AI summary

The 6-unit multi-family residential building at 581-591 Francisco Street in North Beach, constructed in 1912 and currently owned by Chang Weng Si, has undergone several significant improvements and faced notable challenges over its recent history. Most concerning is a 2020 complaint regarding the building's status as a potential unregistered soft-story structure, which could pose seismic safety concerns. The building has experienced multiple renovation projects, including a 2018 attempt to legalize roof decks, 2014 kitchen remodels, and mechanical upgrades including new heating units and fire alarm systems. Notable compliance issues were recorded in 2011-2012 regarding improperly rebuilt exterior stairs and various building maintenance violations that were subsequently abated. The building has a history of construction-related complaints, particularly in 2009-2013, including issues with egress obstruction, exposed wiring, and exterior work being performed without proper permits. Recent activity (2024) has primarily consisted of maintenance-related 311 calls, mostly regarding street-level issues such as parking violations and debris removal.

The structure has experienced several fire-related incidents, though none resulted in injuries - these include multiple cooking-related incidents and detector activations. A comprehensive fire safety upgrade was completed in 2012 with the installation of a new fire sprinkler system throughout the building. The building underwent significant electrical and plumbing improvements between 2011-2015, including new electrical systems installation in 2011-2012 and multiple plumbing repairs. Annual inspections in 2013 and earlier routine housing inspections have been completed, though specific findings from these inspections are not detailed in the available records.

Risk rating

How 581-591 Francisco 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.
