Initial analysis

The two-unit multi-family residential building at 1220-1222 20th Street in Potrero Hill, owned by the Halil Turk Trust, was constructed in 1964 as a two-story flats and duplex structure. The building has undergone several maintenance and improvement projects over the years, with the most significant exterior work occurring in 2002 when both the front windows and siding were replaced, with costs of $950 and $2,400 respectively. Electrical system updates include a completed address correction in 2014 and an expired permit for an underground conversion in 2004 valued at $200,000.

The property has experienced recurring issues with graffiti and street cleanliness over the past decade. Most recently, in December 2024, there was an incident involving private residential graffiti that was marked as a duplicate of a similar November incident. The building has also been subject to multiple graffiti incidents between 2023 and 2014, some requiring intervention from city services. Street cleaning issues were documented in 2014 with two separate cases of loose garbage requiring attention from Recology and DPW, though these were successfully resolved. While these events are noteworthy, it's important to note that they primarily relate to building surroundings rather than the structure itself, and there have been no recorded structural or safety-related complaints in recent years.

Risk rating

How 1220-1222 20Th St'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
