Initial analysis

The 5-unit multi-family residential building at 721 Corbett Avenue in Twin Peaks, owned by the Zuger Family Trust, has undergone several significant upgrades and maintenance projects since its construction in 1957. Most recently, in February 2023, exterior stair repairs were completed, involving replacement of less than 50% of the wood with new materials at a cost of $5,000. The property has seen systematic improvements to its carport structure, with a major replacement project initiated in 2017 costing $20,000, followed by design revisions in 2018-2019 that generated some visible building complaints regarding height and scope compliance. The building's maintenance history includes earlier attention to exterior stair safety in 2009, roof replacement in 2001, and the installation of a solar domestic hot water heating system in 1984.

The property has been subject to recent parking-related issues, with multiple enforcement actions recorded between August and December 2024, including several citations for parking on sidewalks and blocked driveways, though some officers were unable to locate violations upon inspection. Two building complaints were filed in the past regarding unauthorized height and fence modifications, though both cases are now listed as not active. The only recorded incident related to fire safety was a smoke detector activation with no fire or injuries recorded. The building has undergone regular housing inspections, with routine inspections in 2003 and 2011 showing compliance with housing standards.

Risk rating

How 721 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
62th percentile

Out of 172 buildings in this neighborhood, 65 are predicted to be safer.
