Parking Ratio Calculator Online
This calculator helps you determine the required number of parking spaces for different types of buildings according to building codes and local planning regulations.
What is a parking ratio?
A parking ratio is a regulatory standard that defines the number of parking spaces required per unit of building area or number of visitors. The ratio depends on:
- Building type (office, shopping center, residential, etc.)
- Location (city center, residential area, suburbs)
- Regional car ownership levels
- Public transportation accessibility
Typical parking coefficients:
- Office buildings: 3-6 spaces per 100 m² of total area
- Shopping centers: 15-25 spaces per 100 m² of retail area
- Residential buildings: 1-2 spaces per apartment
- Restaurants: 10-15 spaces per 100 m² of dining area
- Hotels: 1 space per 2-3 rooms
The calculator considers various factors and provides recommendations for the optimal number of parking spaces for your project.
