Initial analysis

The two-unit residential building at 667-669 Naples Street in San Francisco's Excelsior neighborhood is a two-story flats and duplex structure built in 1900, currently owned by Chia Chung & Yee Pang Wong Re. The property has undergone several significant improvements over the years, with the most recent substantial work occurring in 2016 when the kitchen was renovated, including cabinet replacement, countertop installation, sink replacement, and electrical upgrades, with costs totaling approximately $12,000. The building has experienced some notable issues requiring regulatory attention, including a 2007 violation for unauthorized conversion of a laundry room into a cooking facility, which was resolved by March 2008, and a 2021 complaint regarding unauthorized construction of an in-law unit and multiple rooms, though this was marked as not active. The property has had recurring maintenance needs, particularly regarding the backyard deck (repaired in 2010) and sewer systems, with two sewage discharge incidents reported in October 2024.

Recent maintenance and repair history includes work on various building systems, with permits issued for reroofing in 2006 (and 1993), deck repairs, and kitchen modifications. The property is currently experiencing some infrastructure challenges, with open issues reported in late 2024 including sidewalk defects (root-related lifting), tree maintenance concerns, and recent sewage backup incidents. There is a history of enforcement actions for parking violations affecting the sidewalk area, with multiple citations issued in late 2024. While the building has undergone various improvements and repairs over its history, the recent pattern of maintenance issues and infrastructure concerns, particularly regarding sewer systems and exterior features, may warrant attention, though these issues are being addressed through appropriate city channels.

Risk rating

How 667-669 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.
