allowing high-density residential development on land zoned for commercial use.

SB 90 allows municipalities to permit high-density residential housing (defined as at least 20 units per acre) on land currently zoned for commercial use like retail or offices. It directly affects local governments, which must permit such development if adequate infrastructure (roads, water, sewage) is available or provided. The bill amends zoning rules to remove barriers for mixed-use projects combining residential and commercial space, requiring only that infrastructure supports the new housing. This policy change aims to increase housing options in areas currently limited to business uses, without mandating new construction. The law takes effect 60 days after passage.
