Initial analysis

The two-story multi-family residential building at 331-333 5th Avenue, owned by Joseph Fong, was constructed in 1923 and contains three units. The property has undergone several significant infrastructure improvements over the past three decades, including recent electrical upgrades in August 2023 with the replacement of Federal Pacific panels, which is a notable safety enhancement considering the historical safety concerns associated with this brand of electrical panel. Previous permits indicate work such as scaffold installation in 2010 and sidewalk-related improvements in 2003, while a reroofing project from 1993 appears to have expired. The building has undergone two routine safety inspections by Housing Inspection Services in 2003 and 2016, though no active violations are noted.

The property has experienced recurring issues with graffiti, particularly between 2018-2019 when multiple incidents were reported, including offensive graffiti on both the building and surrounding structures. More recent environmental concerns include two instances of waste on or near the property in 2024, though one was determined to be on private property. The building's infrastructure was assessed for a missing side sewer vent cover in 2013, but city officials determined that the condition had already been addressed and required no further action. The property's location has seen several parking-related issues, with sidewalk parking violations reported in 2024 and 2022, though enforcement officers were unable to locate the offending vehicles in both instances. While the building has experienced periodic maintenance and safety inspections, there are no current open violations or safety concerns on record as of October 2023.

Risk rating

How 331-333 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, 1103 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.

Building size

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

Building age

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

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 64.8%
Moderate concern 20.4%
Severe concern 14.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
