Unincorporated Benton County does not regulate holiday lights, inflatables, or yard displays on private property, and Washington has no statewide holiday-display law. No county permit is needed. In a deed-restricted subdivision, HOA covenants set the only real limits.
There is no Benton County ordinance governing Christmas lights, seasonal inflatables, or other holiday decorations on private residential property, and Washington has no statewide holiday-display statute. A homeowner in the unincorporated county may decorate without a county permit. Practical limits still apply: a display cannot block a public sidewalk or road or sit in the right-of-way, outdoor electrical work should use exterior-rated equipment, and noise-making decorations fall under the general noise ordinance. In a deed-restricted subdivision the HOA's covenants control display duration, size, and inflatables. Kennewick, Richland, West Richland, and Prosser apply their own codes inside city limits.
The county does not cite holiday displays on private property; only an obstruction of the right-of-way or an electrical hazard draws a correction notice. Within an HOA, out-of-season displays carry the covenant fines the association sets.
