Initial analysis

311 Corbett Avenue is a two-story, 16-unit multi-family residential building located in San Francisco's Corona Heights neighborhood. Built in 1961 and owned by Survivors Trust, this property has undergone several significant renovations and improvements over the years. Most notably, the building completed its mandatory soft-story retrofit in 2022, which included the installation of steel moment frames to enhance seismic safety, with the final inspection and Certificate of Final Completion having been issued. The building has experienced recurring maintenance issues, particularly related to water damage, with multiple repairs for dry rot documented between 2003 and 2011, including work on exterior stairs, the 4th-floor deck, and garage areas. The property has also seen substantial sustainability improvements, including the installation of solar PV systems in 2008-2009 (102 modules), electrical vehicle charging infrastructure in 2013-2017, and new roof drains in 2011.

The building's history includes several building violations and complaints, though most have been resolved. These include a 2017 central alarm system issue and a 2013 complaint about soil migration affecting public sidewalks. Recent activity at the property, as evidenced by 311 calls between 2023-2024, has primarily concerned street cleaning issues outside the building, with multiple reports of medical waste and other debris on or near the property line. While these external maintenance matters have been promptly addressed by city services, they represent ongoing challenges in the immediate vicinity of the building. The property's maintenance record shows regular upkeep and compliance with major safety requirements, particularly with the recent completion of the soft-story retrofit program, though there have been periods requiring follow-up inspections and final approvals for various systems and improvements.

Risk rating

How 311 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
