Initial analysis

The 797 Corbett Avenue property is a 2-story, 7-unit multi-family residential building constructed in 1950 and currently owned by Grossman Family Partnership. The building has undergone several significant renovations and repairs over the past decade, with the most critical being a mandatory seismic retrofit completed in 2016 (as a Tier 3 soft-story building) at a cost of $90,000. Water damage issues emerged in mid-2019, affecting the entry walkway/porch areas of units #2 and #3, leading to multiple repair permits and violations that were eventually resolved by September 2022. The building has received regular maintenance, including a complete reroofing in 2010 ($39,485), various unit remodels between 2013-2014 (including kitchen renovations in units 1 and 7), and multiple deck repairs. A sewer trap replacement was completed in July 2022, indicating attention to plumbing infrastructure.

The property has experienced three documented fire-related incidents, including one building fire (equipment failure, no injuries) and two cooking-related incidents, none resulting in civilian injuries. Recent maintenance issues have primarily involved the exterior, with permits for walkway/deck repairs and dry rot remediation in 2019-2020 totaling $13,000. While the building has had several complaints and violations over the years, most have been resolved, including a notable 2019 complaint about unpermitted garage door replacements which was addressed through proper permitting. The building's maintenance record shows regular attention to both mandatory safety improvements and general upkeep, though recent 311 calls from 2023-2024 suggest ongoing issues with street cleaning and parking violations in the vicinity of the property.

Risk rating

How 797 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 172 buildings in this neighborhood, 64 are predicted to be safer.
