Initial analysis

The two-unit residential building at 1034-1036 Natoma Street in San Francisco's South of Market neighborhood is a two-story flats and duplex structure built in 1907, currently owned by the Rosenthal & Anderson Living Trust. The building has undergone several significant structural improvements, including a complete reroofing in 1995 and a substantial foundation reinforcement project in 2005 that installed seven underpinning piers at the east wall. More recent events include a concerning series of complaints in 2020 related to demolition work during shelter-in-place orders, though no active status remains on that complaint. Between October 2024 and January 2025, there has been a notable pattern of sidewalk and street cleanliness issues in the immediate vicinity, with multiple reports of garbage, debris, and human waste requiring municipal attention. The building has also experienced two fire-related incidents, with a smoke scare reported and a fire alarm system issue in 2022 that was subsequently corrected, while a combustible materials complaint from 2020 was deemed to have no merit. A planning record indicates a proposal (now closed) for a larger development project to replace buildings at this and neighboring addresses with 24 condominiums, though this appears to have been informational only with no active status.

Risk rating

How 1034-1036 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.
