Initial analysis

The property at 2443-2447 24th Street is a three-story, four-unit multi-family residential building with street-level retail space, constructed in 1905 and currently owned by Frank R. and Shirley A. Stonich. The building has experienced numerous permit-related issues over the past several years, most notably concerning unauthorized basement habitability conversions and ground floor unit legalization. Since 2018, multiple attempts have been made to legalize various improvements, including a second-floor bathroom and a ground floor unit, though some permits expired or were withdrawn, leading to enforcement actions. A significant ongoing concern is the basement conversion project (2022 violation) involving storage rooms converted to habitable space without proper lighting, ventilation, or egress, which remains active as of 2024. The building underwent substantial improvements in 2016-2017, including the installation of a fire sprinkler system, complete electrical upgrades, plumbing renovations, and bathroom remodels across multiple units.

Recent complaints from 2023-2024 have highlighted various concerns, including alleged unauthorized ground floor retail-to-residential conversion, permit violations, and improper garage bin placement. There have been multiple enforcement actions regarding expired permits and unauthorized work, with the most recent being a March 2024 complaint about the expired bathroom legalization permit. The property has a history of compliance issues dating back to 2006-2008, including unauthorized foundation work and permit violations, though these have since been resolved. Recent 311 calls from late 2024/early 2025 primarily involve sidewalk usage and garbage management issues. While many improvement projects have been completed successfully over the years, including the installation of two furnaces, water heaters, and comprehensive electrical upgrades, the building continues to face challenges related to unpermitted modifications and compliance with building codes.

Risk rating

How 2443-2447 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.
