Full Breakdown

700(6) prohibits animated signs that use blinking lights, audible sounds, or human- or animal-generated movements, but the same subsection carves out an exception: this restriction does not apply to electronic message signs and time and temperature signs. That carve-out does not make digital billboards unregulated, though. 302(12) separately prohibits changeable copy signs, the broader category that covers electronic message displays capable of switching messages, except as approved through a master sign program. 400, the same review track used for large multi-tenant centers and site-wide signage plans. 103.

Violations & Fines

Installing a changeable copy or electronic message sign without an approved master sign program is a sign code violation. Section 13-34.205 lets the Chief Building Official order removal within 30 days of written notice, and Section 13-34.207 authorizes the Planning Commission or City Council to revoke a sign permit and empowers the City Attorney to prosecute the sign as a public nuisance if it is not removed.

Frequently Asked Questions

Are digital billboards legal in Hercules?
Only through a master sign program. Section 13-34.302(12) prohibits changeable copy signs, the category covering electronic message displays, unless the City has approved them as part of a master sign program for the site.
Doesn't the City ban all animated or blinking signs?
It bans animated signs using blinking lights, audible sounds, or simulated movement under Section 13-34.700(6), but that same subsection expressly excludes electronic message signs and time-and-temperature signs from the animation ban.
Who reviews a proposed digital sign in Hercules?
It goes through the master sign program process, required before any changeable copy or digital sign is installed; the Community Development Director acts on standard sign permits under Section 13-34.102, with Planning Commission review reserved for master sign program approvals under Section 13-34.103.
