Located in San Francisco's South of Market neighborhood, the 321-323 10th Street property is a two-unit, two-story multi-family residential building with a ground-floor commercial space, built in 1906 and currently owned by Downtown San Francisco Prop. The building has undergone significant improvements over recent years, with major renovations occurring between 2017-2019. These include a substantial ground floor remodel with seismic upgrades ($250,000), second-floor kitchen renovations ($16,000), and a conversion of a rear accessory structure into a design professional office space with ADA compliance features ($200,000).

Recent maintenance and security issues have been documented through 311 calls, primarily related to external matters such as cleaning needs, graffiti incidents, and sidewalk conditions, with the most recent calls in August 2024. While these external issues have been generally resolved, they indicate ongoing urban maintenance challenges in the surrounding area. The property's historical preservation status is noted on planning records, with particular attention to the rear accessory structure's historical significance during recent renovation planning. The building's recent improvements have focused on modernization and safety upgrades, including new utilities, seismic improvements, and accessibility features, though the property has maintained its historical facade requirements as stipulated in planning records.

Risk rating

How 321-323 10Th 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.
