Initial analysis

The 4-unit multi-family residential building at 1446 17th Avenue in San Francisco's Inner Sunset neighborhood was constructed in 1947 and is currently owned by Gway Sen Assn. The property has experienced several significant events over its history, with the most recent being a sewage backup incident in December 2023 that was promptly resolved by PUC Sewer Operations. The building underwent a housing inspection in July 2001 that revealed multiple safety and maintenance issues, including requirements for smoke detectors, fire door closers, security features, and gas meter information postings; however, all these violations were successfully abated by August 2001. A heater-related complaint was filed in January 2013, citing intermittent heating issues and window installation problems, though this issue is now listed as not active.

The building's maintenance record shows several external issues in recent years, including three parking violations (two for sidewalk parking and one for driveway blocking) between 2022 and 2023, a streetlight problem in 2015, and various general cleaning requests to Recology in 2013. While these external issues have been addressed as per the respective agencies' reports, the building's internal systems have shown historical concerns, particularly regarding heating and safety equipment compliance in the early 2000s. The property complies with current housing regulations, as evidenced by the resolution of all documented violations, though the age of the building (76 years) warrants standard attention to ongoing maintenance considerations.

Risk rating

How 1446 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.

Neighborhood percentile
