Summary
Compton confines electronic reader boards and LED billboard faces to the Billboard Overlay (B-O) Zone. Off-site displays there need a Zoning Permit, a Sign Permit, a Building Permit and City Council approval before any digital face can go up.
This subsection does not prohibit properly maintained reader boards or LED displays that comply with State and Federal law and subsection 20-22.2 entitled Flashing, intermittent or moving light. ... Notwithstanding the foregoing, the installation of electronic readerboards shall only be allowed to be installed on billboards that are located within a B-O Zone.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: rev 4952997; v15 updated 2026-07-14; through 07-14-2026).
Full Breakdown
9, off-site outdoor advertising displays are allowed only in B-O Zones, and paragraph (a)(6) carves out an exception letting properly maintained reader boards or LED displays operate there if they comply with state and federal law and the code's flashing-light rule. Paragraph (c) tightens that further for retrofits: existing billboards may keep their message and even add extensions to their facing, but converting a static face to an electronic readerboard is only allowed if the billboard already sits inside a B-O Zone. Any new off-site display, digital or static, needs a Zoning Permit, a Sign Permit and a Building Permit under (a)(10), and no permit issues without prior City Council approval under (a)(11).
The Council (or the Planning Commission on referral) must find the display is scaled to the site's architecture, results in a visually uncluttered appearance, does not obscure historic buildings or public art, and minimizes traffic hazards before signing off. ) and any conflicting local sign rule yields to that state law under (a)(8). A single cylindrical column support is required for the structure, and Architectural Review Board and Design Review sections do not apply to these applications since the Council conducts its own findings-based review instead.
Violations & Fines
Displays installed without the required Zoning, Sign and Building Permits, or without prior City Council approval, are treated as illegal signs under § 30-22.8 and declared a public nuisance subject to abatement. The City mails and posts notice giving the owner 30 days to remove or fix the display, with a right to appeal in writing to the Planning Director before the 30 days runs. If the owner misses the deadline the City removes the display itself, stores it 30 days for recovery on payment of removal and storage costs, and unpaid removal costs become a lien against the property.
