Prime Multi-Property - Redstone, Solano, Irwin
851 Irwin Street, San Rafael, CA 94901
NAI NorCal is pleased to exclusively offer the opportunity to acquire a three property office portfolio strategically located across the San Francisco Bay Area's most dynamic submarkets. This fully stabilized, 100% occupied portfolio totaling 104,302 square feet represents a rare opportunity to acquire institutional-quality assets in Berkeley, San Rafael, and San Francisco's Mission District—three of the region's most sought-after office markets.
The portfolio has been substantially upgraded under current ownership with
comprehensive capital improvement programs completed across all three properties, including HVAC modernization, interior renovations, security enhancements, and building system upgrades. These recent investments have positioned the portfolio for continued strong performance with minimal near-term capital requirements while creating significant rent growth upside as leases roll in each market.
Each property benefits from exceptional location fundamentals: the Solano
Avenue asset sits in Berkeley Hills' historic main thoroughfare with a Walker's
Paradise Score of 94/100; the Irwin Street building provides unmatched regional connectivity adjacent to Highway 101 and the San Rafael Transit Center; and the landmark Redstone Building occupies a premier Mission District location one block from BART with exceptional Walk/Transit/Bike Scores of 99/98/99.
With current in-place rents averaging well below market across the portfolio,
diversified professional tenancy spanning 127 suites, and 100% occupancy, this turnkey investment opportunity offers investors immediate cash flow stability combined with substantial value-add potential through strategic lease management and operational efficiency.
