Initial analysis

The 12-unit apartment building at 41 Octavia Street in Hayes Valley, owned by Carol Wang, is a 4-story, 1904 structure that has undergone several significant improvements and faced various maintenance challenges over the years. Most notably, the building completed a $70,000 mandatory soft-story retrofit in 2018 to comply with seismic safety requirements. Recent building maintenance includes a sewer lateral replacement in 2018 and several street space permits in 2018-2019. The building has a documented history of fire safety violations and concerns, with issues related to the alarm system, sprinkler system, and fire escapes being recurring themes. December 2024 violations noted issues with the alarm system, while 2019 violations included problems with fire extinguisher servicing and sprinkler maintenance. The building has also experienced multiple fire code violations that were subsequently corrected, including blocked exits and extinguisher issues in 2018.

The property has undergone various infrastructure upgrades, including electrical panel replacements, domestic hot water boiler replacement in 2013, and extensive electrical work in 2003. Several building complaints from recent years (2023-2024) highlight ongoing maintenance concerns, including issues with gas utility shutoff tools, fire escape ladders, and compliance documentation. Historical complaints from 2001-2002 revealed more serious concerns, including inadequate heating systems and unauthorised modifications to the building's infrastructure. The building's history also shows attention to lead paint hazards and other safety concerns during inspections, with violations typically being abated within reasonable timeframes. Recent activity indicates continued attention to fire safety systems, with violations being promptly addressed, though there are currently multiple open encampment-related 311 calls from January 2025 indicating some external area management issues.

Risk rating

How 41 Octavia 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
