Seattle Sidewalk Repair: Who's Responsible, Permits and Process
Last Updated: 10/12/2026In Seattle, the cracked or root-lifted sidewalk in front of your house is usually your problem, not the City's. Seattle Municipal Code Chapter 15.72 lets the Seattle Department of Transportation (SDOT) order the abutting property owner to repair a sidewalk that is unfit or unsafe for public travel. This guide covers who is responsible for what, which Street Use permit fits your repair, how the process runs from notice to inspection, what drives cost, and how street trees change the picture.
Who is responsible for the sidewalk next to your property
SDOT's guidance is direct: property owners maintain the sidewalks adjacent to their property, including the planting strip, the roadway shoulder where no sidewalk exists, and unpaved alleys next to the lot. The City steps in only in specific situations.
| Situation | Who handles it |
|---|---|
| Cracked, broken, or lifted sidewalk next to private property | Abutting property owner |
| Snow, ice, leaves, debris, and overgrown plants | Abutting property owner |
| Damage caused by a City-owned tree or City sewer line | City of Seattle |
| Damage caused by another City agency or a public utility | Referred to that agency or utility |
| Street tree planted by a resident, with or without a permit | Abutting property owner maintains it |
| Sidewalk adjacent to City-owned property | Eligible for SDOT's Sidewalk Repair Program |
SDOT may place temporary measures such as warning paint, asphalt shims, or beveled uplifts while it determines responsibility. A shim is not a permanent repair.
Which Street Use permit you need
A permit is required before any sidewalk repair in the right-of-way. SDOT's Sidewalk Maintenance and Repair Guide (AG 1011) sets the permit type by the size of the repair area:
| Repair area | Permit type |
|---|---|
| Under 100 square feet | Right-of-Way Maintenance Permit |
| 100 to under 2,000 square feet | Right-of-Way Construction Permit |
| 2,000 square feet or more | Street Improvement Permit |
The Maintenance permit is limited to minor mobility impacts, such as sidewalk closures under 5 days on an arterial or 20 days on a non-arterial street. If the repair also touches your curb cut or driveway apron, see our Seattle driveway approach permit guide.
The SDOT sidewalk repair process, step by step
- Notice or self-inspection: SDOT can serve a notice under SMC 15.72.010 instructing you to repair the sidewalk within a reasonable time stated in the notice. You don't have to wait: SDOT asks owners to watch for wide cracks, raised sections, missing pieces, and standing water.
- Check for a street tree: if roots are involved, contact an SDOT arborist at (206) 684-TREE before work starts.
- Hire a contractor: replacing concrete panels usually calls for a contractor, who can also help with the permit.
- Apply: submit through the Seattle Services Portal under Permits-Street Use. A Maintenance permit needs a Right-of-Way Impact Plan, plus a Traffic Control Plan if the work affects mobility. SDOT provides an online fee estimator.
- Issue and schedule: pay to issue the permit, then schedule a job start notification before work begins.
- Coordinate with your inspector: contact your district Street Use inspector to plan the work. Repairs must meet City of Seattle standards.
An unanswered notice can end with SDOT doing the work and the cost becoming a lien (see the FAQ below). If SDOT agrees, an owner can also contract with SDOT for the repair and be billed.
What drives the cost of a sidewalk repair
| Cost driver | Why it matters |
|---|---|
| Area and number of panels | Sets the permit tier and the volume of demolition, base prep, and concrete |
| Tear-out and haul-off | Broken panels are removed and disposed of before the new pour |
| Tree roots | Arborist coordination, root work, and sometimes forming around the tree |
| Grade and drainage | New panels must tie into adjacent walks, curbs, and driveways and shed water |
| Traffic control and staging | Closures, signage, and an impact plan add prep time |
| Permit and inspection | SDOT fees, plus scheduling around the job start and inspection |
A site visit is the only reliable way to price the work. Our concrete sidewalk services cover tear-out, forming, and replacement, and concrete repair handles cracked walks and steps on the private side of the property line.
Pacific Northwest factors: roots, rain, and moss
Street trees and a wet climate drive most Seattle sidewalk failures. Roots growing under the slab lift panels and create trip edges. Long rainy seasons keep subgrade soil soft, so panels settle unevenly and hold standing water. Shaded walks under tree canopy grow moss that makes concrete slick all winter; see our guide to moss and mildew on Seattle concrete. Schedule replacement pours around dry stretches so new panels cure without rain damage.
Frequently asked questions
Who is responsible for repairing the sidewalk in front of my house in Seattle?
The abutting property owner. Seattle Municipal Code Chapter 15.72 and SDOT guidance make owners responsible for keeping the adjacent sidewalk safe, including repairing cracks and other damage and clearing snow, ice, and debris. The City takes responsibility when the damage is caused by City infrastructure such as a City-owned tree or sewer line.
Do I need a permit to repair a sidewalk in Seattle?
Yes. SDOT requires a permit before sidewalk repair work starts. Repairs under 100 square feet use a Right-of-Way Maintenance Permit, repairs under 2,000 square feet use a Right-of-Way Construction Permit, and repairs of 2,000 square feet or more need a Street Improvement Permit.
What happens if I ignore an SDOT sidewalk repair notice?
Under SMC 15.72.040 and 15.72.050, SDOT can make the repair itself and report the cost to the City Council, which can assess that cost against your property. The assessment becomes a lien on the property.
Who pays when street tree roots damage the sidewalk?
It depends on who owns the tree. If a City-owned tree is causing the damage, the City takes responsibility for the repair. Street trees planted by residents, with or without a street tree permit, are the abutting owner's responsibility to maintain. SDOT's Seattle Tree Inventory can help you check whether a tree is City-owned.
Can I cut tree roots to fix my sidewalk?
Not on your own. Before pruning street tree roots greater than 2 inches in diameter, you must arrange for an SDOT arborist to evaluate how the pruning will affect the tree's health and public safety. Tree pruning and removal in the public right-of-way also requires a Street Use permit. Call 684-TREE (8733).
