Initial analysis

The three-story duplex at 2525 Lyon Street in Cow Hollow, built in 1922 and currently owned by the Richard G Fabian Living Trust, has undergone several significant improvements and maintenance work over the years. Most recently, in May 2024, a comprehensive bathroom renovation was completed at a cost of $40,000, including new fixtures, electrical work, and insulation upgrades. This follows the installation of a residential elevator in 2015-2016, which included mechanical and safety improvements such as updated fire escape modifications. The building has experienced some structural and pest challenges in the past, notably in 1989-1993 when termite damage required multiple repairs, including framing and sheathing replacement, while more recent maintenance includes regular water heater replacements, with the most recent occurring in January 2022.

The property has had minimal fire safety incidents, with recorded smoke detector activations and one building fire that were all classified as unintentional, with no civilian injuries reported. The building's site has seen various infrastructure and environmental maintenance activities throughout 2024, including tree maintenance, sewer vent repairs, and several sidewalk-related issues, though most of these have been resolved or transferred to appropriate authorities. Recent 311 calls indicate ongoing urban environmental management needs, such as landscaping and sewer maintenance, while planning records show historical approvals for significant improvements including third-floor extensions, deck replacements, and new fire escapes, demonstrating the property has been properly maintained and updated to meet current codes and standards over its long history.

Risk rating

How 2525 Lyon 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
91th percentile

Out of 861 buildings in this neighborhood, 77 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.

Building age

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 81.9%
Moderate concern 12.8%
Severe concern 5.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
