Initial analysis

The building at 147-149 9th Avenue is a two-unit multi-family residential structure built in 1921, currently owned by Diane C. Yee. The property has undergone minimal permitted improvements over the decades, including aluminum window installation in 1987 and reroofing in 1997, though the latter permit has since expired. A significant recent complaint was filed in September 2023 regarding inadequate water access during an event, specifically the absence of water fountains or bottle filling stations, with the issue marked as active in the Building Inspection Division. The building experienced a construction-related disturbance in May 2020, though this complaint is no longer active.

The property has a notable history of sewer-related issues, with three separate incidents documented between 2015-2016 involving sewage backup problems and grease buildup in the system, indicating potential infrastructure challenges. Parking has been a recurring issue in the vicinity, with multiple complaints about vehicles blocking driveways between 2015 and 2024, suggesting ongoing enforcement challenges in the area. The surrounding environment has experienced some maintenance issues, including a damaged tree incident (2019) that was scheduled for removal during regular maintenance, and a general garbage cleanup request in 2019 that was resolved. While these historical issues paint a picture of a property with some maintenance and infrastructure concerns, it's worth noting that the most recent permit activity and significant complaints have been relatively limited.

Risk rating

How 147-149 9Th 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.
