Signs and Advertising Washington 3 Minutes Read · published February 10, 2026 Flag of Washington

Tri-Cities, Washington property owners and sign contractors must follow municipal sign codes in Kennewick, Pasco and Richland when installing or operating digital signs. Local ordinances typically regulate maximum brightness, automatic dimming, rotation intervals and permitted zones. This guide summarizes how the Tri-Cities approach digital sign brightness and rotation, where to check code language, how enforcement works and practical steps to apply, appeal or report a problem.

How digital signs are regulated

Municipal sign codes commonly treat electronic message centers, LED signs and animated displays as "electronic signs" or "animated signs." Rules usually cover:

  • Permitted zoning districts and use types.
  • Rotation/animation limits and minimum dwell times for each message.
  • Brightness controls, automatic dimming at night, and maximum luminance (where specified).
  • Safety rules to avoid driver distraction and limits near residential areas.

For specific code text, consult your city sign ordinance or municipal code; for example the Kennewick municipal code and sign regulations provide local definitions and procedural rules for sign permits.[1]

Always verify allowed sign types and permit requirements with the local planning office before ordering a digital display.

Penalties & Enforcement

Enforcement is handled by municipal departments (planning, building, code enforcement or community development). Penalties and remedies vary by city and are typically set in the municipal code or penalty schedule cited by the ordinance.

  • Monetary fines: specific fine amounts for sign violations are not specified on the cited page; consult the municipal code or schedule cited by the sign ordinance.[1]
  • Escalation: many cities use warnings, followed by fines and then continuing daily penalties for unresolved violations; exact escalation steps are not specified on the cited page.[1]
  • Non-monetary sanctions: abatement orders, stop-work orders, permit revocation, and civil actions are commonly authorized by code.
  • Enforcer and complaints: code enforcement or community development departments accept complaints and schedule inspections; use the city complaint/contact page to file reports.
  • Appeals and review: appeals usually go to a hearings examiner or planning commission; time limits for appeal are set in the code or permit decision and are not specified on the cited page.[1]
If you receive a notice about an electronic sign, follow the stated correction timeline immediately to avoid escalating penalties.

Applications & Forms

Most Tri-Cities require a sign permit application, plans showing size/illumination and a site plan. The exact form name, fee and submission method vary by city and are not fully specified on the cited page; contact the local community development or building department for the current sign permit packet and fee schedule.[1]

Action steps to comply

  • Confirm whether your parcel zoning allows digital signs.
  • Obtain a sign permit and submit illumination specifications and automatic dimming settings.
  • Install an automatic brightness sensor or timer if required by code.
  • If cited, follow the correction notice, pay fines if assessed, and file an appeal within the code’s stated deadline.

FAQ

What brightness limit applies to digital signs in the Tri-Cities?
Brightness limits vary by city and by sign type; specific maximum luminance values are not specified on the cited page and must be looked up in each city’s sign ordinance or permit conditions.[1]
How often can a message rotate on an electronic sign?
Typical rules set a minimum dwell time (for example, 6 to 10 seconds) before changing a message, but the exact timing is set in each municipal sign code and is not specified on the cited page.[1]

How-To

  1. Check your city’s sign requirements with community development or planning before purchasing a digital display.
  2. Prepare a sign permit application with drawings, illumination specs and site plan; submit to the city building or planning department.
  3. Install required controls (automatic dimmer, timers) and keep records of calibration and maintenance.
  4. If you observe a noncompliant sign, document location and photos and submit a complaint to the city’s code enforcement office.
