Initial analysis

The 2-unit, 3-story residential building at 1440-1442 25th Avenue in the Central Sunset neighborhood, owned by Connie Kong, has undergone several significant improvements and faced some maintenance challenges since its construction in 1926. Most recently, the property has experienced recurring sewer issues, with five reported sewage back-up incidents through the side sewer vent between October and November 2024, indicating potential ongoing plumbing infrastructure problems. The building has seen various improvements over the years, including a complete window replacement project in 2021 costing $5,000 that featured energy-efficient aluminum-clad wood windows with transom glazing, and a substantial $33,666 vinyl siding installation to the back and side walls in 2017. Historical records show earlier maintenance work including garage door replacement in 2004 and water damage repairs to the street-level stairwell that same year, as well as the addition of a storage room with floor drains in 1997 and sidewalk modifications in 1992.

The property has also faced some quality of life issues, as evidenced by multiple 311 calls in 2024, particularly related to parking enforcement matters, including several citations issued for sidewalk parking and driveway blocking. There was one report of an overgrown tree near communication lines in July 2024, though this was addressed under the city's scheduled maintenance plan. The building's documented history includes only one fire incident, recorded as a false alarm. While the property has received various improvements over the years, the recent pattern of sewer-related incidents warrants attention as the most pressing maintenance concern on record.

Risk rating

How 1440-1442 25Th 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.
