Quick Overview
The 2023 American Housing Survey housing-quality infographic covered 133.2 million occupied housing units. It reported 11.8 million units with water leakage from outside and 3.9 million with mold in the prior 12 months.
What the statistic measures
The AHS asks about physical conditions and recent household experience. Other reported counts include 15.7 million units with signs of mice or rats and 11.2 million with water leakage from inside. These are national estimates, not inspection findings for a given address.
Rental operations application
Use the inspection evidence pack to capture location, date, image, and next action. Pair it with inspection evidence quality research when reviewing whether a repair record supports the conclusion.
Common Mistakes
Do not turn a survey count into a claim that a market has a defect rate equal to the national estimate. Do not close a work order because a resident report lacks a photograph. Record what is known and what still needs inspection.
Common Questions Answered
Does the AHS count prove a defect?
It reports survey responses about housing conditions. A property decision still needs a qualified inspection or other appropriate evidence.
How often should a portfolio review the categories?
Set the cadence from risk, lease, and local requirements. The national survey does not prescribe a maintenance schedule.
Source and limits
The 2023 AHS housing quality infographic is the source for the counts. Sampling, definitions, and respondent reporting affect comparability.

Use the categories as a checklist for evidence quality, not as a substitute for an inspection.
