The proposed bill aims to limit municipal regulations on residential developments consisting of four or fewer units in Minnesota. It introduces a new section, [462.3656] AESTHETIC MANDATES PROHIBITED, which prohibits municipalities from imposing requirements related to construction materials or methods, including aspects such as architectural elements, building egress, durability, energy efficiency, or light access, unless mandated by the State Building Code or other applicable state or federal laws. Additionally, the bill outlines specific exemptions, allowing properties in historic districts to be excluded from these regulations and permitting municipalities to require an egress point on the street-facing side of the structure. It also states that no municipality can enact an interim ordinance related to these policy changes, ensuring immediate compliance with the new regulations upon enactment. The effective date for this section is set for the day following final enactment.
