Initial analysis

The 5-unit, 3-story multi-family residential building at 55 Casa Way, constructed in 1937 and currently owned by Casa Way LLC, has undergone several significant system upgrades over the past two decades. Most notably, in 2023, the building underwent a fire alarm replacement system installation costing approximately $36,000 to comply with fire code requirements, followed by a 2024 electrical permit for fire alarm system upgrades. In terms of heating infrastructure, the building received a substantial upgrade in 2021 with the installation of two high-efficiency modular wall-hung boilers and hot water storage tanks, replacing the existing boiler system. Earlier improvements include a complete kitchen remodel in 2004 ($20,000) and significant electrical work including a 400-amp service installation in 2003.

The building has experienced several code compliance issues, particularly in 2003 when violations were recorded regarding heating system performance and fire proofing materials, which were subsequently rectified. There were recurring boiler permit compliance issues in 2011, 2017, and 2022, all of which were addressed through proper system upgrades or corrections. A fire alarm system maintenance issue was noted in 2011, and in 2006, a violation related to a smoke enclosure door was recorded and resolved. Between August and December 2024, there have been multiple reports of garbage and debris on the property, with nine incidents reported to Recology, though these were primarily related to street cleaning rather than building maintenance issues. While the building has had its share of compliance issues, recent upgrades to the fire safety and heating systems indicate ongoing maintenance and improvement efforts by the current ownership.

Risk rating

How 55 Casa Way'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
