Initial analysis

The property at 1322-1324 40th Avenue in the Outer Sunset is a two-story, three-unit multi-family residential building constructed in 1946 and owned by Yeung Pae Fun. The building has experienced recurring maintenance issues over recent years, particularly with plumbing and electrical systems. Most notably, there have been multiple complaints about water-related problems, including reports in 2024 of a bathroom faucet issue and sink leak, and a 2023 complaint about no water in the kitchen faucet. Previous violations from 2018-2020 indicated problems with shower/tub repairs, window and toilet issues, and various electrical concerns such as light switches and fire safety compliance. The building underwent several significant improvement projects, including a kitchen and bathroom remodel in 2011 ($18,000), a 200-amp electrical service upgrade in 2003, and various plumbing and electrical improvements.

The property has an active complaint from 2019 regarding possible illegal units behind the garage, and there have been multiple parking-related enforcement actions in recent years, particularly regarding driveway blocking and sidewalk parking violations. The building's maintenance history shows periodic attention to updating and repairing basic systems, with recent work including window replacement in 2023 and bedroom heater installation in 2023. While some historical maintenance issues have been addressed, the frequency of recent plumbing and electrical complaints suggests ongoing challenges with building systems. The property has maintained basic compliance with housing standards, though several complaints and violations indicate periods of deferred maintenance requiring tenant intervention for resolution.

Risk rating

How 1322-1324 40Th 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.
