Initial analysis

The building at 1246 18th Street in Potrero Hill is a one-story multi-family residential property owned by the Perata Family Trust, containing three units and constructed in 1911. The property has undergone several significant improvements over the past decades, with the most substantial renovations occurring in 2007, including the installation of energy-efficient windows (six windows, two bow windows, and four double-hung), a complete kitchen remodel with new cabinets and appliances, electrical upgrades including a new 300-amp service, and a sewer line replacement. Earlier improvements included exterior enhancements such as an awning installation in 2003-2004 and a wall modification in 1995. A reroofing project was permitted in 1998, though records show its status as expired.

The street-facing areas around the building have experienced recurring maintenance issues in recent years, particularly evident from the 311 call records. Between January 2024 and October 2024, there have been multiple reports of garbage, debris, and street cleaning needs, with six separate sanitation-related incidents recorded in June 2024 alone. Two instances of graffiti were reported in 2024, one being offensive (still open as of June 2022) and another in January 2024 that was administratively closed due to technical issues. A sewer-related flooding incident was reported and resolved in March 2023, which was noted to be on the street rather than directly related to the building infrastructure. While the building itself has received consistent maintenance and upgrades through the years, the surrounding street and sidewalk areas appear to require ongoing attention based on the frequency of reported issues.

Risk rating

How 1246 18Th 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
