Hamilton County, TN Sign Regulations: Digital Billboards (2026)

Article V, § 203(I) (Motorist Safety) governs off-premise billboards and provides that no sign shall have moving parts, picture tubes, lights or illumination that vary in intensity, flash or change, except that tri-vision off-premise signs with moving parts shall be permitted. The Regulations define a tri-vision sign, at the sign-definitions section preceding § 202, as an on-premise or off-premise sign with movable panels and/or lights, meaning a mechanical rotating-panel billboard is allowed while a true electronic, LED, or video message board that changes its display is not.

The same subsection also bars signs near confluences of traffic or interstate entrance and exit ramps if they would be visually obstructive, and separately prohibits any sign that resembles a regulatory or warning traffic control device listed in the Manual on Uniform Traffic Control Devices. An off-premise sign permit is required before installation under § 203(A), issued by the Hamilton County Building Inspection Department, and any permitted sign not completed within six months has its permit revoked. Off-premise signs are only allowed at all in the C-1, C-2, C-3, M-1, M-2, M-3 and M-4 districts under § 203(A), so a proposed digital billboard is doubly restricted: it must sit in one of those districts and, even there, cannot use changing electronic illumination.
