Initial analysis

The two-story, six-unit apartment building at 1488 Valencia Street in San Francisco's Inner Mission district, owned by Wong Don D, has a mixed history of maintenance and safety issues dating back to at least 2001. Most recently, in 2023, the building underwent reroofing work valued at $20,000, though this has been accompanied by ongoing concerns about hazardous electrical wiring documented in a June 2023 complaint that remains active as of October 2023. The building's safety record shows several significant fire safety violations, particularly in 2001 and 2004, including issues with egress obstructions, fire sprinklers, fire escape maintenance, and alarm systems, all of which were officially abated by March 2001 but suggest a pattern of fire safety concerns. More recent fire-related incidents include two malfunctioning alarm system activations in 2023, though with no civilian injuries recorded. The property has also had multiple routine inspections conducted in 2001, 2004, and 2010, as well as two fire safety violations in 2020 related to alarm systems and exit maintenance, though these were documented as corrected.

Outside of safety concerns, the building has faced various maintenance issues, with the most recent complaint from December 2024 citing multiple interior problems including a broken front gate, screen door, and wall damage. The property has experienced periodic issues with garbage collection, sidewalk cleaning, and all-weather maintenance, as evidenced by multiple 311 calls between 2018 and 2023, including a notable instance of blocked exit common areas in July 2020 that resulted in a violation. While older violations from 2001 and 2004 suggest historical safety concerns, it is worth noting that these were officially abated, and more recent safety inspections have shown some improvements, though the active electrical wiring complaint from 2023 indicates that some maintenance issues persist.

Risk rating

How 1488 Valencia 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.
