Initial analysis

The 5-unit, 3-story multi-family residential building at 257-263 Pierce Street in Hayes Valley, owned by Giampaolo Boschetti, was constructed in 1895 and has undergone several significant structural and safety improvements over its lifetime. Most notably, the building completed a mandatory soft-story retrofit in 2017 as a Tier 3 building, achieving final approval with Certificate of Final Completion (CFC) status. The property faced considerable challenges in 2013-2014, including serious concerns regarding plumbing and electrical systems, as evidenced by multiple complaints about water leaks, toilet issues, and heating system problems, along with safety concerns about a water heater and electrical outlets that sparked. These issues were addressed through various permits and repairs, including structural revisions and utility upgrades in 2018.

The building's maintenance history shows attention to safety and habitability concerns, with several major improvements completed over the years. In 2018, comprehensive electrical and plumbing work was performed, including kitchen and bathroom remodels, rewiring, and replacement of heating systems. The building has completed numerous other maintenance tasks, including deck repairs, stair repairs, and roof work, though some historical violations from 2001 (regarding heat, stairs, windows, and deck conditions) and 2013 (plumbing and electrical issues) were all marked as not active and appear to have been resolved. Recent activity at the property has been minimal in terms of building permits, with only routine maintenance and street space permits issued in 2019. The fire safety systems were verified as functioning in 2013, and there were no recorded fire incidents or injuries. While there have been multiple 311 calls regarding the property in recent years (2024), these primarily relate to external building maintenance issues such as graffiti and debris, rather than internal habitability concerns.

Risk rating

How 257-263 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.
