Initial analysis

The property at 1142-1144 18th Street in Potrero Hill is a two-unit, two-story multi-family residential building constructed in 1902, currently owned by Patrick C Crowley under a revocable trust established in 2008. The building has undergone several significant renovations and faced multiple safety compliance issues, particularly in 2000 when multiple violations were filed regarding fire safety, egress, and handrails that were subsequently abated by November 2000. In 2002, multiple permits were filed or issued for exterior work, including removal of stucco and repair/painting of existing redwood siding, as well as replacement of front entry stairs, though these permits have since expired.

The most recent maintenance concern is a collapsed sidewalk reported in August 2024, which remains an open issue. The property has had several street-level incidents recorded through 311 calls, including the presence of medical waste (needles) in May 2023 and loose garbage in January 2020, both of which were resolved. Historical records from 2000 indicate a period of safety compliance work, including the installation of handrails to meet code requirements. While most historical violations have been addressed, the building's maintenance history shows ongoing attention to exterior upkeep and compliance with safety standards during the early 2000s.

Risk rating

How 1142-1144 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.
