Initial analysis

The three-unit multi-family residential building at 2640-2642 McAllister Street in Lone Mountain, built in 1909, has experienced several significant maintenance and safety issues over its history. The most recent major concern was filed in December 2021, involving electrical work done by the landlord and subsequent water leakage and mold problems in the bathroom. A routine safety inspection in November 2016 revealed multiple violations, including an obstructed egress from back stairs, missing fire extinguishers, absent carbon monoxide alarms, and the need for wood stair repairs, though all these violations were abated by January 2017. The building's maintenance history shows consistent attention to roofing and stair structures, with a reroofing project completed in 2010 costing $10,600, and various stair repairs conducted in 2006 and 1995.

Earlier concerns included a 2006 complaint about mold in closets, water damage in the hallway, and rotting back stairs, which was resolved by July 2006. Multiple routine inspections between 2003 and 2016 identified various safety issues, particularly regarding fire safety equipment, stair conditions, and drainage systems, though all were eventually resolved. The most recent infrastructure-related incident was a sewage backup discharge reported in July 2024, which was promptly addressed by PUC Sewer Operations. While the building has experienced several maintenance and safety issues over the years, most have been addressed through proper channels, with the exception of the 2021 electrical and water-related concerns which were still marked as not active as of October 2023. The property has also recorded several parking-related complaints in the vicinity, though these are external to the building's immediate conditions.

Risk rating

How 2640-2642 Mcallister 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
