Rent & eviction protection

Is 52-56 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 1915

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 1915
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 property at 52-56 Langton Street is a three-story multi-family residential building located in the South of Market neighborhood, constructed in 1915 and containing three units. The building's maintenance history shows several significant repairs and improvements over the decades, including a sewer lateral replacement in 2020, water heater replacement in 2011, re-roofing in 2001, and structural repairs to stairs and foundations in 1995. A notable historical change occurred in 1985 when an illegal basement unit was removed and converted to laundry facilities, and there were various applications related to unit modifications in the 1980s.

Recent concerns have emerged regarding fire safety compliance, with violations issued in 2024 for sleeping area requirements and standpipe system issues, though the standpipe violation was subsequently abated. The building previously faced multiple fire safety violations in 2007, including problems with fire extinguishers and the central alarm system, all of which were resolved by May 2008. The property has undergone routine inspections by Housing Inspection Services in 1999 and 2007, with all issues addressed and closed. The surrounding area has experienced some ongoing maintenance challenges, as evidenced by multiple recent 311 calls between 2024-2025 regarding garbage, debris, and parking violations, though these are primarily external to the building itself.

Risk rating

How 52-56 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
75thpercentile

Out of 430 buildings in this neighborhood, 108 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Building size

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
