Rent & eviction protection

Is 73-75 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 1906

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 1906
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 multi-family residential building at 73-75 Langton Street, currently owned by Michelle Lewis, was constructed in 1906 and contains three units plus ground-floor commercial space. The property has undergone several significant improvements, most notably a comprehensive $37,500 renovation in 2019 that included kitchen and bathroom updates, electrical upgrades, and new plumbing fixtures, along with the removal of knob and tube wiring and installation of modern electrical systems throughout the unit. The building has a documented history of fire safety concerns, with recurring issues related to alarm systems, sprinkler/standpipe systems, and blocked exits between 2020 and 2024, though most have been resolved. Recent maintenance records show attention to building systems, including air conditioning installation in 2008 and various electrical upgrades.

The property has faced challenges with exterior maintenance and environmental conditions in recent months, as evidenced by multiple 311 calls in late 2024 and early 2025 reporting graffiti, garbage, debris, and sewage issues near or around the building. There was a notable building complaint in 2006 regarding a possible illegal unit and lack of fire escape exit, though this was abated later that year. The ground-floor commercial space has undergone various modifications over the years, including bathroom and shower installations in 2006 and partition work in 2000. The building's fire safety systems have required regular attention, with the most recent fire complaint in early 2024 related to alarm systems, which was marked as "Condition Corrected" upon follow-up inspection. While many historical permits show proper maintenance and upgrades, including a reroofing project in 1989, the property has experienced occasional setbacks with compliance and safety systems that warrant monitoring.

Risk rating

How 73-75 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
54thpercentile

Out of 430 buildings in this neighborhood, 198 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
