Searches building permits across six US cities for real-estate due diligence: NYC (DOB), San Francisco, Chicago, Los Angeles, Seattle, and Austin. Each city's open-data Socrata feed is normalized to a common permit shape (permit_id, type, status, description, address, zip, filed/issued/expiration dates, applicant, work category), with filters for address substring, permit status, permit type, and recency window. A real-estate, construction, and code-compliance primitive. Use it as a construction permit search, DOB permit fetch, city open-data permits API, or property permit history lookup.
