Initial analysis

The 2-story multi-family residential building at 3360 18th Street in the Inner Mission, owned by Rodemiro & Isabel Arguello, is a 4-unit apartment structure constructed in 1961. The building has undergone several window upgrades over the years, with the most recent being a 2013 installation of three vinyl windows in Unit #4, featuring energy-efficient double-pane glass. A plumbing issue was addressed in 2015 involving the installation of a three-foot secondary line.

The property has experienced periodic routine safety inspections, with significant safety-related citations occurring in 2007 and 2010. These citations, all of which were ultimately resolved by November 2010, included violations related to the smoke detection system, central alarm system requirements, and self-closing devices at exterior doors. More recently, the building has faced recurring sewer issues, with documented backups in late 2023 (January, December, and September), and several graffiti incidents on the building between 2023-2024. A general hazardous materials complaint was filed in May 2023 but was determined to have no merit.

Risk rating

How 3360 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.
