Initial analysis

The property at 1849-1851 9th Avenue in San Francisco's Inner Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1965 and currently owned by the Vivian M Lui Survivors Trust. The building's maintenance history shows regular upkeep of its essential systems, including a complete reroofing project in 2003 costing $6,740 and an electrical upgrade in September 2003 involving an underground service conversion with two meters and 150-amp service, both of which were successfully completed. In 2004-2005, exterior improvements were made including the installation of fiber cement siding on an exterior wall and repair and painting of the back stairs, which were documented as completed projects.

The property has experienced several parking-related issues in its vicinity over recent years, with four documented incidents between 2018 and 2024, including cases of driveway blocking and sidewalk parking. Most recently, in January 2024, there was an attempted enforcement response to a blocked driveway case involving a Tesla, though the officer was unable to locate the vehicle. These parking-related incidents, while relevant to the building's surroundings, are external to the property itself and appear to be recurring neighborhood issues rather than specific building concerns. The most recent building permit activity on record dates back to 2005, suggesting that no major building modifications or repairs have been undertaken in nearly two decades, though this absence of recent permits is not necessarily indicative of any current issues with the property.

Risk rating

How 1849-1851 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.
