The Short Answer
Like-for-like window replacement in the same opening is exempt from permitting in Tullahoma. Historic-district homes and any opening enlargement require a permit.
Tullahoma enforces Tennessee building code adoption with a critical local wrinkle: the city maintains a historic-district overlay (the downtown core and surrounding neighborhoods qualify) where window styles, materials, and profiles must match the existing character BEFORE you pull a permit. This pre-approval step is unique to Tullahoma's historic preservation rules — the surrounding county and neighboring cities like Manchester do not have the same overlay restrictions. If your home is outside the historic district and you are replacing windows in the same opening with the same operable type (casement for casement, double-hung for double-hung), you do not need a city permit. However, if you are enlarging any opening, changing sill height above 44 inches in a bedroom (which violates IRC R310 egress requirements), or working in the historic district, a permit is required and you must file design-review documentation with the Planning Department before construction.

What happens if you skip the permit (and you needed one)

Tullahoma window replacement permits — the key details

Tennessee Building Code (most recent cycle adoption in Tullahoma is 2020 IBC/IRC with some amendments) exempts like-for-like window replacement in existing openings from permitting. The operative rule is IRC R612 (fall protection for windows) and IRC R310 (emergency escape and rescue openings). If your replacement window is the exact same size, material type (vinyl, wood, aluminum), and operable function (double-hung, casement, fixed), and the sill height does not exceed 44 inches in a bedroom or bathroom, you are exempt. This exemption applies throughout Tullahoma city limits, unincorporated Coffee County, and neighboring jurisdictions. However, Tullahoma's downtown historic district (roughly bounded by Jackson Street, Grundy Street, and the railroad corridor) has a LOCAL OVERLAY ORDINANCE that requires design-review approval BEFORE you purchase or install ANY replacement window, even if it is the exact same size. This is not a permit per se — it is a pre-permit design-review submission to the Planning Department. The city's historic-district guidelines specify that replacement windows must match the profile, muntins (grid pattern), and material (wood is preferred; vinyl is allowed only if it mimics wood profiles) of the existing historic window. Many homeowners in the historic district are surprised by this requirement because the neighboring city of Manchester and the unincorporated county do not enforce it.
