Executive Summary
NAI NorCal is pleased to exclusively offer the opportunity to acquire a two-property office portfolio strategically located across the San Francisco Bay Area's most dynamic submarkets. This fully stabilized, 100% occupied portfolio totaling ±48,742 square feet and 59 units represents a rare opportunity to acquire institutional-quality assets in Berkeley and San Rafael — two 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 both 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; and the Irwin Street building provides unmatched regional connectivity adjacent to Highway 101 and the San Rafael Transit Center.
With current in-place rents averaging $3.21/SF/month — well below the market rate of $4.30/SF/month — diversified professional tenancy across 59 units, and 100% occupancy, this turnkey investment opportunity offers investors immediate cash flow stability combined with substantial 34% rent growth upside through strategic lease management and operational efficiency.
