Rent & eviction protection

Is 551 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 1913

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 1913
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 551 Wisconsin St in Potrero Hill, owned by Christopher & Loura J Sabre, has a construction history dating back to 1913 as a two-story flats and duplex structure. The building has undergone several significant maintenance events, most notably a complete re-roofing project costing $12,880 in 2015. The property experienced a substantial cluster of building violations in early 2015, with the Department of Building Inspection (DBI) issuing multiple notices on February 23, 2015, related to mold and mildew on various surfaces, damaged flooring, plumbing issues including a leaking toilet, security concerns regarding door locks, and general nuisance conditions - all of which were officially abated by May 28, 2015.

Additional concerns in 2015 included reports of bad electrical wiring in a bedroom (April 2015), and a complaint about a rear window and enclosed porch in 1998 suggesting possible unauthorized modifications. More recent activity at the address includes multiple 311 calls between September and November 2024 regarding building inspections and construction noise, though these appear to have been transferred for follow-up through proper channels. The property has two recorded fire incidents, both relatively minor - a system malfunction and a smoke removal situation, neither resulting in civilian injuries. External infrastructure issues have been noted, including a sidewalk defect reported in January 2023, which remains open as of the latest data.

Risk rating

How 551 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
68thpercentile

Out of 726 buildings in this neighborhood, 232 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

What's driving this score
