Initial analysis

The property at 776-782 Columbus Avenue in San Francisco's North Beach neighborhood is a 2-story, 5-unit multi-family residential building constructed in 1907, currently owned by Tranquilo LLC. The building has undergone several significant infrastructure upgrades in recent years, including the replacement of the house trap in 2016, installation of a new water main and plumbing systems in 2014, and the removal of AT&T cell equipment in 2015. Historical records show multiple roofing projects dating back to 1992, and important safety improvements such as the installation of fire sprinklers and extinguishers in 1988.

The building experienced a series of compliance issues in late 2007 related to fire safety, building access, and unauthorized dwelling units, which were documented through multiple violations and inspections but were all abated by February 2008. A complaint about illegal basement rental was filed in 2009 but was resolved within two weeks. Subsequent routine inspections in 2005 and 2002 identified various maintenance needs, including lighting improvements and general repairs, all of which were addressed. The most recent documented fire safety incident involved smoke or odor removal with no civilian injuries recorded. While there have been multiple 311 calls recorded in the vicinity of the building between 2024-2025, these primarily relate to park services and maintenance issues rather than building-specific concerns. The property appears to have maintained compliance with building codes since the resolution of the 2007 violations, with no active violations or major safety concerns on record.

Risk rating

How 776-782 Columbus Ave'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
