Nashville's Zoning Overlays & Bonuses: The Rules That Matter

Every city handles zoning overlays & bonuses a little differently. In Nashville, Tennessee, there are 2 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Density Bonus Law

Metro Nashville grants developers up to a 25% density or floor-area bonus in a Planned Unit Development in exchange for dedicating land for public use, such as parks, schools, or greenways.

Key details: Bonus amount: 25% density or FAR increase. Trigger: Public land dedication in a PUD. Approving body: Metro Council. Applies to: PUD master development plans only.

There's no fine for skipping the bonus: it's optional. A PUD master development plan that claims a density bonus without a qualifying public dedication (or that exceeds the 25% cap per dedication type) will be rejected by the Metro Planning Commission and Council at plan approval, and any construction based on an unapproved plan can be halted by the Codes Department for lacking a valid zoning permit.

Downtown Design Guide

Metro Nashville adopted the Downtown Code (DTC), a separate development-standards document that sets building placement, height, and design rules for the DTC zoning district and overrides the citywide bulk-regulation tables in Chapter 17.12.

Key details: Governing chapter: Metro Code Chapter 17.37 (DTC). Latest adopting ordinance: Ord. BL2025-799 (2025). Applies to: Property zoned DTC downtown. Supersedes: General bulk table § 17.12.020. Full document held by: Metro Planning Department.

The zoning administrator enforces Title 17 citywide, including the DTC, and can refuse to issue a zoning permit or certificate of compliance for construction that doesn't meet the adopted DTC standards (Metro Code § 17.40.010).

The Bottom Line

Nashville's zoning overlays & bonuses rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Nashville is broadly strict or permissive.

Keep in mind that Nashville can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
