Chattanooga treats political signs as exempt yard signs needing no permit. They may be up to 32 square feet and 10 feet tall, but all political yard signs must be removed within 15 days after the election they refer to.
Under Chattanooga's rewritten sign code (Chapter 3B, adopted April 2025), yard signs "including but not limited to garage sale, temporary signs for political, construction or real estate purposes" are exempt from a sign permit. Political signs are further excluded from the general 15-days-before/30-days-after time cap that binds other yard signs, but Sec. 3-146(3)(e) requires that "all such political yard signs shall be removed within fifteen (15) days after the election to which they refer has been held." Primary-election signs may remain only if still valid for the next general election. Yard signs are capped at 32 square feet in area and 10 feet in height, and cannot be attached to trees, utility poles, fences, or placed in the public right-of-way.
Signs left past the 15-day post-election window, oversized, or placed on poles or right-of-way may be ordered removed or relocated by the Building Official or Chattanooga Department of Transportation.
