Monmouth County, NJ Building Setbacks & Zoning: Structure Height Limits (2026)

Building height in Monmouth County is controlled by each municipality's zoning ordinance under NJ MLUL. Standard residential height limits across Monmouth: 30 to 35 feet measured from average finished grade to highest roof point, and 2 to 2.5 stories. Estate zones (Rumson, Colts Neck, Holmdel, Deal) often permit 35 feet with larger massing allowances. Downtown commercial zones in Red Bank (up to 55 feet with redevelopment plan bonus), Long Branch (Pier Village mixed-use up to 80+ feet per redevelopment plan), and Asbury Park (Waterfront Redevelopment Area with specific height districts up to 95 feet for hotels) allow higher buildings. Freehold Borough, Matawan, and Keyport have modest downtown height limits (45 to 55 feet). Height is measured from average finished grade in most Monmouth codes. Chimneys, antennas, HVAC screens, elevator overrun, and parapets are typically exempt up to a limited bonus (usually 4 to 10 feet). Historic districts (Ocean Grove, Spring Lake, Allenhurst) enforce strict compatibility — additions cannot exceed the height of the original structure without HPC approval. Coastal flood zones (VE/AE) often require raised first-floor elevation, which can pressure against height limits — some Monmouth shore towns exempt NFIP-required elevation from height calculation. Height variances require C-variance hearing.
