Initial analysis

The building at 20-26 Commer Court in Bayview, owned by Bayview Preservation LP, is a multi-family residential property constructed in 1976. The building has undergone several significant renovations and maintenance projects over the years, with the most recent work in 2024 including interior unit upgrades valued at $550,000 (covering kitchen and bathroom renovations, flooring, and doors) and a $74,880 roof replacement. The property has experienced multiple maintenance issues in the past, particularly in 2019 when there were complaints about a non-functioning heater, plumbing problems, and rodent infestation. Historical records show recurring plumbing issues, including sewer repairs in 2013 and various complaints about water-related problems between 2013-2019. In 2007-2008, substantial improvements were made through Aimco, including electrical system upgrades, installation of new fixtures, and other renovations worth over $674,000.

The building has undergone various inspections and faced multiple violations over its history, though these have been resolved. Notable past violations included concerns about interior surfaces, damaged ceilings, and various miscellaneous issues in 2002, followed by more recent issues in 2019 regarding floor covering, closet doors, walls, and a heater. The property has experienced some infrastructure challenges, with documented plumbing failures causing water issues in 2013 and evidence of vermin problems in multiple years. More recently, there have been several external maintenance calls recorded in late 2024 regarding sidewalk conditions, debris, and graffiti, though these appear to be routine external maintenance issues. While the building has faced various challenges over the years, the recent pattern of significant investment in upgrades and maintenance suggests ongoing efforts to improve and maintain the property, with most historical violations being properly abated through appropriate corrective actions.

Risk rating

How 20-26 Commer Ct'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.

Grade C — Moderate risk

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
