Initial analysis

The three-story, two-unit residential building at 1679-1681 Newcomb Avenue in the Bayview neighborhood, owned by Ying Sau Kwok, has a complex history spanning several decades. Built in 1946, this flats and duplex structure has undergone multiple renovations and faced various safety concerns. Most notably, in 2016, significant modifications were completed including the conversion of garage/storage space into living areas with a bedroom, living room, and half bath, accompanied by necessary electrical and plumbing work totaling $60,000. This period also saw the installation of new electrical systems and plumbing fixtures throughout the first floor. Previous violations and complaints reveal a pattern of maintenance and safety issues, particularly between 2002 and 2006, including serious plumbing problems with sewage backing up into the basement, mold and mildew concerns, and various interior surface violations that were ultimately abated by October 2006. More recent concerns include a 2017 complaint about unsafe gas line relocation and improper water heater placement, though this violation is listed as not active. The building has experienced two notable fire-related incidents - a gas leak and a building fire caused by equipment failure, though fortunately neither resulted in civilian injuries.

The property has undergone several infrastructure improvements over the years, including an underground service conversion with dual 200-amp meters completed in 2008, and various electrical and plumbing upgrades. Recent developments in the surrounding area, as evidenced by 311 calls, show ongoing urban environmental challenges including reports of debris, encampments, and parking issues, though these are municipal surface conditions rather than building-specific concerns. While the building's historical records show a trajectory of addressing various maintenance issues, the pattern of violations and complaints suggests that attention to building systems and compliance with safety standards has been a recurring need throughout its history.

Risk rating

How 1679-1681 Newcomb 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.
