Does a wall near a Seattle street need an SDOT permit?
Possibly, but ‘near the street’ is not the test. First locate the legal property and right-of-way lines. Separate the permanent wall or stair from temporary construction use, excavation and shoring influence, utilities, driveway or sidewalk changes, and impacts to people walking, biking, driving, parking, or using transit. Each can trigger a different SDOT review or permit.
A private wall can remain entirely on private property while deliveries, equipment, a dumpster, access, or restoration still use the right-of-way. Conversely, a permanent private structure in the right-of-way can require an annually renewable Long Term Use permit. Coordinate the SDCI and SDOT paths early and use the property-line guide for ownership and boundary evidence.
Locate the right-of-way instead of estimating from pavement
SDOT notes that the public right-of-way includes streets, sidewalks, and planting strips and can extend beyond the visible improved area into space that appears private. A curb, fence, hedge, old wall, or tax-lot map is not a substitute for the survey and title information appropriate to the project. Show the property line, right-of-way line, easements, wall face and footing, stairs, fence, drainage, utilities, excavation, anchors, driveway, and construction zone on one coordinated plan.
SDCI says walls near a property line or right-of-way must be on the owner’s property unless additional right-of-way requirements are followed. Resolve the permanent footprint before selecting the wall system because footings, reinforcement, anchors, drainage outlets, or guard attachments can cross a line even when the visible face does not.
Separate four municipal scopes
Owners often ask for ‘the street-use permit’ as if one record covers everything. SDOT publishes distinct pathways for a permanent private structure or use, temporary right-of-way construction activity, traffic control, and shoring review associated with excavation. Utility, tree, driveway, curb, sidewalk, or Street Improvement Plan work can add other branches.
Put each branch in a responsibility matrix with the applicant, designer, submittal, fees, review dependencies, inspections, notifications, renewal, restoration, and closeout. An SDCI construction permit does not silently grant use of the right-of-way, and an SDOT construction-use permit does not approve the private structural wall.
| Scope | Typical question | Ongoing consequence |
|---|---|---|
| SDCI wall permit | Is the private wall, grading, and associated work approved? | Build and inspect to approved construction documents. |
| SDOT Long Term Use | Will a private wall, stair, fence, or other use remain in the ROW? | Maintain the permit, structure, fees, and possible future removal obligations. |
| ROW Construction | Will access, deliveries, equipment, materials, dumpster, or restoration occupy the ROW? | Follow approved duration, footprint, protection, and restoration conditions. |
| Traffic Control Plan | Will the work affect public mobility enough to require a TCP? | Maintain the approved routing, work-zone devices, contacts, and notifications. |
| Shoring review | Could private excavation affect street or utility support? | Coordinate SDCI issuance with SDOT review and inspections where applicable. |
The project may need several scopes; the responsible agencies determine the actual requirements.
Permanent encroachment is not a one-time construction approval
AG 1090 says private walls, rockeries, fences, and stairs in the right-of-way are handled through an annually renewable Long Term Use permit. SDOT discourages private structures there when they can be placed on private property and warns that owners may be required to remove them in the future. The published process includes issuance, inspection, possible occupation fees, and annual renewal fees.
That ongoing obligation belongs in design and property records. Ask who is the permit holder, what area is authorized, how inspection and maintenance occur, whether insurance or indemnity conditions apply, how fees can change, and what happens on sale. Do not treat an old wall’s physical presence as evidence of a current transferable authorization.
Temporary staging can trigger SDOT review even for a private wall
AG 1001 lists work-zone setup, site access, deliveries, equipment, dumpsters, materials, scaffolding, and certain driveway work among temporary construction activities in the right-of-way. A narrow lot or hillside may make public-space staging attractive, but availability, duration, vehicle position, crane use, curb reservation, pedestrian routing, and restoration must be approved rather than assumed in the bid.
When a Traffic Control Plan is required, AG 1005 calls for current street conditions and the work and staging footprint, pedestrian or bicycle routes, lane widths, neighboring access, temporary parking restrictions, traffic-control devices, and project contacts. The TCP is a safety and mobility plan; it does not replace the contractor’s private-site lift, access, excavation, or fall-protection planning.
Check excavation influence, not only the wall face
SDOT’s shoring page says Street Use review begins for proposed excavation deeper than three feet immediately adjacent to a public right-of-way and also describes a one-horizontal-to-one-vertical influence line from the property/right-of-way boundary. SDCI initiates the coordinated review when applicable and does not issue until the assigned SDOT location is approved.
Show temporary cuts, shoring, tiebacks or anchors, drilled elements, equipment, dewatering, surcharge, and sequence relative to the line and utilities. A final wall on private property can still have an excavation or anchor geometry that affects the public realm. The same screen does not resolve protection of neighboring private property, which remains a separate design and permit question.
Permit descriptions reveal coordination—not universal rules
Completed permit 6980812-CN includes a revision reducing the wall length so it would not extend into the right-of-way and states there would be no new curb cut. Completed permits 6928264-CN and 6936052-CN explicitly state that separate SDOT permits are required for work in the right-of-way. These are useful examples of boundaries and separate approvals appearing in SDCI records.
The descriptions do not prove which SDOT records were issued, what temporary occupation occurred, or what another site requires. Search the linked project records and ask the agencies about the current proposal. Never infer that a separate-permit note authorizes construction or that silence means no SDOT scope applied.
Make municipal responsibilities comparable in contractor bids
Issue every bidder the same survey, wall and excavation drawings, access plan, preliminary permit matrix, anticipated right-of-way footprint, traffic-control requirements, utility information, work hours, restoration limits, and schedule dependencies. Ask each company to identify which applications, plans, bonds, fees, inspections, renewals, notifications, flaggers, parking reservations, and closeout records it includes.
Verify current Washington contractor registration as L&I recommends, but do not confuse registration with an SDOT permit or approved traffic-control plan. Keep allowances visible and require written authorization for changes in duration or footprint. Municipal charges and review conditions can change, so use current agency information rather than copying a prior project’s price.
A seven-step Seattle ROW coordination workflow
Survey the legal limits
Locate property, right-of-way, easements, utilities, wall components, drainage, excavation, access, and adjoining improvements.
Draw permanent and temporary footprints
Separate the finished structure from excavation, shoring, anchors, equipment, deliveries, staging, traffic control, and restoration.
Build the permit matrix
Identify SDCI, Long Term Use, ROW Construction, traffic-control, shoring, utility, tree, driveway, and other possible branches with the agencies.
Coordinate reviews early
Align the SDCI wall and excavation documents with SDOT requirements and sequencing before final bids or mobilization dates.
Issue one municipal scope
Give every bidder the same application, fee, plan, inspection, notification, renewal, protection, and restoration assumptions.
Verify before occupying the ROW
Confirm permits are issued, approved plans are current, contacts and notices are in place, and the field footprint matches the authorization.
Close and maintain
Complete inspections and restoration, retain final records, and continue any Long Term Use renewal and maintenance obligations.
Frequently asked questions
Is the planting strip always public right-of-way?
It commonly lies in the right-of-way, but do not infer the legal line from appearance. Obtain appropriate survey and property information and confirm the proposed footprint with the responsible agencies.
Can an SDOT permit replace the SDCI wall permit?
No. They address different scopes. A project may need SDCI approval for the wall and grading plus SDOT approval for permanent or temporary right-of-way impacts.
Separate the wall from its public-space impacts
Locate the legal line, map every permanent and temporary footprint, and compare bids only after the SDCI and SDOT responsibilities are explicit.
