Initial analysis

The two-unit residential building at 51 Naples Street in the Excelsior neighborhood, owned by Yu Joel Lei Ping, was constructed in 1920 and is classified as a Flats & Duplex structure. The property's history reveals a significant event in 2004 when a complaint was filed regarding an illegal ground-level unit, though this issue was promptly addressed within approximately one week. More recently, the building has experienced multiple parking-related incidents, particularly between October and December 2024, with at least one citation issued for illegal sidewalk parking. There were also two street-related issues documented in 2024: a garbage and debris complaint involving electronics in October, and a driveway-related issue with a 10-foot measurement noted in July.

The property's permit history shows a single building permit from 1982, though the specific nature of this permit is not detailed in the provided data. A historical fire complaint from 2005 regarding weeds and grass was filed but was determined to have no merit within three months. While the building appears to have maintained a relatively low number of complaints since its construction, the concentration of parking-related issues in late 2024 may indicate ongoing challenges in this area.

Risk rating

How 51 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
66th percentile

Out of 337 buildings in this neighborhood, 115 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.

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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 71.1%
Moderate concern 16.1%
Severe concern 12.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
