Avison Young is pleased to present 670 N. Rosemead Boulevard, an exceptional opportunity to acquire a ±14,448 SF office building on ±1.28 acres in Pasadena, California. The property is well-suited for an office owner-user or investor, with compelling upside as a by-right high-density residential development site allowing up to 48 units per acre. Constructed in 1975, the two-story, elevator served office building features dedicated surface parking at a 3.00/1,000 SF ratio (43 spaces) and low site coverage. The existing improvements offer immediate occupancy for an owner-user or investment potential, while the underlying land value and favorable zoning create a clear path to by-right residential redevelopment. The property’s by-right density of up to 48 units per acre supports a wide range of high-density residential strategies, including for-sale townhomes, market-rate rental apartments, or affordable housing development. The ±1.28-acre site provides meaningful scale in one of the most supply-constrained and sought-after residential markets in Los Angeles County. 670 N. Rosemead Boulevard benefits from an abundance of nearby amenities, including dining, retail, grocery, and daily services, making it an ideal location for future residents and current office tenants alike. The property offers excellent connectivity via the 210 and 134 Freeways, with proximity to Old Town Pasadena, Caltech, and the Rose Bowl, further enhancing its appeal as a premier residential or office location. With its existing improvements, by-right high-density residential zoning, and prime Pasadena location surrounded by established amenities, the property presents a compelling opportunity for an office investor, owner-user, or residential developer seeking a versatile asset in one of Southern California’s most desirable submarkets.
