Initial analysis

The property at 1564-1566 Underwood Avenue is a one-story, two-unit multi-family residential building located in the Bayview neighborhood, constructed in 1908 and currently owned by Juster & Norita Collins Trust. The building has undergone several significant improvements in recent years, including a complete reroofing project in July 2023 costing $19,900, and a substantial 2018 renovation that transformed a ground-floor studio into a two-bedroom apartment with new kitchen facilities, valued at $94,000. The property has embraced modern upgrades with the installation of a residential solar system scheduled for March 2024 (6.4 kW with batteries), and significant electrical improvements in 2021, including a 200-amp service change-out and rewiring of the second unit. The building's infrastructure has received attention with multiple plumbing upgrades, including rough plumbing work for modern appliances in 2021.

However, recent reports indicate emerging maintenance and infrastructure challenges that merit attention. In late 2024, multiple 311 calls were made regarding the property, including incidents of mold and mildew, plumbing issues (leaks/breaks), and general maintenance concerns, all of which were accepted for review by the Department of Building Inspection. Most critically, there have been three documented sewage back-up incidents in January 2025, affecting the side sewer vent. These recent plumbing and maintenance issues, combined with the property's age and history, suggest that while significant improvements have been made, there may be ongoing infrastructure challenges that require monitoring. The property has also experienced various parking-related incidents in the surrounding area, though these are external to the building itself.

Risk rating

How 1564-1566 Underwood 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.
