Statewide backstop · AB 1482

Coverage unclear. AB 1482 turns on the certificate-of-occupancy date and property type — confirm the year the building was completed.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The property at 628-638 Brazil Avenue in the Excelsior neighborhood is a multi-family residential building consisting of two units, classified as Flats & Duplex and attributed to owner Guang Jun Zeng. The building's most significant recent structural improvement occurred in 2017, when the exterior received $18,500 worth of siding replacement with Hardie board on all visible sides, completing a notable upgrade to the building's facade. Previously, in 1998-1999, the property underwent initial construction as a three-story two-unit residential building valued at $340,000, followed by revisions for stucco exterior finishes and new fireplaces.

The building has experienced recurring issues with parking violations in the surrounding area, particularly concerning sidewalk obstructions, with seven documented incidents between 2018 and 2024, though most resulted in either officers being unable to locate the offending vehicles or the matter being addressed without citation. There was also one instance of a driveway blocking complaint in November 2024 that was deemed invalid due to incomplete reporting information. Additionally, there have been two incidents involving garbage and debris issues near the property, with the most recent occurring in September 2024. A noteworthy historical issue was documented regarding an illegal unit in the single-family house, which has since been abated. A traffic calming application was submitted in 2020 but was not accepted, with the program planning to email the application for the FY 21/22 period.

Risk rating

How 628-638 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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
89thpercentile

Out of 337 buildings in this neighborhood, 37 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
