Summary
Thousand Oaks businesses in commercial and industrial zones can post window signs without a permit, but the display is capped at 25% of the total window area on any street-facing facade during ordinary sales promotions. The City allows two additional holiday-period events each year where a bigger share of the window can be covered, but those special displays are limited to 21 consecutive days each.
(1) Window signs shall be permitted on both the inside and/or outside of the window. No permit shall be required. (2) Window signs shall be limited to twenty-five (25%) percent of the total window area on any single facia of the building fronting on a street to be displayed in conjunction with sales or special events for an indefinite period of time. Additionally, two (2) separate events involving a larger portion of the window beyond the twenty-five (25%) percent may be authorized on holiday periods chosen by the individual business throughout the calendar year and further limited to a maximum of twenty-one (21) consecutive days for each event.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: 2026 S-78: 2026 S-78 Supplement contains: Current city legislation passed through March 31, 2026).
Full Breakdown
The 25% cap applies per building facade facing a street and can be maintained indefinitely for ordinary sales and special events. Businesses get two extra holiday-period windows per calendar year during which they can exceed 25% coverage, but each of those larger displays is capped at 21 consecutive days. Signs that simply say 'open,' 'closed,' or list hours of operation don't count as window signs at all under § 9-4.2303's definitions, so they fall outside these percentage limits entirely.
Violations & Fines
Window signs exceeding the area cap are, like other noncompliant signs under this article, subject to the nuisance-abatement process in § 9-4.2304(e): the Community Development Director notifies the responsible business to bring the display into compliance or remove it, with removal costs billable to the business if the City has to act.
