Because this proposal had NOT yet been passed by ordinance as of the last verification date below, the 2018-edition code set adopted by Resolution 2023-43 (described above) remains the currently governing, legally adopted baseline; this dataset reflects that currently-adopted baseline rather than the not-yet-final proposal. The exact new edition years were not stated in the publicly available summary and could not be independently confirmed from an adopted ordinance text at the time of this review — see confidence notes.; Manufactured homes are addressed via a dedicated flat permit fee (Manufactured Home Installation) on the City's Processing Review Fee Schedule rather than the standard valuation-based building permit fee.
