Evanston requires a building permit for retaining walls over 4 feet in height (measured from the bottom of the footing to the top of the wall).

Evanston limits fence heights to 4 feet in front yards and 6 feet in side and rear yards in residential districts. Corner lots have additional visibility triangle restrictions. Higher fences may be approved through a variation from the Zoning Board of Appeals.
