Initial analysis

The property at 3921-3925 24th Street is a three-story mixed-use building constructed in 1910, containing four residential units and ground-floor retail space, currently owned by Alessandro Bifulco. The building has undergone various maintenance and improvement projects over the past decade, including a significant retaining wall replacement project in 2018 at the rear property line, which was approved and remains active, and various unit upgrades such as kitchen cabinet replacement (2015), bathroom remodeling (2013), and roofing work (2011). Several building violations were recorded between 2002 and 2015, primarily related to fire safety issues such as fire extinguisher maintenance and egress obstructions, though all these violations were resolved by January 2003.

The property has experienced some concerning incidents in recent years, most notably a complaint in June 2019 regarding allegedly unauthorized construction work affecting electrical and plumbing systems, which was investigated but ultimately marked as not active. A similar situation occurred in March 2015 concerning suspected unpermitted construction work on a rear balcony. The building underwent a routine housing inspection in 2015, and there is a record of a withdrawn permit application to legalize a rear deck on the third floor. Approximately $40,000 worth of documented improvements have been made to the property since 2011, including structural work, bathroom renovations, and parking-related improvements. The property has also been subject to various municipal service calls in the surrounding area, particularly for parking meter issues and general street cleaning, though these are not directly related to the building's condition or management.

Risk rating

How 3921-3925 24Th 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.
