Initial analysis

The property at 304-306 Brazil Avenue is a two-unit, two-story multi-family residential building constructed in 1910, currently owned by Chen Yao Xuan. The building has undergone significant recent improvements, with major renovations completed in 2024 including kitchen and bathroom remodels (costing $35,000), electrical upgrades (costing $11,000), window replacements, and extensive plumbing work involving new sewer systems and water pipes. These improvements follow a history of maintenance issues and violations, most notably a serious incident in 2012 when the attic space was improperly converted into a dwelling unit, leading to multiple life safety concerns including lack of proper egress and heating systems. This unauthorized conversion was later addressed through proper permits that legalized the attic modifications and corrected various safety violations.

The building's maintenance history shows periodic issues with windows, weatherproofing, and various interior surfaces, many of which have been addressed through recent renovations. Three building complaints were filed in 2024 regarding construction noise, though these appear to have been resolved. The property has maintained a generally active permit record, with the recent completed permits indicating significant investment in building improvements. Historical permits show earlier repairs including plumbing upgrades in 1983 and a re-roofing project in 1998, though these were completed many years ago. The property has experienced recurring issues with exterior maintenance, as evidenced by multiple graffiti incidents (most recently in 2019), and sidewalk concerns, though these are primarily cosmetic in nature.

Risk rating

How 304-306 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.

Neighborhood percentile

Out of 337 buildings in this neighborhood, 195 are predicted to be safer.
