Initial analysis

The three-story multi-family residential building at 939-941 Shotwell Street in the Inner Mission, owned by Hernandez Balmore J & Sandr, consists of 7 units and was constructed in 1960. The property has a documented history of maintenance and safety compliance issues, most significantly a series of violations identified during a routine inspection in October 2015 that were not abated until May 2016. These violations included requirements for smoke detectors, handrails, carbon monoxide alarms, and other safety features in common areas. The building underwent several renovation projects between 2005-2006, including repairs from fire damage in 2005, plumbing and electrical upgrades, and interior modifications. A more recent complaint from October 2018 reported problems with a rear bedroom window in unit 941 that wouldn't close properly, causing draft issues.

The property has maintained an active maintenance record, with various repairs and improvements documented through building and electrical permits. Regular safety inspections have been conducted, including an annual routine inspection in 2015 that revealed multiple safety code violations requiring correction. Recent records from 2024 show various municipal service calls near the property, including reports of debris, tree damage, and sewage issues, though these were primarily related to street conditions and not the building itself. A single fire incident is noted in the records, involving a smoke detector activation due to malfunction, with no civilian injuries reported. The most recent building complaints suggest ongoing attention to maintenance and safety compliance, though there is no record of any serious safety incidents since the 2015 violations were addressed.

Risk rating

How 939-941 Shotwell 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, 1928 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.

Number of units

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

Property class

The assessor's property-class code, which correlates with building type and the violation rates the model expects. This code is grouped with other less-common classes.

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 28.6%
Moderate concern 32.0%
Severe concern 39.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
