Initial analysis

The two-unit multi-family residential building at 397 Arlington Street in Glen Park, owned by the John F Brown Trust, is a one-story flats/duplex structure built in 1905. The property has undergone several significant improvements over the years, with the most recent major work being plumbing upgrades in 2017, including sewer lateral and house trap replacement. The building's maintenance history shows attention to structural integrity, with multiple dry rot repairs completed between 2000 and 2014, including siding repairs in 2014 and 2013, and a substantial bathroom addition project in 2001 (which expired but was later permit renewed). The property has also seen several other notable improvements, including the installation of a photovoltaic system with battery backup in 2002 ($20,000), front stair rebuilding projects in 2001 and 2003, and the construction of a garage extension with utility room and roof deck as part of an approved variance.

Recent activity around the property has primarily consisted of 311 calls related to street maintenance and parking issues, with multiple reports of abandoned furniture, debris, and parking violations between 2024 and 2025. The most recent construction work on record was completed in 2017, suggesting that there have been no major structural changes or improvements in the past several years. The building's permit history indicates regular maintenance and timely addressing of building envelope issues, though some permits from 2001 for bathroom addition and front stair work were originally filed in 2001 but later expired. The property has maintained compliance with building codes and requirements, as evidenced by the successful completion of multiple repair projects and improvements over its history.

Risk rating

How 397 Arlington 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
