Initial analysis

The 871-873 Capp Street property is a 2-story, 8-unit multi-family residential building constructed in 1900, currently owned by Boon Capp Holdings LLC. The building has undergone significant work in recent years, including the installation of a comprehensive fire sprinkler system throughout both front and rear buildings in 2021, and the addition of four ADUs (Accessory Dwelling Units) to accommodate a total of 12 residential units on the lot. In July 2022, the property experienced a fire incident that damaged the front stairway, though permits were subsequently issued for its replacement. However, more concerning issues have recently emerged, with multiple complaints in 2024 reporting the building as "abandoned/derelict," citing problems with rodents, structural decay, and hazardous conditions. These complaints describe the property as having overgrown areas, exposed wiring, and insufficient maintenance following the 2022 fire.

The building's recent history shows a pattern of delayed construction progress and safety concerns, with multiple permits being renewed or recommenced in 2024, including plumbing and electrical work. Historical records indicate various building violations from 2002 through 2016, including issues with fire escape ladders, window repairs, fire safety equipment, and security requirements, though these violations were eventually abated. The property has also experienced recurring issues with graffiti (most recently in 2023), and there have been several 311 calls regarding the building, including noise complaints and sidewalk parking violations. While some improvements have been made over the years, including electrical system upgrades and plumbing renovations, the recent complaints about abandonment and pest problems suggest ongoing maintenance challenges.

Risk rating

How 871-873 Capp 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
