Initial analysis

The 3-story multi-family residential building at 351-357 Oak Street in Hayes Valley, owned by the Lyons Family Trust, is a 4-unit structure built in 1922. The property has undergone several significant renovations over the past decade, with the most recent improvement being a kitchen renovation in December 2021 that included cabinet and countertop replacement, along with sink and faucet updates, completed at a cost of $10,000. Between 2011 and 2013, the building received substantial window upgrades, with multiple permits showing the replacement of 12 windows, both visible and non-visible from the street, with wood-clad aluminum windows. Other improvements have included a furnace replacement project in 2014 (which shows as expired) and associated plumbing and electrical work during the 2021 kitchen renovation.

The building's recent history shows no major internal complaints or violations, with only one routine housing inspection recorded in 2008 that was abated the same day. A series of 311 calls from 2021 to 2024 have primarily concerned external issues such as street cleaning, illegal parking, and tree maintenance, which are not directly related to the building's condition or services. These external matters included several instances of illegal parking (three citations issued), multiple general cleaning requests, and one tree pruning request, suggesting ongoing community maintenance needs in the building's immediate vicinity. The property's maintenance record shows regular upkeep of both interior and exterior elements, with significant investments in updating windows and kitchen facilities, though the status of the 2014 furnace replacement work remains uncertain due to its expired permit status.

Risk rating

How 351-357 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.

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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 43.0%
Moderate concern 25.0%
Severe concern 32.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
