Initial analysis

The three-unit, three-story multi-family residential building at 1481-1485 Washington Street in Nob Hill, owned by Adrian Wong, was constructed in 1911 and has undergone several significant maintenance and compliance updates over the years. Most notably, in mid-2015, the property faced multiple code violations that required attention to safety systems, including ventilation in penthouses, water heater strapping, roof access door repairs, and smoke detector installation requirements. These violations, all addressed by April 2016, were documented through a routine inspection and subsequently resolved, with evidence of proper corrective action taken through building and plumbing permits. Historical maintenance records show earlier improvements, including a kitchen and bathroom remodeling in 1993 and code compliance work in 1985. The building's roofing system was last addressed in 1995, though that permit has since expired.

Recent activity around the property mainly involves external urban issues, with multiple 311 calls related to pavement defects in 2023, and some street cleaning matters between 2018 and 2021, though these are more related to the neighborhood than the building itself. The property has maintained compliance with major housing codes since addressing the 2015 violations, with no active building violations or complaints on record as of the current date. The building's documented history shows a pattern of routine maintenance and responsiveness to regulatory requirements, with all recent significant issues having been properly resolved through appropriate permitting and inspections.

Risk rating

How 1481-1485 Washington 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.

Neighborhood percentile
