Tenants at Slate Property Group’s Upper West Side apartments at 600 Columbus Avenue are accusing the owner of “inhuman displacement.” Residents report abrupt lease non-renewals, renewals at significantly higher rates, or the possibility of temporary displacement for unit renovation. Slate acquired the 166-unit rental property a year ago for $120 million. Some tenants claim asking rents have increased by roughly 60%, with apartments that were $5,000 a month now at $8,200. While Slate stated the average change to market-rate leases has been 8.6%, residents dispute this figure. A group of residents is exploring legal strategies regarding Slate’s actions.
