Initial analysis

The four-unit multi-family residential building at 936-940 York Street in San Francisco's Inner Mission neighborhood is a three-story structure built in 1905, currently owned by Gwen E Terpstra 2020 Revoc. The property has undergone several significant maintenance events, including an electrical issue reported in 2021 and a routine safety inspection in 2015. In 2003, the building faced multiple violations including required repairs to stairs, installation of smoke detectors, and provision of fire extinguishers, all of which were addressed through a permit for dry rot repair of rear stairs valued at $2,000, and were officially abated by June 2009. A reroofing project was completed in 1997.

Recent maintenance and compliance history shows only minor issues have been reported, primarily concerning parking enforcement and street cleaning matters in the surrounding area, with several parking violations documented between 2019-2022. The most recent building-related service calls include a water-related issue in June 2024, and there was one recorded fire incident characterized as a "smoke scare, odor of smoke" with no civilian injuries. The building's overall record shows that while there were significant safety compliance issues in the early 2000s, these were addressed, and more recent complaints have been primarily related to external factors rather than building conditions or safety concerns.

Risk rating

How 936-940 York 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, 1761 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.

Neighborhood location

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

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

12-Month severity forecast
No violation 37.8%
Moderate concern 40.3%
Severe concern 21.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
