Initial analysis

This two-unit residential building at 1278 47th Avenue in San Francisco's Outer Sunset neighborhood, owned by Vincent & Brigitta T Ammann, has undergone significant recent improvements totaling approximately $200,000. Completed in late 2022, the major renovation included transforming garage space into new laundry facilities, a full bathroom, and a master bedroom with dressing area, along with comprehensive upgrades to the kitchen, bathroom, fireplace conversion, and replacement of furnaces and water heater in unit 1278. Between 2023 and 2024, the property has seen extensive system upgrades, including complete rewiring of multiple rooms, installation of recessed lighting, new electrical subpanel, rough-in plumbing work for multiple bathrooms and kitchen, new tankless water heaters, and a new Trane furnace. A roof replacement project was also initiated in 2021 with an estimated cost of $14,800.

The building has previously faced some regulatory scrutiny, including two complaints in 1997 regarding possible illegal dwelling units, though these were resolved within a few months. A minor fire hazard complaint was investigated in January 2020, with no merit found. The property currently has an open tree damage report from December 2024, though this pertains to exterior maintenance rather than building condition. Historical records show a roof deck addition proposal, though this is now classified as closed with no major alterations to the building's structure or unit configuration. The most recent tenant buyout occurred in November 2022, involving two tenants and a payment of $53,000. During the renovation period from 2022 to 2024, the property has demonstrated active maintenance and upgrading of systems, with multiple completed permits indicating ongoing investment in building infrastructure.

Risk rating

How 1278 47Th 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.
