The incident report may say only "tenant slipped," but what matters for a Washington claim is proof the landlord knew or should have known the stair hazard existed and failed to fix or warn about it.

In the next 24 hours: document the condition before it changes. Take clear photos and video of the exact stairs, lighting, handrails, loose nosing, water, ice, broken concrete, or uneven risers. Capture the whole stairwell and close-ups. Save the shoes and clothes you wore. Get medical care the same day; if the injury is serious, records from Harborview Medical Center or the first treating facility help tie the fall to the stair defect. Report the fall to apartment management in writing and keep a screenshot. Ask for a copy of any incident report. If you do not read English well, request written translation or an interpreter before signing anything.

In the next week: get proof of notice. Ask neighbors whether they complained earlier about the same stairs, rail, or lighting, especially over a holiday weekend when building traffic is heavier. Save texts, emails, maintenance requests, rent-portal messages, and prior photos. If there are cameras, send a written request that the apartment preserve surveillance video from at least 2 hours before and after the fall. Check whether Bellevue Fire or the City of Bellevue Code Compliance was previously alerted about broken stairs, lighting, or unsafe common areas. Under RCW 59.18.060, landlords must maintain common areas in reasonably safe condition.

In the next month: collect the records that prove damages and fault together: medical bills, work-loss records, prescriptions, and follow-up restrictions. Ask for the property's insurance information. Do not give a recorded statement or sign a broad medical release you cannot read. Washington uses comparative fault under RCW 4.22.005, so insurers often argue you were not watching where you walked; photos, witness statements, and prior complaints are what defeat that. The general lawsuit deadline is 3 years under RCW 4.16.080.
