New York City

So, you requested your rental history. DHCR mailed you the record. Now you’re scratching your head. How do I read this rental history? Am I rent-stabilized? Was my apartment legally deregulated?

NYC’s First Rent Stabilization Map

As of June 11, 2025, the FARE Act is officially the law in New York City. Despite some efforts to block it in court, a judge has ruled that enforcement can move forward. That means renters can no longer be charged broker fees if the broker was hired by the landlord.

The FARE Act Is Now In Effect: What Does It Mean for Renters?

Renting an apartment in New York is not easy. Housing is competitive, prices are volatile, and applications are invasive. First-time renters may be overwhelmed by how much information brokers and landlords ask for. At openigloo, we often get messages from renters asking us what’s normal for an NYC rental application checklist, as handing over dozens of personal documents to a stranger feels weird. But rest assured, these kinds of requests are very common.

NYC Rental Application Checklist: 8 Things You Need!

Many renters dread renewal time – and for good reason. Getting huge rent increases is not uncommon in New York City. We get a lot of messages from renters asking us if they should renew or negotiate. We think renters should always try to negotiate their rent. Our position is that you don’t get what you don’t ask for. Keep in mind, if you have a stabilized or Good Cause apartment, you don’t need to worry about steep increases. The law limits how much the landlord can increase the rent. But for everyone else – landlords can increase the rent to whatever they want.
