relative to accessory dwelling units.

HB 1136 simplifies rules for accessory dwelling units (ADUs), like backyard cottages or in-law suites, making them easier to build on single-family properties. It allows municipalities to permit ADUs automatically (without special permits) or through standard processes, permits multiple ADUs per home, and sets a 750-square-foot minimum size. The bill clarifies that towns without ADU rules must allow one ADU by default (beyond basic building permits), expands access standards to all ADUs, and prohibits ADUs in townhouses, manufactured housing, or rented land. Homeowners, local governments, and potential renters are directly affected by these changes to zoning and construction rules.
