Initial analysis

1155 Leavenworth Street is a 21-unit residential building located in Nob Hill, constructed in 1911 and classified as a TIC building with 15+ units. The property has undergone several significant infrastructure improvements in recent years, most notably the recent installation of a new fire alarm system in April 2024 (with related electrical work completed in June 2024) costing over $33,000 to comply with current safety codes. The building completed its mandatory soft-story retrofit in 2016 at a cost of $100,000, demonstrating compliance with seismic safety requirements. Recent maintenance work includes plumbing upgrades with waste line replacement for multiple sinks in 2021 and cold water pipe replacement in 2013. However, there have been several fire safety violations in 2023 related to sleeping area requirements, alarm systems, and fire extinguishers, though some of these violations have been abated. The building has experienced historical issues with heating systems, particularly in 1997 when multiple complaints about lack of heat were filed and subsequently resolved.

The property has a documented history of compliance with various safety and maintenance requirements, including a completed roof replacement in 2018 ($30,000). While there were several building violations recorded between 2001-2005 related to security and fire safety (including issues with fire escape ladders and smoke detectors), these were abated. Recent complaints in 2022 regarding an unpermitted boiler appeared to be resolved quickly. The building has experienced four fire-related incidents between 2019-2023, including a gas leak and several alarm system activations, though none resulted in civilian injuries. A recent short-term rental violation investigation was conducted in 2023-2024, resulting in penalties and cancellation of unauthorized listings. The property demonstrates regular maintenance and upgrades to essential systems, though the recent fire safety violations highlight ongoing compliance requirements in this area.

Risk rating

How 1155 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, 1035 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.

Property class

The assessor's property-class code, which correlates with building type and the violation rates the model expects. This code is grouped with other less-common classes.

12-Month severity forecast
No violation 8.2%
Moderate concern 71.5%
Severe concern 20.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
