Census and NOAA figures for the city of New Castle in New Castle County, not the metro, with a source for each.
The stock is old by national standards: 67% of New Castle's housing units were built before 1980 (U.S. 50%), and only 5% since 2010.1 Older housing stock means a contractor's first job is finding what is behind the finish - wiring, plumbing and roof decking - before a price is final. Most housing units in New Castle are not detached houses: 26% are in buildings of five or more units and only 37% are detached single-family homes.1 With most units in multi-family buildings, condo and HOA approvals sit alongside the permit for interior work.
63% of occupied homes in New Castle are owner-occupied (73% statewide).1 The median owner-occupied home in New Castle is valued at $285,100 (ACS), below the Delaware median of $352,000.1 With values below the state median, phased scopes - the essential work first - are a common way to keep a project sensible. The Wilmington New Castle Co Ap station averages 92 nights a year at or below 32°F and 21 at or below 20°F.2,3 A real freeze season means masonry, roofing and exterior sealing are specified for freeze-thaw cycles.
Summer heat is moderate: about 22 days a year reach 90°F.2,3 Rainfall is substantial: about 45 inches a year, 12 days of it an inch or more.2,3 Heavy rainfall makes flashing, drainage and ventilation details the difference between a sound assembly and a wet one. Snowfall averages about 20 inches a year.2,3 Real snowfall means ice-and-water membrane, attic ventilation and roof load are standard parts of a roofing scope.
Heating dominates the year: about 4,647 heating degree days against 1,228 cooling degree days (base 65°F).2,3 In a heating-led climate, insulation and air sealing carry most of the energy-code weight for any work that opens the envelope. New Castle is about 5 miles from the ocean or Gulf coast in a straight line.4,5 Proximity to salt air makes fastener grade and corrosion protection part of every exterior quote.
New Castle sits in IECC climate zone 4A (Mixed-Humid).6 Building permits in New Castle are normally issued by the city building department.7,8
