Initial analysis

The property at 415-421 South Van Ness Ave is a 3-story multi-family residential building constructed in 1900, containing 6 units and currently owned by SST Investments LLC. The building underwent significant renovations in 2008, including electrical and plumbing upgrades, kitchen and bathroom remodeling across multiple units, with particular attention to units 415, 415A, 421, and 421A. This renovation work, valued at $80,000, included the installation of 4 heaters, a complete electrical system upgrade (including 50 lights, 60 switches, and 120 circuits), and gas line modifications. However, the building has experienced several concerning issues over the past decades, including a 2014 complaint about mold throughout the unit, and in 2006, there were reports of bathroom corrosion, rotting wood, black mold, and problems with building access and garbage management. A notable violation in January 2011 resulted in multiple safety requirements being addressed, including installation of smoke detectors, resolution of egress obstructions, and security improvements, all of which were abated by February 2011.

The building's history shows some structural and maintenance improvements, including a roof replacement in 2000 and stucco repairs in 1990. More recently, there have been several exterior maintenance issues documented through 311 calls, primarily concerning graffiti (notably in 2023), and environmental concerns including garbage issues. The property has experienced two fire-related incidents, though neither involved civilian injuries: one was for smoke/odor removal and the other for a malfunctioning CO detector. While the building has undergone substantial improvements in its systems and safety features, the history of maintenance issues and the age of the building suggest ongoing attention to building upkeep is necessary.

Risk rating

How 415-421 South Van Ness Ave'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.
