Initial analysis

The three-unit multi-family residential building at 23 Card Alley, North Beach, was built in 1907 and is currently owned by Sara R. Corbett. The property has a documented history of maintenance and compliance issues, particularly between 2004-2018, when multiple building safety violations were identified and subsequently abated, including concerns about fire safety, security requirements, smoke detection systems, and structural elements such as stairs and decks. The building received a new roof in 2001 and underwent plumbing improvements in 2017 to address code compliance issues.

More recent concerns involve several complaints about unauthorized construction work in 2016-2018, including work performed without proper permits, construction noise violations, and issues with roof access barriers. The most recent complaint from September 2022 raised safety concerns about scaffolding and work procedures between 19 and 23 Card Alley buildings, though this complaint was soon closed. The building's exterior and surrounding area have been subject to multiple 311 calls regarding garbage, debris, and hazardous materials between 2016 and 2024, though these appear to be routine urban maintenance issues rather than building-specific problems. A notable incident occurred in 2018 regarding potential short-term rental violations affecting both Unit A and B, leading to the temporary revocation of Unit A's certificate, though this was later reinstated after an appeal. The most recent building improvement was a proposed glass or acrylic transom window installation above the security gate in 2018, though the permit status remains listed as "filed."

Risk rating

How 23 Card 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.

Neighborhood percentile
