Summary
Alameda's sign code bans flashing lights, changing color intensity, and mechanical movement on any sign, a prohibition broad enough to cover digital and electronic billboards, under Municipal Code Section 30-6.9.e. The only way around it is a use permit finding that an animated sign has outstanding artistic merit; historic signs and barber poles are separately exempted.
e.Motion Devices. Signs utilizing flashing lights, changing of color intensity, or mechanical moving parts are prohibited including all moving signs. (Exceptions: historic signs, barber poles and, with a use permit, animated signs but only if determined by the use permit to have outstanding artistic merit.)

Full Breakdown
9, 'Prohibited Signs,' lists motion devices among the sign types banned outright in Alameda: signs utilizing flashing lights, changing of color intensity, or mechanical moving parts are prohibited including all moving signs. Because a digital or electronic billboard display works by changing color intensity and imagery, it falls squarely within this prohibition rather than the code's ordinary permitting track for permanent signs. The subsection carves out only three exceptions: historic signs, barber poles, and, with a use permit, animated signs but only if determined by the use permit to have outstanding artistic merit.
3, meaning the Planning Board must make an affirmative artistic-merit finding before any changing-image sign can be approved; a routine commercial digital display advertising rotating messages does not qualify. 13: they cannot be located in residential or C-1 districts, cannot exceed fifty square feet, and must keep at least 100 to 1,000 feet of separation from other off-premises signs depending on their size, further narrowing where any billboard, digital or static, could legally stand even before the motion-device ban is applied.
Violations & Fines
Motion-device signs are treated as an immediately-abatable prohibited sign class under Section 30-6.10.b: violators get thirty days to remove them once notified. If the owner fails to comply, the Planning and Building Director may remove the sign and supporting structure and bill the cost to the permittee, sign owner, property owner, or occupant, who are jointly and severally liable under Section 30-6.11.a.
