Mobile Homes and Manufactured Buildings - As enacted, requires this state's definition of manufactured home to automatically update with the definition of manufactured home under title 42 of the United States Code, which currently excludes a self-propelled recreational vehicle. - Amends TCA Title 47; Title 55 and Title 68.

SB 119 updates Tennessee's legal definition of "manufactured home" to match the federal definition in 42 U.S.C. § 5402(6), which currently excludes self-propelled recreational vehicles (RVs). This change affects how the state classifies and regulates manufactured homes, ensuring alignment with federal standards and removing RVs from this category. The bill amends three sections of Tennessee law (Titles 47, 55, and 68) to adopt the federal definition without modification. The law takes effect on July 1, 2025, requiring state agencies and local governments to use this updated definition for regulatory purposes.
