Initial analysis

The two-unit residential building at 41 Sussex Street in Glen Park, owned by Randall W. Wonzer, is a 2-story flats and duplex structure built in 1908. The building has undergone several significant improvements over the past two decades, including the installation of a comprehensive fire safety system with six sprinklers and a new solar electric system in 2006. Major renovations in 2005 included deck repairs, addition of second egress from the upper unit, horizontal expansion, and seismic upgrades, while more recent work has focused on addressing multiple fire code violations in 2022, though inspectors gained "No Access to Building." The property has experienced recurring concerns about unauthorized units, with complaints filed in 2021 regarding a potential unpermitted dwelling unit with gas stove and full bathroom, and in 2008 about an illegal garage unit - both complaints were eventually marked as "Not Active."

In 2024, the building faced multiple infrastructure challenges, including sewer-related flooding issues on the property in August and March, and a damaged tree with hanging limb in September. The property has also been the subject of recent health and safety concerns, with an active complaint filed in December 2024 regarding construction practices and lead dust containment, and environmental health complaints in October 2023. The building's systems and infrastructure have received attention over the years, including mechanical replacements and electrical system upgrades in 2006, but there have been periodic maintenance and safety concerns, as evidenced by the 2015 complaint about an open vacant building (no merit found) and the 1994 roofing work permit which has since expired. The property has also experienced some public space issues, including illegal parking complaints and pavement defects in the surrounding area, with one incident in July 2023 linking to flooding that affected multiple properties.

Risk rating

How 41 Sussex 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
27th percentile

Out of 364 buildings in this neighborhood, 266 are predicted to be safer.
