Initial analysis

The three-unit residential building at 1040-1044 Clay Street in San Francisco's Nob Hill neighborhood is a three-story structure built in 1906, currently owned by Chang Properties. The property has undergone several significant renovations over its history, with the most substantial work occurring in 2011, when Unit #1042 received a $35,000 kitchen and bathroom remodel, including new furnace ductwork and flue installation, though one plumbing work permit from April 2011 expired without completion. Prior to this, the building underwent various improvements in 1998-1999, including cabinet and appliance replacements.

The building has a history of maintenance and safety compliance issues, with a recent violation filed in March 2024 regarding smoke/carbon monoxide detector compliance and several other general maintenance concerns. Previous violations include a 2000 incident related to fire extinguisher maintenance and security requirements, which were promptly addressed within the same month. The property has been subject to routine housing inspections, including a 2016 inspection that identified stairs and structural maintenance issues, all of which were resolved. Recent activity around the building (2023-2025) has mostly involved street-level concerns such as garbage and debris reports, with multiple cases being resolved through city services. While the building has experienced periodic maintenance issues, records show that violations are generally addressed in a timely manner. The most recent significant building-related violation (March 2024) has not yet been documented as resolved in the available records.

Risk rating

How 1040-1044 Clay 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.
