Initial analysis

The building at 586-588 23rd Avenue in the Central Richmond neighborhood is a two-unit, two-story multi-family residential property known as Mar Helen, constructed in 1925. The property has undergone several significant improvements over its lifetime, with the most substantial renovations occurring in 2003 when multiple updates were completed, including the installation of windows (24 total), storage rooms, a toilet room, and a laundry room, along with corresponding electrical work, all totaling approximately $13,000. The building received a new roof in 2009 ($5,500) and had street space work done in 2012, along with a sewer repair that same year. Earlier improvements include the installation of aluminum windows in 1987.

The property has experienced recurring issues with parking violations in recent years, particularly involving sidewalk parking, with multiple citations issued between 2020 and 2024, suggesting an ongoing challenge with street parking management in the vicinity. The most recent violations occurred in March and December 2023, resulting in citations, while several other incidents were either addressed or resulted in the responding officer being unable to locate the offending vehicle. The property has maintained regular upkeep, with all permitted work showing as completed, though the frequency of parking-related complaints in the area could be noted as a potential concern for residents regarding access to the property.

Risk rating

How 586-588 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.
