Initial analysis

The two-unit residential building at 154 San Carlos Street in the Inner Mission, owned by Tang Wai Fong&danny M& Mari, has a documented history of maintenance and safety issues spanning several decades. Built in 1915, this two-story flats and duplex structure has experienced multiple significant problems, particularly evident in the period from 2005 to 2009, when numerous violations were recorded, all of which were ultimately abated in April 2009. These violations included urgent safety concerns such as damaged stairs, fire safety issues including combustible storage, lead paint hazards, plumbing problems, and various interior surface deficiencies. In 2016, another concerning complaint was filed regarding a deteriorating rear deck, though this was marked as not active.

More recently, from late 2023 through 2024, there have been numerous reports related to garbage and debris around the property, with multiple cases of loose garbage documented between November 2023 and November 2024. Two specific sanitation issues were highlighted, including human waste or urine reported in July 2024, which required attention to a property's drainage-related safety concern. The most recent building-related complaint in 2024 involved parking violations on the sidewalk, which resulted in a citation. The building's maintenance history includes some remedial work, such as a 2006 permit for stair repairs in response to a 2005 complaint, indicating some level of responsiveness to safety issues, though many problems persisted through the late 2000s. A building fire incident was also recorded, though it occurred under circumstances categorized as "Unintentional" with no civilian injuries reported.

Risk rating

How 154 San Carlos 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 2380 buildings in this neighborhood, 476 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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 74.4%
Moderate concern 15.2%
Severe concern 10.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
