Homeowners’ Guide to Navigating Nashville’s DADU Regulations

As Nashville continues to grow, Detached Accessory Dwelling Units (DADUs) have emerged as a smart way for homeowners to add living space, rental income, or flexible family housing without sacrificing their primary residence’s character. A DADU is a standalone, self-contained living space on the same lot as a single-family home, complete with sleeping, kitchen, bath, and living areas. Navigating the city’s DADU regulations can feel complex, but with the right partner, it doesn’t have to be. Deed Brothers helps Nashville homeowners conceptualize and build DADUs tailored to their lot and goals, navigating the complexities from design through completion.

Where Can You Build a DADU in Nashville?

Not every property in Nashville is automatically eligible for a DADU. The DADU overlay is a zoning mechanism that designates where Detached Accessory Dwelling Units are permitted, modifying base zoning to allow these secondary structures. Some Nashville neighborhoods require that the DADU meet additional criteria, like being located on an alley or having a sufficient lot size. These rules exist to preserve neighborhood character while enabling thoughtful infill. 

Deed Brothers’ experience with Nashville zoning realities means we can pre-screen your lot, determine overlay eligibility, and advise on whether variances or supplemental approvals are needed, saving you time and reducing the risk of costly redesigns.

Overlays, Historic Constraints, and Covenants

To build a DADU in Nashville, the parcel must have only one primary single-family dwelling; parcels already containing two single-family homes are not eligible. Even when basic zoning aligns, overlays (particularly the DADU overlay or historic overlay) play a crucial role. Properties in certain historic overlay districts must comply with extra steps, such as recording a Restrictive Covenant that confirms the DADU is accessory to the principal structure and adheres to size, height, and design subordinate requirements. These extra steps are intended to ensure compatibility with historic context while still enabling accessory living space. 

Deed Brothers coordinates these nuanced requirements with ease. We handle covenant documentation, engage preservation or planning staff when needed, and align the DADU design so it meets both historic sensitivity and current code expectations.

Permitting and Code Compliance for DADUs

Once you confirm eligibility, the next step is meeting the physical and design constraints. You’ll need to secure the appropriate permits through Metro Nashville’s Codes Department. Nashville’s zoning code limits accessory building coverage, and setbacks (typically a minimum of five feet from side and rear property lines) must be respected. DADUs must be subordinate in size and height to the primary residence, and there are coverage caps based on lot size and principal dwelling footprint. Understanding these controls upfront avoids costly revisions during design or permitting.

Deed Brothers manages the permit package preparation, submits applications, and interfaces with inspectors and reviewers so homeowners don’t get stuck in bureaucratic delays. Our familiarity with Nashville’s permitting workflows helps accelerate approvals while keeping your project code-compliant.

Step-By-Step Process to Build Your DADU in Nashville

Building a DADU involves a sequence of deliberate steps: 

  • Research Zoning and Confirm Eligibility: Start with confirming your lot’s zoning status, overlay inclusion, and whether any special conditions apply. 
  • Survey Property Lines and  Setbacks: Accurate measurements establish what footprint you can legally build.
  • Historic or Covenant Review: If applicable, record required covenants and address preservation standards. 
  • Design the DADU: Collaborate on a plan that balances function, compliance, and visual harmony with the main house. 
  • Submit Application and Obtain Permits: Submit for building, electrical, plumbing, and any preservation permits; expect review timelines and plan for possible administrative back-and-forth. 
  • Construction and Inspection: Build under code, scheduling required inspections at key phases to secure eventual occupancy approval.

Throughout each phase, Deed Brothers provides strategic guidance, design iteration, and hands-on construction execution based on Nashville’s evolving regulatory landscape.
