Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 2003
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
May be covered by AB 1482. The building is old enough for the statewide rent cap (5% + regional CPI, capped at 10% per year) and just-cause protection after 12 months of tenancy.

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 475-477 30th Avenue property is a four-story, two-unit multi-family residential building constructed in 2003, owned by Angela N. Lam. The building was completed with modern safety features including a comprehensive fire sprinkler system installed throughout the structure at a cost of $12,000 in 2003, with subsequent backflow prevention work completed in 2017. The original construction phase included the installation of essential systems such as new furnaces, water heaters, and electrical infrastructure including a 250-amp service panel. Several building improvements have been attempted over the years, including a cancelled 2019 permit for window replacement and previously expired permits for various interior modifications in 2002-2003, such as partitioning a playroom and exercise room.

The property has experienced periodic maintenance and environmental issues typical of urban settings, including multiple noise complaints related to amplified sound in 2020, though these were summarized as informational reports. Recent municipal service interactions include closed cases for garbage-related issues in 2024, with previous incidents of litter and street cleaning matters recorded in 2009-2010. The building's facade and window maintenance appears to have been addressed through planning records, with documentation showing repairs to leaks, window replacement, and siding work completed in accordance with 2019 specifications. While there have been various service calls to the address, they primarily reflect routine urban maintenance concerns rather than building-specific issues, and no significant safety or regulatory violations have been recorded.

Risk rating

How 475-477 30Th 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
98thpercentile

Out of 2250 buildings in this neighborhood, 45 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
