Alabama, with its humid subtropical climate, presents unique considerations for Accessory Dwelling Unit (ADU) construction in areas like Montgomery and Mobile. The warm, wet summers and mild winters influence material choices and build timelines.
Building an ADU in Alabama means accounting for high humidity and potential for heavy rainfall, particularly during spring and summer. This requires robust waterproofing and appropriate foundation work to prevent moisture issues. Local zoning ordinances dictate setback requirements, lot coverage, and the number of ADUs permitted per parcel. Understanding these regulations in cities like Montgomery and Mobile is the first step in the process.
