Carroll County, MD Sign Regulations: Window Signs (2026)

111 lists categories of signs a property owner may post in any zoning district without a zoning certificate, and division (H) goes further than the rest of the list: rather than setting a size or placement condition, it removes interior store window signs from regulation entirely, alongside political signs. This sits in contrast to nearly every other sign type addressed in the same section, such as the home occupation sign capped at three square feet under division (A) or the temporary real estate sign rules under division (D), which specify exact dimensions, placement setbacks, and removal deadlines.

Because interior window signage is exempt outright, a retailer or home-based business operating in the unincorporated county can change window displays and promotional signage inside a storefront without seeking Zoning Administrator approval or tracking a square-footage limit. The exemption covers only the inside of the window; any sign mounted on the exterior of the building, including on the outside of window glass, is a separate sign type subject to whichever provision of Chapter 158 governs its type and location. 110 confirms these sign provisions, including the window-sign exemption, apply only in the unincorporated areas of Carroll County, not inside its incorporated towns.
