NSPIRE (National Standards for the Physical Inspection of Real Estate) is HUD's (U.S. Department of Housing and Urban Development) new, standardized inspection system for HUD-assisted housing, replacing older standards like UPCS and HQS to focus more on resident health and safety by evaluating properties in three zones: Unit, Inside (common areas), and Outside. It aims to streamline inspections, clarify standards for functional adequacy, and promote better maintenance by prioritizing serious health/safety hazards over minor cosmetic issues, with implementation rolling out across programs.
