Initial analysis

The property at 1790 Newcomb Avenue is a 1-story, 2-unit multi-family residential building constructed in 1930, currently owned by Nwihim Adolphus C N & Nwihi. The building has experienced several significant issues over the past two decades, with the most recent notable complaint regarding unpermitted work filed in December 2019. In 2015, there was a complaint about inadequate heating, and in 2010, multiple housing code violations were documented, including electrical problems with plugs, switches, and outlets, as well as issues with a washing machine and an oven. These 2010 violations prompted several corrective actions, including the installation of new electrical components (plugs, lighting, smoke detector) and a non-structural partition wall to create an additional bedroom, with work valued at $1,000. Earlier issues include plumbing problems in 2009 involving a sink repair, and in 1998, there were water leakage problems that were documented and resolved.

The building's infrastructure has seen some updates, including a PG&E conversion from overhead to underground service in 2005 (permit expired) and a roofing project completed in 1998 (permit expired). More recent maintenance concerns have primarily involved external issues, as evidenced by multiple 311 calls between 2018-2022 regarding sewer odors, pavement defects, and street cleaning matters. While these external maintenance issues have been addressed and closed, they are separate from the building's internal systems. The property has undergone various inspections and received multiple violation notices, all of which have been marked as not active after being abated, suggesting that the major historical compliance issues have been resolved, though the more recent complaints about unpermitted work and inadequate heat remain notable on the record.

Risk rating

How 1790 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
