Initial analysis

The 16-unit apartment building at 1141 Post Street, owned by 1141 Post Holdings LLC and constructed in 1915, has experienced several significant maintenance and safety issues in recent years. Most notably, there have been persistent problems with the roof, including leaks reported in both 2021 and 2022 that raised concerns about electrical safety, though a roof repair was completed in 1990 and further work was undertaken in 2022 with a $30,000 kitchen remodel in Apartment #5. The building has faced multiple fire safety compliance issues, with the most recent violation related to sleeping area requirements issued in December 2023, while earlier violations involved problems with fire escape ladders (2003), fire extinguishers (2022), and sprinkler systems (2017). In 2021-2022, unauthorized modifications to the building were discovered, including the installation of a laundry room with new electrical and plumbing systems, for which the owner eventually obtained permits in 2022. The property has also experienced periodic sanitation issues, including rodent infestation (2022) and deteriorated water lines (2022), though these violations were marked as abated by April 2023.

Recent inspection history reveals ongoing concerns about building maintenance and safety systems, with multiple fire safety inspections showing various violations between 2009 and 2023. The most pressing current violation relates to sleeping area requirements as of December 2023. The building's management has shown some responsiveness to maintenance issues, as evidenced by recent permitted work in Apartment #5 and the legalization of the laundry room, though these followed periods of complaint investigation and violation notices. The property has maintained regular housing inspections over the years, with the most recent routine inspections occurring in 2022 showing various building system issues. While many complaints have been resolved, recent 311 calls from late 2024 indicate ongoing external maintenance challenges, particularly regarding garbage and debris management in the vicinity of the building.

Risk rating

How 1141 Post 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 85 buildings in this neighborhood, 46 are predicted to be safer.
