Initial analysis

The two-unit residential building at 1823-1825 9th Avenue in San Francisco's Inner Sunset neighborhood, constructed in 1950, is owned by Julia B Gardner and classified as a Flats & Duplex structure. The property has undergone several significant maintenance and compliance events over the past decades, with the most substantial recent activity occurring in late 2018 when multiple housing code violations were identified and subsequently resolved by April 2019. These violations included issues with electrical outlets, sinks, a chimney, fire safety equipment, and ventilation systems. A notable compliance matter from 2011 involved investigating whether an unauthorized unit was created, with documentation showing concerns about kitchen facilities and access routes, though the violation was officially addressed with a permit to remove unauthorized kitchen appliances at a cost of $750.

The building's history shows a pattern of maintenance and repair work primarily focused on kitchen and electrical systems, including multiple permits for kitchen repairs and updates between 1999 and 2011, and a significant electrical service upgrade in 2003. The 2018 violations suggest a period of deferred maintenance prior to resolution, covering various systems including plumbing, electrical, fire safety, and structural elements. Earlier historical records from the 1990s show some building complaints and permit activity, though specific details are limited. The most recent external incident related to the property was a parking violation reported in 2022, which was resolved through standard enforcement procedures.

Risk rating

How 1823-1825 9Th 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.
