Initial analysis

The 5-unit, 3-story multi-family residential building at 401-409 Capp Street, owned by the Man & Jeng Family Trust, was constructed in 1900 and has undergone several significant improvements and faced various maintenance challenges over the years. Most notably, the building completed a mandatory soft-story seismic retrofit in 2018 at a cost of $73,950, bringing it into compliance with San Francisco's seismic safety requirements. Recent complaints from 2024 have raised concerns about a beeping fire alarm in unit 403, which has reportedly been ongoing since January 2024, suggesting a maintenance issue with fire safety systems. The property has experienced recurring issues with windows, as evidenced by multiple complaints in 2022 regarding broken and improperly operating windows.

The building's history includes several important maintenance and compliance actions, such as the removal of two advertising signs in 2012, repair of stairs due to dry rot in 2002, and various electrical and plumbing improvements. A significant cluster of building violations was documented in 2001-2002, including issues with fire escape ladders, door security features, and stair repairs, though these were all subsequently resolved. In 2022, multiple violations were recorded including problems with smoke detectors, lighting, rodent infestation, and general maintenance concerns, all of which were addressed by April 2022. The property has also faced external challenges with graffiti and street cleaning issues, as evidenced by multiple 311 calls in recent months regarding garbage overflow and graffiti on or near the property. While historical complaints suggest periodic maintenance issues, many have been addressed through proper channels and permits, indicating generally responsive property management, though the persistence of recent fire safety concerns warrants attention.

Risk rating

How 401-409 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

5th percentile

Out of 2380 buildings in this neighborhood, 2261 are predicted to be safer.
