Initial analysis

The two-unit residential building at 3577 18th Street in Mission Dolores, owned by the William Gong Lum Bypass Trust, has undergone several notable improvements and faced recurring maintenance challenges since its construction in 1909. Most recently, in August 2024, there was a completed $15,000 reroofing project, representing significant infrastructure maintenance. The building's maintenance history includes an aluminum window installation in 1995, though there were also two street space permits issued in 2020.

The property has experienced persistent issues with graffiti over the past two years, particularly from 2022 through 2023, with multiple incidents occurring between May and September 2023 being documented, though several cases were administratively closed due to technical issues with service delivery. There were two instances of graffiti in 2022 that were successfully resolved by appropriate authorities, including one involving defacement of an AT&T box and one on a power line pole that was addressed by the SES Graffiti Crew. In addition to these challenges, there was a general cleaning issue related to loose garbage reported and resolved in September 2023. The building's recent developments and historical maintenance record suggest ongoing attention to infrastructure improvements, particularly with the recent roofing project, while also highlighting the neighborhood's external maintenance challenges that have persisted over several years.

Risk rating

How 3577 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.
