Parker, CO Sign Regulations: Window Signs (2026)

Section 13.09.040(e)(1) folds window signs into the Table 13.09.B schedule that governs temporary signage on developed parcels, and the Window row sets the coverage rule apart from every other sign type on that table: the limit is calculated as a percentage of window area rather than a flat square footage. A single occupant of a parcel, such as one storefront in a multi-tenant retail center, may cover up to 25 percent of its aggregate window area with temporary signage, or 150 square feet, whichever number is smaller.

Unlike banners, freestanding signs, sandwich boards, and construction signage, which all carry a display-duration limit in that same table, the Window row lists None for duration, so a compliant window sign can stay up indefinitely without triggering the ninety-day cycle that applies to freestanding temporary signs. Separately, Section 13.09.020(c)(12) exempts any window sign under six square feet from the Sign Code altogether, meaning small paper notices or hour-of-operation signs never need to be measured against the 25-percent/150-square-foot cap or registered under Section 13.03.040(o). Once a tenant's window signage crosses that six-square-foot threshold, however, it counts toward the aggregate limit and must be registered like any other temporary sign, calculated per occupant so that neighboring tenants sharing one storefront each get their own allowance rather than splitting a single parcel-wide cap.
