Initial analysis

The two-unit residential building at 2146-2148 19th Avenue, located in San Francisco's Inner Parkside neighborhood, is a two-story flats and duplex structure built in 1946 and currently owned by Sophie Yu. The building has undergone several significant maintenance and improvement projects over the years, with the most recent being a complete re-roofing in 2020 costing $12,000. The property has seen consistent updates to maintain safety and modern standards, including a major electrical system upgrade in 2002 to a 200-amp service with three meters and multiple breakers, and the addition of a basement laundry room in 2005. Historical maintenance records show attention to structural elements, with wooden balcony repairs for dry-rot completed in 1989, and the installation of aluminum windows in 1983 and 1986.

The building's history includes one notable complaint regarding backyard access obstruction due to a fence installation in 2004, though this issue was promptly abated within three weeks. A significant infrastructure incident occurred in June 2012, when there were two reports of a sewage backup problem that required attention from the Public Utilities Commission (PUC) Sewer Operations, involving fresh water flow issues from a service box. Recent exterior maintenance has included attention to pavement defects near the property in 2020. The property has experienced typical urban residential challenges, such as parking enforcement issues and abandoned vehicle concerns in the surrounding area, though these are not directly related to the building's condition or habitability. The maintenance history suggests regular upkeep and responsive management, with no recorded safety violations or persistent maintenance issues in recent years.

Risk rating

How 2146-2148 19Th 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.
