An Act amending the act of June 13, 2008 (P.L.182, No.27), known as the Clean Indoor Air Act, further providing for title of act, for definitions, for prohibition, for signage, for enforcement, for preemption of local ordinances and for repeal; and making editorial changes.

This bill amends Pennsylvania's Clean Indoor Air Act (2008) to update definitions, expand smoking prohibitions, clarify signage requirements, strengthen enforcement mechanisms, and clarify that state law preempts stricter local smoking ordinances. It directly affects businesses operating in public spaces (like restaurants, bars, and workplaces) and local governments that previously enacted more restrictive smoking bans. The key change is reinforcing state-level rules over local ones, while making editorial updates to the existing law's structure. This focuses on maintaining consistent indoor air quality standards across the state.
