Initial analysis

The three-unit residential building at 1251-1255 Clay Street in Nob Hill is a three-story flats and duplex structure built in 1910, currently owned by Raymond Yip Maa Tr. The building has undergone several significant maintenance and compliance updates over the years, with the most recent being the replacement of three electrical service panels in November 2023, maintaining 100-amp service. In 2016, the building faced multiple violations during a routine safety inspection, including issues with structural maintenance, damaged/peeling paint (with lead hazard warnings), and various safety concerns such as non-compliance with carbon monoxide and smoke alarm requirements, missing fire extinguishers, and stair repairs. These violations, however, were all abated by May 31, 2016.

The building's history includes regular routine inspections by Housing Inspection Services from 1999 through 2019, with a sewage leak incident reported and resolved in 1998, and an earlier building code compliance requirement in 1987. More recently, in 2020-2023, there have been various 311 calls related to the property, including construction noise, medical waste cleanup, and utility excavation issues, though these are primarily external to the building itself. The property has experienced one documented fire-related incident, which was recorded as a false alarm or call. The building's maintenance history shows attention to electrical infrastructure, as evidenced by the recent panel replacement, while past violations indicate periods requiring focused compliance efforts to meet safety and maintenance standards.

Risk rating

How 1251-1255 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
59th percentile

Out of 1125 buildings in this neighborhood, 461 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 59.6%
Moderate concern 31.0%
Severe concern 9.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
