Full Breakdown
Portland's sign code (Title 32) exempts most signs placed inside a building, including window displays, from its permit and size regulations. That exemption breaks down for illumination: City Code § 32.12.020(B)(1) strips the exemption from illuminated signs in windows within the OS, RF through RM4, RMP, CI1, CR, and IR zones, mostly residential, campus-institutional, and commercial-residential districts. Once the exemption is lost, the illuminated window sign counts against the site's permitted sign area, count, and type under the Chapter 32.32 base-zone tables and needs a permit. Non-illuminated window signs stay exempt in every zone citywide.
Violations & Fines
Portland Permitting & Development administers Title 32. An illuminated window sign in an affected zone that exceeds the Table 1 size, count, or type limits for the site is a code violation, subject to permit correction or removal on order of the Director.
