Initial analysis

The property at 4522-4524 18th Street is a two-unit, two-story multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood, owned by Michael & Lynn Winslow Revo and constructed in 1910. The building has undergone several significant maintenance interventions over its history, particularly concerning the roof, with three documented roofing projects (two completed in 1993 and 1999, and one that expired in 1999). Major plumbing improvements include a complete water heater replacement in 2010. Two concerning housing complaints were filed in 1999, documenting multiple safety issues including broken windows, exposed wiring, damaged stairwell, interior walls, and bathroom mildew, though these cases were marked as not active.

More recent records from 2020 to 2024 show the building has faced various external infrastructure challenges, including an open sidewalk defect case (collapsed sidewalk) and tree root damage (lifting sidewalk) reported in late 2021. The property has experienced recurring issues with illegal parking and driveway blockages, particularly between 2021 and 2024, with multiple parking enforcement cases documented. Other external matters have included a resolved encampment situation in August 2022 and a general cleaning issue involving loose garbage in June 2020. While the building's historical maintenance records indicate attention to basic infrastructure (roofing and plumbing), the property has faced persistent neighborhood-related challenges in recent years, particularly regarding parking enforcement and sidewalk maintenance.

Risk rating

How 4522-4524 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.
