Montgomery County - Prohibited Restrictions on Use - Accessory Dwelling Units MC 2-25

HB 1234 prohibits Montgomery County property restrictions that block accessory dwelling units (ADUs) - secondary homes on the same lot as a primary residence. It declares any existing deed covenant, HOA rule, or similar restriction banning ADUs void and unenforceable, applying retroactively to all past restrictions. The law directly affects Montgomery County homeowners and HOAs with such prohibitions, allowing them to build ADUs under existing state law without legal barriers. The bill takes effect October 1, 2025, and does not create new ADU requirements or funding.
