Summary
In unincorporated Kern County, a window sign counts as exempt from Chapter 19.84's sign permit only if it stays under a hard cap: painted glass signs, poster paper signs, and placards on storefront glazing cannot cover more than 50 percent of that glazing. Zoning Ordinance Section 19.84.140(J) sets this threshold; cross it and the display loses its exemption and must meet the chapter's full sign design and permitting standards.
Window display signs limited to painted signs on glazing, poster paper signs, and placards attached to the inside of glazing of store fronts, provided that the store front glazing is not covered in excess of fifty percent (50%);

Full Breakdown
Section 19.84.140 of the Kern County Zoning Ordinance lists seventeen categories of signs, lettered A through Q, that are exempt from Chapter 19.84's permit and design-standard requirements. Subsection J covers window displays: painted signs applied directly to glazing, poster paper signs, and placards attached to the inside of storefront glass. The exemption holds only while the combined coverage of that glazing stays at or under fifty percent. The ordinance measures against the storefront glazing as a whole, not against each individual sign, so a business layering several posters and placards in the same window has to keep the cumulative area under the cap to stay outside the permit process.
Once coverage passes fifty percent, the window display is no longer an exempt sign under subsection J; it becomes a regulated sign subject to the area, height, lighting, and placement standards that apply elsewhere in Chapter 19.84, including the design and development standards for signs attached to buildings under Section 19.84.040. The Kern County Planning and Natural Resources Department administers sign permitting and zoning compliance for the unincorporated county, and a property found in violation is handled through the enforcement chapter, Chapter 19.114, which applies to violations of the entire zoning title, including sign standards.
Violations & Fines
Exceeding the fifty percent glazing cap strips the window display of its exempt status, exposing the property to the misdemeanor enforcement set out in Section 19.114.060: a fine of not more than one thousand dollars, imprisonment in county jail for up to six months, or both, with each day the violation continues counted as a separate offense. The county may also pursue administrative penalties under Chapter 8.54 or record a notice of zoning violation against the property under Section 19.114.065.
