Initial analysis

The property at 3573-3575 18th Street, located in the Mission Dolores neighborhood, is a two-unit multi-family residential building constructed in 1909, featuring two stories and owned by Hong Van Nguyen & Cam Lu. The building's history shows several significant modifications and maintenance work, including a reroofing project completed in 1988, and efforts to address water damage in the basement in 1985 following code violations. Notably, there were two attempts in 1987 to revert the building from four apartments back to two flats, with one permit being cancelled and the other ultimately completed. More recently, in 2015, there were complaints regarding illegal construction without permits, and a cancelled electrical permit in 2016 for unit renovations including kitchen and bathroom remodeling and fixture replacements.

The property has experienced recurring maintenance and safety concerns in its vicinity, with multiple 311 calls reporting issues between 2019 and 2024, primarily involving graffiti on various surfaces including the building itself, street areas, and nearby mailboxes. There have been several reports of human or animal waste requiring clean-up services, particularly in 2019 and 2024. The most recent building-related service call was for graffiti on the residential building in March 2021, while external maintenance issues have persisted, including a blocked driveway incident in 2020 that resulted in a citation. The building's documented permit history shows regular maintenance activity, though some permits from 2001 for sidewalk work show as expired, and there appears to be no recent major structural modifications on record since the 2015 illegal construction complaint.

Risk rating

How 3573-3575 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.
