Initial analysis

The property at 449 Vermont Street is a two-unit, two-story multi-family residential building constructed in 1906, currently owned by the Krumholz-Hata Family Trust. The building has undergone several significant improvements over its lifetime, including an interior renovation of the second-level living unit in 2004 that involved demolition of existing interior walls and ceiling joints, with associated electrical work also completed that year, costing approximately $25,000. Earlier repairs of note include work on the back stairs and stringers in 1995, though this permit is recorded as expired, and a complete reroofing project in 1989.

A concerning issue has emerged in recent years, with an active housing complaint filed in July 2018 regarding suspicions of an illegal unit due to the absence of a number on the tenant's door. The property is currently experiencing significant external challenges, as evidenced by numerous encampment-related 311 calls between March and September 2024, with multiple reports logged between May and July 2024 alone, though most calls have been marked as unable to locate or closed with various notations. A separate incident involving graffiti was reported and resolved in March 2023. The building's most recent permitted work was completed in 2004, and there have been no major permitted improvements or repairs on record in the past two decades, which may be worth noting given the building's age.

Risk rating

How 449 Vermont 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 726 buildings in this neighborhood, 203 are predicted to be safer.
