If you're staring at a move-out date this fall and dreading the deposit conversation, the honest answer is this: Mount Vernon landlords usually finish deposit returns faster and cleaner, but Bronx landlords who follow the paperwork exactly rarely lose disputes either. The real difference isn't the borough — it's whether you documented the unit, held the money correctly, and hit the deadline. We'll walk through both sets of rules, the actual dollar exposure, and the fall-specific traps we see every year managing turnovers on both sides of the city line.
The Two Deadlines That Decide Everything
The single biggest difference between the Bronx and Mount Vernon is the clock.
- Bronx (New York State GOL §7-103): You have 30 days from lease termination to return the deposit or send an itemized statement of deductions.
- Mount Vernon (Westchester County Chapter 234): You have 5 business days. Not 30. Five.
In our experience managing turnovers in Wakefield and just across the line in south Mount Vernon, this catches new owners every single fall. They close out a Bronx unit on a 30-day rhythm, then apply the same habit to a Mount Vernon property and blow the deadline in a week.
The penalty gap is just as sharp. Miss the Bronx deadline and you're exposed to $10 per day per tenant, plus treble damages — a court can triple the full deposit. On a typical Bronx two-bedroom deposit of $3,150–$3,450, that's a potential $9,450–$10,350 hit before attorney fees. Mount Vernon has no treble-damages clause, but the five-day window means you're far more likely to miss it in the first place.
How Deposits Actually Have to Be Held
This is where we see the most avoidable losses, and it applies in both places.
Under NYC Housing Maintenance Code §27-2005 and GOL §7-103, a Bronx deposit must sit in an interest-bearing escrow account at a New York State–chartered bank — separate from your operating account. Comingling (dropping it into your regular checking to "hold it") triggers a $5 per day per tenant penalty and can force full forfeiture of the deposit back to the tenant, even if they trashed the unit.
Interest accrues at 1% annually on deposits under $10,000 in both jurisdictions. You keep a 1% administrative fee; the rest belongs to the tenant. Owners who forget this line item lose small-claims cases they should have won on the merits.

Where Fall Turnovers Actually Go Wrong
Fall is the second-heaviest turnover season after Labor Day. The disputes we see cluster around four things:
Did you do a real walkthrough — twice?
A move-in walkthrough with photos and a signed condition sheet, and a move-out walkthrough with the tenant present, is the single strongest evidence in housing court. We've watched owners lose $3,000 deposits because they had no move-in photos and the tenant claimed the scuffed floors were pre-existing.
Bring a phone, shoot every room including inside cabinets and appliances, timestamp everything, and email a copy to the tenant the same day. If the tenant refuses to attend the move-out walkthrough, do it anyway and send them the photos with a dated cover letter. That paper trail is what wins.
Did you itemize, or just deduct?
A lump-sum "$1,800 for damages" statement is essentially a losing case. You need line items: "Bedroom carpet replacement, 12x14, $840 (invoice attached). Kitchen wall patch and paint, $220 (invoice attached)." Attach the actual vendor invoices. Judges in both Bronx Housing Court and Westchester County Court throw out unitemized deductions on sight.
Did you separate damage from normal wear?
Small nail holes, minor scuffs, faded paint after three years, worn carpet in traffic paths — these are normal wear and tear and cannot be deducted. Actual damage means broken tiles, pet urine soaked into subfloor, holes in drywall, missing fixtures. When we train new owners, this is the line that saves them the most money — over-deducting invites the treble-damages claim.
Did you hit the deadline?
30 days in the Bronx. 5 business days in Mount Vernon. Put it in your calendar the day the tenant hands back the keys. This is the same discipline that helps you collect full security deposits during Labor Day turnover — the calendar rules the outcome.
The Housing Court Reality If It Goes Sideways
If a dispute becomes a filing, the two jurisdictions look very different.
The Bronx had 18,473 housing-court filings in 2023, roughly 62% involving non-payment or deposit disputes. Typical case length: 60–120 days. Westchester processes similar cases in 45–90 days. Filing and attorney fees on a contested deposit case run $500–$1,200 — often more than the disputed amount itself.
And if you're also dealing with a non-payment overlay, ERAP notice requirements can add another 30–60 days to the Bronx timeline before you even get to the deposit question. Cash flow-wise, a poorly documented Bronx turnover can tie up capital for four to six months.
The same documentation discipline that protects your deposit also protects you from $8,000+ eviction costs on the front end.
Side-by-Side: What Each Fall Turnover Actually Looks Like
| Item | Bronx | Mount Vernon |
|---|---|---|
| Deadline to return deposit | 30 days | 5 business days |
| Escrow required | Yes, NYS-chartered bank | Yes |
| Interest rate to tenant | 1% annual | 1% annual |
| Late-return penalty | $10/day + treble damages | Statutory only, no treble |
| Comingling penalty | $5/day + full forfeiture | Return + interest |
| Court timeline if disputed | 60–120 days | 45–90 days |
| Typical 2BR deposit (1.5 mo rent) | $3,150–$3,450 | $3,600–$3,825 |
Which Landlords Actually Come Out Ahead This Fall
Across both jurisdictions, the owners who close fall turnovers without a dispute share the same habits: dated move-in and move-out photos, a proper escrow account, itemized deduction letters with invoices attached, and a hard calendar reminder for the return deadline. Boroughs don't decide the outcome — the folder of paperwork does.
If a 3 a.m. move-out call has ever ruined your week, you're not alone. DoryAngel's owner dashboard tracks deposit deadlines, escrow interest, and turnover documentation automatically for every unit — so nothing quietly runs past the 5-day or 30-day window while you're focused on the next tenant.
