Initial analysis

The two-unit residential building at 140 Jersey Street in Noe Valley, owned by James P & Mary W Costello, is a 1923 flats/duplex structure that has undergone several maintenance and repair projects over the years. Most notably, significant improvements were made to the property in 2014-2015, including a $11,450 reroofing project in February 2014 and the replacement of a dry rot-affected deck and stairs at the rear of the building in January 2015, with particular attention given to the legality of the second-floor deck height requirements.

The property has experienced recurring issues with driveway blocking, evidenced by multiple parking enforcement calls between 2023-2024, though these cases were ultimately deemed invalid due to incomplete reporting information. More concerning is the current open status of a collapsed sidewalk defect reported in February 2023, which presents a potential safety hazard for residents and visitors. The area around the building has faced various parking and street maintenance challenges, as documented in several 311 calls between 2021-2024, including instances of sidewalk parking, abandoned vehicles, and street cleaning needs, though most of these issues were resolved through appropriate channels. The building's maintenance record suggests regular upkeep by the owners, particularly regarding structural safety issues, though the unresolved sidewalk defect remains a notable concern.

Risk rating

How 140 Jersey St'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.
