Initial analysis

This two-story, multi-family residential building located at 4441 Balboa Street in San Francisco's Outer Richmond neighborhood was built in 1948 and contains 4 units, currently owned by Lam Collin & Wong Kimberley. The property has undergone several significant repairs and renovations over the past decade, including a substantial restoration in 2013 following fire damage that cost over $62,000, which included work on two apartment units' bathrooms and hallways, along with electrical and plumbing updates. More recent maintenance includes stair and railing repairs in 2018 to address dry rot issues, and in 2014 a bathroom remodel was attempted in unit #2.

The building has experienced some concerning issues over its recent history, particularly in 2014 when multiple complaints were filed regarding electrical problems, inadequate ventilation, discolored water, and mold. A 2019 complaint regarding an illegal unit modification was filed but marked as not active. The property has also faced regulatory challenges, with violations recorded in 2000 related to fire safety and security requirements, including needs for fire extinguisher maintenance and self-closing exterior doors, though these were abated by December 2000. Various maintenance records show attention to structural issues, including multiple instances of dry rot repair (1990 and 2018), reroofing projects (1990 and 2011), and compliance updates (1984). While there have been several 311 calls regarding the property and its surroundings in recent years, these have generally related to external street issues rather than building-specific problems.

Risk rating

How 4441 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, 926 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.

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.

12-Month severity forecast
No violation 49.8%
Moderate concern 22.7%
Severe concern 27.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
