Statewide question pages and parcel lookups: 24 state-level answers, 68 official viewer links

Two additions. First: state-level question pages — 12 for Washington, 12 for Colorado — answering the questions people actually ask at the state level (How many ADUs can I build? Can cities require owner-occupancy? What does a permit cost?), each cited to the statute or explicitly marked 'varies by city' with the divergent cities named. Every city-specific number in every answer was traced back to the verified city record before publication, and a sampled adversarial pass re-checked four load-bearing claims against primary sources. Second: every city page now carries a 'Check your parcel' block linking the official county parcel viewer, assessor search, and city zoning map — official domains only, each link verified live. The rules are citywide; what you can build depends on your lot, and now the path from our pages to your parcel is one click.
