Initial analysis

The two-unit residential building at 379 Naples Street in San Francisco's Excelsior neighborhood, owned by Peter Chin and Susan Lai, has a lengthy history of maintenance issues, code violations, and recent development activity. Built in 1900, this two-story flats and duplex structure has undergone various repairs over the years, including balcony repairs, window replacements, and siding work. Notable historical problems include a serious deck collapse and roof leak in 2006, which led to multiple Notices of Violation, and unauthorized construction issues in 2015 involving front stairs. Recent developments indicate significant changes are planned, with permits filed in 2023 for a new three-story building with three dwellings under the SB9 program and for an ADU addition in 2024 including comprehensive interior improvements.

Current active complaints filed in 2024 raise serious concerns about the property's condition and safety, including allegations of electrical wiring code violations and mold issues, as well as concerns about illegal rental units and occupancy limits. The building has a documented history of unauthorized units dating back to 1997, and various complaints have been filed over the years regarding habitability issues, including plumbing problems, structural concerns, and illegal conversions of spaces. Recent permits and planning records show attempts to address some of these issues, including a proposed lot split and new construction under SB-9 guidelines, though concerns remain about historical compliance and current resident conditions. The property has also experienced infrastructure and amenity maintenance issues, as evidenced by multiple repair permits for balconies, stairs, and roofs, with most recent repairs completed in 2023 involving balcony stabilization and window replacement.

Risk rating

How 379 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

Out of 337 buildings in this neighborhood, 276 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.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

12-Month severity forecast
No violation 69.7%
Moderate concern 24.6%
Severe concern 5.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
