Alternate Side Parking NYC Explained: How It Works and How Not to Get Burned

By NY Unscripted · Parking

Alternate side parking is the thing New York City drivers either have memorized cold or completely misunderstand — and the difference between those two groups shows up on their windshields.

It sounds simple: move your car so the street sweeper can clean the curb. In practice, it has enough nuances, exceptions, and unwritten local rules that it trips up visitors, new residents, and even long-term New Yorkers.

What Is Alternate Side Parking and Why Does It Exist?

New York City has over 6,000 miles of streets. Street sweepers need one side of the block clear of parked cars to do their job. ASP is the system that clears it — on designated days and hours, parking is prohibited on one side of a street so the sweeper can pass. The restriction alternates between sides on different days, hence the name.

How to Read an Alternate Side Parking Sign

A sign reading “NO PARKING 8AM–9:30AM TUE & FRI” means: on Tuesday and Friday mornings only, between 8:00am and 9:30am, you cannot be parked on that side of the street. At any other time, on any other day, that sign does not apply.

For a full breakdown of every sign type, see our complete guide to reading NYC parking signs.

What catches people up:

• The window varies — most restrictions run 90 minutes, some run 3 hours; the sign tells you exactly
• Each side is different — the opposite side has its own sign with different days and hours
• No days listed means every day
• Multiple signs on one block — the more restrictive one governs

ASP Hours by Borough

To find exact rules for a specific block, use the NYC DOT Parking Sign Locator at nyc.gov/dot. For the full picture across all five boroughs, see our complete NYC parking guide.

The 5-Minute Grace Period

NYC Administrative Code § 19-213 gives every driver a mandatory 5-minute grace period after an ASP restriction begins. No ticket can legally be issued until 5 minutes after the posted start time — and the same grace period applies at the end of a restriction.

The ASP Ticket Cost

A 25% late penalty applies automatically if unpaid within 30 days. After 90 days the ticket goes to judgment.

The Double-Parking Dance: What Locals Do

In many residential neighborhoods, when ASP begins, locals don’t leave the block — they double-park on the opposite side, sit in their cars, and wait for the sweeper to pass. Once it goes by, usually within 30–45 minutes, they pull back into their original spots. You’ll see this on block after block in Brooklyn and Queens.

If getting towed is a concern, read our full guide on what happens when your car gets towed in NYC.

What to Do If You Get a Street Cleaning Ticket

• Check the grace period first — if issued within 5 minutes of the start time, contest it
• Check if the sweeper actually ran — in rare cases this is contestable
• If neither applies, pay within 30 days to avoid the 25% late penalty

ASP During Snow and Emergencies

When NYC declares a snow emergency, ASP is typically suspended to keep cars off streets for plows. Important: this only lifts the street-cleaning restriction — meters, No Standing zones, and hydrant rules still apply. Always check 311 or NYC DOT’s social accounts for real-time status; don’t assume ASP is suspended just because it’s snowing.

How to Never Get an ASP Ticket

• Know your block — the specific days and hours for wherever you park overnight; set a phone alarm 15 minutes ahead
• Check the suspension calendar — NYC suspends ASP on dozens of holidays a year, but not every holiday triggers one
• Use the best parking apps — SpotAngels shows street-by-street ASP schedules in real time
• When in doubt, use a garage — one ASP ticket costs more than a few hours of garage parking in most outer-borough neighborhoods

ASP rules, hours, and suspension calendars can change. Always verify current rules through nyc.gov or 311 before relying on any block’s schedule.
