public safety, infrastructure, or social services. For broader context on how these departments fit within the overall governance structure, the site index provides a full map of topics covered across this reference.

Definition and scope

The City of New Orleans is a consolidated city-parish, meaning the City of New Orleans and Orleans Parish are governed as a single legal entity under a unified city charter. This consolidation, formalized through Louisiana state law, distinguishes New Orleans from neighboring parishes such as Jefferson Parish and St. Tammany Parish, which retain separate municipal and parish layers.

Within this consolidated structure, "departments and agencies" refers to 3 distinct categories of governmental bodies:

  1. Executive departments — Units directly under the authority of the Mayor's Office, headed by appointed directors and funded through the annual city budget.
  2. Independent boards and authorities — Bodies created by charter, state statute, or special legislation, which operate with varying degrees of autonomy from the Mayor. Examples include the New Orleans Sewerage and Water Board and the Regional Transit Authority.
  3. Criminal justice and court entities — Constitutionally or statutorily established offices that function independently of the Mayor, including the Orleans Parish Sheriff's Office, the District Attorney's Office, and the Orleans Parish Criminal District Court.

Scope limitations: This directory covers governmental bodies whose jurisdiction is coterminous with or contained within Orleans Parish. It does not cover state agencies that happen to operate offices in New Orleans (such as the Louisiana Department of Revenue), nor does it address federal agencies with a physical presence in the city. Regional bodies that span multiple parishes — such as the New Orleans Metro Area Regional Governance structures — are addressed separately.

How it works

The Chief Administrative Officer coordinates day-to-day operations across executive departments, serving as the administrative hub between the Mayor and individual department heads. The City Council, composed of 7 members (5 district seats and 2 at-large seats), exercises appropriations authority and legislative oversight over most executive departments through the budget process (City of New Orleans Home Rule Charter, Article III).

Independent oversight bodies operate parallel to, but not under, the executive branch. The Inspector General investigates waste, fraud, and abuse across city government. The Independent Police Monitor provides civilian oversight of the New Orleans Police Department, a function that became structurally significant following the 2012 federal consent decree on police reform. The Ethics Review Board adjudicates ethics complaints against city officials and employees.

Departments interact with the public primarily through the New Orleans 311 Services system, which routes non-emergency service requests to the appropriate agency. The Civil Service Commission governs hiring, classification, and disciplinary procedures for classified city employees — a function that applies across virtually every executive department and insulates much of the workforce from direct political appointment.

Common scenarios

The following scenarios illustrate how residents and businesses typically encounter specific departments:

  1. Property improvement or construction — Requires engagement with the Department of Safety and Permits, the City Planning Commission, and potentially the Historic District Landmark Commission or the Vieux Carré Commission for properties in regulated historic areas. The Zoning and Land Use framework governs allowable uses before permits are issued.

  2. Property taxes and assessments — The Assessor's Office sets assessed values; the Revenue Collection Bureau handles payment. These are independent offices elected or appointed separately from the executive branch.

  3. Public safety complaints — Routed to the New Orleans Police Department for criminal matters or the New Orleans Fire Department for fire and life-safety issues. Civilian oversight of NOPD conduct flows through the Independent Police Monitor.

  4. Infrastructure problems (flooding, roads, water) — The Sewerage and Water Board handles water and drainage infrastructure; the Department of Public Works handles streets and right-of-way. For broader flood risk, the Southeast Louisiana Flood Protection Authority manages levee systems, a body created by state law following Hurricane Katrina.

  5. Housing assistance — The Housing Authority of New Orleans administers federally funded housing programs. The Human Services Authority coordinates behavioral health and social services. These two bodies operate under separate statutory frameworks and serve overlapping but distinct populations.

  6. Business licensing and economic development — The Office of Economic Development manages incentive programs and business attraction. Licensing and revenue functions fall under the Revenue Collection Bureau.

Decision boundaries

Understanding which body has authority — and which does not — is the most common point of confusion in navigating New Orleans city government.

Executive departments vs. independent authorities: The Mayor appoints department directors and can remove them, giving the executive branch direct operational control over departments such as Public Works, the Health Department, and Safety and Permits. Independent authorities such as the Sewerage and Water Board and Regional Transit Authority have their own governing boards, separate revenue streams, and insulated hiring structures. The Mayor typically holds seats on these boards but does not exercise unilateral control.

City functions vs. state-chartered functions: The Orleans Parish School Board governs public education under a state-granted charter, not the city's home rule charter. The Port of New Orleans operates under a state-created board. These bodies receive no direct appropriation from the City Council budget and answer to different oversight chains.

City of New Orleans vs. Orleans Parish courts: Courts in Orleans Parish — including the Civil District Court, Criminal District Court, Juvenile Court, and Traffic Court — are part of Louisiana's unified state court system. They are funded partly by local fees and assessments, but their judges are elected under state law and their jurisdiction is defined by the Louisiana Constitution and state statutes, not by city ordinance.

What this directory does not cover: Services provided by Louisiana state agencies, federally administered programs operating in Orleans Parish, and regional entities whose governing boards include representatives from outside Orleans Parish boundaries fall outside the scope of this city-level directory.
