The shortage is also felt most in areas where housing is coming back strongest, and permitting is easiest, like Texas and much of the West. The situation is not nearly as dire in the Northeast, where home building volume is smaller, and it can take years to get a project off zoned and ready to build. Still, as construction across the nation pulls itself off life support, the bitter irony persists. After years of nobody knocking on the door, suddenly this industry is struggling to meet demand."
