Initial analysis

The property at 165-169 2nd Avenue is a two-story, multi-family residential building constructed in 1902, currently owned by Yang Chi-kuo & Lee Chen Yan. The building contains 5 units and features both residential and retail space. Significant structural work was performed in 2003, including the replacement of existing wood floors due to dry rot with new foundation and slab installation costing $60,000. During the same period, accessibility improvements were made including the installation of an ADA-compliant toilet room, along with electrical work for office space. Two building permits from December 2006 were issued to renew previous permits for final inspection of the two buildings on the lot, and a gas houseline extension was completed in May 2007.

The building experienced several maintenance issues in the late 1990s, including water leakage problems between residential and commercial spaces, though these were resolved. More recent history shows a pattern of exterior maintenance and cleanliness issues, with multiple 311 calls in 2024 regarding garbage, debris, and general cleaning needs around the property. These cases, primarily related to street and sidewalk conditions, were generally resolved, though one general cleaning case from February 2024 remains open as of the latest update. A vertical addition permit application from 1997 appears to have expired without completion. The property underwent several interior modifications in 2003, including retail space remodeling with new partition walls and the installation of multiple electrical fixtures. Recent exterior modifications in 2003 included new windows installation, though this work reportedly occurred outside the approved commercial zoning designation.

Risk rating

How 165-169 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
27th percentile

Out of 660 buildings in this neighborhood, 482 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 63.6%
Moderate concern 18.7%
Severe concern 17.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
