HUD Code wind zones and site conditions
HUD's public manufactured-housing materials describe three wind-zone design levels: Zone I is associated with 70-90 mph wind speeds, Zone II with up to 100 mph, and Zone III with up to 110 mph. The same material gives Zone I horizontal wind loads of at least 15 pounds per square foot and net uplift loads of at least 9 pounds per square foot. These are design criteria, not a forecast of a particular storm.
The comparison is between the home's data-plate design zone and the site's required zone. HUD says a home should never be placed in a more restrictive wind, thermal, or roof-load zone than the one for which it was built. The wind figure does not measure a park's actual exposure, and a label alone does not prove installed anchoring or foundation performance.
For a park register, a VA can capture each section's certification label, data-plate zone, model year, installation instructions, location, installer record, anchor inspection, and local approval. Compare the recorded site zone with the home's design zone before a move or replacement. Escalate a mismatch or missing label; do not make an engineering or safety determination from a database entry.
