Gretna, Louisiana: City Government and Services
Gretna is an incorporated city within Jefferson Parish, situated on the west bank of the Mississippi River directly across from New Orleans. This page covers Gretna's municipal government structure, the services it delivers to residents, how its authority relates to Jefferson Parish government, and the practical boundaries separating city functions from parish and state functions. Understanding these layers matters for property owners, business applicants, and residents navigating permits, utilities, public safety, and elected representation in the West Bank community.
Definition and scope
Gretna is a Lawrason Act municipality under Louisiana state law, meaning its foundational governance framework is set by Louisiana Revised Statutes Title 33, which governs the structure, powers, and limitations of municipalities that have not adopted a home rule charter. The city operates under a mayor-council form, with an elected mayor serving as chief executive and an elected board of aldermen functioning as the legislative body.
Gretna's incorporated city limits cover approximately 2.6 square miles, making it one of the more compact municipalities in the New Orleans metro region. The population recorded in the 2020 U.S. Census was 17,693 (U.S. Census Bureau, 2020 Decennial Census). The city is the parish seat of Jefferson Parish, which gives it additional administrative significance beyond its modest land area.
Scope and coverage limitations: This page addresses Gretna's city-level government only. Jefferson Parish government — which provides a parallel layer of services to Gretna residents — is covered separately on the Jefferson Parish Government page. State-level regulations issued by Louisiana, federal programs administered through agencies such as HUD or FEMA, and the governance of neighboring municipalities such as Kenner and Metairie fall outside the scope of this page. The page does not cover Orleans Parish or the consolidated city-parish government of New Orleans, which is addressed at New Orleans Consolidated City-Parish.
How it works
Gretna's government operates across two primary branches at the local level:
-
Mayor — The mayor is elected citywide to a four-year term, manages day-to-day city operations, appoints department heads, prepares the annual municipal budget, and represents Gretna in intergovernmental negotiations. The mayor also serves a ceremonial role as the public face of the city.
-
Board of Aldermen — Aldermen are elected by district and serve four-year terms. The board adopts ordinances, approves the city budget, sets tax millage within limits established by Louisiana law, and provides legislative oversight of executive functions.
Key municipal departments and service areas include:
- Gretna Police Department — Primary law enforcement within city limits, separate from the Jefferson Parish Sheriff's Office, which handles unincorporated Jefferson Parish and parish-wide functions.
- Gretna Fire Department — Provides fire suppression and emergency response within city limits.
- Public Works — Manages street maintenance, drainage infrastructure, and city-owned facilities.
- Planning and Zoning — Administers land use regulations, issues zoning decisions, and processes variance applications under the city's zoning ordinance.
- Municipal Court — Handles ordinance violations and minor civil matters arising under city law.
An important structural distinction separates Gretna from unincorporated Jefferson Parish: residents within Gretna's city limits pay city property taxes in addition to parish taxes and receive services from both the municipal government and the parish. Residents in unincorporated Jefferson Parish areas on the West Bank — such as parts of Harvey or Marrero — receive services exclusively from Jefferson Parish government without a city layer.
Common scenarios
Residents and property owners encounter Gretna's city government in four primary situations:
Building permits and zoning. Any construction, renovation, or change of use on property within city limits requires a permit from Gretna's Planning and Zoning office, not Jefferson Parish's permit office. Confusion between these two bodies is the most common administrative error made by contractors working across the West Bank.
Traffic and ordinance enforcement. Citations issued within city limits by Gretna Police Department are adjudicated in Gretna Municipal Court. Citations issued by the Jefferson Parish Sheriff's Office in unincorporated areas go through the Jefferson Parish court system. The distinction affects fine payment, hearing procedures, and appeal rights.
Business licensing. Operating a business within Gretna requires both a city occupational license and compliance with Jefferson Parish regulations where applicable. Dual licensing requirements are standard for any business located within an incorporated municipality in Louisiana.
Property tax billing. Gretna property owners receive tax bills reflecting city millage set by the Board of Aldermen and parish millage set by the Jefferson Parish Council. Louisiana's property tax framework, administered through the Louisiana Tax Commission (Louisiana Tax Commission), governs assessment methodology for both layers.

Louisiana's Lawrason Act sets the outer limits of what Gretna can legislate. The city cannot enact ordinances that conflict with state law or exceed the powers granted under Title 33. On matters where the state has preempted local action — firearms regulation being one example established under Louisiana law — Gretna's ordinance-making authority does not apply.
Regional governance bodies that affect Gretna residents but sit outside city or parish authority include the New Orleans Regional Transit Authority, which operates bus routes serving the West Bank, and the Southeast Louisiana Flood Protection Authority, which manages levee infrastructure protecting Jefferson Parish communities. Neither body is accountable to Gretna's mayor or aldermen.
