Initial analysis

The 15-unit, 3-story apartment building at 1429 Leavenworth Street in Nob Hill, owned by the Chow Family Trust, has undergone several significant improvements and faced numerous maintenance challenges since its construction in 1913. The building completed its mandatory soft-story retrofit in 2016 (with a CFC issued) and received a new roof in 2017 at a cost of $27,950. Most recently, in October 2024, the building is scheduled for a complete replacement of all 15 unit meters with a 200-amp main connection due to insurance requirements. The building has experienced recurring heating system issues, with complaints about no heat in 2022 and 2023, and in December 2024, there are active complaints regarding peeling exterior paint and accessibility concerns with the ground floor entrance.

The property has a documented history of maintenance issues and violations, particularly relating to fire safety systems. Notable past fire safety violations include problems with alarm systems (most recently in September 2023), fire extinguishers (2021), and various security requirements. The building underwent significant plumbing work in 2022, involving repairs in units 102 and 203 that resulted in temporary loss of bathroom facilities for unit 203 and affected multiple floors. Additional maintenance concerns have included elevator outages, door access issues, and water leaks, with various complaints filed between 2022 and 2024. The property has maintained basic compliance with major safety requirements, completing seismic upgrades and various required repairs, though some historical violations remained active until addressed by June 2009.

Risk rating

How 1429 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, 1080 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 8.8%
Moderate concern 57.3%
Severe concern 33.8%
