Initial analysis

The two-unit multi-family residential building at 368 31st Ave in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1912, currently owned by the To/tseung Family Trust. The building has undergone several significant improvements over its lifetime, with the most recent major work being a $15,300 reroofing project completed in 2021. Historical permit records from the early 1990s show prior modifications related to a swimming pool, including bathroom and changing room installations and additional stairways, though these permits are now marked as expired. An earlier renovation from 1990 involving vertical and horizontal additions was completed.

Recent activity around the property has been primarily related to street conditions and parking issues, with multiple parking enforcement requests in 2024 regarding driveway blockages and illegal parking, resulting in at least one citation being issued. The surrounding area has experienced recurring issues with waste management, as evidenced by two reports of human or animal waste on nearby streets or sidewalks in September 2023. Park maintenance matters were addressed in 2023, including structural maintenance of recreational equipment and replacement of damaged property, though these are related to the adjacent park rather than the building itself. The most recent urban infrastructure issue was an incorrect sign placement reported and resolved in January 2024.

Risk rating

How 368 31St Ave'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 2250 buildings in this neighborhood, 450 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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 74.5%
Moderate concern 20.6%
Severe concern 5.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
