Raised Bill No. 1027 Summary

• Defines "accessory dwelling unit" (ADU) as an independent residential dwelling unit located within or attached to a single-family dwelling that includes sleeping, food preparation, and sanitation facilities and complies with building code and health/safety regulations.

• Requires municipalities to permit one ADU as of right per lot containing a single-family dwelling without imposing additional lot size, lot coverage, frontage, or space restrictions beyond those for single-family dwellings.

• Prohibits municipalities from requiring familial relationships between occupants, limiting bedrooms to one, or restricting the maximum square footage of ADUs to less than 750 square feet.

• Allows municipalities to require an interior door between principal and accessory dwelling units (but not require it to remain locked), require adequate parking and water/sewer provisions, and establish aesthetic standards.

• Reduces zoning commission voting requirement for protested zoning regulation or boundary changes from two-thirds to simple majority vote and increases affordable housing point thresholds for municipalities seeking moratoriums.
