ADU Rules in Burlington, Iowa

Burlington is the Des Moines County seat with a population of about 24,000 on the Mississippi River in southeastern Iowa. Known for Snake Alley (reportedly the most crooked street in America, beating Lombard Street) and as Iowa's only international seaport, Burlington is a historic Mississippi River city. Iowa has no statewide ADU preemption law — Burlington's local zoning governs.
