Architectural and Historical Ratings

Each building in the Vieux Carré is assigned a rating of architectural and historical significance. Commission policies consider the architectural and historical importance of the building. A treatment allowed on a 20th century building may not necessarily be permitted on a building of greater age.

Rating	Description
Purple	Of National Architectural or Historical Importance.
Blue	Of Major Architectural or Historical Importance.
Green	Of Local Architectural or Historical Importance.
Pink	Of Local or Major Architectural or Historical Importance That Has Been Detrimentally Altered (but, if properly restored, could be upgraded to Blue or Green).
Yellow	Contributes to the Character of the District.
Orange	Unrated 20th Century Construction
Brown	Objectionable or of no Architectural or Historical Importance.

The existing ratings for all buildings in the Vieux Carré, which were initially assigned in the early 1960's, were reviewed by the Commissions's staff and a special committee of the New Orleans Chapter of the American Institute of Architects in 1987-89 with final Commission review and adoption in 1989.
