Portland Tows Cars in July Too: The Street Maintenance Rules Nobody Reads
August 26, 2026
Everyone knows about the snow ban. Far fewer people know about the overnight restriction that runs eight months of the year, the daytime sweeps, or the ten-day rule.
The overnight restriction is not a winter thing
Portland restricts overnight parking on the peninsula so that crews can sweep, clean catch basins and plow. The City sets that window at 12:01 am to 7 am, and the restrictions run from October 1st through May 31st.
There is one significant exception, and it is the busiest part of the city. Area 3, the Old Port, is enforced year round. A car parked overnight on an Old Port street in July is subject to the same restriction as one parked there in January, which is why summer visitors account for a healthy share of the tows.
The restriction is posted rather than assumed. The City directs people to look for the red and white signs posted every 250 feet, and it is explicit that the signs on the street govern.
Nine areas, and the even-odd rule that is not always true
The peninsula is divided into nine street maintenance areas: West End and Cemetery, Arts and Civic Center, Old Port and Commercial Street, Munjoy South Side, West End and Hadlock, Parkside, Bayside and City Hall, Munjoy North and Bayside, and the Nathan Clifford section of USM.
Each area has its own schedule, and the City publishes them by area rather than as one citywide rule. That is the part people get wrong: knowing the rule for the street you used to live on tells you nothing about the street you are on now.
The City also adds an unusually honest caveat. It notes that references to the even side and the odd side of the street are generally accurate, but that not every street follows the pattern, and that the signs as posted are what count. If the sign and your memory disagree, the sign wins.
The daytime sweeps catch people who never park overnight
Two daytime exceptions run outside the overnight window entirely. The City lists 10 am to 2 pm on Tuesdays on the East End, and 10 am to 2 pm on Thursdays in parts of the Parkside and Bayside neighborhoods.
Those four-hour windows land in the middle of a working day, which means the vehicle most likely to be caught belongs to somebody who parked legally at 8 am and came back at 5 pm. Again the answer is the red and white signs, posted every 250 feet.
The ten-day rule
One line in the City's restrictions is easy to miss and catches a specific kind of owner: no vehicle may stay in the same space for more than ten consecutive days.
That is aimed at storage rather than parking, and it snares second cars, project cars, vehicles left while their owner travels, and cars belonging to somebody who has stopped driving. If a car is going to sit for a fortnight, the street is not where it should sit.
A vehicle that has to be moved but cannot start after two weeks in the weather is a tow, not a walk. That is the most common version of this call, and arranging towing in Portland is quicker than trying to revive a car that has been sitting since before the last storm.
Construction and event bans are called with almost no notice
On top of the standing rules, Portland calls temporary bans for construction and events, and those go up on a few days' notice rather than a season's. The City runs them as alerts on its own website, and they are usually specific to one street and one date range.
The practical defense is the same as for the winter ban: sign up for the City's notifications, and read the temporary signs on the block where you park rather than the permanent ones. A temporary sign zip-tied to a pole outranks the painted rule underneath it.
For the winter version of all this, the Portland snow ban towing guide covers the zones, the hours and the lots that open up.
If the car is already gone
A car removed under a street maintenance restriction goes the same way as a snow ban tow: to a private operator's impound lot, with fees and a ticket attached. The City's Parking Division is the starting point rather than the tow companies.
What it costs and how to find the car is set out in full in the guide to Portland impound fees and finding a towed car, including the payment methods the lots will and will not take.

Quick Answers
Does Portland's overnight parking restriction only apply in winter?
No. The peninsula restrictions run October 1st through May 31st, but Area 3, the Old Port, is enforced year round. The overnight window is 12:01 am to 7 am.
How do I know which street maintenance rule applies to my street?
By the red and white signs posted roughly every 250 feet. The City divides the peninsula into nine areas with different schedules, and notes that even-side and odd-side descriptions are generally accurate but not universal, so the posted sign governs.
How long can a car stay parked in one space in Portland?
Under the street maintenance restrictions, no vehicle may stay in the same space for more than ten consecutive days.
