Initial analysis

The property at 231 Delano Avenue is a two-story, 4-unit multi-family residential building located in the Mission Terrace neighborhood, owned by the Idi Torres 2010 Revocable Trust and constructed in 1900. The building has experienced several significant maintenance and compliance issues over its history, most notably in 2002 when multiple violations were documented regarding building safety and maintenance, including problems with stairs, windows, mold, security, and plumbing, though these were all abated by June 2002. There was a fire incident requiring extensive structural repairs in 2005 ($3,500), followed by multiple permit renewals and inspections through 2007. Recent maintenance work includes sewer repairs in 2017 and gas line work in 2015. The building has had recurring issues with parking violations and maintenance concerns, as evidenced by multiple 311 calls in late 2024 regarding illegal parking and driveway blocking. There have also been two instances of graffiti on the property in October 2024 requiring attention. The property has a documented history of construction and modification attempts, including an unauthorized deck that required legalization in 2007, and various code enforcement actions have been taken over the years. The building's infrastructure has undergone various upgrades and repairs, including reroofing in 2004, multiple electrical improvements, and plumbing work, though several permits from 2005-2006 did expire without completion. The most recent significant concerns relate to parking violations and graffiti, while historical issues with deferred maintenance and unauthorized modifications have been addressed through various permits and inspections.

Risk rating

How 231 Delano 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
58th percentile

Out of 149 buildings in this neighborhood, 63 are predicted to be safer.
