What is an ADU — and Why Alexandria Homeowners Are Building Them
An Accessory Dwelling Unit (ADU) is a secondary, self-contained living residence located on the same lot as a standalone single-family home. In Alexandria, VA, ADUs have become one of the most lucrative and flexible home investments available.
The City of Alexandria allows detached accessory structures, garage conversions, and basement apartments. With strong rental demand near Old Town and Metro corridors, Alexandria ADUs generate outstanding long-term rental income.
