Plan cabinets for humidity and flood risk
EPA moisture guidance, one manufacturer's humidity advice, and FEMA's rating of cabinet materials below the base flood elevation.
What is not established
- Whether a property or room is below the base flood elevation is not established.
- No cabinet material is recommended for a specific home.
- Manufacturer humidity guidance and warranty terms vary by line.
Indoor moisture
EPA's brief guide to mold and moisture advises keeping indoor humidity below 60 percent, ideally between 30 and 50 percent, using exhaust when cooking or running the dishwasher, and fixing leaks and drying wet materials within 24 to 48 hours. The guide does not mention cabinets.
Showplace Cabinetry's humidity page recommends a stated relative-humidity range year-round, conditioning seasonal homes while unoccupied, and engineered door styles for painted cabinets in coastal or humid areas, and says joint lines from wood movement are not warranty defects. That is one manufacturer's guidance for its own products; ask your seller for the guidance and warranty terms that apply to the quoted line.
Below the base flood elevation
FEMA Technical Bulletin 2 (January 2025) treats cabinets as finish materials. It rates built-in metal cabinets acceptable below the base flood elevation and built-in wood or particleboard cabinets unacceptable. This applies only below the base flood elevation in a special flood hazard area, and plywood boxes are not rated separately from particleboard.
