Initial analysis

The two-story, six-unit multi-family residential building at 333 9th Avenue in the Inner Richmond, built in 1965 and owned by Tat Man & Sharon W Cheung R, has undergone several significant safety and maintenance improvements over the years. Most notably, in 2017, the building completed a mandatory seismic retrofit of its soft-story structure at a cost of $96,000, demonstrating compliance with SFBC Chapter 4D and Maher Ordinance requirements. The property has maintained active compliance with safety regulations, addressing multiple violations from a 2016 routine inspection that included the installation of carbon monoxide detectors, proper hot water heater flue pipe slope, and posting of gas meter instructions. While there was an unpermitted construction complaint filed in March 2017, this was subsequently marked as not active. Historical maintenance includes repairs to wood and stucco in 2008 and reroofing work in 2001.

Recent activity around the property has primarily involved external issues, with multiple 311 calls in 2024 regarding garbage and debris on adjacent streets, including recurring reports of overflowing city garbage cans. The most recent complaint, filed in September 2024, pertained to building damage and remains open as of October 2023. The building has had regular housing inspections over the years, including routine checks in 2001, 2009, and 2016, with most violations promptly addressed and resolved. A fire-related incident occurred in 2023, recorded as a false alarm with no civilian injuries. The property's compliance with seismic retrofitting requirements and prompt response to safety violations reflects active management of building maintenance and safety standards.

Risk rating

How 333 9Th 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
44th percentile

Out of 1723 buildings in this neighborhood, 965 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.

DBI complaints, owner's portfolio

Complaints across all of this owner's buildings over 7 years.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 81.2%
Moderate concern 13.2%
Severe concern 5.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
