Maricopa County, AZ Parking Rules: Curb Color Rules (2026)

ARS section 28-873 authorizes any local authority, including the Maricopa County Board of Supervisors and Maricopa County Department of Transportation (MCDOT), to designate parking restrictions by signs or curb markings on county-maintained roads. Arizona has no statewide curb color statute, so the county follows the convention used statewide and adopted by Phoenix and Mesa: red curbs prohibit stopping, yellow curbs allow active loading and unloading only, white curbs permit passenger pickup or drop-off no longer than three minutes, and blue curbs reserve disabled parking with a state-issued placard. Markings must be paired with R7 or R28 series signs to be enforceable. Private parties may not paint a public curb without an MCDOT encroachment permit.
