Codes - As enacted, clarifies that, as of July 1, 2025, the roof solar reflectance and thermal emittance requirements of the International Energy Conservation Code for low-sloped roofs do not apply to the 2021 International Code Council adoption; authorizes the state fire marshal to promulgate rules to that effect. - Amends TCA Title 68, Chapter 120.

HB 801 removes a specific energy efficiency requirement for low-sloped roofs in Tennessee. It amends state law to clarify that the International Energy Conservation Code's roof solar reflectance and thermal emittance rules no longer apply to such roofs starting July 1, 2025. This change directly affects builders, developers, and homeowners constructing or renovating low-sloped roofs across Tennessee. The bill achieves this by adding a new provision to Tennessee Code Title 68, Chapter 120, eliminating the requirement without creating new rules. The law became effective April 3, 2025, with the policy change taking effect on July 1, 2025.
