Initial analysis

The property at 517 11th Avenue in San Francisco's Inner Richmond district is a two-unit, two-story multi-family residential building constructed in 1913. The most significant recent renovation occurred in 2007-2008, when a substantial $325,000 project was completed that included both horizontal and vertical additions at the rear yard, interior remodels of both units to enhance bedroom and bathroom sizes, and new rear stairs. This renovation was followed by comprehensive updates in 2011, including complete rewiring of both units with a 200-amp service upgrade, installation of new bathrooms, kitchen fixtures, plumbing systems, and a new furnace. The building had some maintenance issues in its earlier history, including a 1998 complaint about wood rot and questionable bathroom additions, and permits from 1991 and 1995 for facade and roofing work that are now expired.

Recent activity around the property includes several 311 calls between 2016 and 2024, primarily relating to street and sidewalk maintenance issues such as garbage, debris, and water-related concerns. Most notably, there were multiple water leak reports between 2016 and 2017, though investigations found no actual leaks, only ground water. The building's most recent exterior issues include a pavement defect reported in September 2023 that remains open as of now. The most recent incidents demonstrate typical urban neighborhood challenges, including recent cases of abandoned furniture, blocked driveways, and temporary encampments, though these relate more to the immediate street environment than the building itself.

Risk rating

How 517 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.

Neighborhood percentile

Out of 1723 buildings in this neighborhood, 879 are predicted to be safer.
