DADU Nashville: Sample Garage Conversion to a Detached Accessory Dwelling Unit

As housing demand continues to grow in Nashville, many homeowners are exploring flexible ways to add living space to their properties. One of the most effective solutions is a Detached Accessory Dwelling Unit (DADU).

This sample project demonstrates a garage-to-DADU conversion in Nashville, showing how an existing detached structure can be transformed into a fully functional secondary residence. The project also illustrates the type of architectural drawing set typically required for permits and construction.

What Is a DADU?

A DADU, or Detached Accessory Dwelling Unit, is a small and independent residential structure located on the same property as a primary home. Unlike an attached addition, a DADU is physically separated from the main house, functioning as a self-contained living unit with its own entrance and essential residential spaces.

In Nashville, DADUs have become increasingly popular as homeowners look for flexible ways to expand the use of their properties. These units can serve a variety of purposes, such as providing comfortable accommodations for guests, creating long-term rental opportunities, or offering dedicated spaces for home offices and studios. In many cases, DADUs also support multigenerational living by allowing family members to live nearby while maintaining privacy and independence.

Depending on local zoning regulations, some DADUs may also be used for short-term rentals, which can create additional income potential for homeowners. Beyond their functional benefits, a thoughtfully designed DADU in Nashville can significantly increase property value while making better use of underutilized backyard areas or existing structures such as detached garages.

Garage Conversion to DADU

One of the most efficient ways to create a DADU is by converting an existing detached garage. Reusing an existing structure allows homeowners to transform underutilized space into a functional residential unit while maintaining much of the original building footprint.

In this sample project, the garage is redesigned into a compact and comfortable living space. The design introduces new windows to improve natural light, organizes the interior into an efficient floor plan, and incorporates elements such as a vaulted ceiling to enhance spatial quality. The result is a fully independent dwelling unit that integrates naturally with the property while meeting local Nashville zoning and building requirements.

What Is Included in a Typical DADU Drawing Set?

For permitting and construction, a complete architectural drawing set is required. Our DADU projects in Nashville typically include the following documentation.

Site Plan

A site plan shows the relationship between the existing house, the DADU structure, property boundaries, and access points. It also identifies setbacks, drainage considerations, and existing structures.

Floor Plans

Floor plans illustrate the layout of all interior spaces, including walls, doors, windows, fixtures, and dimensions.

Roof Plan

The roof plan defines the roof geometry, slopes, ridges, drainage directions, and materials used in the project.

Exterior Elevations

Exterior elevations describe the appearance of the building from all sides, including building height, roof pitch, exterior materials, and window and door placement. These drawings are essential for permit review and ensuring the DADU fits the neighborhood context.

Window & Door Schedule

A window and door schedule provides detailed information about the size, type, and specifications of each window and door used in the project, helping ensure accurate coordination during construction.

Cabinetry Elevations

Cabinet drawings detail kitchen storage layouts, shelving, and appliance integration, ensuring the construction team builds the interior correctly.

Electrical Plans

Electrical plans indicate the location of lighting fixtures, switches, outlets, and appliances, which are required for construction and inspections.

3D Views

3D visualizations help homeowners understand how the finished DADU will look and feel before construction begins.

Designing a DADU: Our Approach

Our architectural approach to DADU projects focuses on balancing functionality, spatial quality, and regulatory requirements. Each project begins with an understanding of local zoning and building regulations, followed by a design process that prioritizes efficient use of space, natural light, and compatibility with the existing home. Whether the project involves a garage conversion, a new detached structure, or a backyard studio, the goal is to create a well-designed and comfortable living environment supported by a clear and comprehensive architectural drawing set.
