Potrero Hill, SF 94107 4161004 3 units · 3 fl · 1980

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

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 1980
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 three-unit, three-story multi-family residential building at 856-860 Wisconsin Street in Potrero Hill, owned by Brass Tina An, has undergone several significant maintenance and safety-related events since its construction in 1980. Most recently, in October 2018, substantial repairs were completed to address water damage, including the replacement of windows, doors, and siding at a cost of $40,000. Previous maintenance work includes plumbing repairs in 2003, which involved balcony repairs and responses to various violations including issues with electrical outlets, fire safety equipment, and plumbing systems, all of which were abated by September 2003. The building received multi-unit inspection follow-ups in 2008 and 2010, with identified safety concerns such as the need for updated fire extinguishers and security improvements being addressed.

The property has experienced some recurring issues with its infrastructure, as evidenced by multiple 311 calls in 2023-2024 regarding street cleaning and noise concerns, though these appear to be more related to the surrounding area than the building itself. Historical improvements include reroofing work completed in 1989 and two gas leak tests in 2010, both of which were successfully completed. Planning records show attempts to modify the front setback and rear yard length, with the former being disapproved. The most pressing recent building-related issues have been primarily external, involving street cleaning and parking concerns, with one open noise complaint from November 2024 that may not directly relate to building conditions. All historical building violations have been resolved, and there are no active building code violations on record.

Risk rating

How 856-860 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
9thpercentile

Out of 726 buildings in this neighborhood, 661 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
