Huntsville-specific permitting context
Alabama licenses general contractors at the state level through the Alabama Licensing Board for General Contractors (required for commercial or public projects of $50,000 or more, and residential contractors are separately licensed), and Huntsville's aerospace/defense boom keeps construction demand and pricing above regional norms.
Climate factors: Humid subtropical North Alabama climate with hot summers, mild winters, and Tennessee Valley severe-storm/tornado exposure.
