Initial analysis

The two-unit residential building at 72-74 28th Street in Noe Valley, owned by Frank J Farrell & Isabelle, is a two-story flats and duplex structure built in 1900 with significant historical and structural events. The property has faced several serious issues regarding unauthorized unit modifications, most notably a significant violation in 2011 where the ground floor was converted into an illegal unit with a kitchen, bathroom, and living spaces, which triggered multiple safety concerns including unapproved wiring, plumbing installations, inadequate smoke detectors, and improper egress systems. A housing complaint filed in May 2011 reported sewage backup issues, and various permits from 2011-2020 indicate ongoing efforts to address these violations, including the illegal kitchen and bathroom removal in 2011, bathroom repairs, and plumbing work.

The building experienced a fire in 2018 requiring substantial repairs ($15,000), including work on the back wall, porch, and fence. Historical records show earlier structural improvements with shear wall installations completed in 1990, and more recent work includes sewer lateral replacement in 2011 and various compliance inspections through 2020. A tenant buyout occurred in September 2019 for $91,000 involving one tenant. Recent issues include a hazardous materials report for glass on the property in 2019 and multiple maintenance concerns from 2009-2017, including tree root damage to the sidewalk. While many of the building's violations have been abated as of 2020, including those related to unauthorized units, the property's history shows significant prior maintenance and compliance challenges that affected resident safety and building integrity.

Risk rating

How 72-74 28Th 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.
