Initial analysis

The property at 1246-1248 9th Avenue in the Inner Sunset neighborhood is a 3-story multi-family residential building with commercial space, constructed in 1908 and owned by Catherine Tchen-Kenna. The building has undergone several significant improvements in recent years, most notably a comprehensive window replacement project in 2018 costing $35,800, where 20 windows were installed in lightwells and rear areas, plus 12 front windows were replaced with double-hung wood windows. The commercial space has seen multiple upgrades, including the installation of a new turbofan oven in 2019 and the creation of a self-service coffee bar in 2013, with associated plumbing and electrical work completed in 2014.

The building's history reveals some notable concerns from the past, particularly a series of violations in 2004 related to various maintenance issues including water intrusion, stair repairs, window problems, and potential lead paint hazards, though these were all abated by February 2005. There were also two complaints in 2010 regarding possible illegal unit conversions, though these were resolved and marked as not active. The property has maintained compliance with city regulations since these historical issues, with recent inspections and permits indicating ongoing maintenance and improvements. Recent 311 calls near the property (from 2019-2024) have primarily related to external issues like graffiti, sidewalk cleaning, and tree maintenance, which are standard urban maintenance concerns and not directly related to building conditions. The most recent building inspection recorded was in November 2024, which was completed without noted concerns, suggesting current compliance with building codes.

Risk rating

How 1246-1248 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.
