Initial analysis

The property at 586-594 Naples Street is a 2-story, 5-unit multi-family residential building located in the Excelsior neighborhood, built in 1916 and currently owned by Richard P.F. Wong and Helen Yu. The building has undergone several significant maintenance and safety inspections over the years, with routine inspections conducted in 2001, 2004, 2007, and 2018 revealing various safety issues that were subsequently addressed. These inspections typically identified concerns with fire safety, building structure, and security, including the need for proper handrails, fire escape clearance, fire extinguisher maintenance, and secure exit doors. A reroofing project was permitted in 1997, though this permit is now expired.

The building has experienced recurring issues with its rear stairs and deck, which required repair work in 1984 and later became a focus of multiple violation notices, particularly regarding handrail requirements. More recent history shows ongoing maintenance activity in the surrounding area, including several 311 calls in 2023-2024 primarily related to parking violations, graffiti, and street cleaning needs. While these external issues do not directly impact building habitability, they provide context about the property's immediate vicinity. The most recent housing inspection (2018) resulted in several fire safety violations being addressed, including garbage receptacle placement and fire extinguisher maintenance, though no subsequent violations have been recorded as of the latest available data.

Risk rating

How 586-594 Naples 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
21th percentile

Out of 337 buildings in this neighborhood, 266 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.

Neighborhood location

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

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 50.5%
Moderate concern 15.8%
Severe concern 33.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
