Census and NOAA figures for the city of Decatur in Macon County, not the metro, with a source for each.
The median home in the city of Decatur was built in 1960, older than the U.S. median of 1980 and older than the Illinois median of 1971.1 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. The stock is old by national standards: 79% of Decatur's housing units were built before 1980 (U.S. 50%), and only 2% since 2010.1 Pre-1940 houses often have unlined chimneys, plaster walls and balloon framing, which change the scope of almost every trade.
Owner-occupied homes in Decatur are older than rentals: a median build year of 1959 against 1966.1 Where owner-occupied homes skew older, a repair-versus-replace conversation is the usual starting point rather than a like-for-like swap. Housing in Decatur is mostly detached single-family: 74% of units, with 17% 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.
63% of occupied homes in Decatur are owner-occupied (67% statewide).1 The median owner-occupied home in Decatur is valued at $99,600 (ACS), below the Illinois median of $263,300.1 With values below the state median, phased scopes - the essential work first - are a common way to keep a project sensible. Winters are long: the Decatur Ap station averages 113 nights a year at or below 32°F and 43 at or below 20°F.2,3 Long winters put freeze-thaw, ice dams and snow load at the center of roofing and masonry decisions.
Summers bring about 27 days a year at or above 90°F.2,3 Annual precipitation is about 36 inches, with 9 days a year bringing an inch or more.2,3 Heating dominates the year: about 5,393 heating degree days against 1,105 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.
Decatur sits in IECC climate zone 5A (Cold).4 Building permits in Decatur are normally issued by the city building department.5,6
