Census and NOAA figures for the city of Arnold in Jefferson County, not the metro, with a source for each.
The median home in the city of Arnold was built in 1977, older than the U.S. median of 1980 and about the same as the Missouri median of 1978. That is older than the Jefferson County median of 1987.1 Somewhat more of Arnold's housing predates 1980 than the national share: 54% against 50%, with 6% built since 2010. The largest single share, 39%, dates from 1960-1979. That makes it a newer stock than Jefferson County as a whole (41% 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 and rented homes in Arnold are of similar age: median build years 1978 and 1976.1
Housing in Arnold is mostly detached single-family: 79% of units, with 8% 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. Home ownership is the norm in Arnold: 80% of occupied homes are owner-occupied, above the Missouri share of 68%.1 The median owner-occupied home in Arnold is valued at $220,000 (ACS), close to the Missouri median of $230,300. Within Jefferson County the median is $237,200, so Arnold sits below it.1
The Cahokia St Louis Ap station averages 98 nights a year at or below 32°F and 29 at or below 20°F.2,3 A real freeze season means masonry, roofing and exterior sealing are specified for freeze-thaw cycles. Summers bring about 46 days a year at or above 90°F.2,3 Rainfall is substantial: about 41 inches a year, 10 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.
Heating dominates the year: about 4,547 heating degree days against 1,476 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. Arnold sits in IECC climate zone 4A (Mixed-Humid).4 Building permits in Arnold are normally issued by the city building department.5,6
