Initial analysis

The 550-560 Octavia Street property is a two-story, six-unit multi-family residential building located in Hayes Valley, built in 1911 and currently owned by the Nguyen Family Trust. The building has undergone several significant renovations and improvements over the past two decades, most notably completing a mandatory soft-story retrofit of its commercial portion in 2024 (previously permitted in 2017) to improve earthquake safety, and the recent installation of a beauty salon with ADA-compliant bathroom facilities in early 2024. Historical maintenance issues were addressed between 2008-2011, including fire safety concerns, water heater maintenance, and fire alarm system repairs, though these violations are no longer active.

The building's recent history shows ongoing maintenance and improvement work, with some current concerns needing attention. Most notably, there are recent complaints about graffiti (2025) and an active complaint regarding a large hole in the exterior stucco from August 2024. Multiple 311 calls in late 2024 and early 2025 have been recorded, primarily related to graffiti removal and street cleaning. The property has also undergone significant structural modifications over its lifetime, including a rear-yard variance approval for raising the building and reconfiguring lightwells, though some earlier proposed work (2005) to raise the structure by 4 feet was cancelled. Recent plumbing and electrical permits issued in February 2024 indicate ongoing improvements to the building's facilities, particularly relating to the new commercial space.

Risk rating

How 550-560 Octavia 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.
