FEMA Rules When Installing ICC Rated Engineered Flood Vents

Installing ICC Rated Engineered Flood Vents

When, installing ICC Rated Engineered Flood Vents there are a few rules. These FEMA guidelines will help ensure the flood vents will serve their purpose and help protect your home in the event of a flood. Also, installing ICC rated engineered flood vents can help reduce your flood insurance costs.

  • The bottom of the flood vent opening cannot be higher than 12 inches from 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 is required for all engineered flood vents without an ICC-ES certification.
