Initial analysis

Located in San Francisco's Inner Sunset neighborhood, 1747 8th Avenue is a two-story, three-unit multi-family residential building constructed in 1999 and currently owned by the Cheung/Yang Family Trust 20. The building's history features several notable modifications and compliance issues, most significantly a 2006-2008 violation case concerning unauthorized unit conversion and modifications, including an unapproved ground floor kitchen, fireplace installations, and a compromised fire rating due to an unauthorized window addition. This violation was resolved through a 2007 legalization project that included kitchen relocations and electrical work, costing approximately $25,000. The building has undergone various maintenance work, including a recent $9,500 reroofing project in 2023, and historical improvements such as stucco repairs and living area establishment on the ground floor in the late 1990s.

Recent maintenance and quality-of-life issues have predominantly centered around sewer problems, with multiple sewage backup incidents reported between 2021-2022 involving 4-inch sewer vents, which were all resolved through fieldwork. The property has experienced periodic construction activity, with two noise complaints recorded in late 2023 and early 2024, though these permits were properly filed and transferred within the DBI system. While a building violation from 2006 raised serious safety concerns at the time, it's important to note that this violation was officially abated in 2008, and since then, the property has generally complied with permit requirements, as evidenced by the recent completed reroofing project and absence of active violations. The building's maintenance record shows regular upkeep, though the pattern of sewer issues suggests this remains an ongoing infrastructure challenge that has required multiple interventions over recent years.

Risk rating

How 1747 8Th 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.
