Initial analysis

The three-unit residential building at 443-447 Chestnut Street, owned by the Henry J. Casper Jr. Revocable Trust, was constructed in 1907 and spans three stories. The property has undergone several significant renovations and faced various maintenance challenges over the years. Most notably, in late 2011, the building experienced multiple violations related to habitability, including heating issues, window problems, and interior surface concerns, though these were all addressed by March 2012 through comprehensive renovation work totaling $48,000, which included kitchen remodels, bathroom updates, and the installation of new heating systems. The building has also received attention for structural concerns, with the most recent active complaint from 2022 regarding an unsafe condition at the east side of the rear yard, specifically citing concerns about a neighboring building's substandard second-floor addition. Other notable improvements include a complete reroofing in 2012, rear stairs replacement in 2007, and various plumbing and electrical upgrades. The property has experienced multiple fire alarm activations, though all were determined to be false or due to malfunction, with no civilian injuries reported. Recent history shows regular maintenance and improvements, though the active 2022 complaint suggests ongoing structural monitoring may be necessary. The building's permit history demonstrates active management, with various permits issued for street space usage and property improvements over the years.

Risk rating

How 443-447 Chestnut 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.
