Work out which permits a project actually needs and the order to get them — building/renovation, business licensing, events, signage, home businesses — so you don't build first and discover the permit later. Use when someone says 'do I need a permit for this', 'what permits for my renovation/business/event', 'help me apply for a permit', or 'the council flagged my project'. Produces a permit checklist with the likely permits, their sequence and dependencies, and the official offices to confirm each. Not legal/code advice — it orients and routes to the authority.
