Initial analysis

The three-story, five-unit multi-family residential building at 28 Himmelmann Place in Nob Hill, owned by the May S W Young Grantor Trust, was constructed in 1900 and has undergone several significant maintenance and safety-related activities over the years. The building has received attention to its basic infrastructure, including reroofing work in both 1990 and 2011 (the latter costing $7,500) and exterior wall insulation installation in 1987. A series of safety violations and complaints in 2016 highlighted multiple concerns that were subsequently addressed, including the need for handrails, smoke detectors, carbon monoxide alarms, and removal of egress obstructions from back stairs. Earlier violations from 2000 regarding self-closing devices at exterior doors and smoke enclosure door closers were also resolved.

The most recent activity related to this property was a complaint in July 2024 regarding unpermitted exterior work starting early in the morning, which was resolved by early August 2024. Housing inspectors conducted regular routine inspections in 2000, 2008, and 2016, indicating ongoing monitoring of the building's compliance with housing codes. A series of 311 calls from 2020 to 2024 have primarily related to external conditions around the building, including sidewalk cleaning, debris issues, and street lighting concerns, with the most recent reports in October 2024 regarding garbage and debris. While the building has experienced various maintenance and safety issues over the years, records suggest that most violations have been addressed promptly, though the recent 2024 unpermitted work complaint indicates there may be occasional lapses in compliance.

Risk rating

How 28 Himmelmann Pl'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.

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.

Number of units

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

Building age

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

Neighborhood (ZIP code)

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

12-Month severity forecast
No violation 34.3%
Moderate concern 15.4%
Severe concern 50.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
