Initial analysis

The 4-unit, 2-story multi-family residential building at 9-11 Lexington Street, located in the Inner Mission neighborhood, has undergone several notable maintenance and improvement projects since its construction in 1910. Most recently, a reroofing project valued at $12,500 was permitted in October 2024, involving the installation of a new three-layer built-up roof system. The building's maintenance history includes various significant repairs and upgrades, such as kitchen renovations in Unit 1 (2014), siding replacement on a blind wall (2008), and the repair of dry rot on the deck and front door in 1999. The property has undergone routine housing inspections in 1999 and 2008, both of which were resolved without any active concerns.

In terms of recent cleanliness and maintenance issues, there have been multiple reports of garbage and debris on or near the property throughout 2023 and 2024, with six documented cases between May and October 2024, all of which were resolved. These incidents indicate an ongoing challenge with waste management in the vicinity. Additionally, there was one report of graffiti in June 2023 and an illegal parking complaint in September 2023, both of which were addressed by appropriate authorities. The building's ownership is registered to Kien Va Nguyen and Bien Thi Tra, and while the property has maintained compliance with housing inspections, the frequency of recent cleaning-related complaints suggests some challenges with ongoing property maintenance.

Risk rating

How 9-11 Lexington St'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.
