Home Improvement Contractors in Hanahan, SC

The median home in the city of Hanahan was built in 1986, newer than the U.S. median of 1980 and older than the South Carolina median of 1992. That is older than the Berkeley County median of 2002.¹ Hanahan's housing is newer than the national mix: 45% of units predate 1980 against 50% nationally, and 15% date from 2010 or later. The largest single share, 34%, dates from 1960-1979. That makes it a newer stock than Berkeley County as a whole (19% built before 1980).¹ On houses from the 1960s and 1970s, the routine checks are aluminum branch wiring, galvanized supply lines and original single-pane windows. Owner-occupied homes in Hanahan are newer than rentals: a median build year of 2000 against 1979.¹ With owner-occupied homes skewing newer, many requests are first-time replacements of original builder-grade components.

Housing in Hanahan is mostly detached single-family: 70% of units, with 16% in buildings of five or more units.¹ A mostly detached stock means the full range of exterior work applies: roofs, garage doors, chimneys and backyard units. 68% of occupied homes in Hanahan are owner-occupied, below the South Carolina share of 72%.¹ The median owner-occupied home in Hanahan is valued at $374,800 (ACS), above the South Carolina median of $259,000. Within Berkeley County the median is $310,300, so Hanahan sits above it.¹ Home values above the state median tend to support fuller scopes; the written scope should still separate must-do from nice-to-have.
