Part of the answer lies in the number of vehicles entering the system. Metro Manila handled about 2.5 million daily vehicle trips in 2013. By 2023, that number had reached 3.6 million. The metropolis absorbed another 1.1 million daily vehicle movements in just 10 years. The automotive market continues to grow as well. More than 467,000 new vehicles were sold nationwide in 2025.
A standard parking slot measures about 2.5 meters by 5 meters, or 12.5 square meters. One hundred thousand vehicles therefore require roughly 125 hectares of parking area. One million vehicles require approximately 1,250 hectares.
This is a conservative estimate. It accounts only for the parking slots themselves and excludes ramps, aisles, circulation space, landscaping, setbacks and other supporting infrastructure needed to make parking facilities functional. The actual land and cost requirement would be considerably larger.
The problem is not simply building more parking. The problem is also finding land for it. It also follows the same rules as any other real estate market. When demand rises faster than supply, prices increase. Monthly parking rentals in major business districts continue to rise. Condominium parking slots are now commonly sold and leased separately from residential units. This explains why parking is rarely free. Someone ultimately pays for the land, construction, maintenance, lighting, security and operation of that space.
