Initial analysis

The two-unit residential building at 3985-3987 Mission Street in Bernal Heights, owned by Ettore & Antonietta P Timpa, has experienced several notable events since its construction in 1957. Most significantly, in September 2007, the property faced a series of substantial habitability issues that resulted in multiple building violations, including problems with mold and mildew throughout various rooms, inadequate heating system performance, plumbing system deficiencies including repairs needed for tub/shower and sink fixtures, wall damage, and a broken window pane. These violations were all officially abated by January 14, 2008. The building underwent electrical system improvements in 2003 with an underground service conversion to 125-amp service with two meters, which was successfully completed.

More recent incidents include plumbing challenges in 2017 with reports of flooding and sewage backup issues, as well as exterior maintenance concerns such as graffiti removal (2018-2019) and a sidewalk defect report (2015) that noted collapsed sidewalk squares. A minor incident involving an explosion without fire was recorded, though no civilian injuries were reported. The only documented parking-related issue at the property occurred in 2020, resulting in a citation. While the building has had various maintenance and safety concerns over the years, most historical violations have been resolved through proper remediation, including the significant 2007 housing violations which were addressed through city enforcement and corrected by the beginning of 2008. The permits and work completed suggest ongoing attention to infrastructure maintenance, including the cancelled foundation underpinning permit from 1987, though it's unclear why this permit was not pursued to completion.

Risk rating

How 3985-3987 Mission 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.
