Vinyl siding was the most used principle exterior wall material for homes started construction in 2025. This material held just over a quarter share of homes, surpassing stucco for the second time since 2018. The declining share for stucco reflected the slowdown for home building in parts of the Sun Belt. For homes started in 2025, 27.7% had vinyl siding as the principal exterior wall material. Vinyl siding was followed closely by stucco at 24.1%, and by fiber cement siding (such as Hardiplank or Hardiboard) at 22.6%. Each of these materials held about a quarter share of the market, with another sliver held by brick or brick veneer at 16.8%. Far smaller shares of single-family homes started last year had wood or wood products (5.9%) as the principal exterior wall material, while all other materials had a less than 2% share. The strongest trend has been the growing popularity in fiber cement siding.
