In Iowa, and specifically in Des Moines, the construction of Accessory Dwelling Units (ADUs) is influenced by a continental climate with cold winters and warm, humid summers. This seasonal variation dictates the optimal times for exterior construction phases.
Iowa's ADU development is guided by state building codes and local municipal ordinances, which can vary across different cities. The housing stock in areas like Des Moines is largely composed of single-family homes, positioning ADUs as a practical solution for increasing housing options. Scheduling foundation work and exterior framing around the ground-freezing temperatures of winter is a primary consideration.
