Initial analysis

The three-unit, three-story multi-family residential building at 310 Corbett Avenue, owned by Alexander Varshavsky, has experienced several significant events since its construction in 1962. Most notably, the property faced water-related challenges in recent years, including multiple complaints from 2013-2014 about persistent water runoff creating safety hazards on adjacent public walkways, and a rockslide incident in 2016 that required remediation work completed in 2017. The building has undergone various improvements and maintenance work, including a sewer repair in 2011, reroofing in 2005, and electrical system upgrades, though some permits have expired or been marked as incomplete. Historical records show the building faced multiple violations in the early 2000s, including security concerns regarding hollow core doors, fire safety issues related to combustible storage, and sanitation violations, all of which were eventually abated. The property has also been the subject of two planning records indicating discussions about potential alterations, including considerations for demolition and rebuilding or renovation of the three-unit building.

The building's maintenance history includes work on windows (1989), dryrot decks (1985), and a now-expired permit from 2001 to convert an illegal apartment into storage. Recent 311 calls from 2021-2024 have primarily concerned external issues such as abandoned vehicles, street cleaning, and utility maintenance, rather than building-specific concerns. While the property has experienced various maintenance and regulatory challenges over the years, most violations have been addressed and resolved, with no active building violations currently on record. The property appears to be functioning within standard parameters, though recent years have shown particular attention to water management issues both within and around the property.

Risk rating

How 310 Corbett 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.

Neighborhood percentile

Out of 348 buildings in this neighborhood, 230 are predicted to be safer.
