Initial analysis

The three-story multi-family residential building at 4 San Antonio Place, located in Telegraph Hill, was built in 1907 and contains 4 units. The property has undergone several significant modifications and faced various regulatory challenges in recent years. Most notably, in 2023, a permit was filed to address compliance with a city planning enforcement notice regarding unit mergers. The building has received substantial safety upgrades, including the installation of a fire sprinkler system (2015), backflow prevention (2021), and elevator electrical work (2015). Historical issues included multiple lead paint violations in 2010, which were resolved by 2011.

Recent complaints and modifications suggest ongoing management attention to the building's needs. There have been several complaints about building conditions, including inadequate exterior maintenance in 2010 and work beyond the scope of approved permits in 2022. A significant planning application is currently under review to address unauthorized unit mergers and modifications, with the owner seeking to reinstate 3 dwelling units while complying with current regulations. The property has experienced multiple fire safety system activations, though all were determined to be non-hazardous, including false alarms and detector malfunctions.

Risk rating

How 4 San Antonio Pl'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.
