Summary
In the City of Yorba Linda, a window sign showing open or closed status, or posted business hours, is exempt from sign permitting under Municipal Code Section 18.24.090(A) as long as it stays under two square feet in area. Anything larger falls outside this narrow carve-out and needs a standard sign permit under the rest of Chapter 18.24.
In all zones, the following signs shall be exempt from the provisions of this title: A. Open/closed window signs less than two square feet in area. This sign may also include hours of operation. B. Interior signs located within the interior of buildings when such signs are not visible from outside the subject building. C. A United States, California or City flag. D. Directional safety signs, such as "Stop," "Yield," and similar signs, the face of which meet California Department of Transportation standards and bear no commercial message of any sort. E. Trespassing and property alarm signs less than two square feet in area. F. Any official government sign, public notice or warning required by a valid and applicable Federal, State or local law, regulation or ordinance. G. Other similar signs deemed by the Community Development Director, such as signs not visible from the public right-of-way or from private streets.
Full Breakdown
Section 18.24.090 lists the sign types that businesses and residents in Yorba Linda can post without going through the sign permit process the rest of Chapter 18.24 requires. Subsection A covers open/closed window signs: they are exempt outright as long as they stay under two square feet in area, and the same small sign can also show the business's hours of operation without separate approval. The exemption sits alongside a short list of other sign types the City treats the same way. Interior signs are exempt if they are not visible from outside the building, which covers most menu boards, directories or notices posted inside a storefront.
A trespassing or property alarm sign is exempt on the same two-square-foot threshold used for window signs. United States, California and City flags are exempt outright, as are directional safety signs, such as stop or yield signs, that meet California Department of Transportation standards and carry no commercial message, and any official government sign or notice required by federal, state or local law. Finally, the Community Development Director has discretion to treat other similar signs as exempt, specifically citing signs not visible from the public right-of-way or from private streets, which gives the City a catch-all for small interior or low-visibility displays that do not fit neatly into the other categories.
A retailer that wants a larger illuminated open/closed display, or one that exceeds two square feet, has to apply for a standard wall or window sign permit under the general provisions of the chapter instead of relying on this exemption.
Violations & Fines
A window sign that exceeds two square feet, or an open/closed display marketed as exempt when it carries additional advertising copy, no longer qualifies under Section 18.24.090(A) and is treated as a standard sign requiring a permit. The Community Development Director enforces the sign chapter and can require the display to be permitted, resized or removed if it does not fit an exempt category.
