Initial analysis

The 9-unit, 2-story multi-family residential building at 2400 39th Avenue in the Outer Parkside neighborhood, built in 1957 and owned by the Kee Koon Yee Mui Trust, has undergone several significant maintenance and safety improvements over the past two decades. Most notably, the building completed its mandatory soft story seismic retrofit in 2017 at a cost of $49,000, demonstrating compliance with San Francisco's important seismic safety requirements. Other major structural work included a 2012 repair project addressing dry rot in deck framing, support column replacements, and various concrete, tile, and stucco repairs at a cost of $20,000, as well as a reroofing project completed in 2003. The building has maintained regular inspections by Housing Inspection Services, with notable fire safety compliance issues being promptly addressed, including recent inspections in 2024 and 2022 related to fire extinguishers and exit maintenance.

In recent months (2024), there have been multiple reports of parking-related issues near the property, including several cases of blocked driveways and illegal parking, though these are often quickly addressed by enforcement officers. The building generated a routine housing complaint in 2001 and 2003, both of which were resolved. While there have been some service-related incidents noted in 311 calls, such as a missing side sewer vent cover and various street cleaning matters, these do not directly impact the building's habitability. The property's fire safety record shows consistent attention to maintaining fire extinguishers, with the most recent issue being resolved in October 2024. The building's overall maintenance history suggests regular oversight and remediation of identified issues, with all major structural and safety concerns being addressed in a timely manner.

Risk rating

How 2400 39Th 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
3th percentile

Out of 207 buildings in this neighborhood, 201 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.

Neighborhood location

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

Building size

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

12-Month severity forecast
No violation 10.3%
Moderate concern 23.3%
Severe concern 66.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
