Initial analysis

The two-unit residential building at 679 18th Avenue, owned by Albert and Hazel Fong, was constructed in 1987 following the demolition of a single-family dwelling in March 1986. The property has experienced recurring sewer issues in recent years, with multiple sewage backup incidents documented between July 2023 and September 2024, all involving the 4-inch sewer vent and side sewer vent areas. These sewer problems are the most pressing current concern, with four distinct incidents recorded in 2024 alone, including two cases of sewage backup discharge on September 2-8, 2024, and a sewer backup incident on October 9, 2023.

The building's history includes a significant structural safety concern in 2004, when a wooden retaining wall and fence at the rear of the property were reported as deteriorated and in danger of collapse, leading to a Notice of Violation (NOV) which was addressed through a repair permit costing $3,000, though this permit is now listed as expired. While this violation was ultimately abated in 2012, it marked a notable period of safety concern. The property has also had several instances of general maintenance and cleanliness issues in recent years, including multiple reports of loose garbage (2020-2021), a Christmas tree removal request (2021), and an incident of sidewalk parking (2020) which resulted in a citation. A sewer odor complaint was recorded in December 2020, suggesting ongoing drainage system challenges have been a recurring theme for this property.

Risk rating

How 679 18Th 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

Out of 2250 buildings in this neighborhood, 495 are predicted to be safer.
