Behin Ha Adds Three Townhouse ADUs Behind Historic Jersey City House

architecture-design · 2026-08-26

In December 2025, Behin Ha, under the leadership of Behrang Behin and Ann Ha, finalized the construction of three townhouses at 11 Beacon Avenue in Jersey City, situated on a 5,000-square-foot parcel. This location was previously occupied by a single-family residence that had suffered fire damage. Initially, Behin's brother Babak envisioned a 4-story building with 9 rental units; however, zoning laws mandated historic office approval for buildings older than 150 years. The brothers opted to restore the original house, converting it back into a single-family dwelling, and subsequently developed three two-bedroom townhouses, referred to as 'hyper-ADUs.' Each townhouse spans approximately 2,000 square feet, surpassing Jersey City's 650-square-foot ADU limit. The project involved Alan Feld Architect, Eastern Shore Builders, LQ Benatg, Ryan Soames Engineering, and Bazz Consulting.
