Initial analysis

The property at 3515-3517 23rd St is a two-story, multi-family residential building located in Noe Valley, owned by Pascasio Ana Reyes and dating back to 1900. The building has experienced recurring issues with water damage and maintenance needs over the years, most significantly highlighted by multiple active building violations filed in April 2024 that include concerns with water damage, mold/mildew, exterior doors, stairs, and several compliance requirements related to safety systems. These violations are currently pending resolution with a director hearing scheduled for September 5, 2024. The property has a documented history of exterior maintenance work, including recent permits from June 2024 for repairs to damaged treads and risers, as well as water-damaged exterior surfaces, indicating ongoing structural and moisture-related challenges.

The building's maintenance history demonstrates periodic attention to structural integrity and weatherproofing, with past projects including roofing work in 2007, window replacements in 2006-2007, and solar panel installation in 2010. Compliance issues appear to be a persistent concern, as evidenced by the various active violations in 2024, many of which relate to building safety and maintenance standards. Additionally, there is a pattern of parking enforcement issues documented through multiple 311 calls between 2022-2024, suggesting ongoing concerns with parking management in the vicinity of the property, though these are not directly related to the building's condition or safety.

Risk rating

How 3515-3517 23Rd 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.
