Initial analysis

The two-unit residential building at 2208 23rd Street in Potrero Hill is a two-story flats and duplex structure built in 1918, currently owned by the Amy Cheng Trust. The building's maintenance history shows minimal major work, with the most significant repair occurring in 1996 when $12,000 was spent on replacing siding, repairing hardwood floors, and addressing wall issues. Two street space permits were issued in early 2014 for nominal costs of $1 each.

The property has experienced some recurring infrastructure challenges in recent years, with two documented sewage discharge incidents from the side sewer vent in 2024-2025 (September 2024 and January 2025), though both cases were resolved through field work. The building has also been affected by multiple instances of graffiti, with three separate incidents reported in early 2025 and several others throughout 2024, including a July 2024 case involving a residential building. Additional environmental concerns have been documented, including a July 2024 incident involving a lifted sidewalk. A defaced parking sign was reported in June 2024 and remains open as of the report date. A combustible materials complaint was filed in February 2018, though this was investigated and found to have no merit by April 2018. While these incidents reflect various maintenance and environmental challenges in the immediate vicinity, there are no recorded incidents affecting the building's structural integrity or safety systems since 2018.

Risk rating

How 2208 23Rd 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.
