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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
