Initial analysis

The Johnson Family Trust owns this two-unit, two-story multi-family residential building located at 527-535 Wisconsin Street in Potrero Hill, which was originally constructed in 1988. The property has undergone several significant improvements over the years, with the most recent being a completed reroofing project in January 2024 costing $20,000. In 2018, major infrastructure upgrades were completed including both sewer lateral replacement and bathroom installation in the family room, demonstrating ongoing maintenance of essential systems. Earlier improvements include energy-efficient upgrades such as window sash replacements in 2014 (eight wood-clad windows with U-factor .40) and the installation of a 3.375 kW solar PV system in 2009. The building's maintenance history shows regular upkeep, including water heater replacement in 2014 and various window-related work in the early 1990s.

The property has had some planning considerations, most notably a proposed but disapproved exception to rear yard requirements for a two-story deck and stair structure. This proposal, which went through several reviews in the early 1990s, was ultimately not permitted. The building's history indicates responsible maintenance and upgrades by the ownership, with no significant safety or resident experience concerns documented in the available records. The most recent building improvements, including the 2024 reroofing project, suggest ongoing commitment to maintaining the property's infrastructure and systems.

Risk rating

How 527-535 Wisconsin 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 726 buildings in this neighborhood, 22 are predicted to be safer.
