Phoenix Single-Use Items: Polystyrene Foam Rules Rules (2026)

Some Restrictions

Recently verified

Arizona state rule: Phoenix does not have a local ordinance for polystyrene foam rules. This topic is governed by Arizona state law and applies uniformly across the state.

Summary

Arizona preempts local bans and fees on polystyrene foam food containers as auxiliary containers under ARS 9-500.38 and ARS 11-269.16.

Full Breakdown

Polystyrene foam clamshells, cups, and trays are categorized as auxiliary containers under state law, meaning municipalities and counties cannot ban their use, distribution, or sale. The preemption extends to taxes, fees, and recycling mandates that target specific container materials. Restaurants, grocers, and food vendors retain the choice to use polystyrene unless federal or state regulations apply. Solid waste plans may encourage reuse but cannot prohibit polystyrene packaging.

Local polystyrene bans are void, and adopting jurisdictions risk reduced state shared revenue and litigation costs.

Frequently Asked Questions

Can a city ban polystyrene takeout containers?

No. State law preempts local bans on polystyrene foam containers, even for restaurants on city property leases generally.

Are state agencies bound by the preemption?

The preemption applies to local political subdivisions; state agencies follow procurement rules separately.
