Initial analysis

The three-story, six-unit apartment building at 89-99 Walter Street in Duboce Triangle, owned by the Cefalu-Udin Marital Trust, has undergone several significant maintenance and safety improvements since its construction in 1904. Most recently, in June 2024, the property completed the installation of 51 new vinyl windows in the backyard and stairwell areas. The building achieved compliance with San Francisco's seismic safety requirements through a completed soft-story retrofit in 2016, for which a Certificate of Final Completion was issued. Several major infrastructure improvements have been made in recent years, including a hot water boiler replacement in 2022, a new 200-amp electrical service with seven meters and panels in 2013, and gas pipe upgrades in 2008.

The property has experienced various maintenance issues over the years, with the most recent complaints in 2023-2024 addressing common area maintenance, window condition, and plumbing issues. Multiple violations were recorded in 2023 related to fire safety equipment and building maintenance, though these appear to have been resolved based on the "Not Active" status. Historical complaints dating back to 1996-2002 included concerns about heating, staircase safety, and rear porch maintenance, all of which have been addressed through subsequent repairs and improvements. The building's safety systems are actively maintained, as evidenced by the recent window replacement project and the completed soft-story retrofit. While there have been occasional issues with basic systems (e.g., plumbing and heating), the ownership has generally responded to maintenance needs in a timely manner.

Risk rating

How 89-99 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.

Neighborhood percentile
