After Des Moines, Iowa, updated its zoning code to legalize accessory dwelling units (ADUs), an AARP Community Challenge grant helped fund the city's first ADU, which a local nonprofit developed as a demonstration for homeowners hoping to build their own.

"Accessory Dwelling Units — What They Are, What They Can Do" is a one-page, easily shareable PDF that explains what ADUs are (and aren't) and how they benefit people of all ages.

This page is an entry point to AARP's array of ADU content and resources for residents, local leaders, policymakers and others.
