Potrero Hill, SF 94107 4162051 2 units · 2 fl · 1943

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.

Rent & eviction protection

Is 927-929 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 1943

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 927-929 Wisconsin Street in Potrero Hill is a 2-story flats and duplex structure built in 1943, currently owned by John E. Mason. The building's maintenance history shows some significant work completed in 2003, when repairs were made to address stucco and plywood sheathing issues, though records indicate these permits have since expired. A more sustainable upgrade was completed in 1985 with the installation of a solar pre-heat system for domestic hot water, demonstrating early investment in energy efficiency.

Recent street conditions around the property have generated multiple reports through the 311 system, with the most recent calls in 2025 and 2024 relating to litter receptacle maintenance and general street cleaning. The area has experienced recurring issues with loose garbage on sidewalks, as evidenced by multiple reports between 2018-2024. There have been several incidents involving abandoned vehicles on the street, with the most recent in January 2024, and two significant public safety concerns in 2018-2019 involving human or animal waste on public property. A notable safety incident occurred in October 2017 involving a pavement defect and a potentially hazardous down wire situation that required PG&E intervention. While these exterior issues don't directly impact building habitability, they do reflect on the surrounding neighborhood conditions.

Risk rating

How 927-929 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
24thpercentile

Out of 726 buildings in this neighborhood, 552 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
