Initial analysis

The two-story multi-family residential building at 11 Clarion Alley in the Inner Mission, owned by Richard Yee, contains 5 units and was constructed in 1923. The property has experienced several significant maintenance issues over the years, with the most pressing current concern being an active violation regarding lead-based paint hazards filed in September 2022, for which there is an upcoming director hearing scheduled for June 2024. The building has a documented history of plumbing and water-related problems, including a serious incident in January 2012 involving wastewater leaking onto adjacent sidewalks and multiple drainage and potable water supply issues, and exterior drainage pipe deterioration problems noted in both 2000 and 2012 complaints. These plumbing issues are corroborated by a plumbing permit for corrections issued in March 2012.

The building's safety systems have faced periodic inspections and corrections, with multiple fire alarm system activations and cooking-related incidents recorded, though none resulted in injuries or major damage. Noteworthy fire safety inspections occurred in 2017, addressing alarm systems and extinguishers, while a 2008 blocked exits issue was promptly corrected. Recent activity in early 2025 has primarily involved exterior maintenance matters, including graffiti removal and multiple reports of garbage and debris on the property grounds. The building's permit history shows minimal activity, with only a street-space permit from 2004 being of record. While the property has experienced recurring maintenance issues over the years, many historical violations have been resolved, though the current lead paint violation represents the most significant active concern at this time.

Risk rating

How 11 Clarion Aly'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.
