The property at 1536-1538 18th Street in Potrero Hill is a two-story, two-unit multi-family residential building constructed in 1908, currently owned by the McCarthy-Economy Revocable Trust. The building has undergone several significant renovations and maintenance work over the past three decades, with the most recent major improvement being the installation of a three-zone air conditioning system with heat pump and new air handlers in December 2024, representing a modern HVAC upgrade. Historical records indicate multiple roofing and window-related projects in the early 1990s, including two separate roofing permits in 1993, window replacement work in 1994, and fence repairs in 2000. The building experienced some structural and maintenance work in 1993, including drywall patching, wood floor repairs, window work, and beam replacement.

Recent issues affecting the property include a sidewalk defect reported in September 2022 involving lifted sidewalk conditions, which was resolved by the Department of Public Works. There was also a parking violation incident involving a Tesla Model 3 on the sidewalk in August 2022, though responding officers were unable to locate the vehicle. Earlier service calls include a 2014 duplicate service request to Recology for abandoned items. The property's documented maintenance history shows regular upkeep over the years, with the most recent upgrade significantly improving the building's climate control system.

Risk rating

How 1536-1538 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.
