Rent & eviction protection

Is 273-275 San Carlos 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 1910
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1910
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-unit multi-family residential building at 273-275 San Carlos Street in the Inner Mission, built in 1910, has experienced several significant maintenance and compliance issues over the past several years. Most notably, in 2018-2019, there were multiple health and safety violations including mold/mildew on ceilings and walls, damaged walls and ceilings, broken windows, plumbing issues, and fire safety concerns, all of which were addressed by October 2018 through necessary repairs and upgrades. The property underwent several window replacements between 2005-2019, including a 2019 project to repair a single window facing the rear yard at a cost of $1,108. Roof maintenance has also been a recurring issue, with repairs needed in 2019 for a leak above a bay window, which was initially reported as causing water damage and potential mold growth. The building has been equipped with solar panels since 2005, and electrical upgrades have included the installation of additional plugs in 2003. A notable ongoing concern involves allegations of an unauthorized dwelling unit on the property, with investigations and enforcement actions initiated between 2016-2020, though this matter appears to currently be on hold with a Notice of Proposed Foreclosure issued in late 2020.

Recent activity at the property has primarily consisted of maintenance and cleaning issues, as evidenced by numerous 311 calls in late 2024 and early 2025 regarding garbage, debris, and water leak issues, though these are typically street-level concerns not directly related to building conditions. The building's permit history shows regular maintenance and improvement work, including window replacements, solar panel installations, and various repairs to maintain compliance with safety regulations. While the building experienced significant compliance issues in 2018-2019, these were addressed through appropriate permits and inspections, though the ongoing unauthorized unit investigation suggests some historical compliance issues may persist.

Risk rating

How 273-275 San Carlos 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
