Initial analysis

The property at 1109-1123 Leavenworth Street is a 5-unit, 3-story multi-family residential building constructed in 1908, currently owned by Leavenworth LLC. The building has experienced several significant maintenance and compliance issues over the past 16 years, most notably in 2023 when multiple complaints were filed regarding unauthorized construction activities in the rear building, including garage conversion and electrical work, leading to an October 2023 permitted project costing $150,000 to legalize unauthorized modifications including 3 bedrooms and 2 bathrooms. There is an active complaint from 2019 regarding broken handrails, difficult-to-open windows, and unresponsive landlord issues. The building has a documented history of water-related problems, including a serious sewage incident in 2007, which was promptly addressed. Between 2009-2010, multiple violations were recorded concerning water damage, damaged ceilings and walls, mold, and building maintenance issues requiring corrections.

More recent infrastructure work includes a 2023 permit for dry rot repair and interior water damage corrections. The property has faced multiple parking-related complaints in 2024, particularly regarding driveway blocking, though these are mostly enforcement-related issues. Several complaints regarding unauthorized short-term rental operations have been investigated and closed, indicating compliance with rental regulations. The building's recent history shows active management of unauthorized modifications through proper permitting as of 2023, though concerns remain regarding the condition of common areas and timely maintenance responses. The property has undergone various improvements over the years, including a kitchen remodel with electrical upgrades in 2007 and various plumbing and maintenance works, though with some permits being filed rather than completed in certain cases. The building's recent history suggests improved compliance with permitting requirements, particularly with the 2023 permit to address previous violations, though ongoing maintenance issues appear to persist based on recent complaints.

Risk rating

How 1109-1123 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.
