The cost of parking is in many cities subsidized and instead appears in housing prices, wages, taxes etc. The effects on other markets are principally well known, but the work on the area is limited. The scope of this paper is how parking norms affect the size of the housing stock. The analysis is based on a model of the rrental-, asset-, and construction markets. Prices and profits are affected when constructors are forced (through parking norms) to build more parking spaces than the customers demand. This decreases the housing stock with 1,2% and increases rents with 2.4% in our example suburb Hägersten.
