Building rules change: cycles move, new ordinances pass, deadlines shift. We track every change we find against official sources, dated, and keep the history public. The same feed powers deadline tracking for every building on Certmill.
Cooling tower certifications moved to twice yearly (January and July) under 2025 state legislation (S08472-A). Penalties for violations now reach $7,000 for repeat offenses.
Added facade inspection ordinances for Boston (sec 9-9.12, $300/day for non-compliance), Philadelphia, Jersey City, Cincinnati, Cleveland, Columbus, Detroit, Milwaukee, Pittsburgh, and St. Louis.
Added Florida coverage: elevator certifications (ch. 399), Miami-Dade BE305 benchmarking, Miami-Dade 40-year recertification, Tampa backflow testing, and Broward County 40-year recertification.
Penalty data added to requirement rows: what missing a deadline costs, with the official source. Future-dated rules now show a 'takes effect' countdown before they become enforceable.
