A Common Pool

New Cobb County, Georgia, zoning rules are expected to make it harder to install any new swimming pools. The rules bar homeowners from building on or paving more than 35 to 40 percent of their property. On an average-size lot, that doesn't leave much room for a pool, after taking into account the house and driveway. "They've essentially told every Cobb County homeowner, particularly if they're in a new subdivision, that they don't own their backyard," Andrew Cook of A Quality Pools told a local TV station.
