Entryways in single- and two-family residences

For single- and two-family residences with enclosed entryways below flood-resistant construction elevation, up to 10 square feet of such entryway may be excluded from the definition of floor area for each foot of difference between the lowest occupiable floor and curb level. This area may be excluded from the definition of floor area provided it is not greater than the total area of ramps, stairs, lifts and elevators between grade and the first finished floor, plus an initial entry area of no more than 12 square feet.
