Summary
Guilford County lets LED message boards run on permanent signs in every non-residential district, but UDO Subsec. 7.9.B caps display area at 70-75% of the allowed sign face, sets minimum message hold times of 8 or 12 seconds, and restricts operating hours by district. Portable trailer-mounted units need a Temporary Event/Use Permit, are capped at 32 square feet and 5 feet tall, and may run for only 30 days per permit.
B. ELECTRONIC CHANGEABLE COPY SIGNS (LED MESSAGE BOARDS) STANDARDS 1. In general, LED message boards are allowed in Guilford County provided they meet the standards of this subsection... 3.

The size of the message board does not exceed thirty-two (32) square feet, excluding towing apparatus. b. Maximum height, including towing apparatus, does not exceed 5 feet. c. The sign is not placed within any sight triangle, public right-of-way, or vacant lot. ... e. The sign shall be displayed no more than thirty (30) calendar days from the date the permit is issued. f. No more than four (4) permits may be issued for a portable LED message board for any address.
Full Breakdown
UDO Subsec. B governs LED message boards countywide. 2: 70% in the county's residential and agricultural districts (AG, RS-40 through RS-7, RM-26, RM-18, RM-8) and in office/institutional districts (PI, CP, LO, NB), rising to 75% in the LI and HI industrial districts. Minimum message duration is 12 seconds in residential and office districts and drops to 8 seconds in LB, MXU, GB, HB, LI and HI. Operating hours track the same split: 7:00 AM-9:00 PM in residential/agricultural zones, 6:00 AM-10:00 PM in office/institutional zones, and 5:30 AM-midnight in the commercial and industrial districts.
Messages must be static; the code bars animated features during and between message transitions, and every board must carry a photo sensor that dims brightness for daylight conditions. Portable, trailer-mounted LED boards are handled separately: they require a Temporary Event/Use Permit, cannot exceed 32 square feet of message area (towing apparatus excluded) or 5 feet of height including the trailer, cannot sit in a sight triangle, public right-of-way or vacant lot, and can be displayed for no more than 30 calendar days per permit. The county caps portable boards at four permits per address, which stops an owner from simply re-permitting the same trailer sign back-to-back for a permanent digital display. Permits are issued and enforced through the Planning & Development Department under Subsec. 3 (Permits and Procedures).
Violations & Fines
Operating an LED message board that exceeds the district's area, duration or hours limits, or running a portable board without a Temporary Event/Use Permit, is a UDO sign violation enforced by the Planning & Development Director. Staff can order the board removed or the permit revoked, and continued noncompliance is prosecuted as a code violation under the county's general penalty provisions, which can include a misdemeanor citation and daily civil penalties until the sign is brought into compliance.
