Initial analysis

The three-story multi-family residential building at 3220-3222 18th Street in the Inner Mission, owned by Tran Fmly Tr, was constructed in 1876 and contains three units. The property has undergone several significant improvements in recent years, with substantial renovations completed in 2015-2016 including comprehensive remodels of bathrooms and kitchens in multiple units, with associated electrical and plumbing upgrades totaling approximately $75,000. The building's maintenance history shows attention to basic infrastructure, though some permits from previous decades (1995 roof work, 1985 foundation repairs) are listed as expired or cancelled.

The property has been subject to regular safety inspections by Housing Inspection Services, with routine inspections occurring in 2008 and 2015, and a notable complaint in 2003 concerning potentially unauthorized ground floor apartment construction and unstable block foundations, though this was abated within weeks. More recent issues have primarily involved external matters, with multiple 311 calls in 2023-2024 related to street cleaning and encampments in the vicinity, rather than building-specific concerns. Three fire complaints were filed between 2015-2016, including one hoarding issue and two unspecified complaints, though all were resolved with conditions corrected. The most recent building-related activity involves a construction noise complaint in October 2023 that was investigated but no violation was found.

Risk rating

How 3220-3222 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
