Initial analysis

The three-story multi-family residential building at 80-96 Walter Street in Duboce Triangle, owned by Frank & Lily Ung, was constructed in 1906 and contains 9 units. The property has undergone several significant improvements and faced multiple maintenance challenges over the years. Most notably, the building completed its mandatory soft-story seismic retrofit in 2022 (Tier 3), which included the installation of a ground electrode system in late 2019 as part of the earthquake retrofit. The building has also received important safety upgrades, including a $22,500 reroofing project in 2021 to comply with California Energy Code requirements.

Recent concerns include active violations filed in September 2023 regarding compliance affidavits that remain unresolved as of October 2023. The building has a history of electrical and safety issues, particularly evident in 2007 when multiple complaints were filed about grounding problems, window security, heat, and other maintenance concerns. Fire safety systems have been regularly inspected, with several "no merit" findings regarding fire extinguisher and exit blockages between 2007 and 2020, and only one smoke detector activation incident was recorded without any injuries. The property has maintained compliant housing inspections since resolving previous violations, though recent complaints suggest ongoing monitoring is necessary. The surrounding area has experienced typical urban challenges, with several recent 311 calls recorded in 2023-2024 primarily related to street cleaning and illegal parking, demonstrating active engagement with city services to address local issues.

Risk rating

How 80-96 Walter St'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.
