Initial analysis

The property at 1554-1556 10th Avenue is a 1-story, multi-family residential building constructed in 1906, currently owned by the Yvonne M Sumner Trust and containing two units. The building's maintenance history shows several significant structural and safety improvements, with the most recent being a $25,000 garage strengthening project involving the installation of plywood shear walls and Simpson panels, which was issued in October 2024. Previous repairs include backyard stair repairs due to dry rot in 2022, termite framing replacement at a basement window in 2003, and essential infrastructure work such as a sewer repair in 2016 and gas houseline extension in 2012.

The building has experienced recurring issues with water management, particularly with its drainage systems. Multiple complaints were filed between 2017-2020 regarding problems with rain gutters and roof maintenance, which reportedly caused flooding issues affecting neighboring properties. There was also a complaint in 2022 about an unpermitted patio landing area in the backyard. While these water-related complaints were officially marked as "Not Active," they indicate a historical pattern of maintenance challenges. The property has undergone several necessary repairs over the years, including garage strengthening, stair repairs, and termite remediation, suggesting ongoing attention to structural maintenance. Recent service requests primarily consist of street-level issues such as parking enforcement and abandoned items, which fall outside building-specific concerns. A fire complaint from March 2014 was resolved the same day with no reported ongoing issues.

Risk rating

How 1554-1556 10Th 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.
