AI summary

The 4-unit, 2-story apartment building at 908 Corbett Ave in Twin Peaks, built in 1964 and currently owned by the Komberger Trust since September 2017, has undergone several significant improvements over the past decade. The building received substantial maintenance and upgrades, including a $25,000 re-roofing project completed in 2015, kitchen renovations in 2013 (including countertop replacement and electrical panel relocation), and a bathroom remodel in Unit #2 in 2010 that included plumbing and electrical work. The property has maintained compliance with building codes, addressing a violation in 2010 related to unpermitted window and bathroom renovations by completing the necessary updates with proper permits. Earlier improvements included an underground electrical service conversion in 2004 and the installation of emergency lighting in 2003.

Recent activity at the property has been relatively minimal, with only one fire complaint regarding alarm systems in 2013 that was promptly corrected. The building experienced some external maintenance issues in 2022-2023, including reports of graffiti, pavement defects, and damaged property, though these were mostly addressed through regular city services. The property's historical record shows periodic routine inspections in 2003 and 2011, and various street-related issues like parking violations and noise complaints in the surrounding area, which are not directly related to the building's condition or management. The last significant interior improvements on record were completed in 2010-2015, suggesting that while basic maintenance has been maintained, no major interior renovations have been undertaken in recent years.

Risk rating

How 908 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.
