The property at 3918-3920 24th Street is a two-unit, two-story multi-family residential building located in Noe Valley, built in 1918 and currently owned by the Lourdes Portillo 2004 Revocable Trust. The building has undergone several significant maintenance and improvement projects over the past three decades, with the most recent work occurring in September 2024 including a furnace and water heater replacement, along with ductwork repairs and associated electrical work. The 2017 electrical upgrade to 400 amp service indicates a modernization effort, while the 2015 kitchen renovation demonstrates ongoing interior improvements.

The property has a history of false alarms and system activations between 2011-2020, primarily related to smoke detectors and alarm systems, with no reported civilian injuries. There are two notable building complaints regarding an empty storefront, one from 2023 (currently active) and another from 2019 (not active). The exterior and immediate vicinity of the building has experienced recurring issues with garbage and debris, with multiple 311 calls in 2024, though these were generally resolved. The building's most recent significant renovation work, scheduled for completion in late 2024, includes substantial mechanical system updates and safety improvements, suggesting active maintenance of building systems and attention to code compliance.

Risk rating

How 3918-3920 24Th 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.
