Lot Coverage Regulations

The Comprehensive Zoning Ordinance (CZO) provides limitations on how much yard area can be covered with "impermeable" materials (such as concrete or asphalt) as well as regulations on how much total area of a lot is required to remain "permeable," meaning that it does not have paving or buildings on those areas. The table below provides a snapshot of these regulations, full district-by-district requirements can be found at czo.nola.gov.
