Codes - As introduced, extends the period in which the fire marshal is required to provide a decision on an appeal regarding building or fire codes involving a county building located in a city when there is a conflict between city and county from 10 working days to 15 calendar days. - Amends TCA Title 68, Chapter 102 and Title 68, Chapter 120.

HB 718 extends the deadline for Tennessee's fire marshal to decide building or fire code appeals involving county buildings in cities with conflicting city-county regulations. The bill changes the timeframe from 10 working days to 15 calendar days after receiving a written appeal. This directly affects county governments and building owners facing code disputes between local jurisdictions. The key change simplifies the timeline by switching from "working days" to "calendar days," reducing potential delays caused by weekends or holidays. The amendment applies to specific sections of Tennessee's building code (TCA Title 68, Chapters 102 and 120).
