Initial analysis

The 4-unit multi-family residential building at 639 Lincoln Way, located in San Francisco's Inner Sunset neighborhood, is a 2-story apartment structure built in 1924, currently owned by Trainer Rush & Karen. The building's maintenance record over the past two decades shows three routine housing inspections: in May 2001 and April 2011, both of which were promptly completed within the same day, and most notably a recent heating system complaint filed in May 2023 regarding an extended period without heat in one unit lasting into its second week. This heating complaint, which is particularly concerning from a resident comfort and safety perspective, remains in a not-active status in the system as of this report date.

Additional records show a minor parking-related issue from April 2023 involving a defaced sign, which was resolved through the Department of Parking and Traffic SignShop. While the historical inspection records suggest regular oversight of common areas during the specified routine inspections, the gap between the 2011 inspection and the recent heating complaint may indicate a lack of documented inspections for this period. Given the age of the building and the relatively recent heating system complaint, this case warrants attention to the building's current mechanical systems performance.

Risk rating

How 639 Lincoln Way's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
