Initial analysis

The two-unit, two-story multi-family residential building at 579 2nd Avenue in the Inner Richmond, owned by Yung Kwong Chung & Fung Wai, has a documented history dating back to its 1903 construction. The most significant recent concern involves an active building complaint from September 2018 regarding unauthorized construction work on the back of the building, including wall movement, porch enclosure, and stair rebuilding, which was reported to be conducted in a dangerous manner without proper permits. This complaint coincided with a permitted project for door replacement and painting that same month, suggesting potential discrepancies in construction activity. The building underwent several documented improvements in 1996, including wall repairs, bathroom and kitchen remodeling on the ground floor, window replacements, and cement repairs in the basement, though all these permits have since expired.

More recent issues near the property have primarily involved parking violations, with two incidents of sidewalk parking reported in 2021 and 2023, though these could not be fully validated by responding officers. An earlier infrastructure concern was noted in 2014 regarding sidewalk defects, specifically in relation to cracking and damage, which was officially addressed through the necessary channels. While the building's permit history shows some attention to maintenance and improvements, the most pressing concern remains the active complaint from 2018 regarding unauthorized construction work and potential safety hazards.

Risk rating

How 579 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

Out of 1723 buildings in this neighborhood, 414 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 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 78.8%
Moderate concern 13.9%
Severe concern 7.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
