Builder confidence in the market for newly-built single-family homes edged down one point to a level of 69 in April on the National Association of Home Builders/Wells Fargo Housing Market Index (HMI) but remains on firm ground.

"Strong demand for housing is keeping builders optimistic about future market conditions," said NAHB Chairman Randy Noel, a custom home builder from LaPlace, La. "However, builders are facing supply-side constraints, such as a lack of buildable lots and increasing construction material costs. Tariffs placed on Canadian lumber and other imported products are pushing up prices and hurting housing affordability."
