Census and NOAA figures for the city of St. Louis in St. Louis city, not the metro, with a source for each.
The median home in the city of St. Louis was built in 1938, older than the U.S. median of 1980 and older than the Missouri median of 1978.1 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: 86% of St. Louis's housing units were built before 1980 (U.S. 50%), and only 4% 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 St. Louis are older than rentals: a median build year of 1938 against 1942.1 Where owner-occupied homes skew older, a repair-versus-replace conversation is the usual starting point rather than a like-for-like swap. St. Louis has a mixed housing stock: 43% detached houses, 4% attached or townhouse units and 26% in buildings of five or more units.1 Owners and renters are roughly balanced in St. Louis, with 45% of occupied homes owner-occupied (68% statewide).1
The median owner-occupied home in St. Louis is valued at $197,500 (ACS), below the Missouri median of $230,300.1 With values below the state median, phased scopes - the essential work first - are a common way to keep a project sensible. The St Louis Lambert Intl Ap station averages 85 nights a year at or below 32°F and 26 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 47 days a year at or above 90°F.2,3 Rainfall is substantial: about 42 inches a year, 11 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 17 inches a year.2,3
Heating dominates the year: about 4,433 heating degree days against 1,713 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. St. Louis sits in IECC climate zone 4A (Mixed-Humid).4 Building permits in St. Louis are normally issued by the city, which is not part of a county.5,6
