On this page Permit and Licence Databases as Business Intelligence
Building permits, business licences and professional licences are public records that signal commercial activity before it is visible to competitors. A new building permit means construction spending; a new business licence means a new customer; a professional licence renewal means an active practitioner:

Processing Permit and Licence Research Data
When compiling prospect data from municipal building permit databases (HTML, CSV), state Secretary of State business filings (HTML, CSV), professional licensing board databases (HTML, PDF), third-party permit data services (CSV), county assessor records, FOIA request responses (CSV, PDF), chamber of commerce directories and cross-referenced LinkedIn profiles, upload the files to Email Extractor to extract and deduplicate email addresses across all research sources. Business owners and professionals appear across permit databases, business filings, professional licences and industry directories under personal names, business names and DBA names, so deduplication prevents contacting the same person through overlapping outreach campaigns.
