Exceptional development opportunity in the heart of Winnetka. RTI plans call for a front duplex with each residence offering 3 bedrooms and 2 bathrooms (each projected to rent at approximately $3,950/ month), developed through SB9, along with two newly constructed 2BD/2BA ADUs (each projected to rent at approximately $2,950/month) at the rear of the property. The proposed configuration creates a highly desirable four-unit compound, ideal for investors, builders, or end users seeking long-term income, multi-generational living, or resale flexibility. With its efficient layout and strong unit mix, the project is well-positioned to maximize rental yield and future value. Ideally located near Westfield Topanga, parks, public transit, and major freeways, this property combines prime location with compelling development upside in one of the Valley's most accessible neighborhoods.
