Initial analysis

The 4425 Balboa Street property is a three-story, five-unit multi-family residential building constructed in 1965, currently owned by the Matina L Polakis Trust. The building has undergone several significant improvements over the past few decades, including a $10,500 patio door replacement in 2016, a comprehensive kitchen remodel in Unit 5 in 2013 (involving new cabinets, sink, dishwasher, and electrical work), and window replacements in 2002. Historical records show the two notable fire safety incidents occurred in 2008 (with alarm systems) and 2006 (with a violation for exit obstruction/fire escape that was subsequently corrected), though no civilian injuries have been reported in any fire-related service calls.

Of particular concern are recent patterns of maintenance and safety-related issues. In 2023-2024, there have been numerous 311 calls regarding tree maintenance, including an incident of property damage by tree branches in December 2024. The property has experienced recurring issues with street cleaning and debris, with multiple reports between March and December 2024. While these primarily external maintenance issues may not directly impact unit residents, they suggest ongoing challenges with property upkeep in the surrounding area. The building's systems underwent periodic upgrades and maintenance throughout its history, though the 1993 roofing permit is listed as expired.

Risk rating

How 4425 Balboa 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

Out of 1040 buildings in this neighborhood, 863 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 60.0%
Moderate concern 15.0%
Severe concern 25.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
