Initial analysis

The property at 20 Arlington Street in Glen Park is a 2-story, 4-unit multi-family residential building constructed in 1975, currently owned by Andrus Partners LLC. The building has undergone numerous renovation and maintenance projects over the past two decades, with significant work focusing on exterior improvements including multiple siding replacements (2011-2014), window upgrades (2014), and stucco repairs (2012). Several building violations related to unauthorized construction and habitability issues have been recorded, including a 2004 complaint about using storage rooms as habitable space and various complaints between 2008-2014 regarding unpermitted construction work, particularly involving bathroom remodels and siding replacements. The most recent building permit of note, filed in 2016 to enclose a light well for kitchen pantry and bathroom modifications, was ultimately cancelled.

The building's maintenance history shows regular upkeep, with completed work including bathroom renovations (2011, 2008), plumbing upgrades, and electrical improvements. Of particular note is the building's status as a residential care facility, with records indicating attempts to expand its capacity from 6 to 15 residents, including a proposal to add two third-floor dwelling units. Recent activity in the vicinity (2024) has primarily involved public infrastructure issues such as sidewalk blockages and graffiti, though these are external to the building itself. The property has maintained compliance with most regulatory requirements, with most violations being resolved through subsequent permits and corrections, though there have been recurring issues with unauthorized construction work leading to multiple complaints and violation citations over the years.

Risk rating

How 20 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

Out of 364 buildings in this neighborhood, 280 are predicted to be safer.
