A working group to create a new building law has been set up at Prague City Hall, according to Prague Mayor Adriana Krnáčová, who was speaking at a real estate related conference. Experts agree with city officials that the current system of land-use planning and construction permitting needs to be overhauled. Krnáčová says the lengthy building permit process is one of the main reasons why available apartments are currently lacking in Prague. The short supply leads to sharp increases in housing prices.
