On allocating costs

A debate about who should bear the cost of building parking spaces has flared up in Helsinki. When new houses are built, they are required to build a certain amount of parking spaces. This amount is some quota based on the number of apartments built. In downtown Helsinki and the inner-city suburbs this means in practice building underground garages under the houses. This is not a cheap exercise, studies put the average cost per parking space at 40 000 euro. This cost is typically borne by all the apartments in the house, irrespective of whether the inhabitants have a car or not. 

Lately this has lead to some discussion as to whether this is a good system. Today's Helsingin Sanomat interviewed the chairman of the Helsinki City board on the issue. He claims that it would be unreasonable to demand that only those who use the parking spaces would pay for them. Why? "A civil servant or teacher couple cannot afford to pay 40 000 euro, buyt they may still need a car." So therefore the cost of the parking space should be split among all the inhabitants. 

This is a very interesting argument, especially coming from a representative of the main right of center Coalition party. Personally I'd be tempted to extend his argument. 

Consider a house with apartments of two sizes. The larger apartments might be too expensive for the civil servant or teacher couple described by the chairman. The obvious solution is for the owner of the smaller apartment to subsidize the cost of the larger apartment, so that the teacher and civil servant can afford to live there.

Another solution would of course be for those who want a parking space to pay the actual costs of it, and if they cannot afford it, either move to somewhere cheaper, or get rid of their car, if they don't consider it to be worth the cost.
