Initial analysis

The six-unit, three-story multi-family residential building at 1100 Lombard Street in Russian Hill, constructed in 1900, has undergone several significant safety and modernization upgrades over the years. The building was extensively renovated between 2012-2014, with major improvements including the installation of a comprehensive fire safety system (fire alarm, sprinklers, and standpipe system), electrical system upgrade (400-amp service, rewiring), and the construction of new rear egress stairs and roof decks. Multiple fire safety violations were recorded between 2010-2023, including issues with extinguishers, sprinkler systems, and alarm systems, though these violations were generally corrected promptly. Most recently, there was a sleeping area requirement violation issued in December 2023 that remains open.

The property has maintained active exterior maintenance through regular permits for street space usage, with the most recent permit issued in 2018. The building's plumbing system has seen significant upgrades, including new gas lines, waste systems, and multiple bathroom renovations, with the most recent work completed in 2018. While there have been several 311 calls regarding the property in 2024, most relate to exterior issues such as garbage, graffiti, and street maintenance rather than building-specific concerns. The building's recent history suggests ongoing attention to safety systems, though some open violations remain, particularly regarding the sleeping area requirements. The property has experienced multiple false fire alarms and system malfunctions over the years, with no reported civilian injuries from any fire-related incidents.

Risk rating

How 1100 Lombard 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 1133 buildings in this neighborhood, 725 are predicted to be safer.
