Initial analysis

The property at 4517 18th Street is a two-unit, two-story multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood. Built in 1905 and owned by the Leo Petroni 2018 Revocable Trust, this flats and duplex-style building has undergone several significant improvements over the past two decades. In 2012, the building underwent a substantial interior renovation costing approximately $50,000, which included kitchen and bathroom remodels in both units, the addition of a half bathroom on the second floor, and associated plumbing and electrical work - all of which were completed successfully. The building's exterior received attention in September 2010 with the installation of scaffolding for facade siding repairs.

In 2016, there was an attempt to construct a two-bedroom, one-bath ADU (accessory dwelling unit) in the bottom level, but this permit application was ultimately withdrawn. The property has experienced recurring issues with sidewalk maintenance, with multiple reports of defects and lifted sections between 2019 and 2022, though most of these cases have been resolved. The building's immediate vicinity has been subject to various municipal service calls primarily related to street and sidewalk maintenance, including reports of garbage, abandoned vehicles, and illegal parking, though these issues are generally not directly related to the building's condition or safety. The most recent records indicate no active building violations or permits as of the current date in October 2023.

Risk rating

How 4517 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

Out of 1278 buildings in this neighborhood, 486 are predicted to be safer.
