Initial analysis

The 740 Leavenworth Street building is a 15-unit, 4-story multi-family residential apartment building constructed in 1924 and currently owned by Dyn Tr. The property has undergone several significant safety system upgrades in recent years, most notably a complete fire alarm system upgrade in February 2024 and modifications to the fire alarm system in June 2023 to meet current safety codes, including the installation of low-frequency sounders in sleeping areas. However, there are currently open violations related to sleeping area requirements as of December 2023, while a previous sprinkler system violation from October 2023 has been abated.

The building's maintenance history shows regular attention to essential systems, with a new steam heating boiler and domestic hot water equipment installed in 2014, following earlier improvements including a rooftop repair completed in 1988 and a parapet safety program completion in 1987. The property has undergone routine housing inspections over the years (most recent in 2017), with several fire safety issues identified and subsequently addressed between 2010 and 2016, including fire escape ladder repairs, alarm panel certification, and smoke detector installations. While there have been multiple fire and building violations in the past, most have been promptly addressed, with the exception of the recent sleeping area requirement violation. The property has experienced some ongoing maintenance issues, as evidenced by various 311 calls for street cleaning and debris removal in the vicinity, most recently in October 2024, though these are not directly related to building maintenance.

Risk rating

How 740 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
57th percentile

Out of 448 buildings in this neighborhood, 193 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.

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 12.0%
Moderate concern 51.9%
Severe concern 36.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
