Substitute House Bill No. 5502 seeks to enhance housing development on specific lots by modifying existing zoning regulations. The bill changes the effective date for new zoning regulations from July 1, 2026 to January 1, 2027. It requires that zoning regulations permit the development of transit community middle housing or mixed-use developments on lots zoned for commercial or mixed-use, industrial use (within 1,000 feet of a transit station or highway), or previously zoned for residential use. Additionally, the bill introduces a summary review process for these developments, allowing for expedited approval without public hearings, and provides municipalities with housing unit-equivalent points for each unit of middle housing that receives a certificate of occupancy. The bill also amends the criteria for awarding housing unit-equivalent points under Section 8-30g, ensuring that points are granted for units in transit community middle housing developments. It prohibits municipalities that adopt zoning regulations for these developments from repealing or significantly modifying them during a moratorium period if they have received housing unit-equivalent points. Overall, the bill is anticipated to have minimal fiscal impacts on municipalities, potentially leading to savings and revenue losses due to reduced public hearings and permit fees associated with the new summary review process.
