Is 350 7th Avenue rent stabilized?
The honest answer is: it depends on your apartment's registration history with NYS HCR — not on what your lease says. Run the free check below to find out, and to see whether you may be owed thousands in recoverable overcharges.

What we look for at this kind of building
350 7th Avenue sits in Park Slope — a stretch of Brooklyn where rent overcharges are common.
Most pre-1974 buildings in Park Slope have at least some rent-stabilized units, and many post-1974 buildings here received tax abatements (J-51, 421-a) that quietly added stabilization protection. The result is that "free market" leases in this neighborhood are often less free than landlords claim.
The patterns we look for
Whether your unit is registered as stabilized or marketed as “free market,” the same handful of overcharge patterns show up over and over:
- Illegal deregulation — typically through J-51 abuse, inflated IAI claims, or stacked vacancy bonuses. Read the deep dive on J-51 deregulation.
- Inflated IAI charges — landlord claims $40K of renovations that never happened to push rent past the deregulation threshold. (How IAI fraud works.)
- Vacancy bonus stacking — multiple short tenancies between long ones, each claiming a 20% bonus to crank up the rent. (Vacancy bonus fraud.)
- Non-RGB rent increases — annual increases that exceed what the Rent Guidelines Board allowed for that year. Common when a landlord assumes nobody will check.
- Missing rent registrations — landlord stops filing annual registrations, then raises rent. Default formula applies and rent rolls back.
What recovery looks like
Under HSTPA, you can recover the difference between what you paid and the legal regulated rent for the six years preceding your complaint. Overcharges within the most recent two years can be trebled (3x) if the overcharge was willful. Average recovery for our clients is over $22,000. Cases at 350 7th Avenue-style buildings — pre-war stock with active landlord turnover — frequently land in the higher tier.
