Initial analysis

The three-story multi-family residential building at 316-320 Pierce Street in Hayes Valley, owned by Dinah F Blanson 2014 Revoc, was constructed in 1911 and contains three units. The most recent significant work on the property was completed in April 2024, involving a $19,500 reroofing project. The building has experienced several maintenance issues over its history, including multiple violations in 2008 related to stair repairs, lead paint concerns, and fire safety equipment requirements, all of which were abated by August 2008. A 2009 complaint reported heating problems and electrical issues, which were resolved within weeks.

The property has undergone various infrastructure maintenance projects, including sidewalk repairs in 2002 and a furnace replacement in 2009. More recently, there have been recurring issues with missing side sewer vent covers, with reports filed in October 2023 and April 2024. The building's fire safety system has experienced several false alarms and system activations, including smoke detector and carbon monoxide detector activations, though none resulted in any injuries. While the building has had its share of maintenance challenges, most violations and complaints have been addressed promptly, with no active violations currently on record. Recent 311 calls from 2024-2025 primarily relate to street cleaning and parking enforcement issues near the property.

Risk rating

How 316-320 Pierce 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.
