Initial analysis

The property at 1404-1406 Leavenworth Street is a 3-story, 2-unit multi-family residential building located in San Francisco's Nob Hill neighborhood, currently owned by Matthew and Jessica Diamond. Built in 1908 and classified as a Flats & Duplex structure, the building has undergone several maintenance and improvement attempts over the years. Most notably, in 2019, a significant proposal was filed to remodel and add to the existing structure, transforming it into a 5-story building with 3 units and a garage/lobby area, though this project is currently listed as "On Hold" in the planning records. Previous building maintenance included repairs for dryrot damage in 2011 and sidewalk repairs in 2001.

Recent activity at the property (2023-2024) has primarily involved external issues, particularly regarding street maintenance and parking concerns. There have been multiple reports of garbage and debris on the street, illegal parking, and abandoned vehicles in the vicinity, though these are external neighborhood issues rather than building-specific concerns. The building has experienced three fire safety system activations in recent years, including two false alarms and one carbon monoxide detector activation, none of which resulted in injuries or actual fire damage. The property's planning history indicates significant ambition to increase housing density on the site, with proposals to exceed current zoning allowances, though the specific permit status suggests this has not progressed to construction phase. The proposed improvements would update the building's facade, improve entry lobby features, and include new landscaping elements like planting strips and a front street tree.

Risk rating

How 1404-1406 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

Out of 1125 buildings in this neighborhood, 281 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

12-Month severity forecast
No violation 90.6%
Moderate concern 7.6%
Severe concern 1.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
