Initial analysis

The three-unit multi-family residential building at 148-150 Mallorca Way in the Marina neighborhood is a two-story structure built in 1950, currently owned by Richard Woo. The building has undergone several significant maintenance and improvement projects over the past two decades, with the most substantial work occurring between 2006-2011, including front wall dry rot repairs, window replacements, and structural improvements such as installing steel beams for window and garage headers, with permits showing expenditures of $40,000 in 2010. A plumbing upgrade in 2013 involved replacing the existing house trap, though this work was relatively minor compared to earlier repairs.

The property experienced notable safety and compliance issues in December 2001, when multiple violations were recorded related to fire safety and security requirements, including concerns about fire extinguishers, fire escape maintenance, combustible storage, and gas meter instructions. However, all these violations were abated by October 31, 2006. More recent activities include a sewage backup incident in 2011 and various street space permits, with the most current building-related concern being a noise complaint in October 2024. While there was an attempt in 2016 to modify the building by adding a third floor and additional parking space, this variance request was ultimately disapproved. The building has maintained its original configuration as a three-unit residential structure, with no recorded fire incidents or other significant problems in recent years.

Risk rating

How 148-150 Mallorca 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.
