Initial analysis

839 Leavenworth Street is a 5-story, 50-unit multi-family residential building constructed in 1911, currently owned by Sic-mcm 839 Leavenworth Str. The property has undergone significant upgrades and renovations in recent years, including a $83,200 fire alarm system upgrade in 2024 (currently filed) to comply with 2022 codes, and multiple unit renovations between 2016-2020 encompassing kitchen and bathroom improvements in units 102, 201, 303, 304, 307, 508, and 509, with corresponding electrical and plumbing updates. The building has experienced recurring issues with its elevator system, with the most recent complaints in August 2024, and has had multiple fire alarm system-related complaints and violations, including an open violation for sleeping area requirements from November 2023. Historical complaints between 2005-2018 indicated various safety concerns, including issues with fire escapes, handrails, egress obstructions, and a notable 2014 complaint about flooding through the roof causing mildew and mold.

The property has been the subject of illegal short-term rental activity, with violations related to a fraudulent registration that was ultimately abated. Recent building-related complaints include water leakage issues in 2022 and construction-related disturbances in 2020. There is an active permit application for adding two new accessory dwelling units to the rear portion of the basement. Fire safety remains a recurring concern, with documented issues regarding extinguishers and sprinkler systems between 2015-2022, and multiple violations/corrections needed for alarm systems. The building's surrounding area has experienced various maintenance and sanitation challenges, as evidenced by numerous 311 calls for garbage, debris, and encampments between late 2024 and early 2025.

Risk rating

How 839 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 448 buildings in this neighborhood, 372 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 6.1%
Moderate concern 71.3%
Severe concern 22.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
