Initial analysis

The 17-unit, 5-story apartment building at 140 Gardenside Drive, managed by the Alan & Jenny Tan Family Trust, has undergone several significant safety and structural improvements since its construction in 1975. Most recently, in January 2025, the building received a fire alarm system upgrade costing $65,175 to comply with current fire code requirements, including the installation of new monitoring equipment and safety features. The building completed its mandatory soft-story seismic retrofit in 2015, which included adding steel framing to improve structural integrity. Historical records show recurring water-related issues, with multiple repairs documented between 2003-2006 addressing leaks in balconies, exterior walls, and bathroom areas, though some moisture-related problems persisted, including mold issues reported in 2002 and 2012.

The building has a documented history of fire safety concerns, with violations and complaints regarding alarm systems, exit maintenance, and sprinkler systems recorded between 2018-2023. A recent violation (December 2023) regarding sleeping area requirements is currently open. While there have been several false alarms and system malfunctions recorded in the past, no civilian injuries have been reported in any fire-related incidents. The property has also experienced periodic maintenance challenges, including interior surface repairs, damaged walls and ceilings, and security concerns like a non-functional intercom system (2005-2012). The building's management has generally addressed violations and complaints within reasonable timeframes, with most historical issues being marked as resolved or abated. Recent years have seen ongoing attention to fire system maintenance, as evidenced by the completed 2025 fire alarm system upgrade.

Risk rating

How 140 Gardenside Dr'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
34th percentile

Out of 172 buildings in this neighborhood, 114 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 size

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 36.7%
Moderate concern 34.1%
Severe concern 29.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
