Initial analysis

The 7-unit apartment building at 1811 Leavenworth Street in Russian Hill, owned by Alfred Gee Bypass Trust, is a 4-story structure built in 1916 that has undergone significant modernization and safety improvements over the past several years. Most notably, the building completed a mandatory soft-story seismic retrofit in 2017 at a cost of $99,000, achieving Tier 3 status with Certificate of Final Completion issued. Between 2021 and 2022, substantial renovations were carried out in multiple units (2, 4, 5, 6, and 7), including converting dining rooms to studies/bedrooms, kitchen and bathroom rehabilitations, adding second bathrooms, and installing washer/dryer facilities, with each unit renovation costing approximately $30,000 to $50,000. The building's fire safety systems were also upgraded in 2021-2022, including a new fire alarm system installation to comply with current codes and the replacement of eight electrical sub-panels.

The property has experienced recurring boiler-related issues, with the most recent complaint in December 2024 regarding permit renewal that was subsequently resolved in January 2025. Historical violations from 2001 and 2008 pertaining to fire safety equipment, lead paint concerns, and security features were all addressed and abated. Plumbing improvements include the installation of backflow devices for the steam boiler system, with the most recent installation completed in April 2022. Recent maintenance and inspection history suggests active management and prompt response to building systems' needs, though the boiler permit renewal requirements indicate periodic administrative oversights. The building successfully completed all required safety upgrades, including the soft-story retrofit, and has maintained active permits for its essential systems, including plumbing and electrical infrastructure.

Risk rating

How 1811 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

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 size

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

Number of units

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 16.8%
Moderate concern 72.8%
Severe concern 10.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
