Initial analysis

The two-story, 8-unit multi-family residential building at 1380 Washington Street in Nob Hill, owned by Prudence Investments & Assoc., has a mixed maintenance and compliance history since its 1908 construction. The most significant current issue is an active violation from April 2024 regarding an unpermitted boiler operation, with the most recent permit renewal attempt cancelled in 2019. The building has undergone several substantial improvements, including a comprehensive kitchen remodel in Unit 3 in 2012 (including electrical rewiring, new appliances, and plumbing work), installation of a new steam heating boiler in 2012, and multiple roofing projects, with completed work in 2008 costing $8,000. However, the property has faced several concerning incidents, including a notable bed bug infestation in 2012, sewage issues in 2006-2004, and multiple fire safety violations in 2009, which involved access issues to the boiler room, storage blocking exit stairs, fire extinguisher maintenance, and utility ceiling repairs - all of which were abated by March 2009. Despite these challenges, the building has maintained basic safety systems, with two documented smoke detector activations showing no fire incidents or civilian injuries.

Recent activity at the property has primarily involved external issues such as parking violations and sidewalk cleanliness, with numerous 311 calls in 2024 regarding garbage, debris, and illegal parking. There have been no reported fire incidents or major violations since 2009 related to the building's internal systems, apart from the recent boiler permit issue. The property's maintenance record shows regular attention to major systems, including multiple roof replacements and kitchen remodels, though some permits, including a 2019 reroofing project, were not completed as intended. The building's age and history suggest ongoing maintenance challenges typical of similar vintage structures, with particular attention needed to ensure compliance with current safety and system requirements, as evidenced by the recent boiler permit issue.

Risk rating

How 1380 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.
