Initial analysis

The property at 1243 17th Avenue is a 2-unit, 2-story multi-family residential building located in San Francisco's Inner Sunset neighborhood. Built in 1939 and currently owned by the Deborah Quock Living Trust, this flats/duplex structure has a documented history of several maintenance and safety-related issues over the past five years. Most notably, there are recurring concerns about tree-related infrastructure, with an open report from July 2024 regarding sidewalk damage from tree roots and a December 2023 report about a damaged tree that was resolved with "Nothing found" upon inspection. The building's most significant structural improvement on record is a reroofing project completed in 1996.

The property's maintenance history includes periodic street cleaning needs, with reports of loose garbage in 2018, 2020, and most recently in January 2023. While these issues were resolved, they indicate some concerns about neighborhood cleanliness in the vicinity of the building. There was also one instance of offensive graffiti in 2019 that was removed, and two separate incidents in July 2020 involving illegal postings and a defaced parking sign, both of which were addressed by city services. More recent issues primarily involve parking concerns, with two incidents reported in 2024 - one regarding sidewalk parking and another about driveway blocking, the latter resulting in a citation. Of particular note is the persistent difficulty in resolving tree-related infrastructure issues, with both the sidewalk defect report from July 2024 and the earlier damaged tree report suggesting ongoing challenges with the building's natural surroundings.

Risk rating

How 1243 17Th 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.
