ADUs just became the hottest topic in NYC housing. The city is now letting homeowners turn backyards, basements, and attics into small rental units — up to 25,000 units over the next 15 years. That’s roughly 1,700 units a year for a city of 8 million. Meanwhile, median home prices dropped $55,000 from last summer’s peak and bounced back to $590,000 in a matter of months. That entire move happened while zero ADUs were built. The housing market doesn’t wait for permits. Your data shouldn’t either.
