Initial analysis

The two-family residential building at 879 Kansas Street in Potrero Hill, owned by the Samuel W Blattner Revoc Tru, has undergone several significant improvements since its construction in 1987. Most recently, in late 2024, the property has seen substantial renovations including the installation of recessed lighting, bathroom remodeling in both guest and primary bathrooms, and electrical upgrades including new can lights, plug replacements, light fixture installations, and removal of intercom systems. A plumbing upgrade is also in progress, involving shower/tub valve replacements and fixture installations. The building's maintenance history includes a complete reroofing project in 2006 that cost $7,000.

The property has experienced recurring issues with parking enforcement, particularly regarding sidewalk parking, with multiple citations issued between 2023 and 2024, though most recent complaints were resolved with officials unable to locate the offending vehicles. In 2024, there was one open 311 call regarding a sidewalk defect, though the exact nature of this issue is not specified. Earlier records show the demolition of a single-family dwelling in 1986 followed by the construction of the current two-family dwelling on the same site. A malfunctioning alarm system was recorded as a fire incident, but no injuries were reported.

Risk rating

How 879 Kansas 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.
