Initial analysis

The 12-unit, 3-story multi-family residential building at 1665 Clay St in Nob Hill, owned by Quong Laurinda, was constructed in 1919 and has undergone several significant maintenance and safety upgrades throughout its history. Most notably, the building completed a mandatory soft-story retrofit in 2017 at a cost of $81,000, bringing it into compliance with seismic safety requirements. Other major improvements include a reroofing project in 2009 costing $18,400, and the replacement of multiple water heaters in 2010. The building has experienced recurrent heating system issues, with multiple complaints documented between 2001-2011 regarding inadequate heat and improper timing settings, including a routine inspection in 2010 that revealed various violations such as problems with the fire escape ladder and self-closing doors. The most recent significant compliance issues were documented in May 2024, when violations were filed regarding fire safety equipment including fire extinguisher tags, the fire escape ladder, and general fire safety compliance, though these were abated by July 2024.

The building's maintenance history shows regular attention to major systems, including plumbing and electrical updates, though some improvements have required multiple permits or extensions to complete. There have been several water-related issues documented through complaints, including leaks in 2011 and 2015, and complaints related to the heating system have been a recurring theme. The building's safety systems have generally been maintained, with no merit found in fire complaints from 2006, 2009, and 2017 regarding alarm systems and sprinkler systems. The property has had regular inspections and completed necessary safety upgrades, including the installation of seismic bracing for water heaters and various bathroom improvements.

Risk rating

How 1665 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

Out of 1125 buildings in this neighborhood, 866 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 16.2%
Moderate concern 49.8%
Severe concern 34.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
