Summary
Howard County lets a business post unlimited interior window signs, but their combined area cannot exceed 20 percent of the window glass on that side of the building. An extra 20 percent is allowed on a temporary basis, plus another 10 percent temporarily for nonprofit messages. Illuminated window signs still need a permit.
(d)Window Signs. There shall be no limit to the number of such signs; provided, however, that the total area of all window signs shall not exceed 20 percent of the window glass area, which shall be calculated separately for each side of the building. An additional 20 percent of the window area may be used on a temporary basis. An additional ten percent of the window area may be used on a temporary basis to advertise nonprofit activities.

Full Breakdown
502(d) of the Howard County Code, part of the countywide sign subtitle, governs window signage in every zoning district. There is no cap on the number of signs in a storefront window, only on total coverage: the combined area of all window signs is measured against the glass area of each building side separately, so a corner store with glass on two elevations gets a 20 percent allowance on each side rather than one combined pool. A retailer running a seasonal sale or holiday promotion can add another 20 percent of window area on a temporary basis without seeking a variance, and a nonprofit event notice can claim an additional 10 percent on top of that, meaning window coverage can briefly reach half the glass area when the base, temporary, and nonprofit allowances stack.
509(e)(3), nonilluminated window signs are specifically exempted from the general sign permit requirement, so a paper sale sign taped inside the glass needs no paperwork from the Department of Inspections, Licenses and Permits. 508. The rule applies to every commercial, industrial, and Downtown Columbia storefront alike; it does not vary by neighborhood or shopping center.
Violations & Fines
The Department of Inspections, Licenses and Permits can order removal of an oversized window display with ten days' written notice under subsection 3.511(d); noncompliance lets the County remove it and bill the owner. Violating the sign subtitle is a misdemeanor carrying a fine of $250 to $500 under subsection 3.512(c)(1), or it may instead be pursued as a Class C civil offense under Title 24, with each day of continued violation charged as a separate offense.
