Initial analysis

The Mcnabola Family Trust owns this 3-unit, 2-story multi-family residential building located at 26-28 Alma Street in the Parnassus/Ashbury Heights neighborhood. Built in 1912, this flats-style building has undergone several significant maintenance and improvement projects over the years, most notably a major renovation in 2014 that included the replacement of T-III siding on one side and back wall with cement siding, along with the installation of twelve new windows (none facing the street) at a cost of $20,000. The property has received regular plumbing maintenance, with records showing water heater replacements in 2020 and 2008, and a sewer repair with house trap work completed in 2018.

The building has a history of routine housing inspections in 2000, 2006, 2009, and 2017, suggesting consistent oversight by housing authorities. A building violation was recorded in 2001 for unauthorized window replacement, though it was resolved by January 2002. More recently, in June 2023, there was one construction noise complaint filed, which was resolved within two weeks. Recent 311 calls (2023-2024) have primarily related to parking issues and tree maintenance, with multiple reports of vehicles blocking driveways, though enforcement officers were often unable to validate the complaints. The most recent building-related service request was for construction noise in June 2023, which was handled through the appropriate regulatory channels. A routine sewer inspection and repair work were completed in 2018, suggesting ongoing attention to the building's infrastructure needs.

Risk rating

How 26-28 Alma 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
