Sierra Grows to 351,000 SQFT at China Basin’s 185 Berry St., Landing San Francisco’s Largest Office Deal of Q3
Why this matters
Office continues to trade in two distinct markets: trophy assets in walkable submarkets that are leasing at or near record rents, and commodity Class B and C buildings where the basis is still resetting. Underwriting on the latter has moved toward replacement-cost-minus, with credit underwriting now leaning on tenant covenant and remaining lease term rather than mark-to-market expectations. San Francisco continues to clear office at the deepest discounts to 2019 basis seen in the cycle, while multifamily fundamentals have stabilized and life sciences in the Peninsula remains active. For LP-positioned capital, the read-through is that the bifurcation is now a structural feature of the sector, not a cycle to wait out.
