Initial analysis

The 7-unit multi-family residential building at 223-225 25th Avenue in the Lake-Presidio neighborhood, owned by John Y C & Eva L Tang Living Trust, has a documented history dating back to 1986 when the original apartments were demolished and the current structure was completed in 1988. The building has experienced several significant maintenance and safety issues over the years, most notably in December 2016 when multiple violations were recorded including problems with the central alarm system, damaged ceilings, and concerns that led to the property being designated as a "nuisance" under Section 1001-d of the San Francisco Housing Code. These violations were officially abated by March 2017. More recent concerns include an active complaint from May 2017 regarding a potentially hazardous dryer vent pipe on the property, though the current status of this issue is unclear based on available records.

The property has maintained some level of upkeep, including a reroofing project in 2011 valued at $9,300, and there are no active building violations as of now. However, there is a pattern of fire safety and alarm system issues, with documented problems in 2002, 2014, and 2016 regarding fire alarms and smoke detection systems. The building's parking and surrounding area has experienced numerous issues with abandoned vehicles and parking violations in recent years, particularly in 2022. Multiple 311 calls in 2023-2024 have been primarily related to parking concerns around the property, though these are not directly related to building conditions. A tree root issue affecting the sidewalk was reported in April 2022 and remains open.

Risk rating

How 223-225 25Th 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 660 buildings in this neighborhood, 521 are predicted to be safer.

Model explanation

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.

Moderate concern 22.3%
Severe concern 16.3%
