Everyone in New York will tell you the city never sleeps. The complaint record disagrees, and it disagrees precisely.

We took every complaint in the city's complaint record for the twelve months ending July 31, 2026 — 3,917,827 of them — and sorted them by the hour they came in. We expected a flat smear. What came out was a clock, and every category keeps its own time.

Complaints by hour created, Aug 2025 – Jul 2026. Peak 10am (234,894); trough 4am (45,359).

Five-to-one, peak to trough. That spread holds across the whole twelve months.

So the intuition is roughly right, the city does quiet down, but not the way people describe it. The dead zone is 2am to 6am, four hours wide, and it is genuinely dead. By 7am the volume has more than tripled off the 4am floor, 45,359 calls to 150,029. By 10am it has peaked. The afternoon is a long slow decline that never quite bottoms out, and then a second, smaller peak arrives at 10pm.

That second peak is the one we kept coming back to. It isn't the same city calling.

The 10pm city

Between 9pm and midnight the mix flips almost entirely. At 10 and 11pm the top four categories are residential noise, illegal parking, street noise and heat. The things that happen to you while you're trying to be home.

Commercial noise is the most nocturnal category in the entire file. Peak hour 10pm, and 29.9% of all commercial-noise calls arrive between midnight and 5am. Nearly a third of them come in during five hours most people are asleep for.

Commercial noise peaks at 10pm on a Saturday. Missed garbage collection peaks at 8am on a Friday.

Share of each category's calls arriving between midnight and 5am.

Parking is the category that refuses to pick a side. Illegal parking peaks at 8am, dips through the afternoon, and then climbs to a second peak at 9pm — 34,835 calls in that hour alone. Blocked driveways do the same thing. Nobody notices the car until they want to leave in the morning or get home at night.

The weekday split confirms the rest. Commercial noise runs 15,090 calls on Saturdays against 4,999 on Tuesdays. A bar block generates three times the complaints on a weekend. Residential noise splits the same way.

If you're looking at an apartment above a storefront, this is the number we'd want. Not whether there's a bar downstairs; you can see the bar. Whether the block generates 10pm calls.

The 9am city

Then there's the other peak, and it's much bigger.

Heat and hot water is the largest maintenance category in New York — 357,067 calls in twelve months. Its peak hour is 9am, with 10am one percent behind it.

Sit with that for a second. The apartment is cold at 3am. The complaint is filed at 9am.

Only 9.4% of heat calls come in between midnight and 5am — roughly 33,600 people who couldn't wait. Everyone else waited. Got up, got the kids out, got to work, called from a desk or a train once the day had started.

The clock isn't measuring when the heat failed. It's measuring when the tenant had a free hand.

Elevators are the extreme version: peak 9am, only 6.1% overnight. An elevator out at 2am doesn't generate a call, because nobody's riding it and nobody's spending their night on hold. Plumbing, paint, water leaks, unsanitary conditions — all peak between 10am and noon, all close to invisible after dark.

Which gives you something useful. A building with a lot of overnight heat calls is a different building from one with a lot of heat calls. My read is that the first one is a building where tenants have stopped believing morning will fix it.

The categories that live in a single hour

A few complaint types are so concentrated they barely count as a distribution.

Missed collection peaks at 8am with 22.1% of its entire year landing in that one hour — the tightest spike in the file. The truck didn't come, you walked out, you saw the bags, you called. Street obstruction: 7am, 8.7%. Illegal dumping: 9am. Dirty conditions: 8am. That's the commuter's-eye view of the city, filed in the first twenty minutes of being outside.

At the other end, helicopter noise peaks at 4pm with 1.1% overnight — the one category with a real curfew, because the aircraft are on a schedule and the complaints follow it exactly.

Rodents peak at 10am, but 6.9% of rodent calls come between midnight and 5am — the highest overnight share of any daytime maintenance category, and it requires no further explanation.

The far end of the file

Sorting 3.9 million calls by hour also means reading the categories nobody ever quotes. New York keeps an official complaint type for things you would not guess were happening at all, and in twelve months somebody used every one of them.

The single most-called exotic animal in the city is the rooster: 444 calls under Illegal Animal Kept as Pet, more than every other animal in that category combined. Also filed: 56 farm animals, 19 snakes, 17 ferrets, six monkeys, and one iguana. Separately, 68 people reported the sale of a turtle under four inches long, which is illegal for salmonella reasons and is apparently still a going concern.

The rooster calls peak at 10am. Not dawn — 10am. Same hour as the heat calls, and for the same reason: the bird woke you at five, and you called when you had a hand free.

Trapping Pigeon1One call, all year

Eighteen people reported a minor receiving a tattoo. Three reported a lifeguard who wasn't certified. Eight people called about a public payphone — four of them to say the phone was blocking the sidewalk, which is a very 2026 problem to have about a payphone.

My favorite is the one-call category. In twelve months, across eight and a half million people, exactly one person picked up the phone about somebody trapping a pigeon.


What to do with a clock

Complaint counts get quoted constantly. This building has 40 calls, that block has 200. On its own the count is close to meaningless without knowing what kind of hour produced it.

Forty daytime maintenance calls is a building with an aging boiler and tenants who report things. Forty 10pm noise calls is a block that will change how you sleep. Same number, different life.

Based on 3,917,827 complaint records filed between August 1, 2025 and July 31, 2026. Hour is the time the complaint was created, in local time.
