Initial analysis

The two-unit residential building at 24-26 Bonita Street in Russian Hill, owned by Detjen H Louis Jr, is a two-story flats and duplex structure built in 1907. The building's maintenance history shows several important infrastructure upgrades, including a complete reroofing project completed in 2008 costing $9,000, a rear stairs repair project in 2011 involving picket installation and concrete steps, and an electrical service upgrade in 2006 that followed an earlier expired permit application from 2005, indicating attention to both structural and systems maintenance over the years.

Recent activity around the property between 2022 and 2025 has been characterized by a number of external environmental and public space issues, rather than problems directly related to the building's condition or systems. These include multiple incidents of garbage and debris on public sidewalks, two instances of human or animal waste (in August 2022 and September 2023), and various parking enforcement matters including vehicles blocking driveways and parking on sidewalks. The most recent incident was in January 2025, involving a defaced MTA sign, though this is unrelated to the building itself. Of particular note was a November 2024 incident involving a refrigerator appliance and a homeless individual in a sleeping bag, though the report indicates some connection to the building's property and multiple agencies were involved in the resolution. While these external issues don't necessarily reflect on the building's condition, they may impact the immediate neighborhood environment.

Risk rating

How 24-26 Bonita 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.

Neighborhood percentile

Out of 1133 buildings in this neighborhood, 329 are predicted to be safer.
