Initial analysis

The three-story multi-family residential building at 209-211 Arkansas Street in Potrero Hill, owned by James J. Diehl and Brenda Hefti, consists of two units and was constructed in 1978. The property has undergone significant improvements over the past decade, with the most recent major work including mini-split installation (2023), foundation drainage work (2022), and several plumbing and electrical upgrades. Notable improvements include a substantial 2016 renovation adding interior stairs, a new bedroom and bathroom in unit 209, and a lightwell pop-out in unit 211 (costing $80,000), followed by window replacements in 2016 and a kitchen remodel in 2020. The building has received proper attention to infrastructure, with the installation of radiant heating systems and various plumbing upgrades including bathroom renovations and drainage improvements.

The property has experienced some regulatory scrutiny, with two complaints filed regarding unpermitted work - one in 2022 and another in 2008 concerning unauthorized roof deck construction. However, these issues were addressed and are no longer active. Recent activity around the building has primarily involved routine municipal services, including several street cleaning and sidewalk maintenance requests in 2022-2024. Current pending issues include a sidewalk defect reported in September 2024. The building's maintenance record shows regular updates to essential systems and proactive improvements, with most recent permits focusing on comfort and efficiency upgrades rather than structural changes. The property has maintained compliance with building codes following the resolution of past complaints, and all major system updates have been properly permitted and documented through appropriate channels.

Risk rating

How 209-211 Arkansas 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
