Initial analysis

The property at 500-502 2nd Avenue in San Francisco's Inner Richmond district is a two-story, 5-unit multi-family residential building with ground-floor retail space, built in 1907 and currently owned by Hong Kuai Keong & Hung Yee. The building has undergone several significant improvements in recent years, including ADA compliance modifications in 2023 with new signage and a battery-operated doorbell, and foundation preservation work in 2022 involving cement grout injection on the east side of the property. Historical records show earlier improvements such as reroofing in 1998, skylight installation in 1984, and various code compliance updates in 1983.

The building has a documented history of routine safety inspections by Housing Inspection Services from 1999 to 2016, with previous concerning issues in the 1990s regarding improper heater ventilation and gas fumes entering living spaces, particularly during 1995-1996. A notable fire safety violation was recorded and resolved in 2010 concerning combustible storage. More recent maintenance issues have primarily involved exterior concerns, with multiple reports of garbage and debris on the property (2023-2024), though these are typically city-wide issues rather than building-specific problems. The property's most recent permits and planning records indicate compliance with accessibility requirements and other municipal regulations, suggesting proper maintenance and responsiveness to code requirements by current ownership.

Risk rating

How 500-502 2Nd 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
39th 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.

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 75.4%
Moderate concern 15.3%
Severe concern 9.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
