Initial analysis

1840 Green Street is a 6-unit, 3-story multi-family residential building constructed in 1915, currently owned by the Louis F Legnitto Revocable Trust. The building has undergone several significant safety and infrastructure improvements over the past two decades, with the most recent notable work being a completed soft-story retrofit in 2015 (classified as Tier 3) which received its Certificate of Final Completion (CFC). Between 2008-2012, substantial structural improvements were made including the installation of a new furnace system with proper ventilation in 2008, structural strengthening work with steel framing and plywood panels in 2012 ($50,000 project), and seismic safety improvements including the installation of an earthquake shut-off gas valve in 2010.

The building experienced several safety-related violations in 2003-2008, primarily related to fire safety concerns such as egress obstructions, fire escape maintenance, and gas meter regulations, all of which were successfully abated by December 2008. In recent years, there was a construction-related complaint in 2020 regarding social distancing violations, and routine safety inspections have been conducted, including a 2016 inspection. The property has maintained its basic infrastructure, as evidenced by recent plumbing and repair permits, and has addressed environmental health matters as shown by recent cleaning permits. External to the building, there have been occasional issues with street parking and sidewalk use, as evidenced by multiple 311 calls about parking violations and street cleaning matters, though these are not directly related to the building's condition or management.

Risk rating

How 1840 Green 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
