AI summary

The three-unit residential building at 2628-2630 Leavenworth Street in San Francisco's Russian Hill neighborhood, constructed in 1929, has undergone significant modernization over the past several years under the ownership of the Hans J Zweig Irrevocable Trust. Most recently, in November 2023, the property received a substantial electrical service upgrade to 400 amps with four meters. Earlier renovations include a complete kitchen remodel in 2022 ($40,000), and a significant renovation in 2017 ($124,104) that encompassed multiple units, including bathroom and kitchen updates, high-efficiency fixtures, and new heating systems. The building's infrastructure improvements are notable, including the replacement of three main panels, new grounding systems, and the installation of two new high-efficiency forced air furnaces in 2017.

The property has experienced recurring sewer issues, with documented sewage backup incidents in 2020 and 2022, though these were resolved through municipal intervention. Historical records show earlier structural work including foundation repairs in 1983 and floor repairs in 1985. Several routine housing inspections between 2000 and 2011 were conducted, with no active violations noted. Recent planning inquiries (now cancelled) attempted to explore the legalization of additional units below the garage level, indicating possible undocumented units in the building's history. The building's recent improvements and maintenance record suggest active management, though the recurring sewer issues may be a concern for residents. Two fire alarm activations were recorded, neither resulting in actual fires or civilian injuries.

Risk rating

How 2628-2630 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.
