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 1986
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 two-unit residential building at 571 37th Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1986, currently owned by Kee Lum & Lily Y Won Family. The building's documented history shows relatively few significant events, with most activities occurring during the 1980s and mid-2000s. The property was previously demolished in late 1984 (with two demolition permits issued on November 15 and 16), before being reconstructed into its current form. In 2000, there was an expired permit for sidewalk repair work, though there are no records of subsequent issues with the sidewalk.

More recently, there was a concerning complaint filed in October 2022 regarding a bad smell coming from the downstairs plumbing, which was directed to Housing Inspection Services, though the status is marked as "Not Active." The building has had several 311 calls related to the property, mostly concerning street and sidewalk issues. These include a parking enforcement call for a driveway blocking incident in January 2025 (resulting in an officer response but unable to locate the vehicle), a sidewalk parking complaint in December 2019 (which could not be validated by responding officers), and an abandoned vehicle report in October 2015 (for a black Toyota Corolla that was gone upon arrival of authorities). There were two incidents in April 2015 involving public works matters: one related to a missing sewer vent cover at 567 37th Avenue, and another concerning loose garbage that was subsequently resolved.

Risk rating

How 571 37Th 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
36thpercentile

Out of 1040 buildings in this neighborhood, 666 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
