Initial analysis

The 3350-3354 16th Street property is a 6-unit, 3-story multi-family residential building constructed in 1905, currently owned by Raul & Valerie A Arriaza. The building has undergone several significant safety improvements in recent years, most notably completing a mandated soft-story retrofit in 2022 at a cost of $60,000, bringing the building into compliance with seismic safety requirements. In 2022, the building addressed dry rot issues at the front facade following a notice of violation. A recent complaint from May 2024 reported black mold in the garage area, along with concerns about water damage and leak issues, though this complaint has since been marked as not active. The building has a history of routine inspections, with a notable cluster of violations recorded in 2002 related to safety systems and building maintenance, including requirements for smoke enclosure doors, adequate lighting, fire extinguishers, and security features; all these violations were abated by November 2002. Earlier building improvements include fire safety upgrades in 1995 (fireproofing rear windows) and roofing work in 1996. The property has maintained its soft-story retrofit compliance status (Tier 3, Work Complete, CFC Issued) since 2022, following an earlier failed attempt to complete this work in 2017. Recent external maintenance issues have been documented through multiple 311 calls in 2024, primarily related to street cleaning and debris removal, including reports of human waste and graffiti near the property, though these issues are more related to public space management than building conditions.

Risk rating

How 3350-3354 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.

Neighborhood percentile
