Remodeling in Long Island
Long Island's guides use Nassau County as their base, where 34%1 of homes went up in the 1950s alone, many of them Cape Cods and ranches on postwar lots. Permits come from each town or incorporated village rather than the county, and Suffolk County serves as the comparison farther east.
