Initial analysis

The 3342-3344 Laguna Street property is a two-story, three-unit multi-family residential building located in San Francisco's Marina neighborhood. Built in 1927 and currently owned by the Yang Family 2004 Trust, this apartment building has undergone several significant renovations and faced various maintenance challenges over the years. The most recent major renovation occurred in 2019, when all three units received comprehensive upgrades including kitchen and bathroom remodels, wall reconfigurations, and the addition of fireplaces. This renovation also included significant infrastructure improvements such as new gas high-efficiency furnaces on all floors, complete plumbing upgrades including new sewer pipes, water service, gas line installations, and electrical system improvements.

The building has experienced recurring fire safety compliance issues, with the most recent fire inspection violation occurring in November 2023 regarding extinguishers that has since been abated. Historical fire safety concerns include sprinkler system violations in 2019 (abated), alarm system issues in 2019 (no merit), and several other fire-related complaints between 2018 and 2007 that were either corrected or found to have no merit. The property has required various maintenance work over the years, including dry rot repairs in 2007, wall and floor framing repairs in 2005, and a new roof installation in 1992. More recent history shows the building has experienced periodic issues with street cleanliness and garbage management, as evidenced by multiple 311 calls between 2023 and 2025. The property has also faced some infrastructure challenges, with heating system work requiring recommencement in 2021 and various permits showing some work remaining incomplete or requiring follow-up actions. Regular tree maintenance requests and parking enforcement issues have been noted in recent years, reflecting typical urban maintenance concerns for the area.

Risk rating

How 3342-3344 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.
