About Georgia ADU Builder

What Is an ADU and What Does Georgia ADU Builder Offer?

An Accessory Dwelling Unit (ADU) is a self-contained living space located on the same property as a single-family home. These units typically include a bathroom, kitchenette, and sleeping area, making them suitable for full habitation. Common uses include in-law suites, rental units, and housing for family members. Georgia ADU Builder specializes in designing and constructing these structures across Cobb, Fulton, Forsyth, Gwinnett, Cherokee, Bartow, and DeKalb Counties.

In addition to traditional ADUs, Georgia ADU Builder also offers Backyard Getaways — functional spaces that extend the usable area of a home without requiring full habitation amenities. These can serve as home offices, yoga studios, gyms, libraries, smoking lounges, wine tasting rooms, or potting sheds. The range of possibilities is broad, and designs are tailored to each client's specific property and preferences.

As an experienced ADU contractor and backyard cottage builder, Georgia ADU Builder works with homeowners to develop designs that suit both the physical constraints of the property and the lifestyle goals of the owner. Whether the project calls for a detached ADU, a granny flat, or a custom backyard structure, their team approaches each build individually rather than applying a one-size-fits-all solution.

Design, Construction, and Cost Considerations

Georgia ADU Builder takes a custom design approach. Rather than offering pre-existing floor plans or modular kits, they work with clients from the ground up. This method has proven to be both practical and cost-competitive, as adapting pre-existing plans to unique properties often creates complications that a tailored design avoids from the start.

A completed example of their work includes a 2-bedroom, 2-bathroom unit within 794 square feet — demonstrating that well-planned smaller spaces can deliver a quality living experience. Their design philosophy centers on what they describe as affordable luxury: delivering functional, well-finished spaces without requiring an outsized budget.

The primary cost components involved in building an ADU include:

  1. Planning and Permitting: This includes conceptual design, architectural blueprints, and a multi-phase site survey. These steps are necessary to ensure the project meets local regulations before construction begins.
  2. Site Preparation: Clearing and grading the land varies in cost depending on soil conditions, topography, and existing structures on the property.
  3. Construction: This phase covers foundation work, framing, exterior finishes (siding, roofing, windows, doors), mechanical systems (plumbing, electrical, HVAC), interior finishes, and final trim and fixtures.

Georgia ADU Builder provides transparent cost estimates and works with clients to develop a budget aligned with their goals. The construction phase itself tends to move relatively quickly — typically spanning a few months from groundbreaking to completion. The planning and permitting phase, however, can take longer depending on third-party schedules and specific property conditions.

Factors that may extend the permitting timeline include:

  1. Properties located in flood plains or environmental impact zones
  2. Historic district designations requiring additional approvals
  3. Properties on septic systems rather than municipal sewer, which often involves health department review

To help manage these variables, Georgia ADU Builder has expeditors on staff who work to streamline the permitting process as much as possible.

Practical Uses for ADUs and Backyard Spaces

The demand for additional on-property space has grown alongside trends in remote work and home-based activities. Many homeowners are choosing to add a detached ADU or backyard structure to serve as a dedicated home office — physically separated from the main living areas to support focus and productivity. Others are investing in climate-controlled garden spaces, guest accommodations, or short-term rental units.

For those looking at the rental market, a well-designed accessory dwelling unit can function as a Casita or guest house, offering a private, self-contained space for visitors or tenants. These units can also serve as long-term housing for aging parents or adult children, functioning effectively as an in-law suite or granny flat.

Georgia ADU Builder works across a range of architectural styles — from modern farmhouse and craftsman to contemporary and retro aesthetics — adapting each design to complement the existing home and the homeowner's vision. The goal is to create a space that adds both practical value and long-term property value.

"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."

"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."
