Initial analysis

This 1924 two-story multi-family residential building located at 318-320 Harriet Street in the South of Market neighborhood, owned by Georgia B Stewart, is a flats and duplex structure containing two units. The building underwent significant renovations in early 2005, including the construction of new bathrooms on each floor, kitchen remodeling, and water heater relocation to the ground floor, with associated electrical work totaling approximately $64,000. More recently, in late 2024, there was a complaint about unauthorized work involving scaffolding and asbestos tile removal, though this was resolved by mid-January 2025. The building has experienced several maintenance and environmental challenges in 2024, including a sewage backup discharge from the side sewer vent in July, multiple instances of garbage and debris on and around the property, and several reports of blocked driveways. There were also two encampment-related incidents in mid-2024 near the property. While the building's fire alarm system has experienced several unintentional activations and malfunctions over the years, there have been no reported civilian injuries associated with these incidents. Historical maintenance records show past work including reroofing in 2001 and replacement of rear stairs in 1989, indicating ongoing property upkeep.

Risk rating

How 318-320 Harriet 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.
