Summary
Hayward treats digital signage as an "electronic reader board," not a freestanding billboard, and reserves it for religious facilities, private schools and cultural facilities under zoning approval. Municipal Code Sec. 10-7.501(b) caps message changes at once every six seconds, bans flashing or traveling text, and sets candela brightness ceilings by color that shrink at night. A sign permit is mandatory before installation.
Electronic reader boards are permitted for religious facilities, private schools, and cultural facilities as allowed by zoning district and in conformance to the provisions of this article or as determined by the Development Services Director. ... The copy on an electronic reader board sign shall not change more than once in a six-second period unless otherwise allowed by law or except as necessary on a sign for the public health and safety, including traffic control, that is owned and/or operated by the city, Alameda County, State of California, or federal government. ... Electronic reader boards must meet the following requirements:i.Static display time for each message is a minimum of six seconds;ii.The time to completely change from one message to the next is a maximum of two seconds;iii.The change of message shall occur simultaneously for the entire sign face;iv.The sign shall contain a default design that will hold the face of the sign one position if a malfunction occurs;v.No flashing lights, traveling messages, animation or other movements are permitted on an electronic reader board;

Full Breakdown
Hayward's sign code splits digital displays into two tracks. Under Sec. 400(5), "Changeable Copy Signs/Electronic Reader Boards" are prohibited citywide except for facilities used for theatrical, cultural, church, school, sports or seasonal events, or industrial uses with freeway frontage as allowed by zoning district. Sec. 501(b) then sets the operating rules for those permitted boards: religious facilities, private schools and cultural facilities may install one with zoning approval, and installation or replacement of an existing sign with a reader board requires a sign permit through Development Services.
Each message must hold for a minimum of six seconds, the transition to the next message cannot take longer than two seconds, and the change must happen simultaneously across the whole sign face. Every board needs a default design that freezes the display in one position if it malfunctions, and no flashing lights, traveling messages or animation are allowed. Illumination is capped by color: red tops out at 300 candelas per square foot by day and 100 at night, green at 600/200, amber at 450/150, blue at 800/350, and multi-color displays at 650/250, measured at any point on the roadway or driveway approach.
Boards that move continuously, flash, pulse or change color outside these limits are reclassified as animated signs and banned outright under Sec. 501(b)(1)(c)(vii). Freeway-oriented commercial centers of five acres or more with an approved Master Sign Program get a separate carve-out for reader boards under Sec. 502(b), and theater marquees may show movie times on a reader board under Sec. 502(c).
Violations & Fines
An electronic reader board installed outside the eligible uses, or one that flashes, animates or exceeds the brightness table, is a prohibited sign under Sec. 10-7.400(5) and (7). The Development Services Director can remove or order removal of an illegal sign under Sec. 10-7.711, following the abatement procedure in Chapter 5, Article 7 (Community Preservation and Improvement). Sec. 10-7.714 makes a violation an infraction or a misdemeanor under Chapter 1, Article 3 of the Municipal Code, and each unresolved violation can trigger a separate enforcement action.
