Key takeaways
- Failed visits require mutually clear cause categories.
- Scheduling and arrival checkpoints produce different evidence.
- Rates need workload and property context.

A failed visit can reflect notice, resident availability, vendor timing, access equipment, hazards, or an unclear scope. Combining these events into one percentage produces a simple number but weak operational guidance.
Research question
Which minimum fields allow a portfolio team to distinguish preventable access failures from other unsuccessful visits and select an appropriate process correction?
Methodology
The framework reviews work-order and communication records at two checkpoints: scheduling confirmation and site arrival. Events are classified into six cause families: authority or notice, resident coordination, vendor timing, key or device, safety condition, and scope mismatch. Reviewers preserve an unknown category, perform a second review of ambiguous cases, and calculate counts with total scheduled visits as the denominator.
Evidence and interpretation
Relevant public context includes HUD healthy-homes material, EPA indoor-environment guidance, OSHA standards, FEMA risk-management resources, CPSC safety guidance, and NIST measurement resources. These sources inform safety and measurement context but do not validate portfolio-specific failure rates.
Limitations
Administrative records may reflect inconsistent coding and missing resident or vendor context. Small portfolios can show unstable percentages. The method does not determine lawful entry, allocate fault, or replace emergency procedures. Local law, leases, and management agreements must control access decisions.
Source treatment and application
Sources were selected for public authority and used only within their scope. The proposed categories are an editorial operational synthesis. Teams should pilot the access confirmation, double-code a sample, report unknowns, and revise definitions before comparing teams or vendors.
