Initial analysis

The 80-unit Warrington Apartments, located at 775 Post Street in Downtown San Francisco, is a 6-story multi-family residential building constructed in 1913. The property has undergone extensive recent renovations, with multiple apartment upgrades between 2021-2023 including kitchen remodels, electrical rewiring, and plumbing improvements in units 102, 511, 301, 104, 505, and 604. Significant infrastructure updates include a new fire alarm system installation in 2019 replacing the old system to comply with 2016 codes, and the replacement of both the steam boiler and water heater in 2021. However, the building has faced several concerning issues, particularly in 2021-2022, including three separate elevator rescues, multiple fire code violations, and documented rodent infestations affecting multiple floors. The fire safety system has shown persistent violations, with multiple fire code violations cited between 2021-2024, including issues with alarms, extinguishers, and sprinkler systems. Infrastructure maintenance has been ongoing, as evidenced by various plumbing and electrical upgrades, though there have been recent complaints about building maintenance including broken windows and potential leaks. A notable historical incident occurred in 2013 regarding unauthorized cell site facility installation, though this was abated by 2015. Recent 311 calls from 2024-2025 indicate some ongoing maintenance challenges, particularly related to sidewalk cleanliness and waste management around the property.

Risk rating

How 775 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.
