# Washington Sidewalk Law: You Can Be Billed, but the Statute Gives You Two Real Shields

> RCW 35.69.020 lets Washington cities put sidewalk costs on the abutting owner, but caps the bill at 50% of your land value and zeroes it entirely when the city caused the damage.

Washington state law lets cities push sidewalk construction and reconstruction costs onto the abutting property owner. Most owners stop reading there. The same statute contains two protections that almost nobody invokes, because almost nobody knows they exist.

## The default: the cost devolves onto you

RCW 35.69.020(1): where a sidewalk is unimproved or unsafe, "the duty, burden, and expense of constructing or reconstructing such sidewalk shall devolve upon the property directly abutting upon such portion," except as provided in the two subsections that follow. That is the owner-pays default, in statute, statewide.

## Shield one: the 50% valuation cap

RCW 35.69.020(2): "An abutting property shall not be charged with any costs of construction or reconstruction under this chapter, or under chapter 35.68 or 35.70 RCW, in excess of fifty percent of the valuation of such abutting property, exclusive of improvements thereon, according to the valuation last placed upon it for purposes of general taxation."

The cap is measured against the land value alone, not the house. On a small or low-valued lot with an expensive sidewalk project, this cap has teeth. Check your county assessor's land valuation before accepting any large sidewalk assessment.

## Shield two: if the city caused it, you owe nothing

RCW 35.69.020(3): no reconstruction charge when the work "is required to correct deterioration of or damage to the sidewalk that is the direct result of actions by the city or its agents or to correct deterioration of or damage to the sidewalk that is the direct result of the failure of the city to enforce its ordinances."

City tree roots, city utility work, or damage the city allowed to happen by not enforcing its own rules: all arguably inside this exception. Before paying, ask in writing what caused the damage, because the answer decides whether subsection (3) applies.

## How this plays out in practice

Seattle is the documented example: the City Auditor's own 2021 report found that the state-law enforcement mechanism against owners "has never been used in Seattle," while the city acknowledges responsibility for roughly 15-20% of its sidewalks (city trees, city utilities, city property).
