Initial analysis

The property at 4352 25th Street is a two-unit, two-story multi-family residential building located in Noe Valley, constructed in 1910. The building is currently owned by the Jerry B Polon 89 Rev Liv Trust and has undergone several documented improvements over the years. In 2012, the property received significant upgrades including the installation of four energy-efficient windows with a U-value of 0.29, and work was initiated to install a new 1-inch copper water main from the meter to the water heater in the basement, though this plumbing permit ultimately expired without confirmation of completion.

The building has generated several 311 calls between 2015 and 2021, primarily related to neighborhood maintenance issues rather than building-specific problems. These calls included reports of street cleaning and waste management concerns, with incidents involving misscheduled toter placement and vehicle-related complaints. Three abandoned vehicle reports were filed between 2015 and 2016, though in each case, the vehicles were gone upon inspection. The most recent incident on record was in March 2021 regarding a vehicle parked on the sidewalk, which resulted in a police response but no violation was found. While these neighborhood issues have been addressed through outreach and enforcement, they appear to be more reflective of street-level concerns rather than building-specific problems. The property has maintained a relatively low frequency of documented issues, with most building improvements being proactive upgrades rather than reactive maintenance.

Risk rating

How 4352 25Th St'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
74th percentile

Out of 1879 buildings in this neighborhood, 489 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.

Neighborhood location

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Construction spend, owner's portfolio

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

12-Month severity forecast
No violation 70.6%
Moderate concern 14.7%
Severe concern 14.7%
