Summary
Alachua County bans electronic message centers on freestanding signs along the Interstate 75 corridor entirely. Elsewhere, a permanent freestanding sign's electronic display is capped at 20 percent of the sign face or ten square feet, whichever is smaller, must use a dark background with non-flashing monochromatic lettering, and can change no more than once every five minutes.
Permanent freestanding signs, except those located along the Interstate 75 corridor, may contain internally illuminated electronic message centers, subject to the following standards:a.The electronic message center shall occupy no more than twenty (20) percent of a sign's total square footage or ten (10) square feet, whichever is less.b.The electronic message center shall consist of a dark background, with monochromatic lettering that does not flash or move.c.The message displayed in an electronic message center shall not change more than once in a five-minute period.

Full Breakdown
31(d)(2) of the ULDC governs electronic message centers on permanent freestanding signs in nonresidential developments. Outside the Interstate 75 corridor, where they are prohibited outright, a freestanding sign may carry an internally illuminated electronic message center only if the display occupies no more than 20 percent of the sign's total square footage or ten square feet, whichever is less. The display must use a dark background with monochromatic lettering, and that lettering cannot flash or move. The message itself is capped at one change per five-minute period.
28(a)(4) bans 'changeable copy signs on which the message changes more than one (1) time in a five-minute period that are legible from a public way or private property other than the site on which the sign is located,' making the five-minute change limit an outright prohibition, not just a design guideline, for any changeable-copy sign visible from a road or neighboring lot. 28(a)(2) separately bans animated signs and (a)(5) bans flashing signs countywide, reinforcing the static-display requirement. 31(a)(1); a single-tenant site is generally allowed one freestanding sign up to 50 square feet and ten feet tall, so the message center itself is a small carve-out within that footprint. These rules apply only to unincorporated Alachua County; Gainesville and the county's other municipalities regulate digital signage separately.
Violations & Fines
An electronic message center exceeding the 20 percent/ten-square-foot cap, using flashing or moving lettering, changing its message more than once every five minutes, or installed on a freestanding sign along the Interstate 75 corridor violates Sections 407.31(d)(2) and 407.28(a)(4). Growth Management can deny or revoke the sign permit, and a code officer may issue a citation under Section 24.14 carrying a civil penalty of up to $500 per infraction.
