Begin with the deed, tax parcel, survey or subdivision map, easements, mortgages, and releases. Niagara County Real Property identifies the local assessors, but the responsible city, town, or village generally keeps building, zoning, certificate, and code records. Request approvals for additions, finished basements, unit changes, roofs, pools, garages, manufactured homes, and trade work. Confirm actual sewer service rather than inferring it from nearby lines or a dense neighborhood.
Where onsite sewage applies, Niagara County Health reviews and approves new-system plans, conducts inspections of existing systems before sale, and reviews certain privately completed dye-test reports. The County describes different designs for soil, groundwater, and site conditions, including raised and sand-filter systems. Collect the original plan, approval, installation evidence, system type, repairs, pumping history, and any transfer evaluation. A sand filter follows a different evaluation process than a typical dye test, and seasonal frozen-ground conditions can affect testing. For a private well, keep construction and recent laboratory records and confirm separation from wastewater components.
Set the comparison around the actual calendar and file. A listing may involve municipal searches, health review, a seasonally timed test, repairs, cleanout, showings, and continued taxes, insurance, utilities, and loan costs. For an as-is proposal, examine deposit, inspection and cancellation terms, funding, title objections, closing expenses, extensions, possession, and remaining contents. Ask in writing whether the buyer requires a county evaluation before closing and who addresses an adverse or incomplete result. Do not describe groundwater, sewage failure, or flood history without direct evidence.
