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 1982
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 173 12th Avenue property is a three-story, two-unit multi-family residential building located in the Lake-Presidio neighborhood, built in 1982 and currently owned by Wong Family Trust. The building has a relatively quiet record with only three significant permit applications and three 311 calls on file since its construction. All three building permits from the early 1980s (numbers 8104732, 8205775, and 8302640) were successfully completed, with the last one in March 1983 specifically noting the addition of property line windows among other modifications.

The most recent incident associated with the property occurred in July 2024, involving parking enforcement due to sidewalk obstruction, which was resolved with the issuance of a citation. A defaced sign was reported and repaired in August 2021, and there was one invalid complaint regarding driveway blocking in January 2019, which couldn't be processed due to incomplete reporting information. While the number of incidents is relatively low for a multi-unit residential building, the most significant recent issue pertains to the parking enforcement matter, though it appears to be more related to street parking than building-related amenities or services.

Risk rating

How 173 12Th 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
52ndpercentile

Out of 660 buildings in this neighborhood, 317 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
