Town Information For Mountainside NJ 07092

Looking for some peace and quiet but still want the city nearby? Mountainside is the place for you. The borough of 4.0497 square miles has a small population of 6,808 and split from its neighboring town, Westfield, in 1895. There is a 50-year-old zoning ordinance in order to preserve the town’s beautiful rural feel and landscape. This means most retail services, besides restaurants and a movie theater, are banned along the highway. This also means there are no condominiums, townhouses, or apartment buildings.

Mountainside consists of mostly single-family homes including bi-levels, split levels, capes, and colonials. Most of the homes in this area were built before 1970 and are typically sold from the $200,000 range up to over a million dollars. The further you go up the mountain, the higher the prices of the homes, but the better the view of the New York City skyline. Despite the pricing of the homes, the taxes are actually quite low, being the lowest of the 21 municipalities of Union township.

Mountainside offers public schooling for children in kindergarten through second grade at Beechwood School and third through eighth graders can attend Deerfield School.
