Where Do I Put Flood Vents

Where do I put flood vents when installing them on your home or garage? Whether installing engineered openings or non-engineered openings the FEMA requirements are the same.

• The bottom of the flood vent opening cannot be higher than 12 inches above grade.
• A minimum of two flood vents for each enclosed area (crawlspace, garage, or rooms within a garage), and each flood vent must be on at least two different walls.
• A minimum of one engineered square inch of opening for each square foot of enclosed area for an engineered flood vent. Or a minimum of one square inch of net open area for each square foot of enclosed area for non-engineered openings.
• An Engineered Certificate of Flood Openings or ICC-ES report is required for engineered flood vents.
