Initial analysis

The 3440 24th Street property is a three-story, 13-unit multi-family residential building located in the Inner Mission, constructed in 1916 and currently owned by the George A Kardum Sr Trust. The building completed its mandatory soft-story retrofit in 2017 under Tier 3 requirements, implementing seismic improvements that cost $120,000. The building has a history of multiple inspections and violations, particularly in the early 2000s, including significant safety concerns such as fire escape maintenance, security requirements, smoke detection system issues, and general building maintenance problems. Notable inspection issues from 2002 included problems with the fire escape drop ladder, entry door viewers, central alarm system certification, fire proofing materials, smoke detectors, stairs, and gas utility shutoff tools. More recent history shows routine inspections in 2007 and 2015, with no major violations recorded in recent years.

In terms of fire safety, the building experienced several fire-related incidents, though none resulted in injuries or significant damage; these included false alarms and cooking-related incidents. Fire violations from 2005-2006 were resolved and included issues with exit obstruction, fire alarm maintenance, combustible storage, and fire extinguisher maintenance. A series of recent 311 calls (2024-2025) primarily relate to street cleaning issues including garbage debris, while a noise complaint from January 2025 remains open. The property has undergone various maintenance improvements over the decades, including a roof replacement in 1994 and multiple garage-related complaints in 1994 regarding unauthorized use of residential parking spaces for workshop purposes. The most recent fire-related complaints in 2022 regarding fire escape, hazardous materials, and electrical systems were determined to have no merit. The building's historical data suggests that while there were significant safety and maintenance issues in the early 2000s, recent years have shown improved compliance with safety requirements, particularly following the completion of the soft-story retrofit.

Risk rating

How 3440 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.

Model explanation

What's driving this score

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 13.8%
Moderate concern 43.7%
Severe concern 42.5%
