The housing landscape in Iowa, particularly around Davenport, is characterized by a prevalence of single-family detached homes, making modular accessory dwelling units an effective strategy for homeowners seeking to enhance their property's utility and value. Modular construction's controlled factory environment allows for precise fabrication, which is advantageous in mitigating the impacts of Iowa's extreme seasonal temperature fluctuations on building quality. It is imperative to address foundation design to accommodate potential frost penetration during winter months and to select building envelopes that offer superior thermal resistance and moisture control to combat both winter cold and summer humidity. Adherence to the Iowa State Building Code and any specific amendments enacted by the City of Davenport is a cornerstone of our project execution.
