Initial analysis

The property at 1630 Sanchez Street is a three-story, six-unit multi-family residential building located in Noe Valley, built in 1912 and currently owned by the Topkis Family Trust. The building has undergone several significant modifications to improve safety and maintenance, most notably completing a mandatory soft-story retrofit in 2017 at a cost of $80,000, which brought the structure into compliance with San Francisco's earthquake safety requirements. The property has experienced some maintenance issues in recent years, including a missing side sewer vent cover (resolved in January 2023) and a collapsed sidewalk (as of June 2022, this issue remains open). Historical records show a roof replacement was attempted in 1995, though that permit has since expired.

The building has been subject to routine housing inspections, with the last recorded inspection of common areas occurring in 2008. In recent years, there have been multiple reports of street-related issues near the property, including illegal parking (most recently in October 2023), overflowing city garbage cans (October 2022), and several cases requiring parking enforcement. A temporary moving truck sign request was made in March 2017 but was not fully accommodated due to space limitations. While these external issues have been documented through 311 calls, it's important to note that they primarily relate to street conditions and parking rather than the building's internal systems or management.

Risk rating

How 1630 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.

Neighborhood percentile

Out of 1879 buildings in this neighborhood, 1315 are predicted to be safer.
