This bill introduces new regulations regarding zoning ordinances for single-family residential uses, specifically addressing lot size requirements in relation to sewer infrastructure. It prohibits municipalities from mandating larger lot sizes than necessary for community health and safety, particularly for lots not serviced by municipal or community sewer systems. The bill stipulates that for such lots, no ordinance shall require sizes larger than those mandated by the Department of Environmental Services for individual sewage disposal systems, unless the municipality can provide empirical evidence demonstrating that health or safety would be significantly compromised. For lots serviced by municipal sewer systems, the maximum lot size is set at 22,000 square feet, contingent upon adequate sewage system capacity.

Additionally, the bill clarifies that the new requirements will not affect the development potential of lots created before July 1, 2025, and it does not override existing municipal zoning regulations unrelated to minimum lot sizes. The act is set to take effect on July 1, 2025. The fiscal impact of the bill is indeterminable, as municipalities may incur costs related to amending zoning ordinances and gathering necessary empirical evidence to justify any larger lot size requirements.
