Initial analysis

The 10-unit, 3-story multi-family residential building at 555 Corbett Avenue in Twin Peaks, built in 1952 and currently owned by Baumann Family Properties L, has undergone significant renovations and maintenance over the past two decades. Most recently, in January 2024, Unit 5 received substantial bathroom and kitchen renovations worth $30,000, including updates to the 70-year-old bathroom fixtures and kitchen cabinets. The building has seen consistent improvements to individual units, with major renovations in Units 1, 3, 9, and others, typically involving kitchen and bathroom upgrades, electrical rewiring, and modern amenities installation. Important structural improvements include voluntary lateral strengthening work completed in 2016 and multiple deck replacements in 2012, demonstrating attention to building safety and infrastructure.

The property's maintenance history shows regular investment in building systems, including furnace replacements in 2018 and 2012, and various plumbing upgrades. A tenant buyout occurred in April 2020 involving one tenant, though the impact on the building's overall configuration is unclear. The building has undergone routine housing inspections in 1997, 2003, and 2011, all of which were resolved without active violations. The only recorded 311 call was in 2016 for general street cleaning, which was promptly addressed. The property's extensive permit history suggests proactive management, with most recent improvements focusing on modernization and maintenance of individual units rather than structural changes to the building itself.

Risk rating

How 555 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

Out of 172 buildings in this neighborhood, 89 are predicted to be safer.
