Full Breakdown
11, part of the 2019 Title 23 zoning rewrite that took effect January 1, 2020. 05(2)(a). The coverage math runs two ways: no single window may show more than 50 percent sign coverage, and total window signage on any building facade, story by story, cannot exceed 20 percent of the glass area on that facade level. Because the rule is written as a percentage of window and facade area rather than a flat square-footage cap, it scales with storefront size, from a single tavern window to a multi-bay commercial block downtown.
The category applies the same across every zoning district open to the underlying land use; there is no residential-versus-commercial split in the coverage percentages themselves. A window sign must be built of paper, vinyl, or similarly lightweight material and mounted on the interior glass; no sign permit or Zoning Administrator sign-off is required before installation, unlike most permanent business signs. Lighting is limited to ambient light plus up to one internally illuminated or neon sign per tenant space. The code also fixes what counts as a single 'window' for the math: it is the full area inside a window frame, which may itself be divided by muntins or mullions, while panes separated by a wall, pier, or column count as separate windows for the coverage calculation.
Violations & Fines
Window signs exceeding the 50 percent single-window or 20 percent per-facade cap, or built of non-lightweight material, are treated as ordinary zoning violations. The Zoning Administrator can order correction under Section 23.10.60, and unresolved sign violations elsewhere in Article IX carry a 60-day notice-to-correct before permit revocation and City-ordered removal at the owner's expense under Section 23.09.27(8).
