Though small, Weehawken is very urban, with a population density that is among the highest in the United States and comparable with that of nearby Jersey City. Weehawken is a residential community of primarily one- and two-family homes (many built during the Edwardian era) and low-rise apartment buildings.
Weehawken has a retail district along Park Avenue (its boundary with Union City) and large office and apartment/townhouse developments along the Hudson River. A few scattered retail shops and light manufacturing facilities blend into their respective neighborhoods. Local zoning laws prohibit the construction of high-rise buildings that would obstruct sight-lines from higher points in town.
