Initial analysis

The three-unit multi-family residential building at 249-253 Corbett Avenue in Corona Heights is a single-story structure built in 1914, currently owned by the Waldrup-Tresenfeld Family Revocable Trust. The property has undergone several significant improvements over the years, most recently in 2022 with the installation of a new electrical room and gas meter cabinet. Previous notable upgrades include the 2010 replacement of a wooden roof access ladder with a metal one for firefighter safety, and in 1999, rotted egress stairs were repaired. The building faced several violations in 2002 related to security, fire safety, and sanitation, including issues with handrails, self-closing doors, sliding glass doors, and trash removal, though all were addressed and abated by May 2003.

Recent history shows some ongoing maintenance challenges around the property, with open issues as of late 2024 regarding pavement defects. There have been routine inspections and a complaint about a possible illegal basement unit in 2010, though all complaints have been marked as "Not Active." The building's infrastructure has seen various upgrades, including an attempted underground electrical conversion in 2005, and there was one recorded building fire incident, categorized as unintentional, though no civilian injuries were reported. The property's exterior maintenance has been periodically addressed through 311 calls, primarily concerning street cleaning, graffiti removal, and sewer issues, with the most recent service requests focusing on garbage debris and pavement concerns.

Risk rating

How 249-253 Corbett Ave'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
46th percentile

Out of 348 buildings in this neighborhood, 188 are predicted to be safer.
