Before you call the county
Most permit applications need the same core set of documents: a site evaluation by a licensed site evaluator or professional engineer, planning materials showing the proposed system and its layout, a plat or survey with the legal description, a confirmed 911 address, the applicable fee, and a recorded affidavit to the public where the system type requires one. Aerobic systems also need an executed maintenance contract.
Details on each step are on the permitting page, and the design page covers what a site evaluation involves.
