Rent & eviction protection

Is 771 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 1952

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.

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 two-unit residential building at 771 Wisconsin Street in Potrero Hill is a two-story flats and duplex structure built in 1952, currently owned by Carol A Sundell Separate Pr. The property has undergone several significant renovations, with the most recent being a complete re-roofing project in 2023 costing $10,700. A substantial renovation occurred in 2009, which included comprehensive updates to both units with work totaling over $141,500, encompassing bathroom remodels, kitchen renovations, electrical system upgrades (including new double meter service with 200-amp and 100-amp services), and plumbing improvements. During this period, there was one building complaint filed regarding unauthorized work hours and missing permits, though this was quickly addressed within a day. The building's maintenance history shows attention to safety concerns, including a stair repair project in 2010 addressing rot damage.

The property has experienced some recent infrastructure issues in the vicinity, with multiple reports of sidewalk defects in 2023, including one that was specifically noted as a "collapsed sidewalk" issue around a utility vault, though this was later resolved. A sewage backup incident was reported and resolved in late 2021, and there have been occasional parking-related issues near the property, though these do not directly impact the building itself. The most recent major systems upgrade was the roofing project in 2023, suggesting regular maintenance is being performed. The building's unit configuration and boundaries were clarified in 2009, establishing it as a legal two-unit property with upper and lower unit designations (771 and 771A).

Risk rating

How 771 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
61stpercentile

Out of 726 buildings in this neighborhood, 283 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
