Data sources
Public agency datasets powering Housing BuildDesignHub
Housing BuildDesignHub is built on citable public data — no scraping of commercial listing sites. Each source shows its current use, future role, and adapter wiring status.

Civic context
A federal public-data office, not a partner
A verified Wikimedia Commons photo of the U.S. Census Bureau headquarters is used here as civic data-source context. It does not imply partnership, endorsement, or live integration. Housing BuildDesignHub's Census-derived metrics come from public ACS and BPS releases via the source-adapter pipeline.
