What this due-diligence check covers
Start by identifying the city, county, township, special district or overlay with authority. Then obtain the district, use table and dimensional standards.
Ask the authority about the exact project, including dwelling type, occupancy, animals, business activity and accessory structures.
Why it matters before closing
Zoning can affect whether the project is permitted by right, needs discretionary approval or is prohibited, and it can change the amount of usable land.
Three levels of evidence
First question to resolve
Confirm jurisdiction in writing.
Proof to keep
Preserve written zoning confirmation and connect it to the exact parcel, proposed use and source date.
Escalation trigger
Seller says “unrestricted” without authority confirmation. Ask: Which agency controls this parcel?
