Full Breakdown
Under Springfield's citywide sign code, a sign placed inside a window facing outward isn't counted as a wall sign at all, so there's no percentage-of-glass limit on it. What is off-limits is applying a sign directly to the exterior face of the glass: that's prohibited outright, with one narrow exception: lettering stating the business's days and hours of operation. A business wanting a coverage-limited exterior window sign would need to be inside the Grant Avenue Parkway overlay district (§ 36-494), which sets 15%–25% caps but applies only along that corridor, not citywide.
Violations & Fines
Applying vinyl lettering, decals, or paint directly to the outside of a storefront window for anything beyond posted hours violates § 36-454(17)(c)(1)(d) and is treated as an illegal wall sign.
