Initial analysis

The two-unit multi-family residential building at 3231-3233 Laguna Street in San Francisco's Marina neighborhood, built in 1906 and currently owned by the Lillian C Tom Trust, has undergone several significant maintenance events over its history. The building received a complete reroofing in 2001 (cost: $4,800) and had its water service pipe replaced in 2016, representing the most recent major infrastructure update. There was a building permit application in 2009 to replace three windows (two in the rear and one at the side facade) valued at $1,500, though this permit was ultimately cancelled. A notable housing inspection complaint was filed in 1997 regarding multiple unit issues including non-functional heating, peeling paint and wallpaper, sporadic lighting, and bathroom problems, which remained active until resolution in 2009.

The property has recently experienced ongoing challenges with street conditions and public space maintenance, particularly in late 2024 and early 2025, with multiple reports of encampments and sanitation issues in the immediate vicinity. Between November 2024 and January 2025, there were several instances of reported encampments and cases requiring street cleaning due to human waste or urine, with some cases remaining open or in progress as of the latest reports. A building inspection complaint was filed in early January 2025, though details of the resolution were not specified. The building has also had three emergency responses in recent years (two police matters and one emergency medical service incident), none involving civilian injuries. The property's maintenance history shows some attention to basic infrastructure upkeep over the years, though the recent concentration of street-related issues near the property warrants noting as a current environmental context.

Risk rating

How 3231-3233 Laguna 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.
