In the last decade, apartment inventory has climbed nearly 37% in Des Moines as the small market added just under 15,000 apartment units since 2012. The Iowa market has been slowly and steadily adding new apartments over the last year, most prolifically in the 2015-2018 development boom, though construction has generally been modest and digestible. From a submarket level, all four of Des Moines submarkets have grown in the last 10 years, but to varying degrees, according to data from RealPage Market Analytics. South Des Moines/Warren County has only grown its existing unit count by about 7.6% in the last 10 years, while Northeast Des Moines/Ankeny has grown by a whopping 62.3%. Northwest Des Moines/Urbandale has grown by about 20.9% and West Des Moines/Dallas County has grown by about 48% during that time.
