Initial analysis

The two-unit residential building at 28-30 Bache Street in Bernal Heights, owned by Penton Holdings LLC, is a two-story structure built in 1903. The property has experienced several significant safety-related issues in recent years, most notably regarding exterior stairways and balconies. In early 2021, the building faced a violation due to unauthorized reconstruction of stairs in the rear yard, leading to emergency repairs and removal of an unsafe balcony and stairway at the third floor, completed in December 2021 at a cost of $7,000. This safety concern was initially reported in February 2021, with complaints about fire hazards and structural problems. More recently, in January 2023, there was a complaint regarding plumbing issues, including reported raw sewage backups onto the sidewalk, though this complaint is currently listed as not active.

The building's maintenance history shows various improvements and repairs over the years, including a sewer house trap replacement in 2013, water line work in 2009, reroofing in 1997, and aluminum window installation in 1986. Several permits for interior improvements were either completed or canceled, including a canceled permit in 2021 for kitchen and bathroom renovations in unit 28 valued at $20,000. The property has a documented history of illegal unit claims, with complaints in 1996 and 2010 regarding unauthorized units in the basement/backyard and garage, respectively, though these complaints were marked as resolved. Recent 311 calls from 2024 primarily relate to street and sidewalk issues, parking concerns, and debris management, though these are generally not directly related to the building's condition.

Risk rating

How 28-30 Bache 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
