Building Setbacks & Zoning in Franklin, TN

Franklin maintains 127 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 Franklin falls on the strict-to-permissive spectrum compared to other cities.

Structure Height Limits

In Franklin's R1 (Residential 1) zoning district, a principal house is capped at 2 1/2 stories under the 2026 Franklin Zoning Ordinance. Accessory structures can't exceed the height of the principal building on the same lot, and minor accessory structures are capped at one story.

Key details: Principal building height cap: 2 1/2 stories. Accessory structure height cap: capped at principal building height. Minor accessory structure cap: 1 story. Minimum lot size: 30,000 square feet. Front/side/rear setbacks: 60 ft / 25 ft / 50 ft.

Franklin's Building and Neighborhood Services Department reviews building permit applications against the Section 3.4.5 dimensional table before issuing a permit; a plan set showing a principal building over 2 1/2 stories, or an accessory structure taller than the house it serves, is rejected at plan review rather than caught after construction. A structure built over height without a recorded-plat override on file is a zoning-ordinance violation subject to the city's standard zoning enforcement and stop-work process.

Lot Coverage Limits

In Franklin's Downtown District (DD), buildings can cover up to 85 percent of a lot: the Zoning Ordinance's dimensional standards table sets building coverage at a maximum of 85% and drops the minimum landscape surface area requirement to zero, reflecting the district's compact, pedestrian-oriented downtown core rather than a conventional suburban open-space standard.

Key details: Max building coverage (DD district): 85% of net lot area. Min landscape surface area (DD district): 0% (no minimum). Governing section: Zoning Ordinance § 3.15.5, eff. Jan. 13, 2026. Appeal path: BZA variance under § 20.10. Penalty: Misdemeanor, Title 12 general penalty, § 22.5.

Exceeding the DD district's 85% building-coverage cap without an approved variance is a misdemeanor under Zoning Ordinance § 22.5, fined under Title 12 of the Municipal Code's general penalty clauses, with each day of noncompliance a separate offense. The City Attorney or a damaged neighboring property owner may also seek an injunction or mandamus action under § 22.6 to force compliance, including against work already underway.

Setback Rules

Franklin's R1--Residential 1 District requires a 60-foot front, 25-foot side, and 50-foot rear setback for principal buildings under the 2026 zoning ordinance.

Key details: District: R1--Residential 1. Front setback: 60 feet minimum. Side setback: 25 feet minimum. Rear setback: 50 feet minimum.

Building without meeting the required setback, or exceeding the permitted appurtenance encroachment, is a zoning violation subject to a stop-work order or denial of a certificate of occupancy from Franklin's Building and Neighborhood Services Department; a variance from the Board of Zoning Appeals is required to build closer than the standard allows.

The Bottom Line

Franklin'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 Franklin is broadly strict or permissive.

These rules come from Franklin's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
