Initial analysis

The two-story, four-unit apartment building at 1500 11th Avenue in the Inner Sunset, owned by Rong Richard & Wong Isabel, was constructed in 1948 and has undergone several significant upgrades over the years. Most notably, a comprehensive electrical system upgrade was completed in 2004, including the installation of a 200-amp service upgrade, individual unit meters, and new circuit breaker panels. The building has received regular maintenance attention, including reroofing work in 2005 ($8,800) and various building and safety improvements. A series of building violations were recorded in 2002 related to fire safety and structural issues, including problems with stairs, fire extinguishers, smoke detectors, and fireproofing, all of which were resolved by May 2002. Another routine safety inspection in 2011 resulted in several fire safety requirements being addressed.

Recent maintenance issues have been minimal, though there have been recurring problems with vehicles blocking the driveway, with multiple citations issued between 2019 and 2024. In 2022, there were reports of a sewage backup that was subsequently resolved by PUC Sewer Operations. Two significant structural improvements were made in the early 1980s, including a building code compliance upgrade in 1984. The property's maintenance history shows a pattern of responding to both routine inspections and specific complaints in a timely manner, with most issues being resolved within a reasonable timeframe. The most recent building-related service call was regarding a sewage issue in March 2022, which was promptly addressed.

Risk rating

How 1500 11Th 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 1493 buildings in this neighborhood, 1135 are predicted to be safer.
