Rent & eviction protection

Is 515-517 Natoma 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

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 three-unit residential building at 515-517 Natoma Street in San Francisco's South of Market neighborhood, constructed in 1910, has experienced several significant maintenance and safety issues over recent years, with particular emphasis on problems between 2019-2020. The property, currently owned by Cara Natoma LLC, has faced multiple building violations that remain active as of October 2023, including issues with stairs, siding, flooring, and paint that require attention to comply with local housing codes. The building has undergone various repairs in response to these violations, including a $5,000 project in August 2020 to address multiple compliance issues through repairs to stairs, siding, and exterior trim, as well as a $2,000 repair to basement ceiling drywall in March 2020 to meet fire safety requirements.

Heating issues have been a recurring problem, with three separate complaints in 2019-2020 regarding inadequate heat in occupied rooms, leading to violations of housing code requirements for maintaining minimum room temperatures. Three different heating-related complaints were filed in 2020 alone, with one specifically mentioning fire alarm activation and a blocked thermostat. The building's maintenance history shows attention to both safety and comfort issues, with a gas wall heater replacement completed in November 2019 and various repairs to stairs and interior surfaces documented through building permits. While some violations have been addressed and completed, others remain open as of the latest data, indicating ongoing maintenance challenges. The property has also undergone several routine health and safety inspections between 2004 and 2019, revealing ongoing attention to building conditions. Recent 311 calls from early 2025 primarily relate to street-level cleanliness and encampment issues in the immediate vicinity of the building, rather than directly involving the property itself.

Risk rating

How 515-517 Natoma 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
