Initial analysis

The two-story, 6-unit multi-family residential building at 607 Corbett Avenue in Twin Peaks, owned by Daniel J & Elaine Moriarty, has undergone several significant safety upgrades and maintenance work since the 2016 soft-story retrofit was completed at a cost of $72,000. Recent improvements include a 2023 fire alarm system upgrade adding low-frequency sounders, and in 2022-2023, installation of additional fire safety equipment in the lower level unit A. The property has faced some maintenance challenges, including dry rot repairs to wooden decks and balconies in 2022, and there were two building complaints in late 2022 regarding unpermitted construction work at the rear of the building, though one of these complaints was subsequently abated. The building's history shows consistent maintenance efforts, including roof replacements in 1996, 2001, 2015, and a $250,000 legalization project in 2016, which was ultimately cancelled. The property is classified as a 'nonsprinklered build' and holds a Tier 3 Soft Story retrofit completion status with a Certificate of Final Completion (CFC) issued.

Recent external issues near the property have been documented through 311 calls, particularly regarding reports of debris and parking violations, though these are primarily street-level occurrences rather than direct building-related concerns. The building's fire safety record shows only one minor incident involving a smoke detector malfunction, with no civilian injuries reported during any fire-related responses. The property has undergone routine apartment house inspections in 1999, 2005, and 2010, with a 1996 update regarding previous abatements. A 2004 electrical upgrade included underground service conversion with a 200-amp system and 7 meters. While the building has experienced various maintenance and compliance activities over the years, the most recent permits and inspections indicate ongoing attention to safety systems and structural maintenance.

Risk rating

How 607 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.
