Initial analysis

The 5-unit, 2-story multi-family residential building at 519 24th Ave in Central Richmond, built in 1923, has undergone several significant safety and infrastructure improvements in recent years. Most notably, the building completed a mandatory soft-story retrofit in 2016 at a cost of $150,000, demonstrating seismic safety compliance as a Tier 3 building. The property has recently received important fire safety upgrades, including a comprehensive fire alarm system modernization completed in April 2024, which involved upgrading the fire panel, updating existing devices, and installing low-frequency sounders in sleeping areas to meet current code requirements. Other major improvements include the replacement of windows in 2016-2017 (updating from 8 to 12 windows), water system upgrades including a pressure regulator installation, and HVAC improvements such as replacement of wall heaters and flue systems in 2014.

The building's maintenance history shows regular attention to infrastructure needs, with multiple street space permits issued, though these generally relate to temporary street use rather than building conditions. Two routine housing inspections in 2002 and 2011 resulted in no ongoing issues. More recently, there have been several public works incidents documented through 311 calls between October 2024 and December 2024, primarily relating to graffiti and street cleaning matters, though these external issues appear to have been resolved through normal municipal processes. The building's on-record permits suggest active management of safety and maintenance concerns, with all major infrastructure work being properly permitted and completed.

Risk rating

How 519 24Th 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.
