Permit requirement records include Site-specific permit submittal and Site and utility review. Fee records include Plan-set purchase fee, City-owned plan cost, and others. When a source did not publish a value, the page keeps that field as Not listed in source instead of filling a blank.

Use these listings as a starting point for matching a plan to a property. Source links, checked dates, acceptance notes, and provider records are shown so you can verify whether a plan remains accepted locally, what site-specific review remains, and whether local fees, plan licensing, or provider terms apply.
