Retaining walls are not on the list of work a New York local program may exempt from a permit (19 NYCRR 1203.3(a)(1)). A retaining wall not laterally supported at the top that holds back more than 48 inches of unbalanced fill, or one over 24 inches tall that resists lateral loads in addition to soil, must be engineered with a 1.5 safety factor against sliding and overturning (RCNYS R404.4).
