Initial analysis

The two-unit residential building at 525-527 Lombard Street in North Beach, owned by Chan & Zygaj Revoc Trust, is a two-story structure built in 1925, classified as Flats & Duplex. The property has undergone several significant improvements over the years, with the most substantial being a complete re-roofing project completed in 2019 costing $24,000. In 2008, the building underwent notable plumbing work including the installation of a half bath, replacement of a sewer trap (which had been the subject of a complaint when it rendered the toilet unusable for one day), and replacement of a clay pipe section with new cast iron piping. The same year also saw an electrical upgrade during the lower basement remodel involving the installation of lighting and receptacles.

The building's maintenance record shows regular upkeep, with multiple street space permits issued in 2008-2009, indicating ongoing attention to public space requirements. While the property has experienced two fire-related incidents recorded in the system, these were not emergencies (a false alarm and a gas leak that required no civilian evacuation or injuries). The surrounding area has seen several reports of abandoned vehicles between 2015-2017, though these were all resolved when the vehicles were no longer present. A damaged tree was reported and addressed in 2008. The building's maintenance history suggests regular upkeep, with no recurring issues or serious safety concerns noted in recent years.

Risk rating

How 525-527 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
