Understanding ADUs: The Flexible Housing Revolution

An Accessory Dwelling Unit (ADU) is a secondary housing unit created on a single-family residential lot. You might know them as granny flats, in-law suites, or backyard cottages. ADUs come in various forms – they can be attached to the primary dwelling, detached on the same lot, or a converted interior space.

The benefits of ADUs are multi-fold – homeowners may use them to house aging parents or adult children, provide rental income, or offer accommodation for caregivers or guests. They can also contribute to the housing supply, particularly in urban areas where land availability is scarce.

In DeKalb County, the surge of remote work and the ongoing need for affordable housing options make ADUs a compelling solution. But before you dig into the details of building one, it's crucial to understand what local Georgia law permits and prohibits.

DeKalb County Regulations on ADUs: What You Need to Know

DeKalb County’s regulations on ADUs are clear and specific. Understanding these rules is vital for any homeowner considering the construction of an ADU.

• Eligible Property Types: On parcels zoned for residential single-family dwellings, an ADU can be allowed as an attached structure, detached structure, or within the existing house.
