Initial analysis

The 14-unit, 3-story apartment building at 501 28th Avenue in the Central Richmond neighborhood, owned by Yukiko Yoshimura Exempt Trust, was constructed in 1962 and has undergone several significant safety upgrades in recent years. Most notably, in 2024, the building received major fire safety improvements, including a new code-compliant fire system with upgraded panels, smoke detectors, and communication equipment, with work continuing into 2025 for final system adjustments. The building has completed mandatory seismic retrofitting as a Tier 3 soft-story property, including installation of new plywood shearwalls and steel frames in 2015, demonstrating compliance with San Francisco's seismic safety requirements.

The building's maintenance record shows attention to fundamental systems, including a house trap replacement in 2014 and historical window and roofing work in the late 1990s and 1989, though some older permits have expired. While there have been several fire safety violations noted between 2000 and 2024, they were generally addressed promptly, with no civilian injuries recorded in any fire incidents. Recent activity includes multiple reports of garbage overflow issues (January 2025) and routine maintenance of alarm systems, though an August 2024 violation regarding alarm system maintenance (since abated) indicates some ongoing challenges with building systems. The property has maintained active response to housing inspections, with all known violations being resolved, and completed routine plumbing and electrical work as needed, including wireless low-frequency horn installations as part of fire safety upgrades in 2024.

Risk rating

How 501 28Th 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.

Neighborhood percentile

Out of 2250 buildings in this neighborhood, 2205 are predicted to be safer.
