Initial analysis

The 10-unit, 3-story multi-family residential building at 1140 Clay Street in Nob Hill, owned by Amy Lee, was constructed in 1910 and has undergone several significant maintenance updates over its lifetime. The most concerning recent incident occurred in early 2024, involving a sewage backup from a vent that contaminated soil in the backyard, which tenants reported was not properly remediated. The building has a documented history of fire safety issues, with multiple violations recorded in 2016 related to sprinkler service, non-conforming door hardware, and storage in exit pathways, all of which were subsequently corrected. Other fire safety compliance matters have been noted periodically, including alarm system and extinguisher issues in 2020, 2018, and 2008, with most being promptly addressed.

The building's maintenance record shows consistent attention to infrastructure needs, including a major window upgrade in 1992 involving the installation of 47 aluminum windows, and roofing work completed in 1989 and 2008. Several routine inspections and violations have been recorded over the years, with the majority being abated promptly. Recent complaints from 2024 indicate ongoing maintenance issues, including general maintenance concerns that were investigated but not detailed in the available records. The property has experienced recurring issues with garbage and debris management in the surrounding area, as evidenced by multiple 311 calls between 2018 and 2024, though these are generally related to exterior conditions rather than building maintenance. While the building has faced various regulatory and maintenance challenges over its history, most issues have been addressed through the appropriate channels, with the exception of some recent concerns regarding sewage management and general maintenance.

Risk rating

How 1140 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
32th percentile

Out of 1125 buildings in this neighborhood, 765 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 34.8%
Moderate concern 49.0%
Severe concern 16.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
