Initial analysis

The property at 688-690 Sacramento Street is a two-story, multi-family residential building with commercial space, constructed in 1916 and currently owned by Jo Tim & Anette Siu Revocable Trust. The building has undergone numerous modifications and improvements over the years, with the most recent permit (issued May 2024) focusing on bathroom door modifications. A significant commercial renovation occurred in 2016, including kitchen equipment relocation, accessibility improvements, and the installation of new plumbing and electrical systems, totaling over $7,200 in costs. The building's seismic retrofitting was completed in 1997, and various other renovations have been documented between 1990 and 2008, suggesting regular maintenance and upgrading of both residential and commercial components.

Of particular concern are the multiple fire code violations recorded between 2019 and 2024, with the most recent violations issued in December 2024. These violations, which require immediate attention according to fire safety standards, include issues with the fire alarm system, emergency lighting, and other safety features. The building has experienced several false alarms and system malfunctions related to its fire detection equipment, though no actual fires have been recorded. A building complaint was filed in June 2024 regarding unauthorized demolition work and noise disruptions, though this was abated within two days. Recent 311 calls from late 2024 show typical urban issues including graffiti, debris, and transportation-related concerns, though these are not directly related to building conditions. The property has also secured several liquor license approvals, most recently in 2023, indicating active commercial operations in the ground-floor retail space.

Risk rating

How 688-690 Sacramento 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.
