Initial analysis

2533 Lake Street is a two-story, five-unit multi-family residential building constructed in 1923, currently owned by Fong Gst Non Exempt Marital. The building's maintenance history shows several significant repairs and inspections, with the most serious issues occurring in 2001 and 2008. During a routine inspection in 2001, multiple safety concerns were identified including repairs needed for stairs, a problematic central alarm system, combustible storage issues, lead paint hazards, emergency egress obstruction, and smoke detection failures; all of which were abated by August 2001. A similar pattern of violations occurred during an inspection in 2008, where the building was cited for security door issues, gas utility safety requirements, and alarm system certification needs, though these were resolved by September 2008. The property has undergone several physical maintenance tasks over the years, including reroofing work in 1997 and repair to dry rot in 2005, particularly affecting the back stairs and rear of the house.

Recent activity at the property includes several 311 calls from 2018 to 2023, though most relate to external issues such as illegal postings, parking violations, and street cleaning matters rather than building-specific concerns. The most recent building-relevant interaction was a hazardous materials report in December 2023, which was resolved with before-and-after photos taken and uploaded to the records. A construction noise complaint was filed in June 2022, suggesting some ongoing maintenance or improvement work at the property, and there was a sewer issue reported in March 2009 involving water discharge. While the building experienced significant safety violations in the early 2000s, records indicate these were addressed at the time, though the relative age of the building (100 years old) suggests ongoing maintenance needs are to be expected.

Risk rating

How 2533 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
22th percentile

Out of 660 buildings in this neighborhood, 515 are predicted to be safer.
