Arizona county laws

Select your county on the map or in the list. Each county page links to the official county code and meeting agendas, and lists recent ordinances and resolutions, in plain language where a summary has been written. County laws change often, and the official source is always the authority.

Good to know: Arizona counties are governed by an elected Board of Supervisors. Arizona counties have limited law-making power, mainly over unincorporated areas (for example zoning, building and public health), and many publish few ordinances online.
