It is legal to sleep in your car in Portland, Oregon, but there are some restrictions. Here are a few things to keep in mind:

• You can’t park your car overnight on the street in residential areas.
• If you’re parked in a public lot or on the street in a non-residential area, make sure you’re not blocking any sidewalks, driveways, or fire hydrants.
• You also can’t park your car in a park overnight unless it’s a designated camping area.
• Most rest areas have designated parking areas for cars, trucks, and RVs. Some rest areas have specific hours for overnight parking.
• You can’t park in any restricted areas, such as near building entrances, on sidewalks, or in front of restrooms.
• Some rest areas may have limits on how long you can park, so be sure to check the posted signs.
• You should also make sure you’re following all other local laws and regulations, such as noise ordinances, littering laws, and fire safety rules.

In general, sleeping in parks overnight is generally not allowed in Portland. Most city parks have designated hours of operation and sleeping in parks is typically prohibited during those hours. However, the specific regulations can vary depending on the park, so it’s best to check the rules and regulations of the specific park you’re interested in or consult with the city’s Parks and Recreation department for more information.

It’s important to also keep in mind that camping in public parks is generally not allowed in Portland, as it can create safety concerns for park visitors and can also lead to damage of park resources. There are designated camping areas and shelters for those in need, so it’s best to check with local organizations or government agencies for information on alternative options for overnight accommodation.
