What are the Class I, II, and III classifications of garages?
2 Answers
Garage classifications I, II, III, and IV categorize garages, repair shops, and parking lots based on the number of parking spaces (stalls) and total floor area, divided into four classes (I/II/III/IV). Overview of parking spaces: A parking space, known as a parking-place in English, refers to a designated area for parking vehicles, including both outdoor and indoor locations. Parking spaces can be categorized into two types based on fees: free parking spaces and paid parking spaces. Related to parking space rental: In parking lot management, the primary revenue source for parking lot management companies comes from providing parking services through space rentals and collecting parking fees. Parking spaces are often classified into fixed spaces and temporary rental spaces.
Last time I helped a friend review parking lot design standards, the classification of vehicle garages mainly depends on the number of parking spaces and fire safety requirements. The most basic is the Class III garage, with fewer than 150 parking spaces, where each fire compartment must not exceed 2,600 square meters—common in residential underground parking lots. Class II garages, with fewer than 250 parking spaces, require an automatic sprinkler system, and the fire compartment area can be expanded to 5,200 square meters, often seen in shopping mall basements. Class I garages are more advanced, designed for large-scale parking with over 250 spaces, mandating double evacuation routes and round-the-clock mechanical smoke exhaust systems, similar to those in highway service areas. With the rise of new energy vehicles, new regulations also require fire isolation for electric vehicle parking spaces, and special attention must be paid to zoning when installing charging piles.
