Building Setbacks & Zoning in Nashville, TN

Nashville maintains 167 local ordinances across all categories, and 3 of those deal specifically with building setbacks & zoning. Here is a breakdown of what the city actually requires, what is prohibited, and where Nashville falls on the strict-to-permissive spectrum compared to other cities.

Structure Height Limits

Metro Nashville caps most single-family and two-family homes at 24 feet to the eave and 35 feet to the roof ridge, with flat 3-story caps in large-lot districts and inside the I-40/I-65 loop.

Key details: Standard cap: 24 ft eave, 35 ft ridge. Large-lot districts: flat 3-story cap. Downtown loop area: 3 stories / 45 ft max. Height measured from: average grade plane, post-development. Enforced by: Metro zoning administrator.

Metro Codes Department enforces height limits through building permit plan review; construction exceeding the eave/ridge or story cap can be denied a permit, red-tagged, or ordered to remove the non-compliant portion.

Setback Rules

Rear and side yard setbacks for single- and two-family homes in Metro Nashville run from 20 feet in the largest AG and RS80 zones down to 3 feet in the densest RS3.75 zone, per the Metro Zoning Code's District Bulk Table 17.12.020A.

Key details: AG, RS80 zones (largest lots): 20 ft rear, 20 ft side. RS10, R10 zones: 20 ft rear, 5 ft side. RS3.75 zone (smallest lots): 20 ft rear, 3 ft side. Front/street setback: Set separately, Table 17.12.030A. Satellite cities excluded: Belle Meade, Berry Hill, 4 others.

Building without the required rear or side setback is a zoning code violation; Metro Codes can issue a stop-work order and require the encroaching structure to be moved or removed at the owner's expense.

Lot Coverage Limits

Metro Nashville caps how much of a single-family or two-family lot a house can cover, from 20% in the largest-lot AG and RS80 districts up to 60% in RS3.75 and higher-density zones.

Key details: AG, RS80/R80 districts: 20% max building coverage. RS3.75 and higher-density districts: 60% max building coverage. Multifamily/nonresidential cap: 0.60–0.80 max impervious surface ratio. Hillside slopes 25%+: effective ISR drops to zero. Coverage violation penalty: $500 per day, misdemeanor.

Building without a zoning compliance permit or exceeding the coverage cap is a misdemeanor plus a $500-per-day civil penalty, and Metro can triple permit fees for work started without one (Metropolitan Code of Laws §§ 17.40.610, 17.40.620).

The Bottom Line

Nashville's building setbacks & zoning 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.
