Initial analysis

The 6-unit, 2-story multi-family residential building at 463 19th Avenue in the Central Richmond neighborhood, owned by Quan Joanne Moon, has undergone several significant safety and maintenance improvements in recent years. Most notably, in 2022, the building received substantial fire safety upgrades including the installation of a new fire alarm system with low-frequency sounders to comply with San Francisco Fire Department requirements, followed by corrections to fire panel and detector specifications. In 2022, units 3 and 6 had their windows replaced with modern vinyl frame windows, and the building's roof was previously replaced in 1997. Historical records from the early 2000s show multiple safety violations that were subsequently addressed, including concerns about egress obstructions, lead paint hazards, and various fire safety issues, all of which were abated by December 2002.

The building has maintained an active safety compliance record, with periodic inspections and prompt responses to fire-related concerns. A combustible materials issue was identified and corrected in 2018, and multiple fire alarm system inspections were conducted in 2005 and 2009. Recent history shows no active building violations or major safety concerns, though there have been recurring issues with sidewalk parking in the vicinity as documented through 311 calls between 2020 and 2024. The most recent building-related incidents were routine park patrols in 2023, which involved enforcement of park rules rather than building-specific issues.

Risk rating

How 463 19Th 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
23th percentile

Out of 2250 buildings in this neighborhood, 1732 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Property class: mixed-use w/ SFR

Mixed-use property including a single-family residential component.

12-Month severity forecast
No violation 73.8%
Moderate concern 19.5%
Severe concern 6.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
