Professional ADU Builders with Local Atlanta Knowledge
Accessory Dwelling Units (ADUs) come in a variety of forms, each with its own unique characteristics and benefits. Whether you’re familiar with terms like “granny flat,” “in-law suite,” or “guesthouse,” or you’re hearing about ADUs for the first time, this guide will walk you through the most popular types of ADUs and what they offer.
While the term “Tiny House” might often come up in your research, it’s important to distinguish it from traditional ADUs. Tiny houses are typically mobile and off-grid, whereas ADUs are permanent structures that add significant value to your Atlanta property.
why ADUs are a
recession-beating
investment
For Retirees
Instead of moving into a costly senior living community, retirees in Atlanta can downsize into an ADU while renting out their primary home for additional income. This approach provides financial stability while allowing them to stay close to family.
Homeowners
ADUs offer a practical solution for multi-generational living. Whether it’s aging parents, adult children, or other family members, an ADU creates a separate living space that enhances privacy while keeping loved ones close.
Investors
Renting out an ADU, either as a long-term rental or through platforms like Airbnb, can generate substantial income. This added revenue stream can help offset mortgage costs, property taxes, and other expenses, making it a smart move in uncertain times.

They can be a flexible space for guests, a home office, or a rental unit. Due to their smaller footprint, they may have fewer permitting requirements, especially if they lack plumbing.

Because they often lack full living amenities, permitting is usually simpler and faster in Atlanta.
Typical Size: 200-400 sq ft
Features: No plumbing, used as a studio or workspace
Permitting: Easier permitting process in Atlanta due to lack of plumbing
