Initial analysis

The property at 302-304 23rd Avenue, located in San Francisco's Central Richmond neighborhood, is a two-story multi-family residential building with three units and ground-floor commercial space, constructed in 1911. The building has undergone several significant improvements over the past decade, with the most recent work being the replacement of the primary entrance door in December 2023 to comply with ABE requirements, following a 2022 permit application. Prior major renovations include a complete reroofing in 2016 ($20,000), replacement of 13 second-floor windows in 2015 ($11,000), and a comprehensive kitchen and bathroom remodeling project in Unit 302 in 2015 ($25,000) that included plumbing and electrical upgrades. The building experienced a compliance issue in 2009 when an awning was installed without a permit, leading to a notice of violation that was eventually resolved in 2012.

Recent developments at the property include multiple 311 calls regarding street cleaning and sidewalk maintenance in 2022-2025, with reports of garbage, debris, and abandoned items near the property, though these external issues don't necessarily reflect on the building's internal conditions. A commercial space was reported as vacant in October 2022, and there were historical complaints about water pipe noise (1998) and a broken back door (1995), though these issues were resolved. The current owners, Roland & Janine Jung 2007 F, have maintained the property through regular upkeep and compliance with city regulations, as evidenced by the recent completion of required door modifications and previous major structural and aesthetic improvements. The building's maintenance history suggests ongoing attention to both residential and commercial components, with particular focus on updating windows, roofing, and compliance with building codes.

Risk rating

How 302-304 23Rd 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.
