Which statement is true about garages used for parking or storage?

The statement regarding garages used for parking or storage being permitted to be unclassified is accurate because garages typically do not meet the criteria for classification required by codes or standards for hazardous or special occupancy. In many jurisdictions, private garages intended solely for the storage of personal vehicles or materials that are not considered hazardous do not need to be classified. This classification often applies to structures that involve specific risks, such as commercial garages that service vehicles or storage areas that deal with hazardous materials.

The other statements are more applicable to different scenarios. For example, classified spaces are often required for areas where hazardous materials are stored or where there is a risk of fire due to the operations being conducted. Fire suppression systems might be mandated in such cases, but standard residential or personal garages do not generally require them unless they house specific hazardous items. Special zoning regulations often apply to commercial operations rather than typical private usage. Thus, the classification as unclassified for a standard garage aligns well with fire and building safety regulations that aim to differentiate between various types of structures and their associated risks.
