Initial analysis

The two-story, six-unit multi-family residential building at 447 19th Avenue in the Central Richmond neighborhood, owned by Ronald Lim and constructed in 1964, has undergone several significant safety upgrades in recent years. Most notably, in 2023, the building completed a fire alarm system upgrade costing over $17,000 to comply with city fire code requirements, with a related electrical permit issued in November 2023 for installing low-frequency sounders in sleeping areas and updating the fire panel. The building successfully completed a mandatory soft-story earthquake retrofit in 2015, meeting Tier 3 requirements at a cost of $60,000, demonstrating compliance with seismic safety standards.

The building's maintenance history indicates some past challenges with safety systems and building infrastructure, including multiple fire safety violations in 2002-2004 related to fire extinguisher maintenance, which were all resolved by 2009. A hot water supply issue was documented in 2004 and resolved by 2009. While routine housing inspections have generally shown compliance, there have been several reports of garbage and debris issues in recent years (2024-2025), though these were related to street cleaning concerns outside the building rather than interior maintenance issues. The most recent building improvements focus on life safety systems, particularly fire alarm infrastructure, with no active violations or complaints currently on record, suggesting improved overall maintenance and safety compliance in recent years.

Risk rating

How 447 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
43th percentile

Out of 2250 buildings in this neighborhood, 1282 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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

Building age

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

12-Month severity forecast
No violation 75.3%
Moderate concern 15.8%
Severe concern 8.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
