Description

This exceptional 1.91-acre property in Lafayette, CA, presents a unique mixed-use development opportunity. Located in the desirable West End District, the site boasts a prime location near restaurants, retail, the Lafayette Reservoir, and Oakwood Athletic Club. Currently zoned C (General Commercial), the property offers significant upside potential with a new 60 units per acre density allowance, allowing for approximately 114 to 155 units (with a potential 35% state density bonus). The existing approximately 48,000 square feet of office space is approximately 60% leased, generating substantial income while entitlements are processed. This represents the largest contiguous parcel of unentitled land in this ultra-premium submarket, offering a covered land play with strong underlying fundamentals. Easy access to Highway 24 and BART provides convenient connectivity. The fee-simple ownership and APN 241-010-047/048 further enhance this compelling investment opportunity. The property includes 155 units across multiple buildings, classified as Class B. This is a rare chance to capitalize on the revitalization of Lafayette's West End and the high demand for housing in this affluent community. The property consists of a multifamily component, office space, and land, offering flexibility for a variety of development scenarios.
