Initial analysis

The two-unit residential building at 1779-1781 Newcomb Avenue in Bayview, owned by Joseph J Yee, is a two-story flats and duplex structure built in 1912. The property has undergone several significant improvements over the past decades, including the installation of a 1.2 kW solar PV system with six roof-mounted panels in 2012 and the conversion of PG&E service from overhead to underground in 2006. Two roofing projects have been documented: one completed in 2010 at a cost of $6,000, and a more recent permit filed in December 2024, though the cost is listed as $0.

The building's exterior and surrounding area have experienced recurring maintenance challenges, particularly with sidewalk conditions and waste management. There have been multiple reports of garbage and debris on the street between 2022 and 2024, with the most recent incidents occurring in October and December 2024. Sidewalk defects have been noted in both September 2023 and September 2022, with one case involving removed scaffolding that was documented during inspection. The property is generally maintained according to records, though the frequency of street cleaning issues suggests ongoing environmental challenges in the immediate vicinity. A historical tenant buyout occurred at a neighboring address (1783 Newcomb Avenue) in January 2017, involving two tenants and a payment of $35,950, though this is not directly related to the subject property.

Risk rating

How 1779-1781 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.

Neighborhood percentile

Out of 382 buildings in this neighborhood, 130 are predicted to be safer.
