Initial analysis

The three-story, 8-unit multi-family residential building at 783-785 Columbus Avenue in North Beach, owned by Jeffrey & Sophie Lau, has a history of maintenance and compliance issues since its 1906 construction. Most notably, the building was classified as a Tier 4 Non-Compliant soft-story structure in 2018, triggering mandatory seismic retrofitting requirements under San Francisco Building Code 505E. While recent permits from November 2023 indicate attempts to address this through commercial and residential soft-story seismic upgrades and ADA bathroom additions (totaling $95,000), a January 2023 complaint has led to active violations regarding incomplete mandatory retrofit work, with a director hearing scheduled for July 2023.

The property has experienced persistent issues with water intrusion and roof maintenance, as evidenced by multiple complaints between 2016 and 2019 regarding roof deck safety, leaks, and related problems. Building maintenance records show various attempts to address these issues through permits for roof repairs in 2016 and 2012, as well as bathroom conversions and plumbing work in 2018-2024. A cluster of building violations from 2012 (now inactive) highlighted multiple maintenance concerns requiring attention, including electrical, plumbing, interior surfaces, and security-related issues. Recent building complaints from March 2023 described the property as experiencing water intrusion, with claims of being abandoned and derelict, though these complaints were later marked as not active.

Risk rating

How 783-785 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
