Initial analysis

The three-unit, three-story multi-family residential building at 606-610 Lake Street, owned by Feng Sharon, was constructed in 1914 and has undergone several significant renovations and repairs over its lifetime. Most notably, in 2004, the building experienced fire damage requiring substantial structural repairs including replacement of roof rafters, ceiling joists, floor joists, and some walls, with work valued at $10,000. More recent improvements include a comprehensive electrical system upgrade in 2005 involving installation of 200-amp overhead electric service, 40 lights, 38 switches, and 110 receptacles across all three floors, as well as window flashing installation and stucco repair work in 2011. A complaint was filed in 2011 regarding work beyond the approved scope, specifically relating to dismantling the front of the building, though this issue was marked as not active in early 2012.

The building has maintained relatively good compliance with safety requirements, though there were several housing code violations noted in 2001 and 2008, including issues with fire safety systems, sanitation, security features, and gas utility requirements, all of which were subsequently abated. The most recent maintenance activity involves an open 311 call from December 2024 regarding an overgrown tree on the property. The building's infrastructure maintenance records show regular updates, including a 40-gallon water heater replacement in 2009. While there have been two fire-related incidents recorded (an invalid assist and a CO detector activation), neither resulted in civilian injuries. The property has experienced several exterior maintenance issues typical for the area, as evidenced by multiple general cleaning and tree maintenance requests through the city's 311 system, though these are primarily related to public space management rather than building-specific concerns.

Risk rating

How 606-610 Lake 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

Out of 660 buildings in this neighborhood, 409 are predicted to be safer.
