Initial analysis

The three-story multi-family residential building at 78-80 Sanchez St in Duboce Triangle, owned by Eleanor Lorraine Thompson R, contains 17 units and was constructed in 1904. The building has undergone several significant improvements over the past decades, with the most recent major work being a completed ground-level seismic retrofit in 2016 (costing $100,000) under the wood frame seismic retrofit program. This building is classified as Tier 3 in the soft-story program, and has achieved work completion and received its Certificate of Final Completion (CFC). Historical records reveal some notable events, including the repair of smoke damage from a fire in 1996, foundation leak issues in 1998, and various improvements in the 1990s such as chimney replacement following an earthquake and exterior siding repairs.

Recent maintenance and safety compliance issues have been documented, with multiple violations noted in 2023, including problems with fire extinguisher maintenance, gas utility shutoff tool access, and fire escape ladder condition. These violations were filed under the 2023 complaint number 202303286 and were subsequently abated by April 2023. Additionally, the building underwent three complaints/inspections in 2016, including a lead paint hazard investigation and an interior remodel issue in the garage. Historical complaints from the early 2000s identified various building safety concerns that were resolved, such as guardrail stability, security requirements, and the need for appropriate viewer installations on unit doors. The property has maintained active compliance with most building codes, as evidenced by the prompt addressing of violations, with the notable exception of a 2009 kitchen remodeling permit for unit #2 being issued but not marked as complete in the records. Recent external maintenance issues were addressed through 311 calls in 2019-2020 for general cleaning and graffiti removal.

Risk rating

How 78-80 Sanchez 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.
