Some renters may savor the convenience of "smart home" technologies like keyless entry and internet-connected doorbell cameras. But tech companies are increasingly selling these solutions to landlords for a more nefarious purpose: spying on tenants in order to evict them or raise their rent. Teman, a tech company that makes surveillance systems for apartment buildings ... proposes a solution to a frustration for many New York City landlords, who have tenants living in older apartments that are protected by a myriad of rent control and stabilization laws. The company's email suggests a workaround: "3 Simple Steps to Re-Regulate a Unit." First, use one of Teman's automated products to catch a tenant breaking a law or violating their lease, such as by having unapproved subletters or loud parties. Then, "vacate" them and merge their former apartment with one next door or above or below, creating a "new" unit that's not eligible for rent protections. "Combine a $950/mo studio and $1400/mo one-bedroom into a $4200/mo DEREGULATED two-bedroom," the email enticed. Teman's surveillance systems can even "help you identify which units are most-likely open to moving out (or being evicted!)." Two affordable New York City developments made headlines when tenants successfully organized to stop their respective owners' plans to install facial recognition systems: Atlantic Towers in Brooklyn and Knickerbocker Village in the Lower East Side.
