Initial analysis

The property at 1078-1080 Clay Street in San Francisco's Nob Hill neighborhood is a two-unit, two-story multi-family residential building constructed in 1933, currently owned by Bradford A. Butterworth. The building has a documented history of structural issues, most notably a serious foundation problem that came to light in late 2018 when violations were filed regarding a vertical crack in the concrete foundation wall and exposed/undermined bottom foundation, which posed potential hazards to occupants and neighboring properties. This critical issue required foundation repair and partial replacement work valued at $24,000, which was completed in June 2019. Earlier maintenance records from 1997 indicate the building underwent reroofing work and repairs for beetle damage and fungus-related floor issues, though these permits have since expired.

More recent history of the property reveals primarily routine maintenance and administrative matters, with several 311 calls recorded between 2012 and 2024. These calls have generally concerned external factors such as street cleaning, garbage issues, missing infrastructure (like a side sewer vent cover), and occasional neighborhood maintenance concerns, including reports of encampments in the vicinity, though these were investigated and found to have no impact on the property. The most recent reported issue was a garbage and debris complaint from December 2024, which was successfully resolved. The building's current condition appears stable since the resolution of the significant foundation issues in 2019, with no recent major structural concerns reported through official channels.

Risk rating

How 1078-1080 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.

Neighborhood percentile
