Confirm the town, village, or city and request its building, zoning, occupancy, and code file for the parcel. Match decks, additions, finished areas, garages, retaining work, roofs, pools, and major system changes with local permits and inspections. Then determine whether county shoreland or floodplain jurisdiction applies. Ozaukee County provides mapping and guidance for shoreland areas around navigable waters and for mapped floodplain development in unincorporated areas. The actual distance, boundary, and work matter; a coastal mailing address alone proves nothing about regulatory status or physical condition.
For a private sewage system, collect the county sanitary permit, plan, maintenance history, and repair or replacement documents. Ozaukee County notes that state and county law do not generally require a septic evaluation merely because a property is sold, although a buyer, lender, municipality, or contract may call for one. Do not promise a test is unnecessary without checking those transaction-specific requirements. For a well, use certified testing and applicable state transfer rules. A bluff, ravine, wetland, river, or Lake Michigan setting warrants parcel-specific surveys, mapping, claims, geotechnical or drainage reports, and repair evidence.
Compare both routes using documented obligations. Listing might require local permit closeout, system evaluation, repairs, cleaning, staging, visits, and months of carrying costs. A no-obligation cash offer can reduce preparation, but review the deposit, due-diligence period, cancellation rights, proof of funds, title and costs, closing date, possession, and treatment of the contents. Ask how local permits, shoreland boundaries, septic records, and private access are treated. A clear estimate of what you would keep should also state who handles the local permit, shoreland, septic, and access questions.
