In New York City, landlords are legally obliged to accept Section 8 vouchers, which are federal subsidies assisting low-income families with housing costs. This is due to the city's human rights law that forbids discrimination based on an individual's lawful source of income. So, if a potential tenant has a Section 8 voucher, landlords can't reject them solely based on this. However, landlords still reserve the right to deny tenancy based on other legally allowable reasons. Therefore, while the Section 8 program can open doors, it doesn't guarantee an automatic acceptance.
