Initial analysis

The two-story multi-family residential building at 906 Corbett Ave in Twin Peaks, managed by Peaks & Palms LLC, has undergone several significant improvements since its construction in 1964. Most recently, a re-roofing project was completed in July 2024 at a cost of $25,000, marking the building's fifth documented roofing project since 1998. The property has systematically upgraded its windows over the years, with the most recent installations occurring in 2014 across all four units, replacing a total of 14 windows with energy-efficient vinyl options featuring double-pane construction and a U-factor of 0.30. Other notable improvements include the installation of two sliding glass patio doors in 1996 and a major electrical upgrade in 2004 involving an underground service conversion to a 200-amp system with five meters.

The building's maintenance history shows regular attention to infrastructure, with roofing projects spaced approximately every 10-15 years and window upgrades completed systematically across all units. The property has undergone two routine housing inspections, in 2003 and 2011, both of which were resolved promptly with no ongoing issues noted. While the building has had multiple permits issued for various improvements, all work appears to have been completed satisfactorily, with no recorded violations or significant resident complaints. The comprehensive window replacement program and recent re-roofing indicate ongoing investment in maintaining and upgrading the building's systems and comfort features.

Risk rating

How 906 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
