Initial analysis

The two-unit residential building at 2985-2987 Folsom Street in the Inner Mission, owned by Franklin Tieu, was constructed in 1979 as a two-story flats and duplex structure. The property has undergone several significant maintenance and improvement projects over the years, including a roof replacement in 2013 costing $6,700, electrical system upgrades with a 200-amp underground conversion in 2004, and siding repairs at the rear completed in 1992. However, the building experienced a notable cluster of maintenance issues in mid-2019, with multiple complaints filed between June and July of that year regarding inadequate heating, mold problems, plumbing issues including water pressure problems, interior surface deterioration, and the absence of required smoke and carbon monoxide detectors. These violations were officially abated by September 2019, though they indicated a period of significant tenant dissatisfaction.

The building has had consistent maintenance work performed over its lifetime, with the earliest records showing work completed in 1981 and a basement usage permit from 1983 (which expired). More recently, there has been an ongoing pattern of parking-related complaints in the vicinity of the property, with multiple citations issued between December 2023 and early 2025, though these are external to the building itself. There have also been several reports of garbage and debris issues on or near the property between 2023 and 2024, suggesting some ongoing challenges with exterior maintenance, though these are primarily street cleaning matters rather than direct building maintenance concerns. The most significant historical building-specific complaint dates back to 1994 regarding potential fire safety concerns about cooking in the garage, which was promptly resolved.

Risk rating

How 2985-2987 Folsom 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.
