Rent & eviction protection

Is 24-28 Langton 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 1911
2 or more units

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 1911
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 three-story, 6-unit multi-family residential building at 24-28 Langton Street, owned by the Patricia Kiely Trust, was constructed in 1911 and has undergone several significant modifications over its history. Most notably, the building completed a mandatory soft-story retrofit in 2016 (with a cost of $6,001) to improve seismic safety, meeting requirements under the San Francisco Building Code. The building's safety history includes a fire incident in 1984 that required repairs, with records from both April and August of that year showing clear-outs and fire damage repair work.

In September 2007, the building underwent a routine safety inspection that resulted in multiple violations related to fire safety and gas utility requirements, including the need to recharge fire extinguishers and provide gas shutoff tools. These violations were all resolved by September 27, 2007. The most recent permitting work was for a shear wall relocation in 2016, which was successfully completed. The property is currently listed as having completed its soft-story retrofit with a Certificate of Final Completion issued. Recent 311 calls from 2024 primarily relate to street conditions around the building, including reports of human waste, debris, and curb defects, as well as encampments in the vicinity, though these external issues don't directly indicate building safety concerns. An open case from September 2024 related to structural maintenance (fencing iron work) is currently pending resolution.

Risk rating

How 24-28 Langton 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
53rdpercentile
