Initial analysis

The 6-unit multi-family residential building at 3650 18th Street in Mission Dolores, owned by Walter & Diana Wong Family, was constructed in 2003 following the demolition of a two-story office building that occurred in 2001-2002. The four-story building's construction included essential safety systems, with fire system installation and life safety tests completed between 2002 and 2003. The building has undergone several inspections and compliance checks over the years, with the most recent inspections in 2022-2023 noting no violations, though compliance affidavits were required. Notable violations in 2005 and 2011 related to fire safety equipment, including fire extinguishers and alarm systems, were promptly addressed and abated.

The property has experienced periodic maintenance and compliance issues, particularly regarding fire safety systems and interior surfaces. In 2011, there were multiple violations concerning water damage, damaged ceilings, and egress obstructions, all of which were resolved. A 2003 complaint about potential facade issues was investigated but ultimately resolved. The building's permit history shows standard development activities, including street space permits in 2002 and 2011. Recent 311 calls from 2023-2024 primarily relate to street-level issues such as parking violations and sanitation concerns, which are more relevant to the immediate neighborhood than the building itself. Two withdrawn planning proposals related to height modifications were submitted in the past, but they are no longer active.

Risk rating

How 3650 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 799 buildings in this neighborhood, 623 are predicted to be safer.
