Rent & eviction protection

Is 1137-1139 Kansas 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 1907

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1907
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-family residential building at 1137-1139 Kansas Street in Potrero Hill is a 2-story flats/duplex structure built in 1907, currently owned by Spencer & Fallon Ke Mulcahy. The property has experienced several significant maintenance and infrastructure issues in recent years, with one of the most concerning being multiple reports of sewage leaks in 2024-2025, affecting the sidewalk and retaining wall areas. There have also been ongoing issues with plumbing and sewer systems, including a November 2024 sewer odor incident and a December 2024 plumbing problem. The building's maintenance history shows interest in improvements, with records indicating window and door replacements in 2010, and a substantial rear deck renovation undertaken in 2008 costing $10,000. There have been past concerns about unauthorized unit use and short-term rentals, with complaints filed in 2021 and 2008, though these were subsequently addressed. Recent external issues include multiple sidewalk parking violations, an unresolved sidewalk defect due to tree roots, and a temporary graffiti incident from August 2024. The property's planning records confirm the rear deck addition was properly permitted and approved, indicating some level of compliance with building regulations.

Risk rating

How 1137-1139 Kansas 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
