Initial analysis

The three-story, seven-unit multi-family residential building at 1224-1228 Washington Street in Nob Hill, built in 1916, has undergone several significant maintenance and compliance actions over recent years. Most recently, in May 2023, the building resolved a violation by removing an unpermitted bedroom and bathroom and converting the space back to storage. The property completed a mandatory soft-story retrofit in 2019, adhering to seismic safety requirements at a cost of $45,000. Historical issues from 2004-2005 included multiple building violations regarding inadequate ventilation, electrical system concerns, and water damage, particularly in Unit A, which were all addressed by December 2005.

The building has experienced recurring infrastructure challenges, including sewer repairs (2010), roof work (2005), and various plumbing and electrical updates. Recent fire safety inspections in 2024 revealed some issues with fire alarms and sprinklers, though these were corrected or found to have no merit. The property has also faced parking-related issues, with multiple complaints recorded in 2023-2024. A notable illegal unit situation was resolved in December 2023, and there were some historical concerns about unauthorized renovations and window installations in 2004, though these appear to have been addressed. Recent maintenance records show ongoing attention to building systems, though a missing side sewer vent cover issue reported in October 2023 remains open as of now. The property has successfully completed multiple fire safety inspections, with most recent fire code violations being promptly corrected or found to be without merit.

Risk rating

How 1224-1228 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
