Administrative Practice Change and Retroactivity in Building Safety Requirements

A party sought judicial review regarding a change in administrative practice concerning building safety requirements, specifically related to window fall protection, after an initial authorization was issued, arguing that the new standard, which was stricter and aligned more closely with existing regulations, could not be applied retroactively to the existing construction project. The court held that the administrative authority was entitled to change its practice to better conform to the existing legal prescriptions, even concerning an already authorized project, emphasizing that adherence to safety standards is paramount and that the principle of good faith does not prevent the administration from enforcing stricter but legally compliant safety measures over time.
