Construction Monitor is a long-established national provider of building-permit data, selling permit lists, mailing lists and market reports across the US, often customized by region and permit type.
Build Siren overlaps on the core idea — permit data as leads — but is deliberately narrow: Southeast Michigan, per-trade, scored, delivered daily in formats built for immediate outreach, at a local-contractor price.
