Flanked by members of the New Orleans City Council and City Planning Commission, Mayor Mitch Landrieu signed the city’s new comprehensive zoning ordinance — a massive overhaul of the law that has governed zoning in New Orleans for more than 40 years — into law Friday.

“This new CZO will ensure greater consistency, transparency and civic engagement in the planning and development of New Orleans,” Landrieu said in a statement. “This CZO incorporated years of careful study, review, public comments and input and hard work by countless folks committed to the future of New Orleans — and we are stronger for it.”

The new CZO is intended to give legal force to the guidelines and principles set forth in the city’s master plan for long-term development. It governs development on all property in New Orleans and includes lists of permitted land uses for each zoning classification, as well as height limits, building sizes, setback requirements, urban design standards, operational rules and other regulations.

The City Council unanimously passed the ordinance in May after a discussion that lasted seven hours.

The new law likely will be amended many times over the coming months and years. The city’s last zoning law, passed in the 1970s, was amended hundreds of times over the decades.
