Initial analysis

The three-unit residential building at 620-622 Natoma Street in the South of Market neighborhood, owned by Michael Joseph Smith, is a three-story structure built in 1912. The property has undergone several significant recent improvements, including a comprehensive electrical system upgrade in August 2023 involving the installation of a new 400-amp electrical service with four meters and panels, as well as kitchen and plumbing renovations. A kitchen remodel was completed in September 2022, featuring new electrical wiring for various appliances and fixtures. However, there have been some concerning recent issues, including a construction-related complaint in January 2024 regarding sewage disposal, and multiple 311 calls in 2024 related to sanitation issues in the vicinity, including reports of human waste and garbage on the street.

The building has a history of addressing safety concerns, with four fire safety violations recorded in September 2007 requiring the installation of fire extinguishers and resolution of combustible storage issues, all of which were abated by October 2007. Earlier maintenance issues from 2005 included concerns about water leaks, door problems, and pest control, which were also addressed. The property has documented two gas-related incidents (one involving a gas leak and another related to CO detector activation) responding with no civilian injuries recorded. While there have been some expired permits from the 1980s in the records, these appear to be unrelated to current conditions. Recent activity has shown regular maintenance and upgrading of building systems, though the recent construction-related complaint and ongoing sanitation issues in the area may warrant attention.

Risk rating

How 620-622 Natoma 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.
