Is it illegal to sleep in your car?

Short answer: No national law bans it. Whether you can sleep in your car depends on who controls the place you park (a federal agency, the state, the city or a private owner) and on state law, which can apply anywhere in the state, as California’s does. On a national forest, a night in your car counts as camping and is limited to the days a forest order allows [1][3]. Cities such as Eugene and Medford in Oregon ban using a vehicle as a temporary place to live on their streets and in public lots [10][12].

National forests, parks and BLM land: camping rules and stay limits

Forest Service regulations count your car as camping equipment. They define camping as “the temporary use of National Forest System lands for the purpose of overnight occupancy without a permanently-fixed structure,” and camping equipment as including “any vehicle used for transportation” [3].

Each national forest sets the stay limit for dispersed camping by order. Federal regulation prohibits camping longer than an order allows but leaves the number of days to the forest [1], so limits differ from forest to forest. A separate rule prohibits “occupying or using a residence on National Forest System lands” without a special-use authorization [2].

On BLM land, the regulation forbids camping longer than the authorized officer permits [4]. The BLM says dispersed camping is generally limited to 14 days within any 28-day period, after which you must move, often at least 25 to 30 miles [5]; individual forests and field offices set their own stay limits.

National Park Service rules define camping to include “parking of a motor vehicle, motor home or trailer … for the apparent purpose of overnight occupancy” [6], and they prohibit “camping outside of designated sites or areas” [7]. A park pullout or trailhead lot is not a place to sleep unless the park has designated it for camping.

Rest areas: state time limits and camping bans

Each state sets its own rest-area rule: of the 12 states in our rest-stop comparison, most cap the stay and ban camping, and Tennessee and Virginia allow no overnight parking at all.

City codes can ban living in a vehicle

Eugene’s camping ban reaches cars because its code counts a vehicle used as a temporary place to live as a campsite:

The Eighth Amendment no longer stops cities in the Ninth Circuit states, including Oregon and California, from enforcing these bans when shelter beds are short, though a city’s own code can still make exceptions, as Ashland’s does [13]. In the 2024 case from Grants Pass, Oregon, the Supreme Court’s syllabus summarizes the holding: enforcing “generally applicable laws regulating camping on public property” does not violate the Eighth Amendment’s ban on cruel and unusual punishment [14]. The Court reversed the Ninth Circuit, whose rule from *Martin*, a Boise case, had barred such enforcement against homeless people whenever they outnumbered available shelter beds [14]. Oregon adds its own limit: ORS 195.530 requires any city law regulating “sitting, lying, sleeping or keeping warm and dry outdoors on public property” to be “objectively reasonable as to time, place and manner with regards to persons experiencing homelessness” [19]. The statute does not say whether sleeping in a vehicle counts as sleeping outdoors.

Sleeping in a private or business lot

On private property you need the owner’s permission, and city code can limit what the owner allows. Eugene’s code requires a host lot to provide sanitary facilities, forbids charging, and lets the owner revoke permission at any time, after which you must leave [11]. Online lists of stores that allow overnight parking are crowdsourced; ask the store manager, or check the chain’s published policy, before you park.

If you are living in your car

If your car is where you sleep because you have nowhere else to stay, 211 is the national starting point: call 211, or use the local-211 finder on 211.org, for help with housing, food and emergencies. Every call is confidential [16]. Ask about safe-parking and host-lot programs as well; Eugene, Medford and Ashland write them into city code [11][17][18]. National forests and BLM land allow short-term camping within stay limits, not living there [2][5].

How to check the rule where you are

• National forest: the forest’s alerts page for a stay-limit or occupancy order, or the ranger district.
• BLM land: the field office for that area.
• Rest area: the state’s rule and the signs at the rest area.
• City street or public lot: the city’s municipal code. Search it for “camping”, “vehicle” and “habitation”, and read the definitions, since a camping ban can reach a car through how it defines a campsite. If the code is unclear, ask the city’s parking or police department.
• Private lot: the owner or manager, before you park.
