Rent & eviction protection

Is 1040 Wisconsin St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built before 1979
Built 1900
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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.

Built 1900
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

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 property at 1040 Wisconsin Street in Potrero Hill is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by Morris Dianne Rev Liv Trust. The building has experienced several significant infrastructure issues over the years, most notably between late 2006 and early 2007 when there were serious sewage leakage problems affecting both the property's sewer line and neighboring properties, requiring multiple notices of violation before being abated in February 2007. More recently, in 2017, there was an active complaint regarding insects/rodents, damaged walls, and accessibility issues related to property overgrowth and debris, as well as reported issues with path of travel access.

The building has undergone various safety and infrastructure improvements, including the installation of a fire alarm system in 1996 (now expired), a small wall heater installation in 2021, an electrical service correction in 2008, and attempted upgrades to the electrical panel in 2007 (though this permit was cancelled). Two fire alarm system complaints were recorded in 2009 and 2010, but were promptly corrected. More recently, there have been multiple parking-related complaints in the vicinity, including several cases of blocked driveways and double parking between 2023 and 2024, though these are external to the building itself. The property has also required attention to hazardous materials on the street/sidewalk area, with two incidents reported in 2023 involving glass and liquid substances, both of which remain open as of 2024.

Risk rating

How 1040 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
4thpercentile

Out of 726 buildings in this neighborhood, 697 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
