"New Jersey Housing Opportunity Act"; enhances opportunities for housing production.

This bill requires New Jersey municipalities to revise their zoning regulations within four months to allow denser housing options in single-family residential areas. Specifically, municipalities must adopt one of three options: limit single-family lot sizes to 0.25 acres or less, permit two-unit dwellings on single-family lots, or allow accessory dwelling units (ADUs) - like separate living spaces with full kitchens and bathrooms on the same lot. It directly affects all municipalities with residential zoning, exempting historic districts and lots with pre-existing covenants restricting development. The law takes effect immediately upon enactment, mandating compliance to increase housing production opportunities.
