Sign Regulations in Kent, WA

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

Digital Billboards

Kent City Code flatly bans off-premises billboards that use electronic video displays resembling a television screen. The city also freezes the total number of billboard structures at the count that existed on March 5, 2000, and confines any new or relocated billboard to the I1, I2, and I3 industrial zones under KCC 15.06.040(S).

Key details: Digital video billboards: Prohibited outright, citywide. Billboard count cap: Frozen at March 5, 2000 total. Allowed zones: I1, I2, I3 industrial only. Max sign face: 300 square feet. Max height: 35 feet.

An off-premises sign found in a state of disrepair, or one that violates the electronic-video ban, districting rules, or size limits, is subject to enforcement under KCC 15.10.070. The Kent building official can pursue a civil code violation with a monetary penalty and abatement order under Chapter 1.04 KCC, refer the matter for criminal misdemeanor prosecution under KCC 1.04.030(B), or issue a class 1 civil infraction under RCW 7.80.120.

Compared to other cities, Kent takes a harder line on digital billboards. The enforcement and penalty structure reflects that.

Window Signs

Kent counts window signs toward a property's overall sign area and sign count, so a business cannot dodge its aggregate cap by moving graphics inside the glass. KCC 15.06.040(I) treats a painted-over window as a wall, and carves out only credit-card decals and holiday or promotional window banners from that count.

Key details: Governing section: KCC 15.06.040(I), Window signs. Counts toward: Aggregate sign area and sign count. Painted-over window: Treated as a wall. Exempt: credit card decals: No permit, not counted. Exempt: inside window banners/posters: Holiday, weekly-special, national ad programs.

Window signage that pushes a property's total sign area or sign count over the district limit is treated the same as any other unpermitted sign under Kent's sign code: the planning department can require removal or a permit application to bring the display into compliance, and unresolved cases move to code enforcement for notice and correction. Painting over a window to disguise it as unregulated space does not avoid this exposure, since KCC 15.06.040(I) reclassifies that surface as a wall for sign-area purposes.

Garage Sale Signs

Kent allows garage-sale signs as a temporary-use sign under KCC 15.08.205(A)(11), with no permit needed. Signs must stay on the sale property, run only for the duration of the sale, and are capped at two signs per use, eight feet tall, and 32 square feet of total sign face.

Key details: Permit needed: None, per KCC 15.08.205(A)(11). Max signs per sale: Two. Max sign size: 32 sq ft total face. Max sign height: 8 feet. Location: On-premises only, no off-site signs.

Posting more than two garage-sale signs, using a sign larger than 32 square feet or taller than eight feet, or placing a sign off the sale property, such as at a street corner or on a neighbor's lawn, violates KCC 15.08.205(A)(11) and can be ordered removed by the planning department as a temporary-use sign violation, even though no permit is required to post compliant signs.

The rules around garage sale signs in Kent lean permissive, but that does not mean anything goes.

The Bottom Line

Kent'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 Kent is broadly strict or permissive.
