Chattbuilt: ADU Contractors Serving Chattanooga
Chattbuilt is a Chattanooga-based ADU contractor specializing in the design, planning, and construction of accessory dwelling units. Building an ADU is a significant investment, and navigating local zoning laws, permitting requirements, and construction logistics can be a complex process. Chattbuilt's project management team works to guide property owners through each stage, from initial planning to final inspection.
Their team handles design, permit acquisition, and construction, staying current with Chattanooga's zoning and permitting requirements to help keep projects compliant and on schedule. Each ADU project is treated as unique, with attention given to the specific goals and requirements of the property owner.
What Is an ADU and What Are the Local Rules?
An accessory dwelling unit (ADU) is a secondary residential structure located on the same lot as a primary single-family home. In Chattanooga, ADUs are permitted in all areas zoned for single-family detached dwellings (R-1 zoning). Multi-family properties such as townhouses and apartments are currently not eligible to add ADUs.
Key regulations to be aware of include:
- ADUs cannot exceed 700 square feet of conditioned living space.
- ADUs must be at least 200 square feet and built on a permanent foundation — they cannot be constructed on wheels.
- The ADU must be owned by the same property owner as the primary dwelling and cannot be subdivided or sold separately as a fee simple condo.
- If existing on-site parking is affected during construction — such as in a garage conversion — it must be replaced or maintained.
- ADUs are permitted in Chattanooga's historic districts, including Fort Wood, St. Elmo, Battery Place, and Ferger Place, but must receive approval from the Chattanooga Historic Commission as part of the plan review process.
ADUs can be built on rental properties, not just owner-occupied homes. However, property owners should check with any applicable Homeowner Association (HOA) for restrictions that may apply.
Regarding short-term rentals, the City of Chattanooga allows ADUs to be rented for up to 30 days without a permit. Properties within the city's short-term rental boundary may apply for permits for vacation rental use, though the City Council has imposed a moratorium on new permits for non-owner-occupied vacation rental properties.
