Squatters, stolen pipes and broken windows have taken up a lot of police officer Dean Koehnen's time in the past year.
That's because more than 1,000 buildings -- most of them residential -- landed on St. Paul's list of vacant properties between Jan. 1 and Dec. 1. Add that to the 550 that were on the list at the start of 2007, and St. Paul has a costly and visible problem.
More than 2.5 percent of the city's 56,000 residential buildings -- single-family, duplex and multi-unit -- are unoccupied. The concentration of empty buildings in certain neighborhoods and an ever-increasing total -- about 100 more buildings each month -- have city officials and housing advocates trying to figure how to fight blight, crime and declining home values.
"It's definitely a hot topic in the last year," said Koehnen, who is on loan to help the city's code-enforcement department.
"There are absolutely more calls [to vacant buildings], and it is taking more of our resources to look at them," said officer Mark Wiegel, who spends about half his time on housing-related cases.
The city has had an average of 450 vacant buildings per year.
"Is this a problem?" said Nancy Homans, policy director for Mayor Chris Coleman. "Yes."
The problem is not exclusive to St. Paul. Cities across the nation are dealing with the mortgage bust, declining home values and their own unoccupied buildings. But while it might not be exclusive, it is unfamiliar.
