Initial analysis

The 12-unit multi-family residential building at 1641 Washington Street in Nob Hill, owned by Wayne & Jeannie Young Living Trust, has experienced several significant events since its construction in 1909. Most notably, in February 2021, the building suffered fire damage affecting Units 5 and 9, as well as the roof, with the fire discovery revealing issues related to excessive clutter and security concerns. In response to the fire incident, extensive remodeling was completed in late 2021 for Units 5 and 9, including electrical rewiring, installation of new shower pans, and general renovations costing approximately $80,000.

Prior to the fire, the building had several maintenance issues that required attention, including deck and stair repairs in 2011 related to safety violations, and reroofing projects in 2016 and 1991. Multiple housing code violations were documented between 2001 and 2011, including concerns regarding fire escape maintenance, smoke enclosure doors, egress obstruction, and security devices, though most of these violations were eventually abated. The building's most recent service calls have primarily been related to parking enforcement matters outside the property. Since the 2021 fire and subsequent renovations, there have been no recorded violations or major incidents, suggesting improved building conditions. However, the building's history shows a pattern of maintenance and compliance challenges, particularly concerning fire safety and security requirements, though these appear to have been addressed through various permitted improvements.

Risk rating

How 1641 Washington St'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.

Neighborhood percentile

Out of 1125 buildings in this neighborhood, 889 are predicted to be safer.
