Rent & eviction protection

Is 2 Sumner 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.

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

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-story, multi-family residential building at 2 Sumner Street in San Francisco's South of Market neighborhood was built in 1916 and currently contains two units, owned by Michael Andrew Wolf. The property has undergone several significant modifications and repairs over the years, most notably a $20,000 deck repair project completed in 2021, and more substantial renovations including bathroom remodeling, laundry installation, and water heater replacement in 2021. Two major development proposals were previously considered: in 2017, there was a cancelled plan to convert the ground floor from commercial to residential use, add a third floor, and include roof decks at all levels, and in 2001, a cancelled proposal for dwelling renovation above a garage was submitted.

The property has experienced recurring issues with street and sidewalk conditions in the immediate vicinity, particularly between 2023 and 2024, with multiple reports of garbage, debris, and medical waste (needles) documented by various city agencies. There were also several encampment-related incidents reported between May 2023 and February 2024, though most were resolved quickly, with police unable to locate individuals in one case, and areas being cleared in others. The building's safety systems have been addressed in the past, with fire-related inspections showing resolution of an unspecified issue in 2010 and correction of alarm system problems in 2007, though it's worth noting that both incidents are now over a decade old. Planning records indicate various development proposals for the site, including a requested variance for rear yard requirements and mixed-use unit considerations, though none of these proposals ultimately proceeded as originally planned.

Risk rating

How 2 Sumner 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
92ndpercentile

Out of 430 buildings in this neighborhood, 34 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
