Initial analysis

The three-story multi-family residential building at 2309-2313 25th Street in Potrero Hill, constructed in 1906, has undergone several significant improvements and faced various maintenance challenges over the years. The property, consisting of three units, was officially designated with three addresses in 2010 when #2313 was added to complete the block's numbering. Major renovations include a $165,000 roof reconstruction in 1999 (replacing 2/3 rafters and roof sheathing), an $80,000 basement conversion and retaining wall project in 2001, and a $10,000 deck and stair replacement in 2002. In 2010, the building faced multiple fire safety violations that were all resolved by September 2010, including requirements to provide fire extinguishers and repair stairs, though these issues required some re-inspections and created temporary safety concerns during the process.

Recent issues have centered primarily around sewer problems, with three documented sewage backup incidents affecting the 4-inch sewer vent (most recently in December 2023), suggesting an ongoing infrastructure challenge. The property also experienced a gas leak that required repair in 2011, though this was promptly addressed. The building's surroundings have required regular maintenance attention, evidenced by multiple street cleaning and general maintenance calls through the 311 system, with the most recent being a sidewalk blockage in July 2023 during construction work. While these maintenance issues have generally been addressed promptly, the recurring nature of the sewer problems might warrant monitoring of future maintenance requirements.

Risk rating

How 2309-2313 25Th 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.
