Description

Berkadia, in conjunction with Cushman & Wakefield, is pleased to exclusively present 1100–1120 Mar West (“Mar West” or the “Site”), a rare generational development opportunity in Tiburon, an ultra-affluent Marin County waterfront community that has delivered no new multifamily in over 50 years and no new condominiums in 20 years. Distinctly identified as one of Tiburon’s high-potential Housing Sites, Mar West offers a streamlined path to approvals with baseline densities of 30-35 units per acre and additional potential under State Density Bonus Law, accommodating market-rate, affordable, or senior housing developments. Ideally situated along Tiburon Boulevard at the gateway to the town’s high-end bayfront retail district, the Site provides immediate and walkable access to premier dining, shopping, transit, and abundant outdoor recreation, delivering the quintessential Marin lifestyle. Set within one of the most exclusive and high-barrier-to-entry markets in the country featuring a median home sale price of $3.2MM and average household income of ±$405,000, Mar West represents an extraordinary development opportunity situated on irreplaceable real estate and poised to capitalize on the area’s outstanding housing fundamentals.
