Sign Regulations in Portland, OR

If you live in Portland or are thinking about moving there, sign regulations are one of those things you probably won't think about until they affect you directly. Portland has 3 specific rules on the books covering different aspects of sign regulations, and some of them might surprise you.

Window Signs

Non-illuminated signs placed inside Portland windows are exempt from the sign code, but illuminated window signs lose that exemption in the OS, RF through RM4, RMP, CI1, CR, and IR zones and must meet full permanent-sign standards there.

Key details: Governing code: Portland City Code § 32.12.020(B). Non-illuminated window signs: Exempt from Title 32 citywide. Illuminated window signs: Not exempt in 7 listed zones. Affected zones: OS, RF-RM4, RMP, CI1, CR, IR. Enforcing agency: Portland Permitting & Development.

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.

Digital Billboards

Portland caps changing image sign features, its term for digital displays, at 20 square feet total per site under Title 32, with brightness limits, a narrow sports-field exception, and looser rules inside the Rose Quarter Entertainment Sign District.

Key details: Citywide size cap: 20 sq ft combined per site. Single sign limit: 10 sq ft unless under 60% of face. Restricted zones: Barred in RX, CI1, CM1 zones. Sports field exception: 1 hr before/after event only. Civil penalty: Up to $1,000 per violation.

Sign code violations, including unauthorized changing image features, draw civil penalties up to $1,000 per incident under § 32.66.020, and each day of non-compliance counts as a separate violation.

This is one of the stricter rules in Portland's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Political Signs

Portland has no separate political-sign ordinance; campaign yard signs are regulated the same as any other lawn sign under Title 32: capped at 3 square feet with no permit required.

Key details: Max size: 3 square feet. Placement: Entirely outside right-of-way. Permit: None required. Illumination: Prohibited. Max civil penalty: $1,000 per violation.

Bureau of Development Services can order a noncompliant sign corrected or removed; refusing to comply is a violation carrying civil penalties up to $1,000 per violation, with each day of continued noncompliance counted separately.

Portland is more permissive than most cities when it comes to political signs. That said, there are still limits.

The Bottom Line

Portland's sign regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Portland is broadly strict or permissive.

Keep in mind that Portland can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
