Aircraft operational noise is governed exclusively by the Federal Aviation Act and FAA regulations, preempting Iowa cities and counties from imposing flight-path or in-flight noise restrictions; Iowa Code Chapter 328 frames state aviation authority around airport operations.

Iowa Code 364.3(12) restricts how cities may regulate rental property. Cities cannot impose registration, licensing, or inspection requirements on rental manufactured or mobile homes unless the same standards apply to other rental housing. Cities may still inspect rental units, but state law constrains the scope of registration programs.
