The fire separation distance should be calculated according to the nearest distance to the outer wall of the adjacent building. If there are protruding combustible components on the outer wall, it should be calculated from the outer edge of the protruding part. The parking lot should be calculated from the nearest parking edge close to the building
If the outer wall of the parking garage or repair garage adjacent to the higher side of the building is a fire wall, the fire separation distance is not limited. For buildings with a fire resistance grade of

fire-fighting walls, and the fire resistance limit of the roof of this building is not less than 1.00 hours, or the adjacent higher outer wall door and window openings are equipped with fire protection facilities such as automatically closed fire doors, windows or roller shutters and water curtains, the fire separation distance should be reduced by
, but should not be less than 4 meters.
If the adjacent two outer walls are non-combustible and there are no door and window openings and no exposed combustible eaves, the fire separation distance can be reduced by 25% according to Table 3.2.1
The fire separation distance between the parking garage for art and craft transport vehicles and civil buildings should not be less than
25 meters, and the fire separation distance between important public buildings should not be less than 50 meters. The fire separation distance of the parking garage for Class A goods transport vehicles with open fire or sparks should not be less than 30 meters. The fire separation distance of household garages, rooms and warehouses should be increased by 2 meters according to Table 3.2.1. The fire separation distance between parking garages, repair garages and high-rise civil buildings should be implemented in accordance with the fire separation distance specified in the current "Fire Protection Code for Design of High-rise Civil and Class A Buildings" for Class C and Class C warehouses.
