Initial analysis

The three-unit, three-story multi-family residential building at 3344-3348 16th Street, owned by the Mar & Choy 2015 Family Trust, has undergone several significant maintenance and safety-related repairs since its construction in 1906. Most recently, in 2023, there was a tenant complaint regarding door functionality and structural concerns, though this issue was marked as not active. During 2022-2023, the building received various updates including stair railings replacement due to dry rot, water heater flue code compliance, and light fixture installation. The building's systems were notably modernized in 2017, with a 200-amp overhead service upgrade, installation of a new Rinnai direct vent heater, and replacement of 10 feet of cast iron piping on the building's exterior.

Historical records from the early 2000s show significant attention to safety compliance, including a cluster of violations in January 2001 related to handrails, roof deck, stairs, and lead paint hazards, which were resolved by April 2002. The building underwent various structural improvements during this period, including reroofing and vinyl siding application. In 2014, there were two fire alarm system-related complaints that were promptly corrected. More recent maintenance includes regular resolution of 311 calls regarding exterior issues such as graffiti and utility covers, with the most recent incidents occurring in late 2024. The building has maintained an active maintenance schedule, with all recent building, plumbing, and electrical permits marked as complete, suggesting ongoing attention to property upkeep and code compliance.

Risk rating

How 3344-3348 16Th 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.
