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 laws. The bill also outlines specific exemptions, allowing properties in historic districts to be exempt from these regulations and permitting municipalities to require an egress point on the street-facing side of the structure. Additionally, the bill includes a provision that prevents municipalities from enacting interim ordinances related to the policy changes introduced in this section, as stated in Subd. 3. Interim ordinance. The effective date of this legislation is set for the day following its final enactment. Overall, the bill seeks to streamline residential development processes by reducing regulatory burdens on smaller housing projects.
