Initial analysis

The three-story, 6-unit multi-family residential building at 1430 Leavenworth St in San Francisco's Nob Hill neighborhood was built in 1909 and has undergone significant structural and safety improvements over the past several years. Most notably, the building completed its mandatory Soft Story retrofit program in 2023 (Tier 4), achieving compliance with San Francisco Building Code requirements. Between 2019-2022, substantial enhancements included the conversion of ground-floor storage spaces into three new residential units (totaling 9 units), installation of a new 400-amp electrical service panel, comprehensive fire safety upgrades including a new fire alarm system with monitoring capabilities, and the addition of 27 sprinklers throughout the ground floor. The building's safety infrastructure has been systematically improved, with recent work including the installation of low-frequency sounders in sleeping areas and compliance with updated fire code requirements.

Historical records show that the building faced several safety-related issues in the early 2000s, including concerns about fire escapes, stairway conditions, and fire extinguishers, though these violations were promptly addressed and abated. More recent routine inspections in 2016, 2018, and 2022 have focused primarily on seismic retrofitting requirements. The property has maintained active compliance with all major building addresses since 2022, completing significant infrastructure improvements including an upgraded fire alarm system, new residential units, and electrical service modernization. The improvements reflect ongoing investment in building safety and habitability, with particular attention paid to seismic preparedness, fire safety, and modernization of building systems.

Risk rating

How 1430 Leavenworth 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.

Neighborhood percentile
