Initial analysis

The two-unit residential building at 6-8 30th Street in Bernal Heights, owned by Henry Wong, is a 2-story flats/duplex structure built in 1908. The property has undergone several significant renovations and repairs in 2023, including substantial bathroom and kitchen remodels ($95,000), rear stair repairs ($5,500), and subsequent remediation work to address dry rot and code violations ($14,500). Of particular concern is an active building violation from August 2023 regarding unauthorized construction work on the rear stairs that exceeded permitted scope, including complete reframing of two flight stairs with landings and widening of concrete landing areas.

The building's maintenance history shows efforts to address various infrastructure issues, including a 2016 sump pump replacement, 2008 reroofing, and multiple plumbing and electrical upgrades. However, several troubling incidents have been recorded over the years, including a 2016 complaint about illegal plumbing work and sewage issues in the basement, and more recently (2017-2018), problems with flooding in the light well and rodent infestation. Historical records from 1999 indicate various maintenance issues that were subsequently resolved. The property has experienced three fire-related incidents since 2000, though none resulted in civilian injuries, with causes ranging from a natural gas leak to outside rubbish fires.

Risk rating

How 6-8 30Th 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
