You would think if a property in Orleans Parish has the same zoning designation as a property in Jefferson Parish, that the permitted use would be the same. Logical, but not true. In Orleans Parish, the C-1, Commercial, zoning designation allows residential, single-family development, but in Jefferson Parish, new single family development is not allowed. You have to read the Jefferson Parish Zoning Code carefully, since the language initially states residential is allowed, but that means existing residential. If you are developing residential on vacant land in Jefferson Parish, you cannot do so in C-1 zoning. Here is how the zoning code actually reads in each parish. Notice how in Orleans Parish you have to follow the lineage since one zoning designation allows a different zoning designation.
