Initial analysis

The two-story, six-unit multi-family residential building at 146 3rd Avenue in the Lake-Presidio neighborhood, owned by Kathy N Y Liu, has undergone several significant safety and maintenance improvements since its construction in 1964. Most recently, in August 2023, the building received a comprehensive upgrade to its fire alarm system, including the installation of low-frequency sounders, which was completed with an electrical permit in March 2024. This $22,808 project brought the non-sprinkler building into compliance with current fire code requirements. In 2020, the property underwent structural maintenance with the replacement of a concrete retaining wall and fence in the backyard, which had suffered from cracking and tilting, at a cost of $20,000.

The building's maintenance history shows attention to fire safety concerns, with multiple violations addressed in 2002 and 2015 inspections, including issues related to fire extinguisher servicing, door security, and egress obstructions, all of which were promptly corrected. Recent activity at the property has primarily consisted of parking-related issues, with multiple citations issued between 2022 and 2023 for vehicles blocking driveways, though these are not directly related to building conditions. Historical complaint data from 2014 regarding trash receptacle management was also resolved, indicating general responsiveness to property maintenance standards. The building's records suggest active management response to regulatory requirements, particularly regarding fire safety systems, with all identified violations being addressed and corrected in a timely manner.

Risk rating

How 146 3Rd 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
69th percentile

Out of 660 buildings in this neighborhood, 205 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 78.5%
Moderate concern 12.8%
Severe concern 8.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
