Van life in the United States: rules, registration and stays

What a van traveller needs to know for the United States — camping legality, self-containment, weight and licence rules, and where federal, state and city law actually draw the line. Curated from official sources, pending review.

At a glance

	Topic	United States
Overnight camping	—	BLM/USFS dispersed camping allowed by default; stay limits set locally (commonly 14 days), never nationwide
Self-containment	—	No federal certification or register — a dense public/commercial dump-station network instead
Weight & licence	—	No federal CDL for private use at any weight; some states add their own non-commercial heavy-vehicle classes
Emissions / access	—	No emission zone anywhere; NYC's congestion charge is class-and-time based, not emissions-based
Registration	—	State-by-state conversion process — Florida, Washington, Texas and South Dakota each run a different path

In practice

Dispersed camping on Bureau of Land Management land is allowed unless posted closed, and BLM's own national guidance cites a 14-days-in-any-28-day pattern — but the same guidance says limits vary by state and field office: Nevada mirrors the 14/28 rule, while California's Bishop Field Office caps dispersed camping at 14 days per year. The US Forest Service has no single national limit either: Apache-Sitgreaves (Arizona) and George Washington & Jefferson (Virginia) run 14 days in 30, Black Hills (South Dakota) runs 14 in 60. Walmart's corporate FAQ permits RV parking on its lots "as we are able," extended per store and expressly subordinate to local law — not a guaranteed right. City ordinances are the binding constraint on urban van sleeping: after City of Grants Pass v. Johnson (2024), the Supreme Court held that enforcing generally applicable public-camping bans does not violate the Eighth Amendment, giving cities a freer hand to restrict overnight parking and camping within their limits.

The widely repeated "26,000 lb / CDL" rule is almost always reported wrong. Under 49 CFR § 383.5, a commercial motor vehicle — the thing that triggers a CDL — is one "used in commerce"; FMCSA guidance states plainly that non-business drivers need no CDL "unless the state of licensure requires it." A privately used motorhome, however heavy, needs no federal CDL — the real answer for a heavy Class A owner is whatever non-commercial licence class their own state imposes. On emissions, California's Advanced Clean Fleets rule — which would have pushed commercial fleets toward zero-emission — had its EPA waiver request withdrawn by CARB on 13 January 2025, and it never applied to private vehicles regardless. New York City's Congestion Relief Zone tolling, live since 5 January 2025 south of 60th Street in Manhattan, charges by vehicle class and time of day, not by Euro or emissions standard; which class band a campervan falls into is not settled by the public rate schedule, so check the MTA's own toll calculator before assuming a figure. Titling a self-converted van as an RV is entirely a state matter — Florida (TL-13 conversion affidavit), Washington (habitation + exclusive-recreation-use test), Texas (assembled-vehicle eligibility letter) and South Dakota (dedicated converted-housecar title path) each run a distinct process; there is no single national rule for grey/black water disposal either — it sits in state and local health codes, so check locally rather than assuming a national standard.

Key takeaways

BLM/USFS dispersed camping is real but capped locally — commonly 14 days in 28, sometimes 14 in 30 or 60, or as little as 14 per year (Bishop, CA) — never a single national number.
City of Grants Pass v. Johnson (2024) freed cities to enforce anti-camping ordinances again; city law, not federal or state law, decides urban van sleeping today.
There is no federal CDL requirement for a privately used motorhome at any weight — the "26,000 lb rule" defines a commercial vehicle "used in commerce," not a private-driving limit; states may still add their own non-commercial classes.
No US city runs a European-style low-emission zone; NYC's congestion charge (live since 5 January 2025) is based on vehicle class and time of day, not emissions, and CARB withdrew its Advanced Clean Fleets waiver request in January 2025.
Titling a self-build as an RV is entirely state-run — Florida, Washington, Texas and South Dakota each verified here use a different process; do not assume one state's rule applies elsewhere.
There is no single legal rule for grey/black water disposal — it is governed by state and local health codes, so check the relevant state or county rule rather than assuming a national standard.
