Initial analysis

The three-story, 14-unit apartment building at 1650 Clay Street in Nob Hill was constructed in 1912 and has experienced several significant maintenance and safety issues in recent years. Most concerning is the recent history of heating and electrical problems, including a heater malfunction complaint filed in August 2023, a complete power outage affecting hallways, staircases, lobby, and laundry facilities in March 2024, and inadequate lighting concerns in 2014 that required the installation of daylight sensors. The building received attention for fire safety systems, with violations noted in 2022 for alarm systems, extinguishers, and sprinkler/standpipe systems, though records indicate these issues were subsequently corrected. A recent maintenance issue worth noting is the bathroom ceiling collapse reported in July 2024, which was abated by September 2024.

The property's maintenance history shows periodic roof work, including a $29,000 re-roofing project completed in 2017, and various unit-specific renovations such as a bathroom remodel in Unit 5 (completed in 2008). Historical violations from 2001 highlighted heating system requirements, though most of these issues appear to have been resolved. The building's exterior areas have occasionally required attention, as demonstrated by multiple 311 calls in 2024 regarding garbage and debris. While the building has faced various maintenance challenges over the years, records indicate that most violations were addressed, though there have been persistent issues with heating systems, electrical infrastructure, and various unit maintenance matters that suggest ongoing maintenance challenges within the property.

Risk rating

How 1650 Clay 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
