Local Government, General - As enacted, authorizes Putnam County and incorporated cities within the county to regulate sober living homes for recovery from alcohol, drug, and substance abuse to the extent such regulation complies with the Fair Housing Act and the Americans with Disabilities Act. - Amends TCA Title 7, Chapter 51, Part 26.

HB 2196 authorizes Putnam County and its incorporated cities (with specific population ranges) to regulate sober living homes for substance abuse recovery, provided rules comply with the Fair Housing Act and Americans with Disabilities Act. The bill amends Tennessee law to define eligible local governments based on 2020 census population thresholds (county: 366,200-366,300; cities: 79,800-79,900). It directly affects sober living homes operating in Putnam County and its cities by establishing their regulatory framework. The key provision ensures local regulations cannot violate federal civil rights protections for residents seeking recovery housing.
