Yet another sign that the road to bad policy is paved with good intentions: land-use regulations in the Seattle area increase home prices, according to new research from the University of Washington.

"Between 1989 and 2006, the median inflation-adjusted price of a Seattle house rose from $221,000 to $447,800. Fully $200,000 of that increase was the result of land-use regulations, says Theo Eicher — twice the financial impact that regulation has had on other major U.S. cities."

This is consistent with publications produced by other organizations such as the Center of the American Experiment (PDF) and the Heartland Institute.
