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 1987
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 1639 10th Avenue in San Francisco's Inner Sunset neighborhood has undergone several significant events since its construction in 1987, following the demolition of a prior structure in July 1986. The three-story flats and duplex building has maintained a relatively low incidence of serious complaints or incidents over the past several years. The most recent issues have primarily involved minor parking-related concerns, with multiple reports of vehicles blocking driveways or parking on sidewalks between 2019 and 2020, though in each case, responding officers were unable to locate the offending vehicles. A street cleaning issue involving loose garbage was reported and resolved in September 2021, representing the most recent documented resident-initiated complaint. The building appears to have maintained its structure and systems without major reported incidents, and there are no recorded safety violations or significant maintenance issues in the available data.

Risk rating

How 1639 10Th 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
81stpercentile

Out of 1493 buildings in this neighborhood, 284 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
