Initial analysis

The two-unit residential building at 339-341 Connecticut Street in Potrero Hill, owned by Juan-tomas Rehbock & Akemi, is a two-story flats and duplex structure built in 1910. The property has undergone several significant improvements over the past decade, with the most recent being a window replacement project completed in December 2023 at a cost of nearly $20,000. In 2022, the building received a new roof and solar panel installation, including infrastructure upgrades with 10 modules rated at 3.60 kW. Earlier renovations included kitchen upgrades in 2014 (including cabinet and countertop replacement, new outlets, and lighting), electrical rewiring of the upper unit, and garage electrical system improvements. The building has also seen structural maintenance work, such as rear deck repairs in 1991 and kitchen remodeling in 1987.

A series of parking enforcement issues have been documented in recent years, with multiple citations issued for blocked driveways between 2022 and 2025, with five instances requiring citations in 2023-2024 alone. The property has maintained compliance with building regulations, as evidenced by the successful completion of numerous permits, including the recent installation of non-street-visible windows in 2023 and previous works like vinyl siding installation in 2007 and various electrical system upgrades. The regular maintenance and upgrading of systems suggest active property management, though the recurring parking issues indicate ongoing challenges with driveway access that have required multiple enforcement actions.

Risk rating

How 339-341 Connecticut 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.
