Initial analysis

The Wong Family Trust's 2-story, 6-unit multi-family residential building at 1266 17th Avenue in the Inner Sunset, constructed in 1964, has undergone several significant improvements over the past decades, with particular attention to safety and maintenance. Most recently, in August 2024, the building began upgrading its fire alarm system to comply with San Francisco Fire Code requirements, including the installation of low-frequency sounders in sleeping areas and updating all existing devices to be compatible with a new fire alarm control panel. The building successfully completed its mandatory soft-story seismic retrofit (Tier 3) work, which included the installation of moment frames on the ground floor, demonstrating compliance with San Francisco's seismic safety requirements. Earlier improvements included exterior maintenance in 2018 with siding replacement and window retrofitting, and plumbing upgrades in 2010 involving bathroom fixtures.

The building has experienced several maintenance and safety-related issues in its history, most notably a series of fire safety violations in 2001 that were promptly addressed within one month, including problems with fire-proofing materials, smoke enclosure door closers, and fire extinguisher maintenance. Two significant water-related incidents were recorded in 2002, involving leaks in bathrooms, a lobby, and a garage area, though these were resolved within a reasonable timeframe. The property has undergone regular routine inspections by Housing Inspection Services in 2001, 2009, and 2018, as well as some street space-related permits in 2018 and 2019. While there have been several 311 calls regarding the property location, these were primarily related to issues outside the building's direct management, such as abandoned vehicles and street litter concerns, rather than building-specific problems.

Risk rating

How 1266 17Th Ave'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.
