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 1988
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 Johnson Family Trust owns this two-unit, two-story multi-family residential building located at 527-535 Wisconsin Street in Potrero Hill, which was originally constructed in 1988. The property has undergone several significant improvements over the years, with the most recent being a completed reroofing project in January 2024 costing $20,000. In 2018, major infrastructure upgrades were completed including both sewer lateral replacement and bathroom installation in the family room, demonstrating ongoing maintenance of essential systems. Earlier improvements include energy-efficient upgrades such as window sash replacements in 2014 (eight wood-clad windows with U-factor .40) and the installation of a 3.375 kW solar PV system in 2009. The building's maintenance history shows regular upkeep, including water heater replacement in 2014 and various window-related work in the early 1990s.

The property has had some planning considerations, most notably a proposed but disapproved exception to rear yard requirements for a two-story deck and stair structure. This proposal, which went through several reviews in the early 1990s, was ultimately not permitted. The building's history indicates responsible maintenance and upgrades by the ownership, with no significant safety or resident experience concerns documented in the available records. The most recent building improvements, including the 2024 reroofing project, suggest ongoing commitment to maintaining the property's infrastructure and systems.

Risk rating

How 527-535 Wisconsin St'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
96thpercentile

Out of 726 buildings in this neighborhood, 29 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
