Jurisdiction and research scope
This guide covers unincorporated Maricopa County, Arizona. The City of Maricopa in Pinal County and incorporated cities such as Phoenix and Goodyear have separate guides and rules. Confirm the actual parcel and road authority before applying County yard rules or P-5 posted-street restrictions. Official sources reviewed October 20, 2026; see each answer for limits and special approvals.
Sources and limits for the opening answer are detailed below; parking does not by itself approve sleeping or utilities.

Where can an RV be stored in unincorporated Maricopa County?
Section 814.1.1 places outdoor travel trailers, boats, campers and motorhomes in the side or rear yard, outside the required front yard, while keeping a five-foot clear path around structures. Garage and carport storage are distinguished in the clause. Confirm the required front-yard boundary and the entire approved layout; a postal city or a paved driveway does not answer those questions.
Can the RV briefly use the front-yard area?
The location clause has a loading/unloading exception of no more than 72 hours. That is a private-yard exception, separate from public-street P-5 restrictions. Treat waiting or storage as storage; keep the structure access path clear.
Does P-5 ban RVs on every County street?
No. P-5 §§301–302 and the Clerk note apply the specified restrictions to residential areas posted by County Transportation under Board of Supervisors instructions. On a qualifying posted local or collector street, covered trailers and RVs cannot remain parked except during the stated activities. Confirm road ownership, residential scope and actual P-5 posting.
Why do dimensions matter under P-5?
P-5 §202 defines its RV category using a truck, bus or trailer chassis and a travel-home purpose, with height over eight feet, length over 22.5 feet or gross weight over 10,000 pounds. Trailers are also listed separately in the restriction, so a small trailer is not automatically exempt. A vehicle below every RV threshold still needs all other street controls checked.
Is loading treated differently on a posted street?
P-5 §301 identifies actual loading and unloading and certain maintenance, utility or construction activities. Ordinary empty storage is different. There is no invented street hour allowance in this guide: maintain the qualifying activity and other street controls, and obtain confirmation for a claimed special work exception.
Can someone sleep in a stored RV?
Section 814.1 excludes living, sleeping and housekeeping from ordinary storage. Temporary housing and certain other uses require separate permit review. A front-yard loading window does not convert storage into a guest dwelling, and parking does not establish utility hookup permission.
Is this Maricopa County or the City of Maricopa?
This guide covers unincorporated Maricopa County. The City of Maricopa is a different municipality in Pinal County. Incorporated Phoenix-area cities also have their own rules. Use the County Planning code entry with the parcel address, required yards and any approved plan or permit.
Who to contact for your setup
For an unincorporated County parcel, contact Maricopa County Planning Services at 602-506-3301 or use the online inquiry link on that page. Ask about the required front-yard boundary, proposed storage footprint and any claimed temporary-housing permit. Include the address or parcel number and distinguish empty storage from sleeping; a planning inquiry does not approve a posted-street parking arrangement.
Confirm the exact parcel, vehicle and any special permit with the governing planning or parking authority before relying on an exception.
Use the Unincorporated Maricopa County parking checker to organize the starting conditions. The checker cannot approve a parcel, a variance or an unverified exception.
