Initial analysis

The two-story, four-unit apartment building at 1769-1777 Folsom Street, built in 1911 and currently owned by the Gan Kim Trust, has experienced several significant maintenance and safety issues over the past decade. Most notably, in April 2019, the building received multiple notices of violation (NOV) related to safety concerns, including inadequate smoke detection systems, handrail and stair repairs, security requirements, inadequate lighting, electrical issues, and lead paint hazards. These violations were abated by July 2019 through various repairs, including handrail repairs and stair step improvements. The building faced further challenges in 2021 with heating system problems and peeling paint issues, which were eventually resolved. An incident in July 2020 involved damage to the storefront from a vehicle crash, requiring repairs to the security door, glass door, flooring, and storefront siding, completed at a cost of $20,000.

The property has undergone various mechanical system upgrades, including water heater replacements in 2021, electrical improvements such as new baseboard heaters, and plumbing work addressing furnace repairs and leaks. Several fire code violations were recorded between 2016 and 2022, including instances of operating without proper permits and multiple fire code violations in 2020, though these were subsequently addressed. Recent records from late 2024 indicate ongoing maintenance challenges, with multiple 311 calls regarding pavement defects, graffiti, and waste management issues around the property.

Risk rating

How 1769-1777 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.

Neighborhood percentile
