The Iowa contractor market report
13,624 covered roster records from Iowa DIAL (Department of Inspections, Appeals & Licensing). Recorded source refresh: 2026-09-02. The separate trade breakdown below covers 13 categories.
Figures use separately generated snapshots: overall roster totals, trade counts and mapped-city counts can differ in scope and collection time and should not be added together or treated as a reconciled census. The displayed source refresh date does not date every aggregate. Population and households are sums of the covered ZIP estimates. The income indicator is a population-weighted average of ZIP-level household-income medians, not the state's household median. Census context can refer to a different period from the roster. Housing-unit authorizations refer to the displayed permit year; they are not completed projects. See the ACS estimate guidance and Building Permits Survey for the underlying statistical definitions.
