Initial analysis

The three-story, 6-unit multi-family residential building at 100-110 Shotwell Street in the Inner Mission, built in 1900, has undergone several significant improvements and faced multiple challenges over the past two decades. Most notably, the building completed a mandatory $160,000 soft-story retrofit in 2018, achieving Tier 4 compliance, though an attempted subsequent ADU conversion project in 2020 was cancelled. The property has a history of unit improvements, including bathroom and kitchen remodels in various units between 2002 and 2017, along with multiple electrical upgrades during the same periods. Several building violations were recorded in 2011-2012, including fire safety issues, maintenance concerns, and security requirements, all of which were abated by January 2013.

The property experienced multiple tenant-related issues between 2011 and 2012, including unauthorized garage conversions, plumbing work without permits, and various maintenance problems such as water leaks and fire escape concerns. More recent concerns have included complaints about a vacant unit's lights being left on (August 2020) and reports of unauthorized garage usage for woodworking purposes (June 2020). Building maintenance and safety systems have been addressed through various permits, including fireproofing repairs in 2012 and routine health and safety inspections. The building's recent history (2023-2024) shows ongoing exterior management challenges, as evidenced by multiple reports of garbage and debris on the property, though these recent complaints are primarily related to exterior maintenance rather than building systems or tenant issues. A tree maintenance issue was reported as of December 2024, and there were multiple parking enforcement calls in late 2024, indicating ongoing challenges with parking management around the property.

Risk rating

How 100-110 Shotwell 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 2380 buildings in this neighborhood, 1880 are predicted to be safer.
