Initial analysis

The Narruhn Family Trust owns this two-unit, two-story multi-family residential building located at 2951-2953 21st Street in San Francisco's Inner Mission neighborhood. Built in 1900, this flats and duplex-style property has undergone several significant improvements over the years. Most recently, in 2019, a 3.8 kW solar PV system was successfully installed on the roof, demonstrating the property's commitment to renewable energy. Between 2009-2014, the building received substantial maintenance and upgrades including structural reinforcement with additional bolts and foundation work (2014), window replacements (2013), bathroom renovations including fixture replacements and electrical updates (2009), and reroofing (2007). The property has experienced multiple false alarms and detector activations (with no reported civilian injuries) between 2019-2021, including incidents of smoke detector activation, CO detector activation, and alarm system malfunctions, though these suggest more about the system's sensitivity than actual safety concerns.

The building has been actively managed regarding maintenance and compliance issues, with notable repairs including the remediation of notched floor joists in the bathroom (2009), and various other improvements. Recent activity from late 2024 suggests some neighborhood cleanliness challenges, with multiple reports of garbage and debris, though these appear to be street-level issues rather than problems directly related to the building itself. The property's maintenance record shows regular upkeep and improvements, with no major building code violations or serious safety incidents on record. The relatively high number of 311 calls in recent months primarily relates to street cleaning and parking issues, which are external to the building's operation and management.

Risk rating

How 2951-2953 21St 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, 357 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 location

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

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 69.1%
Moderate concern 17.8%
Severe concern 13.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
