In this corridor STR eligibility swings property value more than any other single factor. A buyer who assumes 'the neighbor has an Airbnb so I can too' can eat a five-figure loss. Eligibility is set parcel-by-parcel: town limits, zoning districts, license caps, and waitlists.
Counties publish their actual STR license registries as open GIS layers (Boulder does), and cap/waitlist rules live in county code pages. No aggregator normalizes them per parcel. We join licenses to parcels and encode each jurisdiction's rulebook.
