Rent & eviction protection

Is 152-156 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 1908

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.

Built 1908
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, six-unit multi-family residential building at 152-156 Langton Street, constructed in 1908 in San Francisco's South of Market neighborhood, has experienced several significant events over its history, with the most serious occurring in 2017. A fire incident in March 2017 (documented in multiple complaints) caused damage to ground floor unit 152A, leading to subsequent repair work that included replacement of windows, a water heater, bathroom fixtures, and other materials. This incident triggered multiple violations, including unpermitted window installations and fire safety concerns, though these violations were eventually abated by March 2024. The building has undergone several maintenance improvements, including a complete reroofing in 2015 (costing $9,000) and various unit-specific upgrades such as window replacements and bathroom fixtures. More recently, the property has faced ongoing issues with exterior maintenance, as evidenced by multiple 311 calls throughout 2023-2024 regarding garbage, debris, and cleanliness issues on the property's exterior, though these are not directly related to building safety or habitability. The most recent building-related activity on record is a water heater replacement and bathroom fixture upgrades completed in 2018. While the building has a history of various maintenance and compliance issues, particularly related to the 2017 fire incident, there are no active violations or pending repairs on record as of October 2023, and the property has since undergone multiple necessary improvements to address past deficiencies.

Risk rating

How 152-156 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
78thpercentile

Out of 430 buildings in this neighborhood, 95 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.
