Initial analysis

The 16-unit, 1925 two-story apartment building at 566 Fell Street in Hayes Valley, owned by the Nina Geneson Living Trust, has undergone significant recent upgrades and modifications. Most notably, between 2019-2021, the property added three Accessory Dwelling Units (ADUs) at the ground floor, requiring extensive infrastructure improvements including new fire sprinkler systems, a fire alarm monitoring system, and complete electrical rewiring of multiple units. The building has received attention to safety matters, with fire alarm and exit maintenance issues reported and corrected between 2017-2022, and completed its soft-story retrofit requirements. Numerous tenant buyouts were recorded between 2017-2019, totaling $191,500 for six tenants, indicating ongoing unit turnover and building upgrades.

Historical records show the building's recent focus on safety improvements, including multiple fire system upgrades, while previous building complaints from 2012-2018 addressed various maintenance issues including heating, damaged walls and ceilings, and smoke detection systems, all of which were abated. Two complaints were filed in August 2021 regarding an allegedly illegal unit (Unit B) with suspected window violations, though these complaints are currently listed as not active. The property has experienced several routine safety inspections and responses to complaints over the years, including electrical rewiring projects in 2015-2016 to update the building's infrastructure. The recent completion of significant improvements such as the ADU conversion project, fire safety upgrades, and the building's designation as a completed soft-story retrofit suggests ongoing investment in building safety and modernization, though the presence of past violations and complaints indicates historical maintenance challenges have existed.

Risk rating

How 566 Fell 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.
