Initial analysis

The four-story, three-unit multi-family residential building at 107 28th Street in Noe Valley, owned by the Natenson Family Trust, was built in 1921 and has a documented history of regulatory compliance issues requiring attention to safety systems. Most recently, in early 2023, the property was cited for not submitting required smoke/carbon monoxide detector compliance and Section 604 compliance affidavits, though these violations were abated by May 2023. A related inspection in February 2023 found no violations, but noted that compliance affidavits were due. Looking further back, the building had fire safety violations in September 2006 for combustibles stored under stairs and exit obstructions, both of which were subsequently closed.

The property's external environment has experienced several parking-related incidents over the years, with documented cases of driveway blocking in 2024, 2020, and 2019, all of which were resolved through parking enforcement. In 2019, there was also a noted issue with construction equipment blocking a parking space, which resulted in a citation for not maintaining a valid sidewalk permit and proper path of travel. A general building inspection request was filed in October 2014, though specific details about the outcome are not provided in the records. While the property has had various compliance issues requiring attention, it's worth noting that these violations were generally addressed and closed out, with the most recent being resolved within three months of citation.

Risk rating

How 107 28Th 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
22th percentile

Out of 1879 buildings in this neighborhood, 1466 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.

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

Building age

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

12-Month severity forecast
No violation 45.7%
Moderate concern 43.7%
Severe concern 10.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
