Initial analysis

The Fair Oaks Apartments, located at 799 Oak Street in Hayes Valley, is a four-story, 20-unit multi-family residential building constructed in 1908. The building has undergone several significant safety-related improvements in recent years, most notably a comprehensive fire alarm system upgrade in 2022 costing $55,000, which included replacing the fire alarm panel motherboard, installing new low-frequency sounders, and updating initiating devices for compatibility. The building's fire safety history reveals recurring alarm system issues between 2015 and 2023, with multiple incidents of system malfunctions and false alarms, though no civilian injuries have been reported in any fire-related incidents. A notable cluster of fire safety violations was recorded in October 2019, including issues with emergency lighting, fire protection equipment, and sprinkler system maintenance, all of which were subsequently abated.

The building has undergone several structural and maintenance projects over the past decade, including the replacement of badly rusted parts of the first-floor fire escape balcony in 2016, roof work in 2009, and foundation work in 2011. More recently, in August 2023, multiple active violations were filed regarding compliance affidavits and fire escape maintenance, which remain unresolved as of the latest available data. The property has maintained an active record of addressing maintenance issues, as evidenced by the prompt resolution of a 2021 complaint about exterior molding, though some current open issues related to fire escape maintenance and compliance documentation remain a concern. The building's plumbing infrastructure has also seen attention, with a complete sewer line and house trap replacement project completed in 2010, demonstrating ongoing investment in critical systems.

Risk rating

How 799 Oak 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

Out of 1027 buildings in this neighborhood, 852 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 36.7%
Moderate concern 39.9%
Severe concern 23.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
