Key takeaways

This directory records 236 authorities that issued permits in Mississippi and 8,405 residential units reported for 2025. Our analysis of the Census survey shows reporting scale, not whether an authority has an open permit database or whether a particular project is active. Those questions need the authority’s own current record.

  • Use the authority name to locate the primary record.
  • Check local data availability separately.
  • Verify a project before outreach or a bid decision.

Common question

Does inclusion mean Projects Ahead has a usable project signal there?

No. Inclusion means the Census survey identifies an authority that issues permits. A usable project signal requires separate testing of source access, fields and the ability to reconstruct a project timeline.
