Initial analysis

The Wong Family Trust owns this two-story, four-unit multi-family residential building located at 266 24th Ave in the Lake-The Presidio neighborhood. Built in 1900, this flats and duplex style structure has undergone several maintenance and upgrade projects over the years, with the most significant recent work being a $21,000 reroofing project completed in 2022. Other notable improvements include the installation of seven vinyl windows in 2004, replacing older windows with no structural changes, and a previous roofing project from 1996, though that permit has since expired.

The property has experienced recurring issues with street cleaning and waste management in recent years, particularly between 2023 and 2024, with multiple reports of loose garbage and debris, including incidents involving furniture on the street. Of particular concern is a sewage backup incident reported in November 2023, which required intervention from PUC Sewer Operations and was eventually resolved. While the building's structural maintenance appears to be generally addressed through periodic updates, the surrounding area has faced persistent challenges with street cleanliness, as evidenced by the multiple 311 calls for general cleaning and garbage issues. The most recent service requests include a faded street cleaning sign (February 2024) and an overgrown tree pruning request (February 2023), both of which have been resolved.

Risk rating

How 266 24Th 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
42th percentile

Out of 660 buildings in this neighborhood, 383 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.

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 79.5%
Moderate concern 15.2%
Severe concern 5.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
