Initial analysis

733 5th Avenue is a two-story, 6-unit multi-family residential building located in San Francisco's Inner Richmond neighborhood. Built in 1964 and currently owned by Mai John Jian Zhen & Mei Yi, the property has experienced several notable events over its history. The building's most significant cluster of issues occurred in 2003-2004, when multiple violations were documented regarding safety systems, including problems with emergency exits, smoke detectors, and the central alarm system. Water damage in the lobby area was also noted during this period, along with maintenance and safety concerns affecting individual units. These violations were all officially abated by April 15, 2003.

Since the mid-2000s, the building has undergone routine safety inspections in 2003 and 2015, with no major violations recorded. More recent history shows several 311 calls related to the property, primarily concerning parking violations and sidewalk issues, though these are not directly related to the building's condition. In 2017, the property experienced two consecutive sewage backup incidents that were resolved by the Public Utilities Commission. The building has also had several fire alarm activations recorded between 2003 and 2020, all of which were either false alarms or related to system malfunctions, with no injuries reported in any incident. The most recent service-related interaction occurred in January 2024, but this was not directly related to the building's condition or systems.

Risk rating

How 733 5Th 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 1723 buildings in this neighborhood, 1051 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

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 69.2%
Moderate concern 12.8%
Severe concern 18.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
