Initial analysis

The property at 3339-3349 23rd Street in San Francisco's Inner Mission is a two-story mixed-use building constructed in 1900, containing 3 residential units and ground-level commercial space. The building has undergone significant recent improvements, particularly in 2021, including accessibility upgrades to the bathroom and entrance, kitchen renovations with new equipment and water heater installations, and comprehensive electrical work. These improvements were part of an effort to address previous building complaints and compliance issues, including a vacant storefront violation from July 2020 that was resolved by July 2021.

The building's history reveals some concerning periods, particularly in 2020-2021, when multiple complaints were filed regarding the property's condition, including reports of vacancy, disrepair, pest issues, and maintenance neglect. These were eventually addressed through the 2021 renovations. Earlier records show various maintenance activities, including a 2008 kitchen fire system upgrade and wall repairs due to charred framing. Recent plumbing work has included the installation of new bathroom fixtures and floor drains, along with the addition of a grease trap in 2013. The property has faced some ongoing challenges with exterior maintenance as evidenced by multiple 311 calls regarding street cleaning and debris removal throughout 2024, though these are primarily related to surrounding public spaces rather than the building itself. The ground-floor commercial space has received permits for restaurant use, including limited live performance and outdoor amplified sound approval, indicating an active business component to the property.

Risk rating

How 3339-3349 23Rd 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.
