Downtown Franklin · Franklin, TN
Additions and remodels inside Franklin's historic core
Downtown Franklin is one of the largest and best-preserved collections of historic architecture in Middle Tennessee — a 15-block National Register commercial core ringed by Victorian, Colonial Revival, bungalow, and Tudor Revival neighborhoods. Most of it sits inside the Historic Preservation Overlay, so exterior work runs through the Historic Zoning Commission before a building permit is issued.
History & architecture
How Downtown Franklin was built
Franklin was founded October 26, 1799 and named for Benjamin Franklin by Dr. Hugh Williamson, a member of the Continental Congress. For most of its first 180 years it was a county seat surrounded by farmland, and before the Civil War Williamson County was one of the wealthiest counties in Tennessee.
The Battle of Franklin on November 30, 1864 was one of the war's bloodiest, with more than 8,000 casualties, and nearly every building in town became a hospital. Recovery was fast in town but slow county-wide — the local economy did not reach pre-war levels for roughly 120 years.
By 1871 the town held 66 businesses, and the 1880s and 1890s filled the Public Square and Main Street with one- and two-story brick commercial buildings. Residential growth pushed south into Hincheyville and out along Lewisburg Avenue.
Between 1900 and 1940, Colonial Revival, Bungalow, and Tudor Revival houses filled in those same areas on small lots, producing the dense, compact streetscape around the Square that still defines downtown today.
The Heritage Foundation formed in 1968 in response to suburban development pressure, the 15-block downtown was listed on the National Register, and Main Street revitalization followed — the reason downtown reads as a preserved place rather than a rebuilt one.

Zoning & overlays
Common zoning codes in Downtown Franklin
These are the base districts and overlays we see most often on Downtown Franklin lots. Always confirm your parcel's district and overlays on the Metro zoning map before design decisions get expensive.
R4Residential 4 District
The contextual district behind much of Central Franklin. Lot size and width are set at 75% of the block-face average (never below 6,500 sq ft / 60 ft), front setback matches the block face, side 7 ft, rear 20 ft. Height is capped at a half story above the block-face average, maximum 2 1/2 stories.
R6Residential 6 District
The tightest historic blocks: 4,000 sq ft minimum lot, 40 ft width, 5 ft side and 15 ft rear setbacks, and street-facing height capped at 2 stories. No appurtenance encroachments into side or rear setbacks.
R2 / R3Residential 2 and 3 Districts
Found on the larger-lot edges of the downtown neighborhoods — 15,000 and 9,000 sq ft minimums with fixed 20 ft front setbacks rather than block-face averaging.
Overlays that apply here
HPO
Historic Preservation Overlay
Franklin's local designation. Seven locally designated historic districts range from the five-parcel Everbright Avenue district to the Franklin Road district, which runs nearly two miles north of downtown. HPO is where the COA requirement bites.
National Register
Franklin, Hincheyville, Lewisburg Avenue, Adams Street, Natchez Street districts
Five National Register districts covering more than 1,060 buildings. National Register listing is honorific — it does not restrict private exterior work on its own.
NCO
Neighborhood Conservation Overlay
Block-level overlays with their own adopted standards for scale, setbacks, and materials, used where full historic designation is not in place.
Permitting path
- 1Check whether the parcel sits inside Franklin's Historic Preservation Overlay (HPO) on the city's historic districts map — National Register listing alone carries no restrictions, but local HPO designation does.
- 2Inside the HPO, a Certificate of Appropriateness (COA) is required before new construction, additions, porches and decks, window or siding changes, roofing changes, dormers, fences and driveways, and any demolition or relocation.
- 3Minor, guideline-compliant work can be issued as an Administrative COA by the Preservation Planner; larger work goes to the Historic Zoning Commission, which meets monthly.
- 4Preservation staff encourage a preliminary meeting, and the Design Review Committee gives informal feedback from HZC members before a formal application — worth using on any addition.
- 5Reviews are measured against the Franklin Historic District Design Guidelines (effective May 30, 2022), with the Secretary of the Interior's Standards applied where relevant.
- 6Outside the HPO, there is no design review layer — the base district's setbacks, height, and landscape surface area requirements govern, plus any HOA architectural review.
Why it matters
Downtown Franklin's place in Franklin
Downtown Franklin is the civic and commercial heart of Williamson County and the reason the city reads as a historic place rather than a suburb — its preservation record is the model other Middle Tennessee towns cite.
It carries the region's heaviest design scrutiny. Additions here are judged against the block face, not just the zoning table, which is exactly why an early conversation with preservation staff saves months.
Teardown pressure is real even inside the historic residential areas, and Envision Franklin explicitly encourages rehabilitation over demolition — thoughtfully designed additions are the path of least resistance.

What this means for your Downtown Franklin project
- Put new mass at the rear. Franklin's guidelines favor additions that are subordinate to the historic house and read clearly as later work from the street.
- In R4 and R6, the block face sets your numbers — front setback, lot width, and allowed height all key off neighboring buildings, so document the block before sizing anything.
- Windows and siding are review triggers on their own. Replacement is a COA item, so specify materials and profiles in the drawing set rather than leaving them to the builder.
- Site elements count too: fences, walls, driveways, walkways, lighting, and even mechanical equipment placement are reviewed inside the HPO.
- Budget for the calendar. HZC meets monthly and Codes will not issue a permit without the COA, so a preliminary meeting plus a Design Review Committee session up front usually shortens the total timeline.
