Iowa Code § 23A.3: Local purchases.

A city, county, area education agency, or school district shall adopt a policy for purchasing goods or services from private enterprise which requires consideration of purchasing these goods or services from a locally owned business located within the city, county, area education agency, or school district which offers these goods or services if the cost and other considerations are relatively equal. Nothing in this section shall be construed to prevent or prohibit the giving of a preference to businesses owned or operated by minorities or females as may be provided in any other provision of law.
