A study out of Johnson C. Smith University in Charlotte finds:

As home prices in Charlotte continue to rise, a study released Friday suggests that some city land-use regulations put affordable housing out of reach for Charlotteans earning a modest income.

The study, commissioned by the Piedmont Public Policy Institute, concluded that housing in Charlotte is unaffordable for families earning 90 percent or less of the city’s median income, or around $52,000 a year from 2010 to 2012. That’s about 140,000 households, according to Census Bureau data from 2010. …

The trio of city land-use policies examined in the study — the stormwater control ordinance, tree ordinance and urban-street design guidelines — add more than $17,000 on average to the cost of a home.

Michael Sanera told ’em so.
