Flood and shoreline
Check FEMA maps, local floodplain rules, and any coastal erosion or shoreline permit area before a waterfront or low-lying project.

This is not meant to scare you away from a good house. It is meant to keep a good house good. New York has old housing, wet ground, lakefront, oceanfront, rural wells, city pipes, and mountain lots. A little due diligence goes a long way.
Check FEMA maps, local floodplain rules, and any coastal erosion or shoreline permit area before a waterfront or low-lying project.
A wet backyard, mapped wetland, stream, marsh, or buffer can affect what you can fill, clear, build, or drain.
A clean-looking tap is not a water test. Ask for recent lab results or test before relying on the well.
A septic system is local-health-department territory. Age, capacity, setbacks, and soil matter.
Radon is invisible and testable. A low-cost test is normal due diligence, not a panic button.
Pre-1978 housing deserves a lead-paint question, especially with kids, renovations, or peeling paint.
Start with the property, not the fear. A Long Island coastal home, a Catskills creekside house, a Finger Lakes cottage, a North Country cabin, and a 1920s city rowhouse each deserve different checks.
The smart move is to ask for the right document early: flood map, wetland map, well test, septic record, radon result, lead disclosure, permit history, or local code answer. None of those documents has to ruin the deal. They just help you price and plan it honestly.
For water and septic, start with the county or local health department. For wetlands, shoreline, floodplain, and coastal erosion, start with DEC, FEMA maps, and the local building office. For radon and lead, use state health guidance and a qualified inspector or tester.
