Initial analysis

This two-unit, two-story multi-family residential building, located at 343-345 11th Avenue in San Francisco's Inner Richmond neighborhood, was built in 1922 and is currently owned by the May Wah Wong Bypass Trust. The property has undergone several significant improvements over the years, with the most substantial renovation occurring in 2006-2007, when major structural modifications were completed including the removal of a bearing wall and installation of steel beams, along with electrical upgrades featuring extensive lighting and receptacle installations. The building has received regular maintenance attention, with a roof replacement performed in 2008 costing $5,500, and has required multiple street space permits, the most recent of which was issued in 2017.

The property has experienced several maintenance and service issues in recent years, including a sewage backup in March 2022 that required intervention from PUC Sewer Operations and some recurring problems with parking enforcement, particularly related to a Toyota RAV4 that was cited for blocking the driveway in both April and November 2022. Other notable incidents include reports of garbage and debris issues in 2024 and 2022, though these were resolved by city services. The building's permit history shows a consistent pattern of proper maintenance and upgrading of facilities, with no recorded major safety violations or complaints. Street-related issues have been addressed through appropriate city departments, including Recology for waste-related matters and DPW for graffiti and general cleaning concerns.

Risk rating

How 343-345 11Th 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.
