About Atlanta ADU Builder

What Is an Accessory Dwelling Unit?

Accessory Dwelling Units (ADUs) are secondary housing units built on a single-family residential lot. They come in many forms, including granny flats, in-law cottages, guesthouses, carriage houses, and backyard cottages. These versatile spaces are ideal for accommodating family members, generating rental income, or creating a personal retreat right on your own property.

Atlanta ADU Builder is a dedicated ADU contractor and accessory dwelling unit builder serving the greater Atlanta area. They specialize in customizing these units to fit each homeowner's specific needs, ensuring that every new ADU feels like a natural extension of the existing home.

A Legacy of Experience in Real Estate Development

Since 2001, the team at Atlanta ADU Builder has been at the forefront of real estate development and construction. Over more than two decades, they have built a solid reputation for quality, integrity, and innovation — growing from constructing and renovating homes to developing estate properties, small subdivisions, and commercial projects.

Their international experience across South America, the Caribbean, and Europe has given them a deep understanding of making small spaces feel spacious, luxurious, and comfortable. Building carriage houses and guesthouses behind grand estate homes allowed them to refine the art of creating smaller yet high-quality living spaces. This expertise, combined with work on eco-resorts and micro-resorts abroad, directly informs their approach as a backyard cottage builder and detached ADU builder in Atlanta today.

This background has also given them a strong grasp of generational living — a concept that is increasingly popular across the United States and one that ADUs are uniquely positioned to support.

As a full-service ADU builder, Atlanta ADU Builder manages every aspect of a project from start to finish. Unlike companies that act as resellers of services, they are the actual developers — bringing unparalleled expertise and transparency to every build.

Custom ADU Types and the Building Process

Atlanta ADU Builder offers a range of ADU solutions tailored to different property types and homeowner goals. One popular option is the backyard cottage — a standalone unit ideal for smaller lots. These compact structures typically include:

  1. A living area, bedroom, bathroom, and kitchenette
  2. Usable loft space for additional flex space or a bunk room
  3. Typical size range of 250–500 sq ft
  4. Streamlined permitting for units without plumbing

Their process is structured and transparent. After an initial consultation, a retainer agreement is signed to secure the project. From there, the team conducts an initial site survey, develops full architectural plans, and completes a final site survey to precisely situate the ADU on the property. Once all plans and surveys are finalized, they prepare and submit the complete permit package to Atlanta's planning and permitting department.

Navigating local zoning regulations is a critical part of every ADU project. ADUs must comply with local zoning laws covering lot size, setbacks, maximum unit size, and height restrictions. Atlanta ADU Builder specializes in the zoning regulations of the following counties:

  1. Fulton
  2. Bartow
  3. Cherokee
  4. Cobb
  5. DeKalb
  6. Forsyth
  7. Gwinnett

Whether a property falls under city zoning guidelines or county regulations for unincorporated areas, Atlanta ADU Builder ensures full compliance every step of the way. As Atlanta continues to grow in value and evolve as a city, their role as a trusted granny flat builder and in-law suite builder positions them as a key partner for homeowners looking to maximize the potential of their properties.

"Corey is very knowledgeable of all the processes involved in building ADUs. He met with me, assessed my site and listened well about my needs, then researched Dekalb County requirements. unfortunately, the setback requirements didn't work for my needs. Corey was persistent in exploring options."

"The team at Georgia ADU are so professional and absolutely amazing. They took the time to sit with us and come up with a plan, with multiple options, that could work for our needs."

"Love this team!! I unfortunately suffered a catastrophic loss on a home and had to do a full rebuild. Being a sloped property on the side of a hill brought in a lot of extra complexity. The Georgia ADU team was extremely effective at ensuring the plans were structurally sound and that the project was done in a timely manner with our overall goals and budget in mind. I will trust them with all future projects!"

"We have worked with the team at Georgia ADU on many projects over the past 10 years as well as recommending them to a few friends. The renovations have gone extremely well and their communication has been top notch along the way. It is always tough to determine the right mix between quality and price and they have always done a great job at providing high quality at a great price. I can very highly vouch for their experience, professionalism and caring attitude."
