Initial analysis

The property at 55-57 Salmon Street in Nob Hill is a 1907 two-unit multi-family residential building currently owned by the Leo J & Anna Wong Revocable Trust. The building has undergone several significant renovations and improvements over the past two decades, with the most substantial work occurring in 2018-2019 when both units received extensive updates including kitchen and bathroom remodels, electrical upgrades, and HVAC improvements. This phase of renovation, costing approximately $100,000, included filling in an interior lightwell, reconfiguring rear stairs, and general upgrades to mechanical, electrical, and plumbing systems. A building complaint was filed in late 2019 regarding potential work beyond the scope of the permit, specifically concerning basement units not visible from the street, though this complaint is currently listed as not active.

Earlier structural work was conducted in 2012, focusing on foundation repairs and garage ceiling beam installation, with permits filed for approximately $66,000 in structural improvements. The building has maintained its infrastructure with a new roof installed in 2001, and more recently, a complete electrical upgrade in 2019 including installation of new subpanels, lighting, and safety features. The property's maintenance record shows attention to core systems, with multiple HVAC improvements including the replacement of central furnaces and installation of new chimneys. Recent 311 calls from 2021-2024 have primarily concerned street cleaning and parking issues outside of the building, rather than internal building concerns, though there have been multiple reports of parking violations in the vicinity.

Risk rating

How 55-57 Salmon 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.
