Bill > HB2991

This bill establishes rules for how certain counties, specifically those with a charter form of government and over 700,000 residents, can regulate mixed-use residential (developments where at least 65% of the square footage is residential) and multifamily residential (developments with three or more dwelling units) projects, as well as the conversion of existing commercial buildings to these residential uses. It clarifies that municipalities within these counties cannot prevent such developments in zoning areas that already allow office, commercial, retail, warehouse, or mixed-use development, and they cannot require zoning changes or special approvals for these residential projects unless the area is zoned for heavy industrial use or is near an airport or military base. The bill also sets limits on municipal regulations for these developments, preventing them from imposing stricter density limits than 36 units per acre, height limits than 45 feet, or setback requirements than 25 feet, and restricts parking requirements to no more than one space per unit. For conversions of existing commercial buildings, the bill prohibits municipalities from requiring traffic studies, traffic improvement fees, additional parking beyond what already exists, utility upgrades beyond minimum capacity, or design requirements stricter than the International Building Code. Furthermore, it allows housing organizations or affected individuals to sue municipalities for violations of these provisions and recover legal costs if they win.
