Initial analysis

The 12-unit, 3-story apartment building at 650 Lake Street, built in 1963, has undergone significant maintenance and safety upgrades in recent years. The property completed a mandatory soft-story retrofit in 2016 (Tier 3) and has made substantial improvements to its life-safety systems, including a $45,208 fire alarm upgrade in 2024 that added modern notification devices throughout the building. Recent renovations include bathroom remodels in units 7 and 11 (completed in 2024), window and door replacements, stucco repairs, and a new hydronic boiler installation in 2019. The building has experienced several concerning safety issues, particularly between 2019-2020, including an elevator fire incident, multiple fire safety violations, and complaints about alarm systems and fire escapes. Though these violations were subsequently abated, they highlight the building's historical challenges with maintaining critical safety systems. Recent complaints from 2023-2024 include concerns about scaffolding work, boiler permit renewals, and elevator maintenance, with the elevator system being a recurring issue throughout the building's history. The property has undergone multiple window and door replacements over the years, most recently in 2019 when 17 aluminum windows and 16 doors were installed. Regular maintenance and improvements to the building's systems continue, as evidenced by the recent plumbing and electrical work completed in 2024, suggesting ongoing investment in the property's upkeep and modernization.

Risk rating

How 650 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, 653 are predicted to be safer.
