Final answer:
Carports must be open on at least two sides for adequate ventilation and to conform to the structural definition differentiating them from garages. The specific number of open sides may vary by local regulations, but this is a general guideline in construction for safety reasons and to prevent the buildup of exhaust gases.
Step-by-step explanation:
The question is related to the construction requirements for a carport. Carports are typically used to provide shelter for vehicles and are a common feature associated with residential houses or parking facilities. There are specific regulations that dictate the design and construction of carports, which can vary depending on local building codes. However, in general terms, carports should be open on at least two sides to ensure adequate ventilation and to qualify structurally as a carport rather than a garage.
This provision is to prevent the buildup of carbon monoxide and other exhaust gases if a vehicle inside is left running. The openness ensures there is enough airflow to disperse any harmful gases. The exact number of open sides required for a carport can depend on specific local regulations, but it is essential for a contractor or homeowner to know these specifications when planning to build a carport.
