Initial analysis

The four-unit, two-story multi-family residential building at 312 Arguello Blvd, owned by David Helen, has been maintained through several significant repairs and faced multiple safety and maintenance challenges since its construction in 1919. The property has undergone two major roof replacements (1998 and 2021) and received attention to structural concerns, including a $6,000 rear staircase repair in 2023 following termite issues, and recurring stairway repairs for dry rot dating back to 2016. A notable cluster of maintenance problems emerged in early 2022, including inadequate electric heating, electrical wiring concerns in unit #3, and related violations regarding carbon monoxide alarms, window repairs, and lighting issues, all of which were subsequently addressed. The building has experienced several plumbing updates, including water heater replacements in 2019 and 2010, and a sewer trap installation in 2009.

Recent complaints suggest ongoing maintenance challenges, with the most recent about a lack of hot water filed in October 2024. Earlier issues included water leakage problems affecting windows and walls (2022), electrical system concerns (2022), and deteriorating windows (2022). Historical records show the building has been subject to routine safety inspections in 2002, 2008, and 2016, with varying degrees of required follow-up work. The property is also surrounded by typical urban infrastructure issues, as evidenced by multiple 311 calls for tree maintenance, sidewalk concerns, and street cleaning matters from 2021 to 2024.

Risk rating

How 312 Arguello Blvd'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.
