Initial analysis

The two-unit residential building at 645 Brazil Avenue, owned by Sonia Escolero, is a 2-story flats and duplex structure built in 1908 in the Excelsior neighborhood. The building's maintenance history includes two significant plumbing upgrades: a complete bathroom renovation in 1998 involving fixture replacements and plaster repairs, and a water supply conversion to copper pipes in 1984. However, there is an unresolved complaint filed in February 2015 regarding unauthorized rental of rooms in the garage and rear yard, which were constructed without permits in October 2014.

The property has experienced several infrastructure and maintenance issues in recent years, with the most recent incident being a burnt-out streetlight reported in August 2024. Other notable incidents include a sewage backup issue in March 2022 that required field work by the PUC Sewer Operations, and multiple tree-related service requests in early 2019. The building's vicinity has faced various urban maintenance challenges that have been addressed by city services, including graffiti removal, sidewalk repairs, and street cleaning. While most of these external issues have been resolved, they suggest ongoing urban maintenance needs in the area surrounding the property.

Risk rating

How 645 Brazil Ave'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.
